Towards Zero Waste in Industrial Networks (ZeroWIN) is a five-year project running from 2009 to 2014, to develop effective strategies for waste prevention through industrial networks. These networks exchange byproducts, energy, water and materials in such a way that waste from one industry becomes raw material for another. The ZeroWIN project tests these networks through 10 industry case studies in the automotive, construction, electronics and photovoltaic industries. The project is funded by the European Commission under its 7th Research Framework Programme. UNU-IAS SCYCLE leads Work Package 8 of the ZeroWIN project, which aims to provide targeted policy recommendations supporting the development of industrial networks in practice. This includes a thorough policy analysis, a stakeholder consultation, and synthesizing the results from case studies. In particular the stakeholder consultation has shown that there still seems to be a general scepticism in industry regarding industrial networking and its underlying principle of exchanging byproducts, energy, water, materials and production waste. However, the first results from the case studies — which look at, for example, defining technical requirements for redesigning existing photovoltaic systems in Spain, and establishing a resource efficient construction network in the UK, Germany and Portugal — show that all case studies can achieve a reduction of at least 30% in greenhouse gas emissions and at least 70% overall re-use and recycling of waste through successfully engaging in an industrial network.
