Recycling facility for electrical and electronic equipment

About the project

Due to increased consumption, the amount of waste material is also rising steadily. Immark is an expert in the recycling of electrical and electronic equipment. Thanks to its state-of-the-art facilities, Immark achieves a recycling rate of up to 95%. The facilities generate valuable raw materials through several process stages, which are then returned to the recycling cycle. In the first step, the old appliances are sorted, triaged, and decontaminated by hand. Then, in the mechanical pollutant removal process, the old appliances are carefully opened during pre-shredding so that any remaining pollutants can be removed in the subsequent sorting stations. The pollutant-free material is then further processed in the fine separation stage, where metals and non-metals are separated. This allows metal and plastic fractions to be returned to the material cycle in as pure a form as possible. Rey Technology was commissioned to plan, build, and program a central plant control system for a total of seven independently controllable plant modules at the recycling plant in Regensdorf. nbsp;The project also included a retrofit of the control system for an existing module. 

The primary goal was to modernize and centralize the control technology in order to enable more efficient and simplified operation of the recycling plant. By dividing the project into two phases, the conversion could be carried out during ongoing operations. This minimized production downtime and ensured seamless integration of the new technology.

The central control system now enables simpler and more efficient control of the entire recycling plant. Retrofitting the older module also ensures that all modules are technically up to date and interact smoothly with each other.
