The r² research groups were able to rely on the support of specialist research services in the integration and transfer project. For example, the project sponsor required all the joint project groups to show their contribution to sustainability. The integration and transfer project helped them to do so with its work on the socio-economic and ecological assessment and a workshop.
The groups were also able to get advice on transferring the results into practice. Technology roadmaps were developed on this with all the project groups. Additionally, in order to promote their realization, product-service systems for greater resource efficiency and productivity were assessed in a workshop and a study.
