In 2020, Sweden generated 14.6 million tons of construction and demolition waste according to the Swedish Environmental Protection Agency, so the need for effective sorting methods is great.

Washing

For the recycling of excavated material and the recycling of aggregates, there are solutions with mobile washing plants. These plants can deal with muddy and sticky materials and obtain very small fractions. Mobile solutions make it possible to recycle excavated material also for more people as the investment is smaller.

Wind sifting

Excavated soil often contains organic material which can be effectively separated using wind sifters. Wind sifters make it possible to separate lighter materials from heavier ones, so in addition to excavated materials, construction waste containing concrete, wood, insulation, plastics, etc. can be advantageously sorted using wind sifters. Wind screening involves sorting according to the aerodynamic properties of the material.

Density separation

Density separation with a water bath separates materials by allowing materials to sink or float through a water flow. For example, in a construction waste, the water bath separates inert from wood as they have different buoyancy. At the same time, the water bath carries out a light wash. Density separation is relevant for many different types of materials such as industrial, construction and demolition waste, but also for waste sand and other materials. The water bath is developed and adapted to work together with a wind shifter which allows it to produce three clean fractions with high capacity.

Magnetic and non-magnetic

When demolishing old buildings, there is a lot of metal to be recycled. The metal is found in taps, pipes, brass handles and much more. Metal that is magnetic is relatively easy to recycle while non-magnetic metal is more difficult to separate from the waste. This is where Our technology comes in, with Our eddy current magnet you can separate and recycle all metal from old buildings. The technology can also be applied to waste that has already been burned in a heating plant.

Sifting

Screening is a basic method for sorting materials into different material sizes. Screening, or screen, divides the material into two or more size groups. In a construction waste facility, pre-crushing is often used to facilitate sorting. Crushing involves the breaking up of solid materials.

By developing and adding new modules, we at Norditek continue to create new opportunities in recycling. The flexibility of our facilities simply creates more opportunities to recycle construction waste.
