The Kassel Project - Use and recovery of biodegradable polymer packaging

Biodegradable and compostable packaging materials made from biodegradable polymers (BDP) were introduced into the market to reduce the amounts of conventional packaging materials. Material recovery by the municipal organic waste collection system was examined by analysis campaigns of the waste streams organic residues, packing wastes and MSW.

The processing of organic wastes mixed with biopolymeric packaging items has been tested in a commercial treatment facility. The safe use of the compost produced from these materials was demonstrated by regular compost analysis campaigns and in a full-scale agricultural application test. The collection via the municipal organic waste collection worked properly, and no increased amount of impurities was detected. The processing of BDP in composting facilities is possible though it may require some adaptation measures to provide optimal source separation. The use of produced composts for agricultural purposes has no negative effects on plant yields and soil.
