Energy efficiency of products

Appliances and installations consume energy when they are used: in the household, in the boiler room, but also in industry and commerce. EU eco-design and energy efficiency labels are drivers for improving the energy efficiency of these appliances and systems. This research project supports the Federal Government in achieving demanding standards for new eco-design requirements and labelling and is also developing measures at national level to reduce the energy consumption of products.

Masonry rubble for resource-conserving construction

To what extent is masonry rubble reclaimed from demolished buildings suitable for use in resource-conserving building construction? Can this material known as type 2 aggregate be processed to make R concrete with properties that are comparable to conventional concrete made with primary aggregates, and is this ecologically viable? 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.

Kopernikus-Project Power-to-X

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.

Depending on the time at which they were filled, the domestic waste landfill sites used in Germany before 2005 are essentially a large reservoir of recyclable materials. The project showed that these sites represent a significant raw materials store, which makes landfill mining feasible under certain conditions. A guideline will be produced to facilitate an initial assessment of this option for different landfill sites.
