Can food waste be sorted from the residual waste and then reused as a biowaste resource?

The City of Copenhagen has partnered up with the companies Bioman ApS, Gemidan A/S, and Econet AS to test the possibility of sorting food waste from residual waste for the purpose of biogas production. This new study clarifies, that by using a size sorting method it is possible to separate food waste from the residual waste for biogas production.

Will the future of plastic sorting be based on digital watermarks?

AIM, the European Brands Association, and the Alliance to End Plastic Waste announced today a partnership to drive the next stage of progress for intelligent waste sorting within the Digital Watermarks Initiative HolyGrail 2.0. They will collaborate with the City of Copenhagen to commence the semi-industrial test phase of the pilot. With this milestone, developers move one step closer to precision identification and sorting of plastic packaging waste through digital watermarks, with the potential to revolutionise the sorting and recycling process of (plastic) packaging.
