Aluminum, copper, and brass are valuable raw materials—but they are difficult to separate from a mixed waste stream because they are not magnetic. This is where the eddy current magnet, or eddy current separator, comes into play. The technology is elegant and effective, and it can turn what previously went to landfills or incineration into a direct source of revenue.

The principle: rotating magnets create a repulsive force

An eddy current magnet consists of a rotating core made of powerful neodymium magnets. When a non-magnetic (or very weakly magnetic) conductive material—such as a piece of aluminum—passes over the core, eddy currents are induced in the metal. These currents repel the metal away from the conveyor belt, creating a separate fraction.

The result is that metal can be separated from plastic, wood, stone, and other materials with high precision—down to particles as small as 0.5 mm. The lighter and more electrically conductive the metal is, the more effective the separation process. Aluminum is one of the easiest materials to separate using this technology, but copper and brass are also separated effectively. Choosing the right magnet for the material involves starting with a proper analysis of the material, which determines the magnet type, number of Gauss, and other factors. This knowledge is crucial for achieving the maximum metal recovery rate.

Why is it economically important to recycle these metals?

Aluminum recycling is one of the most energy-efficient processes in the entire recycling industry. It requires only a fraction of the energy needed to produce aluminum from bauxite. In Sweden, it is estimated that aluminum worth nearly two billion kronor is lost each year due to inadequate sorting—a cost that can largely be avoided with the right technology.

Similar figures apply to copper: recycling saves up to 85 percent of the energy required for new production, and the recycled material retains nearly its full value. Brass and other alloys offer even greater benefits.

In short: every part per thousand of these metals recovered from the waste stream adds direct economic value.

Applications

• Bottom ash from waste incineration — recovery of metals that would otherwise be lost
• Construction and demolition waste — copper, aluminum, and brass from installations
• Crushed materials — metals are released during crushing and can then be separated
• Park and garden waste containing metal objects
• Industrial waste containing metal residues

Integration into your line

An eddy current magnet works best when the incoming material is the correct size and relatively free of coarse contaminants. For this reason, it is typically placed after a Screening plants a crusher, and is often combined with an overhead magnet that handles the magnetic metals (iron and steel) in a first step. Norditek’s eddy current magnets are available in three basic sizes and can be directly connected to, for example, a Screening plants a compact and efficient system flow.

Summary

An eddy current magnet is an investment that often pays for itself quickly—the metals it recovers quickly add up. When properly sized and integrated into your production line, it can make a significant difference in your recovery rate and revenue.

Please contact us at Norditek if you’d like to test the technology on your own materials. We’ll conduct test runs and help you determine the right specifications.

Any fraction containing plastic, paper, or wood chips reduces the value of the entire material—no matter how efficient the sorting plant is. the wind shifter is the solution. It uses air as a separation technique and removes light contaminants with extremely high precision, without disturbing the heavier materials. It is a module that may not be as visible as crushers and Screening plants, but whose contribution to the purity of the final product is invaluable. Two out of three recycling projects windshifter itek windshifter customers windshifter a windshifter . It is simply crucial for increasing the recycling rate and profitability in many of our projects.

How the wind shifter

The material is fed into a single-layer system against a controlled air flow at the correct speed. Heavy particles—such as stones, gravel, metal, and wood chips of the appropriate density—fall through the air stream and are collected in one fraction. Light materials, such as plastic film, paper, leaves, and light organic matter, are carried along by the air flow and collected in a separate container.

The air velocity and dispersion are adjustable, which means the operator can fine-tune the separation threshold depending on the material being processed. This makes the wind shifter enough to handle everything from crushed construction waste to compostable materials and biomass. There are five parameters to adjust, and the appropriate presets for the application are selected based on the material.

Why are pure fractions critical to business?

Material buyers are setting increasingly stringent requirements for the purity of incoming materials. Wood fractions containing plastic are not accepted for biochar production. Scrap metal mixed with paper and plastic fetches a lower selling price. Crushed concrete containing pieces of wood or plastic may be rejected.

Purifying the fractions upstream—right on the production line—is more cost-effective than removing impurities at a later stage or being forced to sell the material at a lower price.

the wind shifter seamlessly with Screening plants crushers. A typical sequence might look like this:

• The crusher reduces the feed size
• Screening plants materials into size fractions
• windshifter light contaminants from relevant fractions
• A magnet or eddy current detector detects the metal content
• water bath be added for density separation if necessary

Norditek's wind sorters are designed to integrate seamlessly with the other modules in the product range. This results in shorter downtime, easier maintenance, and a more predictable production line.

Applications

• Recycled wood — separates plastic and light contaminants from the wood fraction
• Park and garden waste — separating the organic fraction for biochar production
• Construction waste — separates crushed concrete and brick from lightly contaminated material
• Excavated material — removes lighter organic matter

Summary

The basic principle: sort materials by size

A Screening plants sometimes called a screening unit or screen—separates incoming material into different fractions based on particle size. The material is fed into the plant and passed over a screen deck with holes of defined sizes. Material smaller than the holes falls through and forms an under-fraction, while coarser material continues on as an over-fraction.

