In plastics recycling, the use of washing systems such as pre-wash systems, hot-wash systems or friction washers often results in wet rejects and fines that are unsuitable for further processing. This waste often contains considerable amounts of liquid, which increases both the weight and the disposal costs. With WEIMA dewatering presses, plastic waste can be dewatered efficiently, separating the liquids and reducing the volume of waste by up to 90 %.

In addition, returning liquids such as water, lubricants or coolants to the water cycle of the washing system enables the sustainable use of resources. This reduces treatment costs and contributes to a more environmentally friendly recycling process. The compact design of the presses makes them the ideal solution for companies that want to minimize their transport and disposal costs.
These drainage presses are currently particularly popular.

WEIMA presses for cost-effective disposal
Cost-effective disposal through volume reduction
When disposing of plastic waste, the volume and weight determine the costs. Dewatering and compaction by WEIMA presses can significantly reduce the weight of the waste. Every liter of liquid that is squeezed out of the plastic waste reduces disposal costs. This cost-effective solution offers recycling companies and waste recyclers enormous economic advantages and contributes to the sustainable processing of rejects and fines.

Optimizing the water cycle - increasing fluid recovery
Cleaning plastic flakes with washing systems requires a lot of water, which must be treated and monitored regularly. WEIMA presses make it possible to separate liquids adhering to rejects and fines and return them to the washing cycle in order to keep valuable water in the system for as long as possible. This helps to reduce water consumption and extends the life of the water in the recycling process. At the same time, the weight of the waste is reduced, which lowers disposal costs.
WEIMA cylinder presses – The robust alternative to screw presses
In contrast to classic screw presses, WEIMA dewatering presses use a hydraulic cylinder. This reduces wear and minimizes maintenance costs. WEIMA presses are the ideal solution for companies looking for a robust, low-maintenance technology to dewater plastic waste after the washing process. Thanks to their long service life and low maintenance costs, they are the most economical choice for recycling companies.

The WEIMA C.200 - Compact and powerful
The WEIMA C.200 offers a compact yet powerful solution for dewatering plastic waste. With its hydraulic cylinder, it reduces the volume and residual moisture of the waste, thereby lowering disposal costs. It is particularly suitable for small and medium-sized businesses looking for an efficient and economical dewatering solution.
Higher throughput with the Duo version
WEIMA offers the Duo version for larger quantities of rejects and fines produced in pre-wash systems, hot-wash systems or friction washers. Here, two presses are combined to maximize throughput and recover liquids even more efficiently. This significantly reduces disposal costs and increases the overall efficiency of the recycling process.
