MycelPack

Development of compostable molded packaging parts made from renewable raw materials and an associated manufacturing process

Aim

The aim of the research project was to develop compostable primary packaging for the transportation of mushrooms, fruit and vegetables. The aim was to use residual materials from the cultivation and harvesting of edible mushrooms as a raw material. This involves the wood-fiber-based growing substrate that has grown through the mushroom mycelium. With the help of a suitable new technology, this is processed close to the producer and cost-effectively into molded packaging. The focus is on additive-free processing by utilizing the natural ingredients of the raw material for the manufacturing process and reducing the use of water as much as possible in order to make the process energy-efficient.

In the sub-project of TU Dresden (Chair of Wood Technology and Fiber Materials Technology), strategies for processing the residual materials, such as shredding and grinding, drying and fleece and mat formation, were investigated. In addition, a starch-based binder and bio-based hydrophobizing agents were applied to improve moisture resistance. The prepared raw materials were processed into test panels and their mechanical and hydrophobic properties were examined.
