Summary of the project

Objective of the individual project

The recycling of material streams containing gypsum is currently mainly focussed on the recycling of plasterboard, particularly from the commercial sector, a relatively high-volume material stream. As gypsum waste is mostly generated during property renovation and demolition work, a high proportion of impurities in the form of adhesions (e.g. wallpaper) can be expected. Recycling gypsum can be produced by processing it in a gypsum recycling plant. However, depending on the input materials, the quality of the recycled gypsum is limited and it cannot be used for all purposes.

The "MobilGips" project aims to help utilise the raw material gypsum in a resource-saving and therefore responsible manner. It looks at two very interesting, low-pollutant gypsum material streams that have so far been ignored in terms of recycling - dental gypsum and small construction site waste from private individuals containing gypsum. These small quantities of gypsum waste are often not currently recycled and are therefore not available to the circular economy. As part of the project, collection and transport concepts for the recycling of gypsum waste from dental technology and private households (e.g. offcuts from plasterboard) are being developed and tested in field studies. The mobilisation of small quantities of gypsum waste should help to increase the availability of recyclable gypsum waste and thus increase the capacity utilisation of existing gypsum recycling plants.
