Urban biorefineries for a circular bioeconomy

26th June (08:40 – 16:30)
Sala de Graus (Faculty of Arts, University of Girona)

The urban biorefinery concept came up to promote the recovery of energy and value resources contained in urban waste to be used as a raw and secondary materials to create new value chains. This Workshop deals with the last innovative developments on the reuse and re-cycling of urban waste into high added-value products for a sustainable the society. Urban waste includes Municipal Solid Waste, Green Waste, Wastewater, and Sewage Sludge. The Workshop aims to be a contact point between Scientific, Academia, Industry, and Administration to share, discuss, and promote initiatives over the last developments in European cities within the European Green Deal over the base of the Horizon 2030. The Workshop is promoted in the framework of the European Project H2020.JTI.BBI DEEP PURPLE and shows last advances in a dedicated Session, and over the general subject through two consecutive Open Sessions where the most relevant novelties will be presented and discussed in a Round Table with relevant representatives from Academia, Industry and Administration. The intended audience includes junior and senior researchers and technologists aiming to enlarge their knowledge on Urban Biorefineries.
