ConWEEB Workshop presents innovative solutions for converting construction and demolition waste (CDW) into new prefabricated elements for better energy efficiency of buildings. The workshop is divided into 3 thematic sessions: selection of CDW for recycling; characterization of the materials obtained from processing the CDW; and presentation of the design of the new prefabricated solutions.

The workshop is organized by four EU H2020 Projects:

• InnoWEE – The basic idea is to embed the waste from building demolition (fragmented bricks, fragmented plaster or concrete, fragmented glasses, machined wood from windows frame or from wood beams after demolition etc.) in a geo-polymer matrix to produce prefabricated panels for different use. The main objective of InnoWEE is in fact the development of an optimized reuse of Construction and Demolition Waste (CDW) materials producing high add value prefabricated insulating and radiating panels to be used in energy efficient buildings.

• Green Instruct – The Green INSTRUCT project will develop a prefabricated modular structural building block that is superior to conventional precast reinforced concrete panels by virtue of its reduced weight, improved acoustic and thermal performance and multiple functionalities. The Green INSTRUCT block consists of over 70% of CDW in weight. More info at: 
• VEEP – The main objective is to eco-design, develop and demonstrate new cost-effective technological solutions that will lead to novel closed-loop circular approaches for C&DW recycling into novel multilayer precast concrete elements (for both new buildings and refurbishment) incorporating new concretes as well as superinsulation material produced by using at least 75% (by weight) of C&DW recycled materials.

• Re4 – The overall goal of the RE4-Project is to promote new technological solutions for the design and development of structural and non-structural pre-fabricated elements with high degree of recycled materials and reused structures from partial or total demolition of buildings. The developed technology will aim at energy efficient new construction and refurbishment, thus minimizing environmental impacts.
