Waste is recyclable materials in the wrong place


Waste is recyclable material in the wrong place - this statement is the central basis of many activities in our work area. The focus is on the analysis and optimisation of systems within the municipal waste management sector.

The increasing scarcity or price increase of raw materials makes recycling and waste management in the area of municipal waste an important element within resource management. The collection and recycling of secondary raw materials are in the foreground. The systems required for this are becoming increasingly complex.

Existing systems must be checked and optimised with regard to efficiency, but also with regard to citizen friendliness. Among other things, it is necessary to determine the existing potentials and properties of the respective material flows.

Research fields:

  • Conceptual development and analysis of systems in recycling and waste management
  • Disposal systems in international waste management
  • Potential analysis of material flows
  • Analysis of material flows

Joint project: Micro-plastics in composts and fermentation products from biowaste recycling plants and their input into soils

- Capture, Evaluate, Avoid -

Microplastic particles, defined as plastic particles (MP) < 5 mm, are increasingly seen as a burden on the environment. The joint project considers the comparatively little researched environmental system of soil (input paths and their possible influence). So far, the possible contamination of the soil by FMD in composts or fermentation products from the recycling of organic material has hardly been recorded.

Subproject 6:

Through composting and fermentation experiments, the process conditions during the large-scale biological treatment of biowaste are simulated on a laboratory scale under controlled conditions. The aim is to investigate the influence of process control on the fragmentation of plastics and thus on the formation of microplastic particles.

Project duration:
2018 – 2021

Completed research projects

The aim of the project is to spatially record the residual material and waste biomass potentials in Baden-Württemberg. The GIS model to be developed will enable the identification of the main waste and residual biomass sources as well as the optimisation of biomass-based recycling systems within the framework of the entire bioeconomy.
