REuse and REcycling of CDW materials and structures in energy efficient pREfabricated elements for building REfurbishment and construction

Start date: 01.09.2016

Duration: 42 months

Coordinator: CETMA

Budget: 4.8 M€


The main purpose of project is to develop a RE4 prefabricated energy-efficient building concept that can be easily assembled and disassembled for future reuse, containing up to 65% in weight of recycled materials from CDW (ranging from 50% for the medium replacement of the mineral fraction, up to 65%). The reusable structures will range from 15-20% for existing buildings to 80-90% for the RE4 prefabricated building concept.

Construction and demolition waste (CDW) is one of the priority targets of European Commission, because of the large volume of generated waste and its high potential for re-use and recycling. Moreover, a negligible percentage of waste is destined to reuse mainly because the majority of the existing buildings was not designed for disassembly and reuse.

RE4 project aims to promote new technological solutions and strategies for the development of prefabricated elements with high degree of recycled materials and reused structures from demolished buildings. The main aim of the project is to develop energy efficient building produced from CDW, thus minimize environmental impacts in construction industry.

The building component will be suitable for both new construction and building refurbishment. The innovation is firstly focused on the development of new sorting technologies. Such first stage of the recycling process establishes the amount of recycled material and also the possibility to properly close the product chain maximizing the product value. Such fraction/material/structure from CDW will be studied and processed with 3 different technologies (casting, extrusion and moulding) and transformed in the new or adapted prefabricated components. The prefabricated component developed in the RE4 project will be finally assembled into a RE4 prefabricated energy-efficient building concept designed for an easy installation and dismantling.
