Household waste

The purpose of the installation is separating hard plastics, foils, metal, paper and Wet Organic Fraction from household waste. Each step in the separation process is aimed to create multiple recyclable products to be reused as a raw material for further processing.

Basically, the subsequent separation system consists of a shredder, magnets, wind shifters, ballistic separators and Near Infrared (NIR) scanners. The smallest fraction (0-70mm) is the Wet Organic Fraction (WOF). It is possible to ferment the integral WOF fraction or to separate mono-streams such as glass, plastics, metals and stone through our WOF reprocessing plant. What remains is an organic fraction with a much higher gas yield.

The fragments larger than 70mm are passed through a separator, where the material is first separated into a 2D and a 3D stream. The 2D stream consists of foils, paper and textiles. The 3D stream include rigid materials, such as hard plastic and cartons.

From the 2D stream, paper and foils are separated using wind shifting. The paper and foil fragments are determined by means of NIR-scanners.

From the 3D stream, hard plastics are separated using NIR-scanners. Where necessary, this stream is run under the magnets and is further stripped of iron or non-ferrous metal and beverage cans. Plastic is separated into streams for PET, PP and PE by a NIR-scanner.

The separation plant can be customized, designed and implemented with a processing capacity of 10 tons / hour to 70 tons / hour.
