bifa Umweltinstitut: Resource protection, substitution and digitalisation through foundry gas recycling

In the previous project, dust was analysed, classified and material streams were digitalised for four Bavarian foundries. The objective was to define recycling options for the dust so that it can be added back into the material cycle to achieve sustainability.

The intention of the new project is to incorporate foundry dust in secondary resources and thus reuse it. Working with GPS SIC Keßl GmbH u. Co. KG, recipes for pellets are to be optimised with regard to their composition, CO₂ balance and resource efficiency and scaled to the “Technikum” (technical centre) scale. It is also intended to optimise the material stream management. Waste materials from foundry processes can then be provided for reuse and valuable primary resources can be saved.

Closing recyclable material cycles in Bavaria

According to calculations, with the process, dust in the order of quantity of several hundred tonnes can be recycled. With the project, the precise mapping of the dust, its classification, digitalisation and laboratory tests started in ForCYCLE II will be transferred to the Technikum scale. Together with the Franken-Guss foundry, the intention is to develop systematic recipe variants for different pellets from the digitalised dust data.

The collaborative project is being funded by the Bavarian State Ministry of the Environment and Consumer Protection (Bayerischen Staatsministerium für Umwelt und Verbraucherschutz) and coordinated by the Bavarian Resource Efficiency Centre (Ressourceneffizienz-Zentrum Bayern, REZ) of the Bavarian State Environmental Agency (Landesamt für Umwelt).
