Solution Information

Solution Title

Waste transformation into novel product assortments for Packaging and Horticulture Sector

Solution Title (in English)


Circular economy, agricultural waste, packaging


Agroindustry, Europe


The goal of this project is to replace polypropylene (PP) twines used on the hop fields with a biotwine made of polylactic acid(PLA) which is produced from natural materials, and that can be degraded by composting into water, CO2and biomass.The use of PP twine leads to a non-trivial disposal process at the end of the growing season as hop plants and twine need to be separated in order for these waste streams to be handled according to established environmental regulations. By using a PLA twine for the support of the crops, the hop plant biomass after harvest can be used as main ingredient of composting together with the twine and as a natural fertiliser or material to produce biodegradable products(bio-composites, planting pots, and packaging trays).
