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

The 2nd international conference on Circularity in the Built Environment (CiBEn) aims at becoming a major point of contact between researchers, engineers and practitioners in the area of green and sustainable construction. These topics call for a multi-disciplinary approach involving various research fields and expertise.

To this extent, CiBEn intends to provide all participating actors and stakeholders with the opportunity to exchange their ideas and showcases in advance/innovative technologies and methodologies to implement circularity in the European and worldwide construction sector.
Eight main topics embracing all different aspects related to the theme of circularity in the built and environment, and sustainable construction materials will be dealt with.

Among them, CDW Recycling Technologies, Sustainable Construction Materials, Circular Design & Management, Social Circular Economy, Standard Policy and Legislation, to mention a few.

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 primary and secondary construction materials in the context of circular economy and to facilitate the transition of the construction sector to fully circular economy model.
