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

RE4 is a collaborative research project of 13 partner institutions from science and industry funded under the European Union’s Horizon 2020 research and innovation programme.

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.

RE4 elements & demo sites

As a part of the RE4 project, we have developed high-quality prefabricated elements icorporating up to 100% of CDW. Quality of these elements and their reusability is going to be tested at the RE4 demo sites in three different countries of EU, located in two different climatic zones (Spain, Italy and UK). The replication potential outside EU will be tested in Taiwan.

05.12.2019 | An amazing achievement!

We are really proud that we have placed among the three finalists of the ".EU Web Awards 2019" in the "Better world category." The winners were announced during the Web Awards gala on 20th November 2019 in Brussels, Belgium and representatives of the RE4 project were invited to attend.

We have really enjoyed the amazing gala. You can enjoy it yourself on the EU registry FB page because the whole ceremony was recorded! All of that would not be able without your breathtaking support. Thanks to all of you!