Depending on the material and the desired level of precision, different screening techniques are selected: drum screens rotate the material inside a cylinder, star screens are ideal for moist and sticky organic fractions, and flip-flow screens are highly effective for slightly tougher materials.

Flip Flow — the technology that solves the problem of hard-to-sort materials

One of the most interesting innovations in recent years is flip-flow technology. Traditional screening decks can become clogged when the material is damp, fine, or elastic. The flip-flow screen solves this by moving the screening deck in a wave-like motion at a high frequency. This lifts and tosses the material, preventing clogging and providing cleaner separation—even with difficult materials such as wet construction debris, composted food waste, or plastic-rich waste.

The Norditek ES5200 is an example of a modern Screening plants can be operated with either a flip-flow box or a rock box, depending on the application. The expanded screening surface produces cleaner fractions, and the smart sequence control can drive multiple modules from a single unit.

The sorting plant in the system

One of the biggest misconceptions is that the sorting plant is a standalone machine. In reality, it is a hub in our modular system. A crusher is often located upstream of the sorting plant to ensure the correct feed size. Downstream, a windshifter can windshifter light contaminants such as plastic and paper, a magnet can handle ferrous materials, and a water bath materials based on density.

The better these modules communicate with each other—mechanically, electrically, and in terms of material flow—the higher the overall recovery rate will be, and the cleaner the fractions you’ll end up with.

What should you consider when choosing Screening plants?

• What type of material will be handled? (construction waste, excavated material, organic waste, etc.)
• On average, how moist and sticky is the fraction?
• What particle sizes do you need?
• Should the machine be mobile or stationary?
• Does it need to integrate with existing modules in your system?

The correct answers to these questions determine the choice of screen type, screen area, and drive system. A design tailored to your specific material flow makes a significant difference in terms of uptime, energy consumption, and maintenance costs.

Summary

A sorting plant is not just a machine—it is a strategic investment that determines how much value you can extract from your waste streams. With the right technology, the right size, and the right integration into your system, you can increase your recycling rate, lower your operating costs, and deliver cleaner materials to the market.

Crushing and screening give you control over particle size. Magnets and windshifter metals and light contaminants. But what do you do with materials that are the same size but have completely different densities—such as concrete mixed with wood, for example? This is where the water bath is unmatched. By taking advantage of the fact that different materials float at different depths, the technology can separate fractions that are nearly impossible to separate using mechanical or air-based methods.

The Principle: Archimedes' Principle on an industrial scale

The water bath takes advantage of the fact that materials with different densities behave differently in water. Light materials—plastic, wood, and lighter organic materials—float on the surface. Heavy materials—concrete, stone, brick, and metal—sink to the bottom. Materials in the middle can be separated depending on the settings.

This seemingly simple principle enables separations with a level of purity that is difficult to achieve by other means. The result is fractions with a purity high enough to be sold as raw materials rather than classified as waste.

Application: construction waste

Construction waste is one of the most suitable materials for water treatment. Incoming construction waste typically contains a mixture of concrete, brick, wood, plastic, and metals. After crushing and screening, there is still a mixed fraction that is difficult to process mechanically. The water bath solves this problem: the wood floats to the surface, the concrete sinks, and the plastic fraction can be collected from the surface.

In a collaborative project with Ragn-Sells Häradsudden, Norditek demonstrated how adding a water bath the production line made it possible to sort more and cleaner fractions from construction waste—fractions that previously ended up in landfills.

Application: sand for road maintenance

When processing street sweepings, the input material often contains a mixture of sand, gravel, and organic matter. But it also includes inorganic materials such as plastic, snuff boxes, and all sorts of items discarded on our streets. Using a water bath , these water bath be separated efficiently, enabling the sand fraction to be reused for the next season. The same method is also used for similar applications instead of sending the material to a landfill.

Energy and the Environment

Water-based separation processes are relatively energy-efficient compared to thermal or chemical alternatives. The water can often be recirculated within the system, which minimizes consumption. From an environmental perspective, this technology helps keep more materials in the cycle and reduces the need for virgin raw materials.

Integration

The water bath is normally placed last or second to last in the production line—after the crusher, Screening plants and windshifter. Norditek’s modular concept allows the water bath to be integrated with other machines in the range without complicated modifications.

Summary

The water bath is one of the most effective methods for achieving the purity levels required by the materials market and regulatory standards. It is the technology that transforms mixed waste fractions into marketable raw materials. Would you like to learn more about how a water bath fit into your production line? Contact us at Norditek.

