BL1-4 AROUND

The AROUND project aims to research the production of new types of diamines from renewable raw materials for use in production technology. Diamines are an important starting material for the production of isocyanates, for example, which are important raw materials for the production of polyurethanes that are used as foams, including as high-quality insulating materials.

Diamines are also used in the polyurethane and epoxy industries as raw materials for the production of high-quality coatings and adhesives. With the new chemical structure of the molecules, new and/or improved properties are expected in both areas of application.

Based on preliminary work by Covestro Deutschland AG and others, two potential routes for industrial implementation are being investigated as part of AROUND: Chemical catalysis and enzymatic catalysis. Both processes will be further developed and analysed in the first phase of the project. Based on these results, an initial conceptual process design is to be created, which will provide insights with regard to subsequent piloting. The usability of the diamines obtained in this way for the production of polymers will be analysed and any necessary modifications identified.

The accompanying LCA, Life Cycle Analysis, will record the actual and holistic CO2 savings potential at an early stage, thus creating a solid and comprehensive evaluation basis for the project results. The utilisation of diamines in the epoxy industry will also be evaluated, which would be associated with the creation of a new market.

On completion of the project, in addition to the extensive knowledge gained, which can be used for further work in the emerging Bio4MatPro Competence Centre, a proof of concept will also be available, which will enable both the feasibility and cost-effectiveness of the solution approaches to be considered and a reliable assessment of the CO2 saving potential to be made.
