Sustainability on all levels

Sustainability is very important to CASEA and we implement it at all levels – from the supply of raw materials and logistics to production and recycling. Our regional focus with quarries in different parts of Germany also contributes to sustainability, because it avoids unnecessary climate-damaging transport routes. We also have a social commitment, as well as our ecological one. We secure long-term jobs at our locations and support a large number of associations and events such as the Harztorlauf run.

Raw material extraction with a sense of responsibility

Three of our four production sites have their own quarries. Even before extraction begins, land is acquired for compensation measures and planted, for example, with trees or developed as orchards. The renaturation begins successively during the mining process and is adapted to the morphology of the terrain so that, at the end, an upgraded state can be returned to nature. Numerous biotopes in former gypsum quarries, which contribute significantly to the preservation of biodiversity, already show that this is possible.

Protection of natural resources

In order to conserve the natural resources gypsum and anhydrite as much as possible, in addition to naturally occurring anhydrite and gypsum stone, a large number of other raw materials are used for the production of gypsum products. For example, our sites have been using secondary raw materials such as FGD and chemical gypsum as well as synthetic anhydrite for many years. FGD gypsum is produced as a by-product in flue gas desulphurisation systems when coal is converted into electricity. Chemical gypsum come from the production of citric acid and lactic acid. Synthetic anhydrite is a by-product of hydrofluoric acid production.

Pioneers in gypsum recycling

Another very important secondary raw material for us is gypsum from the recycling of gypsum-containing construction waste. As a sustainably managed company and as part of the REMONDIS group, we already use recycled gypsum and are trying to establish this sustainably too. Two of the three gypsum recycling plants in Germany are currently operated by the REMONDIS group at sites in Großpösna and Zweibrücken.

Used moulding plaster as well as reconditioned recycled gypsum from old plasterboard are used in our factories as raw material for new plaster products

Commitment in conjunction with universities

Not only do we carry out extensive gypsum recycling, but we are also campaigning for more gypsum products to be returned to the production cycle and for recycled gypsum to gain the necessary market acceptance. For this purpose, we have launched the WIR! Project “Gypsum recycling as an opportunity for the southern Harz” together with the Nordhausen University of Applied Sciences and the Bauhaus-University Weimar. The aim of the project funded by the Federal Ministry of Education and Research (BMBF) is to initiate change in a structurally weak region by promoting innovations. In this specific project, the southern Harz region is to be established as a centre for gypsum recycling in the long term.