The recycling industry is changing rapidly. Regulatory requirements are becoming stricter, material markets are demanding higher levels of purity, and municipalities are expected to take on an increasing amount of responsibility for ensuring that materials are actually recycled—not just collected. In this context, flexibility and scalability are crucial. This is the essence of a modular approach: building a production line that can be adapted as conditions change, without having to tear everything down and start over.

What does "modular recycling" mean?

A modular recycling line consists of machines designed to work together—mechanically, electrically, and in terms of material flow. Each module performs a specific task: crushers reduce material size, Screening plants fractions, air screens remove light contaminants, magnets sort out metals, and water bath materials by density.

The key point is that these modules can be combined and replaced individually. If the material flow changes—for example, if a new fraction is added or capacity requirements increase—a new module can be added without having to rebuild the entire line.

Benefits for municipalities

For municipalities with limited investment budgets, the modular approach is particularly valuable. The investment can be made in stages: start with the most critical modules for the most common material flows and expand as needs and the budget allow. This reduces the initial capital risk and makes it easier to justify the investment internally.

The modular system also simplifies the procurement process: it allows you to specify functional requirements for each module, compare alternatives, and ensure that individual components meet the requirements without being locked into a single vendor’s system.

Benefits for recycling companies

For private operators, the key factors are flexibility and profitability. A recycling line that can be quickly reconfigured for a new material—or scaled up to increase capacity—provides a clear competitive advantage. Modular systems also make it possible to rent, lease, or purchase machines depending on the business model and the long-term reliability of the material supply.

Example: a complete line for construction waste

A typical scenario at a recycling facility that handles construction waste might look like this:

• A jaw crusher or impact crusher reduces the feed material to a manageable size
• Screening plants flip-flow technology separate fractions by size
• windshifter plastic, paper, and light organic contaminants
• Overhead magnet handles iron and steel
• An eddy current magnet separates aluminum, copper, and brass
• water bath the remaining mixed fraction by density

Each step in the process increases the purity of the final fractions and boosts their market value. The system can be started with just a few modules and expanded as needed.

Future-proofing

Perhaps the most important feature of a modular system is its ability to adapt to future requirements. The EU’s stricter regulations regarding packaging and construction waste, among other things, mean that material recycling requirements will increase in the coming years. A facility that is currently designed to meet these requirements—and that can be scaled up as they become even stricter—is a strategic asset.

The mobile plant enables very rapid setup of a system for washing and recycling excavated material. The washing system is a fully container-based and modular system that can be set up quickly and offers high flexibility. The system consists oftwo 40-foot containers, the smallest configuration of any complete washing plant, making it particularly suitable for project-based recycling. 

The delivery also includesa water treatment system for recycling process water, which minimizes water consumption and enhances the overall effectiveness of the solution.

“We’re seeing a rapidly growing market for the recycling of excavated material. Demands are increasing, but so are the opportunities. With new technology, it’s possible to turn material that was previously considered waste into a resource, andthis washing system is a prime example of such technology,” says Daniel Carlberg, CEO of Norditek Group.

The modular solution is tailored to the customer’s project volumes and can be supplemented with sorting and air separation to create a complete process. The combination of mobility, a relatively low capital investment, and rapid commissioning makes this technology particularly attractive in today’s market.

This delivery is one of several similar washing solutions in a short period of time, confirming a clear increase in demand. According to Norditek, there is significant market potential in processing excavated material locally—in infrastructure, construction, and recycling—where large volumes are still sent to landfills or used for low-value applications.

“The fact that decisions are being made more quickly now shows that the market is maturing. More players are recognizing the business value of taking control of both their own and others’ data,” says Peter Macina, Business Area Manager at Norditek.

Norditek believes that the field of washing and processing excavated material will be one of the fastest-growing segments in materials recycling in the coming years.

Learn more about washing equipment for excavated material

We have methods for recycling excavated material directly on-site or converting it into marketable products at a facility, rather than simply sending it to a landfill. The main advantage of washing excavated material is that the method is relatively simple and allows for quick recycling when the material does not contain complex contaminants. However, most contaminants can be removed as long as the right method is chosen.

Laundry equipment that gets the job done

Norditek specializes in modular washing plants that are flexible and mobile, making them suitable even for smaller-scale operations. This makes it possible to recycle excavated material into sand and gravel even in projects that would otherwise lack the financial resources for a large, permanent facility.

Mobile laundry equipment has several advantages:

• Capability to handle muddy and sticky materials:Our washing plants can process muddy and sticky materials and recover very fine fractions.
• Particle sizes down to 0.1 mm:Norditek’s modular system makes it possible to produce particle sizes down to 0.1 mm. The result is clean, high-quality sand and gravel.
• Scalable and modular:The systems can be expanded from simple recycling to more advanced sorting and are compatible with Norditek’s Screening plants air classifiers.
• Lower investment:The mobile recycling plant requires a relatively small investment and offers greater flexibility because it can be adapted to the composition of the materials.

