Task 36 Material and Energy Valorisation of Waste in a Circular Economy (previously known as Integrating Energy Recovery into Solid Waste Management Systems) is an international working group which seeks to raise public awareness of sustainable energy generation from biomass residues and waste fractions including municipal solid waste (MSW) as well as to increase technical information dissemination. As outlined in the 3-year work programme, Task 36 seeks to understand what role energy from waste and material recycling can have in a circular economy and identify technical and non-technical barriers and opportunities needed to achieve this vision.
