2nd International Conference on Circularity in the Built Environment (CiBEn)

Postponed to 24-26 November 2021
The 2nd International Conference on Circularity in the Built Environment (CiBEn) aims at becoming a major point of contact between researchers, engineers and practitioners on the area of construction and demolition waste (C&DW) processing and valorization.

Eight main topics embracing all different aspects related to the theme of circularity in the built environment and sustainable construction materials will be dealt with.
The EU28 generates around 350 Mt of C&DW, excluding excavation earths. The average recycling rate is of 50% for the stony fraction (concrete, stone and ceramics which are at present down-cycled) and of less than 30% for wood; 25% for plastics; 10% for gypsum and 6% for glass. Therefore there is a significant loss of potential valuable minerals and other materials all over Europe. The worldwide figures and trends provide an even worse scenario. That is why many initiatives are ongoing internationally to develop methodologies and technologies to turn this waste streams into resources for the benefit of the economy and the society at large.

CiBEn intends to provide researchers and industry experts with the opportunity to exchange their ideas and showcases in advanced/innovative technologies and methodologies to process and valorize C&DW in the context of circular economy. Topics of the Circularity in the Built Environment (CiBEn) Conference Include:
