Waste infrastructure
Railway macadam
our concept for infrastructure
Recycling of waste from roads, tunnels and railways
Today it is standard practice to sort waste into 2 fractions and separate inert material by sorting only by size. This means that, for example, fuel sent to heating plants contains a large proportion of stone, gravel, concrete, glass, etc. which ends up in the ash after combustion.
In our waste sorting concept, the waste is sorted into 3 fractions with a flipflow screen, of which 2 fractions are wind sifted. The wind sifters remove heavy material such as stone, gravel, concrete, glass, etc. and the magnets can pick out metal in the heavy fraction.

infrastructure projects
Examples of projects:
Shaft masses with stone, wood, plastic, metal, etc.
Shaft masses with stone, wood, plastic, metal, etc.
Benefit:
Clean aggregate, reduced virgin aggregate production and reduced landfill.
Clean aggregate, reduced virgin aggregate production and reduced landfill.
Processing:
- High value clean aggregate
- High value clean soil
- Metal is recycled and wood and plastics are energy recovered
