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.