In addition to washing, Norditek also offers Screening plants, air separators, magnets, and belt conveyors that work in conjunction with the washing systems to create a complete recycling process.

The right method for the right materials

Excavated material may contain clay, silt, sand, gravel, stone, and various contaminants. Depending on the composition, both wet and dry methods are available to enable the reuse of the material in other projects. It is therefore important to begin with an analysis of the material’s composition in order to select the right combination of screening, crushing, washing, and separation. A thorough analysis reveals what can be recycled and what requires further processing.

Examples of materials suitable for washing:

• Mixed soil with gravel, sand, or geotextile 
• Contaminated soil (e.g., metals or chemicals) 
• Loose soil with a high clay or moisture content 
• Soil mixed with organic matter, stones, or metal 

When the right screening media are used for parameters such as moisture content, clay content, and roots, production can be optimized and recycling improved.

Examples of projects and development trends

Norditek, together with its partners, has developed a washing process that combines dry screening and washing. The process increases capacity and water efficiency while ensuring a high-quality end product. In the dry stage, large stones and clay are sorted out to increase capacity and reduce water consumption—the clay then does not need to be washed. Afterward, all iron is separated before washing begins. The washing process itself removes silt, clay, and contaminants such as textiles, wood, and plastic, leaving behind clean sand and stone completely free of impurities. The wash water is purified in a sedimentation basin and then returned to the process, allowing up to 90% of the water to be reused.

This process allows contaminated material to be reused in infrastructure projects instead of being sent to landfills. Ragn-Sells points out that washing and reusing soil reduces the burden on landfills and increases the supply of recycled aggregate. The goal is to meet cities’ climate targets, such as Gothenburg’s ambition to use at least 50% recycled aggregate by 2030.

Summary and Next Steps

Washing excavated material is the key to transforming problematic waste into a valuable resource. With modern washing solutions, modular facilities, and the right analysis, you can:

• Extract clean fractions of sand, gravel, and stone from materials that would otherwise have been sent to a landfill.
• Reduce the number of trips, save money, and achieve significant environmental benefits.
• Scale capacity up or down depending on the size and needs of the project.
• Help Sweden achieve its goals of increasing ballast recycling and reducing its carbon footprint.

Norditek offers flexible washing solutions that can be adapted to different types of soil and projects. Would you like to learn more about how to recycle excavated soil, contaminated soil, or production waste? Contact us for a customized solution.

A development is currently underway in Denmark that could transform the way we manage excavated material, sludge, and soil contamination throughout the Nordic region. Using Backer’s new mixing technology, companies have begun stabilizing roads, capping landfills, and reusing materials on-site—with a mixing precision of up to 1%.

The results have been so successful that the Danish government now sees hundreds of millions in potential savings, and the issue has reached the political level. The technology is environmentally friendly, resource-efficient, and circular—and ready to be introduced in Sweden.

Technology at a Glance

Backer’s mixing system enables continuous, precise, and reliable mixing of soil, sludge, and waste materials. Unlike traditional methods, the mixer can also handle unscreened and uneven material—without any downtime.

The system combines sorting and feeding into an integrated process that provides full control over the blending. The recipe—which may include lime, bentonite, biochar, or ash—is developed in collaboration with the customer based on the material’s properties and the desired outcome.

Applications

• Soil stabilization and soil improvement– ensures that roads, noise barriers, and construction sites remain stable even in poor soil conditions.
• Final capping of landfills– mix bentonite and soil to create impermeable, secure surface layers.
• PFAS and other contaminants– stabilize and bind hazardous substances in the soil to prevent leaching.
• Reuse of dredged material, clay, and excavated material– reduce transportation and the need for virgin material.
• Rehabilitation of contaminated industrial sites—such as old sawmills—into developable land.

Why this is important for Sweden

Currently, there is a lack of large-scale solutions for precise and continuous mixing of materials. This technology opens up entirely new possibilities for:

• reduce the amount of waste sent to landfills,
• reuse local materials,
• meet climate goals by reducing transportation,
• reduce the costs of excavation and restoration work.

Germany already has legal requirements for local waste management, and Denmark is leading the way. Sweden now has the opportunity to follow suit—with Norditek and Backers at the forefront.

Next step

Starting next week, Our will be available. We are planning demonstrations and test runs where you can see exactly how mixing works in practice.

 – What's happening right now?

There are new developments every day at our new headquarters, which is currently taking shape. This includes not only the buildings that ‘BRA bygg’ is constructing for us, but also the lab and testing environment that is coming together. There, we will soon be testing, developing, and building even better recycling processes together with our customers.

-Why is it so good?

This is one of Norditek’s biggest efficiency improvements to date. Previously, we could spend weeks testing materials that “might” be recyclable. But now we’re becoming so accurate with Our that a quick material analysis is often enough to determine whether a project is viable—or should be scrapped. We’ve simply become really good at saying no—or yes! With the new testing environment, we’re taking another step forward and can work with more materials, waste, and contaminants. We’re becoming even more accurate in both rapid analysis and full-scale testing.

