Sorting plants

Industrial waste

If the target is an efficient sorting, mixed construction and industrial waste or bulky waste have high requirements for the plant manufacturing.

A process combination of grinding, separation and conveying technology have to comply the demanding task to separate the material streams.

Downstream visual identifying systems divide the different recyclables fully-automated. On a high level of throughput economical output in combination with high purities can be realized. The manual follow-up control for the quality assurance takes place after the upstream mechanical treatment. Intermediate goods like parts of the fine and residual fraction or high caloric fraction provide the opportunity of different uses. All recyclables (pressed into baled or stored in containers) can be put on the market.

 

Light packaging

The charging of the material occurs according to the collection principle by bag openers or underfloor conveyors. The essential sorting consists of an combination of successive turned mechanical processes and manual control afterwards.

In the first step large pieces of cardboard, foil, non-packaging made of similar materials and large extraneous materials are removed in the pre-sorting step. Separation technology like drum sieve machines and multi fraction separators separate the input volume flow into various fractions.

In additional processing stages recyclables like ferrous and aluminium can be separated by using Fe- and NF-separators. For the light film fraction air separation systems are appointed.

Optical sorting systems with automatic discharge separate fractions like tetrapack, paper, films and different kinds of plastic like PET, HDPE, PS and PP.

The final quality control takes place as a manual control. The recyclables are baled and brought to the reprocessing.

 

Pasteboard, paper and cardboard

Even if the separate collection of pasteboard, paper and cardboard builds the base for a high recycling quote, only the right choice of technology can lead to an economical sorting plant. Main part here is a automatisation as far as possible.

Mechanical separation technology splits different material streams. Conveyor technology straightens out and isolates them, so that an optical identification system can guarantee a varietal separation in defined raw material sorts. In addition to the main product deinking, there are mixed paper and varietal brown and white cardboard.

Prior to the final bundling for the ongoing marketing, all qualities are controlled manually again.

 

Plastic bottles

In preceding sorting plants light materials are separated in that way that the material stream plastic bottles is already enriched on a high level with the target fractions PET-clear, PET-light blue, PET green and PET.

A combination of machinery for perforation and screening as well as conveying technology for equalization and isolation optimizes the presentation of the material streams for the optical separation systems.

NIR-separators with a combined material and colour identification guarantee a high sorting quality. The purity is achieved by a cascaded sorting chain of positive and negative sorting of the desired fractions. The optimisation of the profit can be realized by purification of the residual streams.

The target fractions are controlled manually afterwards in order to extract non-beverage-bottles and other parts of the same material
