The implementation of an Industrial Symbiosis model could reduce the emission of greenhouse gases

A study led by c5Lab researcher Francisco Capucha, in partnership with researchers from the Institute of Welding and Quality and the IN+ Center for Innovation, Technology and Policy Research, concludes that the implementation of an industrial symbiosis model in the European cement industry can reduce, by 6 to 12%, the emission of greenhouse gases. This reduction depends on the approach to biogenic carbon (non-fossil origin) since its use can substantially influence the results.
