RCG gets gypsum moving

On 1 January 2026, a nationwide landfill ban will come into force in Austria. The aim is to promote gypsum recycling and establish a functioning circular system for this valuable building material – enabling its reuse in the building materials industry as a raw material for plasterboard production.

RCG: Logistics partner in the gypsum cycle 

To enable this cycle, PORR, Saint-Gobain and Saubermacher have founded the company GzG Gipsrecycling GmbH (GzG for short). The site in Stockerau was officially opened at the end of October 2025 – marking the official start of high-quality recycling of gypsum waste from the construction industry. GzG feeds the recycled gypsum (RC gypsum) back into the production of plasterboard. 

Gypsum waste has been processed at the recycling plant in Stockerau since mid-2025. After processing, RCG transports the RC gypsum in single wagons to the Saint-Gobain Austria plant in Bad Aussee. There, the recycled gypsum is used alongside natural gypsum from mining to produce new plasterboards – significantly conserving natural resources. 

Gypsum remains gypsum: sustainable transport for a sustainable material 

Gypsum is a building material with unique properties: it can be recycled endlessly. This means that new plasterboard can be produced from RC gypsum – in line with the motto “turn old into new”. Thanks to the combination of recycling technology and climate-friendly logistics, GzG and RCG are setting a new ecological standard in construction waste recycling. This is because the building material is not only recycled – RCG also ensures its return to plasterboard production via sustainable rail transport.
