Swiss recycling success for Terex Washing Systems

TWS wash recycling plant

TWS wash recycling plant opens new revenue stream for Geneva-based customer

TEREX Washing Systems (TWS) have completed the commissioning of a new wash recycling plant in Geneva, Switzerland, which has been specially designed to convert construction, demolition, and excavation wastes (CD&E) into two sands and three aggregate products for asphalt production.

The main objective of the bespoke TWS plant was to provide a ‘complete crushing, screening and washing solution’ specially developed to meet the customer’s specific output requirements.


With a throughput of 100 tonnes/h, the wash recycling plant comprises an FM 120 C-2G sand plant, an Aggrescrub 150 log-washer and a Terex MPS impact crusher.

This section of the wash plant washes, classifies and stockpiles aggregates whilst recovering two specifications of sand. Any oversized material fed into the system is directed towards the Terex MPS crusher where it is crushed down to a manageable size before being fed back into the washing system.

The TWS plant also incorporates a fully integrated water treatment plant, which consists of a deep cone thickener, a flocculant dosing unit and a filter press that ensures up to 95% of the water used in the washing process can be recirculated back into the system.

Johnston Patterson, TWS product and applications manager, commented: ‘We have provided a complete end-to-end wash recycling solution for the customer. Our ability to fully integrate washing, crushing and water treatment allows us to design and manufacture systems that perform to a higher standard. Everything is here, from feeder to filter press.’
