Brief Analysis No. 26: Deconstruction in Building Construction – Current Practice and Potential for Resource Conservation

More than half of the total German waste volume is accounted for by construction and demolition waste from the building industry. This is reason enough to include the demolition and dismantling of buildings in the planning of a building from the very beginning, in order to reduce the volume of waste and conserve natural resources. The brief analysis shows the current practice of demolishing buildings and describes the potential for resource conservation in the construction industry.

Ecological and Economic Assessment of Resource Use - Cleaning Technologies in industrial Production

Cleanliness requirements and the associated residual dirt specifications have risen sharply in the area of industrial parts manufacturing in recent years. This is forcing companies to no longer view the cleaning process as a low-priority component of the production chain, but rather as a value-adding processing step. Here, resource efficiency potentials can be tapped, which reduce material and energy and at the same time lead to cost savings.

Ecological and economic Assessment of Resource Use: Additive Manufacturing Processes in industrial Production

Additive processes as a key technology of digitisation are considered to be faster and more cost-effective. Among other things, because less scrap is produced and less waste is generated during manufacturing. Using a specific case study, the study compares the resource consumption of an additive manufacturing process with a conventional manufacturing process.

Ecological and economic Assessment of Resource Use: Efficient electric motors in industrial production

Electric motors and motor systems play a significant role in energy efficiency. They account for approx. 40 % of worldwide energy consumption and could contribute to a doubling of the electricity consumption by 2030 if no further saving measures are taken. Choosing a high energy efficiency class is not enough to reduce losses and consumption since the power consumption differs greatly in the usually dominating use phase in the end customer’s application (varying load profiles, speeds etc.). The associated ecological and economic effects accordingly depend on several boundary conditions.

Ecological and economical Assessment of Resource Use: Stationary Energy Storage Systems in industrial Production

Stationary energy storage systems are a necessary component of a future power supply system with high shares of renewable energies. Used in decentralized industrial applications, they help to increase resource efficiency while minimizing the costs of power supply. Storage solutions for the short to medium-term storage of electrical energy are therefore seen as a contribution to the success of the energy transition being driven forward in Germany.
