GYPSUM RECYCLING

Gypsum is a natural product, has a low allergy potential and is therefore very popular for building materials. From a building biology perspective, this material can be processed into various building materials. Gypsum also has a special property. Gypsum-based building materials are used to regulate the indoor climate, as gypsum absorbs moisture and releases it again. This property is perfect for the fire protection of houses. Finally, gypsum as a building material is good for the environment and environmental protection due to its natural origin. The natural resource gypsum must be separated from other building materials such as paper, wood, gravel and rubble for reutilisation. But how much gypsum-based construction waste is produced each year and how is gypsum separated from mineral waste and recycled?

The construction boom in Germany is leaving its mark on the waste balance. Old houses and buildings are being demolished and new ones are being built. The statistically recorded quantity of gypsum-based building rubble alone amounts to approx. 600,000 tonnes per year in Germany today. Around 50 % of this consists of recyclable material. Current estimates already assume one million tonnes per year by 2030. Germany-wide landfills for building rubble are reaching the limits of their capacity for receiving waste. The waste often has to be transported across national borders by logistics companies. Reason enough for us to drive forward the recycling of recyclable material such as gypsum with our TRENNSO-TECHNIK^® processing plants .

Our processing plants for old plasterboard and other production waste from plasterboard production aim to separate foreign materials and the carrier material (paper / film / tiles / bricks). This ensures a high purity of the gypsum fraction for use and recycling in the cement plant.

Several separation stages are efficiently harmonised in the recycling process in order to guarantee customers the assured purity of the end product qualities.
