The report for the German Federal Environmental Foundation answers these questions and many more.
R concrete – resource-conserving concrete – the next generation of material
The research project’s intended impulse towards resource conservation in construction can only be implemented in building practice in the long term if the production of resource-conserving R concrete proves ecologically beneficial from both the point of view of the concrete manufacturer and the construction waste recycler. It will also require the appropriate mineral construction waste to be available in sufficient quantities for the raw materials required for this purpose.
The “energy transition” is closely linked to a “raw materials transition” because electrical energy has previously been generated primarily from fossil resources involving the release of CO2. These raw materials simultaneously form the basis of chemical production. Using a single-stage electrochemical process to convert CO2 directly back into a raw material with high added value, or into an energy source material, is the exact opposite of the combustion and other usage processes (CO2→ CO + ½ O2). The objective of the research cluster is to evaluate the electrolysis of CO2 to CO as regards selectivity, energy efficiency, and achievable current densities in an industrial value chain.

Brochure „Renewable Energy – Innovations for a Sustainable Energy Future”
Since 2001, ifeu has been compiling and updating the brochure “Renewable Energy”. It provides a comprehensive overview of technologies, ecology and economy as well as systematic questions of the use of renewable energy.
The guide published in 1997 was thoroughly revised in terms of content and structure as a result of the brisk demand from municipalities throughout the Federal Republic of Germany. It thereby was supplemented by current priorities and fields of action and contains numerous current practical examples which are intended to motivate imitation or own activities in municipal climate protection.
The beginning of a climate protection partnership between cities in the USA and Germany as well as in Japan and Germany is at the forefront of a research and development project that ifeu is conducting together with the European Climate Alliance on behalf of the German Federal Environment Agency (Umweltbundesamt).