-What else is coming up?

Next week we’ll be releasing Our , which will show how the year actually went—it’s going to be really exciting! In it, we’ll also share more about everything that’s in the works.

The starting point: understanding the material

Every wood waste stream is unique. To find the most cost-effective solution, you need to assess:

• Type and volume of material– clean wood, contaminated reclaimed wood, bark, sawmill waste, or forest waste.
• Contaminants– metal, glass, stone, or plastic that can cause equipment downtime or high ash levels.
• End use– wood chips, pellets, landscaping soil, or raw material for new production.

Only when the goal is clear can the right technique be chosen.

The solution first—machines last

Norditek presents its"Norditektrappan" method: a process that always starts with the solution and the properties of the material before selecting equipment. This creates flexible and cost-effective systems for municipalities, recycling companies, sawmills, and forestry companies.

Three key takeaways from the webinar

1. Construction and demolition waste

The goal here is to produce a clean wood fraction for energy recovery.

• Coarse crushingof the material.
• Magnetic and eddy current separationremoves iron and aluminum.
• windshifter water bathseparate stone, glass, and concrete.

The result is wood chips with a lower ash content, fewer production stoppages, and higher boiler efficiency—plus revenue from recycled metal.

2. Contaminated reclaimed wood

For heavily contaminated streams, the focus is on developing a fuel that reduces ash formation.

• The right pretreatment can reduce bottom ash by up to50%and savemillions in boiler operating costs.
• At the same time, the technology releases metals for recycling.

3. Forest waste, bark, and sawmill residues

The goal here is to produce biofuel with a high energy content.

• Crushing and star screeningseparate soil and fine material from coarser material.
• The double windshifterremoves any remaining gravel and stones.

Examples from the webinar show that sawmills have been able to reduce costs by60–70%by processing bark waste into a marketable biofuel fraction.

From Problem to Business

With the right technology, you can:

• Save a lot of money by reducing downtime and ash handling.
• Generate new revenue from metals and clean biofuels.
• Reduce transportation and establish local material flows.

Practical next steps

Norditek will encourage participants to start with their own analysis:

Which material flows are the most pressing? What drives value—reduced landfill, fuel production, or on-site reuse?

Based on this, a modular solution can be built that combines a crusher, screen, magnet, and windshifter needed.

Register for: Webinar: Recycling Various Types of Wood Waste and Wood Materials – October 3

https://events.teams.microsoft.com/event/820946d8-cb49-46a2-bf83-7f0495537503@519d6e25-0e6d-4b79-986a-b92d97fa92ad

Every year, construction and demolition projects generate enormous amountsof wood waste. It is often viewed simply as a cost to dispose of—but with propersorting,the material can instead be resold and generate revenue. This makes wood waste a valuable resource in the circular economy.

Different types of wood waste and their value

To successfullyrecycle wood waste, it is important to understand the different categories:

Solid wood (Grade A wood)

Untreated wood with high market value. Used aswood biofuel, pellets, or raw material for new building panels or furniture.

Painted or varnished wood (Class B wood)

Commonly found in demolition debris. After proper sorting, it can be used as fuel in heating plants. It can be separated from other clean wood through optical sorting.

Pressure-treated wood (Class C wood)

Contains chemicals and requires special handling. It has no direct economic value, but proper handling protects the environment.

Composite materials and furniture

Often contains wood, plastic, and metal. With modernsorting technology, these materials can be separated for recycling.

Economic benefits of wood recycling

Simply sending wood to a landfill is expensive. Byrecycling wood, companies can instead:

• Reduce landfill costs.
• Sell wood wasteas a raw material to heating plants, pellet manufacturers, or producers of building materials.
• Increase profitabilityby supplying high-quality, clean materials.

With the right strategy, wood waste doesn’t have to be a burden—it can be a profitable business.

Sorting machines that increase the value of wood waste

The key to success lies in the technology. With Norditek’s wood sorting machines, companies can:

• Separate Grade A lumber from Grade B and C lumber.
• Remove plastic, metal, and other unwanted materials.
• Deliver a product that meets market requirements.

In this way, wood waste is transformed into a resource that both reduces the environmental impact and strengthens the company’s business.

Conclusion: Wood waste as a resource in the circular economy

Recycling wood wasteisn’t just about the environment—it’s about the bottom line. Bysorting wood efficiently, companies can turn costs into revenue and contribute to a more sustainable future.

Yep, you heard right. Choosing the wrong machine is easy. A surefire way to choose the wrong machine is to simply start by looking for the machine you need. Choosing the right recycling machine isn’t about starting with the machine—it’s about understanding the material. Amaterial testgives you a clear picture of what you can get out of it, how clean it will be, and what it’s worth. That’s where you build your business.

