Slovenian Institute of Hop Research and Brewi

This database compiles companies, research institutions, and other solution providers from across the world who can provide the technical expertise to help your city develop more sustainably. Oftentimes cities may wish to carry out sustainable projects, but lack specific knowledge or capacity. The listed solution providers have experience in supporting cities and regions to achieve their sustainability goals. Solution providers can add their solutions by clicking here. All submitted solutions are subject to approval.   (Please note: inclusion on the list does not denote endorsement from the IUC programme.)  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).
