Residual Waste

Heat generation from thermal waste treatment poses special requirements to the vapour or hot-water generator. The design and construction of suitable boiler plants which comply with these stringent requirements is one of our core competences. We use various firing systems of different manufacturers.

Example: Thermal waste treatment plant of furnace line 2 in KVA Trimmis / Switzerland