Whether you’re dealing with excavated soil, demolition debris, industrial waste, biomass, or any other type of waste material, you should always start with a simple question:

What's in my material—and what can I do with it?

1. The material test demonstrates the potential of your flow

A material test provides answers to three crucial questions:

• What can be separated?In which fractions are the contaminants found? Such as plastic, soil, stone, wood, or metal.
• What technology can be used?Can pollutants be separated based on size, weight, density, aerodynamics, external characteristics (sensor technology)—or a combination of these factors?
• How pure are the fractions?And how can they be used or resold?

The test provides you with a solid foundation for moving forward with a needs analysis, proposed solutions, and a cost estimate. With that information in hand, you’ll receive a proposed solution within two weeks—based on your actual materials.

2. The volume handled determines capacity requirements

Once you know what the material contains, the next step is to considerhow much of ityou handle and how often.

• One-time flows or project-based?In that case, a mobile solution is often the best choice.
• Large, continuous flows?In that case, stationary is more efficient over time, though it can still consist of mobile machines.
• Need scalability?Modular solutions can provide the flexibility to grow.

We’ll help you scale the right solution for your volumes—and avoid over- or undercapacity.

3. The conditions on site determine which solution works

The sorting solution must work in practice, not just on paper. That’s why we’re looking at:

• Space and accessibility:Is there electricity? How much space do you have?
• Site conditions and logistics:Does the facility need to be moved frequently? Does it need to withstand winter weather?
• Integration:Should sorting be combined with crushing or other further processing?

This affects both the choice of equipment and the installation solution.

4. The purpose of the material determines its value

What will the material be used for?

• On-site reuse(e.g., base course, fill material)
• Sales of products(e.g., combustible materials, metals, recycled soil)
• Lower costs for hauling away or landfilling

Yourvalue isn’t created by the sorting process itself, but by what you can do with the sorted materials. That’s why we always start withthe end usein mind when developing a proposal.

Wood recycling – from waste to raw material

Wood recycling is a key component of the circular economy—but it requires smart solutions to succeed. At Norditek, we developmobile sorting solutionsthat make it possible to manage wood waste in an efficient, profitable, and sustainable way.

What is the challenge of wood recycling?

Wood waste often contains contaminants such as:

• Plastic
• Stone and sand
• Iron, aluminum, and precious metals
• Moisture and dirt

In order to recycle wood as a material or use it as fuel in bioenergy plants, these materials must be sorted out—with high precision.

Many biogas production facilities generate a residual material—a contaminated by-product filled with plastic, organic matter, and other contaminants. This material is often viewed as hazardous waste destined for landfills or incineration. At Norditek, we see something different: the opportunity to separate, process, and recycle.

In this video, we show how contaminated waste can be transformed into clean fractions that provide both economic and environmental benefits.

What is biogas production waste?

Digestate is what remains after organic material has been converted into biogas. It often contains plastic debris, soil, and other contaminants that make it difficult to recycle.

The challenge – and why it matters:

Managing rejects in a sustainable and profitable way has several advantages:

• Reduced landfill costs

• Reduced environmental impact

• Increased resource efficiency

• Ability to collect plastic and organic materials for recycling and energy recovery

Our :

Through test runs, material analysis, and the use of flexible machine systems, we can:

• Separate plastic from organic waste and soil

• Create clean fractions for recycling

• Optimize processes to suit each individual material flow

A concrete example:

In a recent test run, we processed a byproduct from biogas production with a high level of contamination. The result:

• Clean soil fraction

• Plastic removal

• Significantly reduced waste sent to incineration

The potential for additional material streams:

We know that many material streams in Sweden and the Nordic region hold untapped potential. Whether it’s biogas residues, excavated material, bioash, or other difficult-to-process materials—with the right pretreatment, much more can be recovered.

Would you like to know what you can do with your material?

We offer material testing services in which we analyze and calculate the potential for recycling and processing. Contact us and send us a photo or a material sample—we’ll determine what’s possible.

Norditek has signed an agreement with BRA Bygg for the construction of the Norditek Recycling Lab—a project that, once completed, will represent a major step forward in the development of new solutions for recycling and circular flows. Construction will begin in the first quarter of 2025 and will have a strong circular focus.

– To practice what we preach, both the construction process and project execution will place an equally strong emphasis on circularity. Together with BRA Bygg, we will use recycled materials throughout the entire project—from groundwork to the finished buildings. This involves recycled fill, recycled steel, reused brick, and wood. Fill management is particularly interesting because it has often been an overlooked part of construction projects, even though we see that this specific aspect can provide the greatest climate benefits, says Daniel Carlberg, CEO of Norditek.

A center for testing, training, and innovation

The Norditek Recycling Lab will consist of three integrated buildings housing testing labs, training facilities, offices, and machine demonstration areas. The buildings have a total floor area of 1,350 square meters and a volume of 6,000 cubic meters.

