Resource Recovery and Recycling
The recovery of valuable resources becomes increasingly important in a circular economy. In this area, we investigate both new technologies and the legal and economic framework conditions required for their implementation.
One key area is the recovery of phosphorus from sewage sludge for later use, e.g. as fertiliser in agriculture. In Switzerland this is legally required. Also in industry, the recovery of precious metals, rare earth metals and other recyclable materials from waste and wastewater streams can be both ecologically and economically advantageous with the aid of efficient processes. Construction waste, such as old asphalt for example, accumulates in large quantities. With our technical know- how and the assessment of environmental impacts and pollutant risks, we contribute to safe recycling.