“For us at BRA Bygg, this is an exciting project for two reasons. First, we’re gaining a deeper understanding of the processes involved in circular material management, and second, we’re getting the opportunity to put circular construction into practice,” says Magnus Andersson of BRA Bygg.

Norditek has long been working to facilitate the recycling of excavated material, industrial waste, and other material streams. With the Norditek Recycling Lab, the company is taking the next step by focusing on developing the recycling process itself—with the goal of enabling more recycling projects than ever before.

“This is a project where we at Norditek really get to show what we stand for. We don’t just create smart recycling solutions—we ensure that materials are actually given a new lease on life in new projects. With the Norditek Recycling Lab, we also gain a space where we can test, educate, and demonstrate the recycling of the future,” says Daniel Carlberg.

The Norditek Recycling Lab is being built in Duvehed, Kungsbacka Municipality.

Excavated material can be a resource or a problem—it all depends on how it’s managed. Unfortunately, we often see people falling into pitfalls that make the process more expensive, inefficient, and less sustainable. Here are the three biggest mistakes—and what you can do instead.

❌ 1. Relying on landfills as the default solution

The problem:Transporting excavated material to a landfill may seem like a quick fix—but it’s expensive and often unnecessary. Furthermore, regulations are constantly becoming stricter, making the landfill option less reliable in the long run.

✅The solution:Treat excavated material as a raw material. By using the right technology, you can wash, sort, and recycle the material for use in new projects.

❌ 2. Failing to analyze the material before making a decision

The problem:Many people dispose of excavated material without knowing what it actually contains. This can lead to unnecessary costs or, in the worst case, legal problems if the material contains contaminants.

✅The solution:Conduct a material analysis early on. With a simple test, you can determine which fractions can be recycled directly on-site.

❌ 3. Mixing everything together in one pile

The problem:Many people think that excavated material is “just soil,” but it often contains plastic, metal, wood, and other waste. The more mixed the material is, the harder (and more expensive) it becomes to recycle.

✅The solution:Sort at the source! By sorting waste properly right at the workplace, you can reduce both transportation costs and landfill fees.

Would you like to learn more about smarter management of excavated material? Get in touch, and we’ll explain how we can help you increase recycling and reduce costs.

Here, we share concrete examples of how our solutions help customers reduce their environmental impact and lower costs through smart recycling.

Effective methods for recycling various wood materials

Bark and wood chips

Bark, branches, and tree tops (BTB) may contain contaminants such as stones, plastic, and sand, which affect the quality of the final product. With Norditek’s solutions, these contaminants can be effectively separated, resulting in clean fractions of optimal sizes.

Results:

• Production of high-quality biofuels for energy generation
• Optimized fuel quality for reduced emissions and higher efficiency

recycled wood

Recycled wood may contain plastic and metal, which must be separated so that the wood fraction can be recycled effectively. With the right combination of magnetic technology and air classifiers, we ensure that the wood is clean and ready for further recycling.

Results:

• Recycling wood into new products
• Energy recovery with minimal environmental impact

Biochar

The fraction is reduced to the correct size, and with inorganic material removed, it provides optimal pre-treatment of the material for biochar production. Norditek uses a combination of two machines to efficiently recycle coarse park and garden waste in the production of biochar: a star screen and windshifter. The method consists of two steps: density separation using air (windshifter) and size separation using a screen (star screen).

Results:

• High energy content
• Low ash content

Fuel pretreatment

Fuels containing plastic, metal, and moisture can reduce the efficiency of incineration plants. Through separation solutions, we can improve fuel quality and optimize energy recovery.

Results:

• Higher energy yield
• Reduced emissions and operational disruptions

Norditek's core methodology for high-quality recycling

To ensure optimal results and maximum flexibility, we follow a structured approach:

1. Material Analysis– We conduct material tests in a laboratory setting to analyze contaminants and fractions.
2. Proposed Solution– We design equipment and processes based on analysis results to maximize recovery value.
3. Full-scale testing– We conduct test runs, refine processes, and compile a results report to inform decision-making.
4. Reduced investment risk– We offer flexible financing options: rent, lease, or buy, tailored to the project’s needs.

Recycling of the Future – Efficient, Sustainable, and Profitable

By using innovative separation and recycling technologies, we create profitable and sustainable solutions for material owners and recycling companies. Would you like to learn more about how we can help you optimize your recycling operations? Contact us today!

Ensuring quality in the recycling process is one of the most important keys to long-term profitability. For companies and municipalities that handle large volumes of materials, it is crucial that every step of the process runs seamlessly—from material handling to recycling. With the right solutions and a systematic approach, operations can become not only more efficient but also more sustainable. Here are five ways to build a solid foundation for quality in the process and thereby maximize profitability.

The foundation for the right solution starts with understanding the material. All materials have different properties and require specific solutions to be processed effectively. By analyzing material samples, we not only gain a clear picture of the challenges involved but also the opportunity to identify the optimal machines and processes. At Norditek, we offer the opportunity to test the material in our own facilities and create solutions tailored to the customer’s needs. This ensures that every machine and every process works as intended right from the start.

The next step involves gaining a deep understanding of the customer’s specific circumstances. A needs analysis isn’t just a way to create a solution—it’s a way to create real value. By working with the customer to analyze materials, contaminants, volumes, flows, and potential applications, we can design solutions that meet both today’s needs and tomorrow’s requirements. Asking the right questions from the start and taking a holistic approach is often the difference between a solution that works and one that truly makes a difference.

Flexibility and scalability are other key components of an efficient process. The materials handled in recycling can vary greatly, and the client’s needs change over time. That is why our machines and systems are designed to be adaptable and scalable up or down depending on the situation. This flexibility allows customers to handle new materials or changing volumes without having to invest in entirely new equipment. It is a security that provides both short-term efficiency and long-term profitability.

To maximize the outcome of the process, the workflow must also be optimized. Every step in the production chain affects the next, and an inefficient part can quickly lead to bottlenecks or high costs. That is why we work to plan and optimize the workflow from start to finish. By ensuring that machines are properly positioned and that the flow between different steps functions optimally, we can minimize energy consumption, material waste, and downtime—factors that have a significant impact on profitability.

Ultimately, quality is about never stopping the pursuit of improvement. By monitoring production, we can identify areas with potential for improvement. Production measurement and continuous monitoring are fast becoming a central part of recycling and a priority area for Norditek moving forward. With the right tools and support, customers can track their progress and ensure they meet their goals, both in terms of efficiency and recycling rates.

Building quality into the process is not a one-time effort, but an ongoing strategy to optimize, improve, and future-proof the business. At Norditek, we are convinced that the right machine solutions, combined with a deep understanding of the customer’s needs, are what make a real difference. Would you like to learn more about how we can help you build a process that both increases profitability and contributes to a more sustainable future? Contact us today.

The methods used are not only environmentally friendly but also help to maximize recycling and reuse of resources. With machines like windshifter and air suction, separately or in combination, we can extract completely clean fractions of soil.

1. separation with windshifter

A windshifter is a machine that uses air currents to separate materials based on weight, size and aerodynamic properties. This machine is particularly effective at separating lighter plastics from heavier organic material.

- How it works:

The material is fed into a rotating screen where air currents blow away the light plastic while the heavier soil and compost fall down.

- Advantages:

- Efficient separation of larger plastic parts.

- Low energy consumption compared to other methods.

- Robust technology that handles large volumes quickly.

- Areas of use:

the wind shifter is ideal for pre-processing materials at recycling facilities and for projects that handle large volumes of mixed waste.

2. Separation by air suction

Air suction is a more precise method of separating plastic from organic matter. This technique is particularly useful for removing smaller plastic fragments that are otherwise difficult to remove.

- How it works:

For example, material transported on a conveyor belt encounters a powerful air suction that pulls the plastic away. The low density of the plastic allows it to be easily separated from the heavier organic parts.

- Advantages:

- High precision, especially for small plastic pieces.

- Can be combined with other technologies like windshifter for maximum efficiency.

- Gentle treatment of the material, preserving the quality of the final product.

- Areas of use:

Air suction is often used in post-processing steps to ensure that the final material is plastic-free and ready for reuse.

Environmentally friendly solutions

These technologies help create clean end products that can be reused as soil conditioner or compost, while recycling or recovering energy from plastics.

- "By combining dry screening and washing, we get a solution that increases capacity and water efficiency. The result is a circular sand and stone product that can be reused in new infrastructure projects," says Daniel Carlberg, CEO of Norditek.

The new technology is scalable and cost-effective, making it suitable for implementation in more regions. The dry stage separates large rock and clay before washing, increasing capacity and reducing unnecessary water use - the clay does not need to be washed. In the next stage, all iron is removed before washing begins. The washing process itself removes the remaining silt, clay and impurities such as textiles, wood and plastics, leaving a final product of clean sand and stone completely free of impurities. The wash water is purified by sedimentation in a basin and then returned to the process, allowing up to 90% of the water to be reused.

- By washing and reusing contaminated excavated material instead of landfilling it, we can reduce the pressure on our landfills. At the same time, we increase the supply of reused aggregates, which is important for a resource-efficient future," says Tommy Ohlsson, Regional Manager at Ragn-Sells.

Despite technological advances, competing with the price of virgin aggregates remains a challenge, which the industry needs to address to accelerate the transition to more circular materials management.

- "In order for cities like Gothenburg to reach their ambitious target of 50% recycled aggregates by 2030, both the supply of and demand for recycled materials must increase," concludes Tommy Ohlsson.
