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.


30.01.2018 | RE4 project at BUDMA Fair in Poland

The RE4 project will be presented by FENIX TNT at BUDMA - INTERNATIONAL CONSTRUCTION AND ARCHITECTURE FAIR in Poznan, Poland. The fair will take place form 30th January to 2nd February 2018.

BUDMA is the largest construction industry trade fair in Poland and Central and Eastern Europe. The fair is dedicated to the four major groups of visitors: architects, traders, contractors, and developers. Each year, more than 800 exhibitors meets here over 45 000 professionals. Exhibitors exposure is complemented by a rich programme of events, debates, conferences and seminars regarding the latest trends and regulation industry held by the recognized industry authorities.

22.12.2017 | New publication: “Valorization of construction and demolition wastes: RE4 building solutions”

We are glad to share with you the scientific work provided by Diagnostics and Civil Engineering Area (authors Agnese Attanasio and Alessandro Largo) uploaded on the open access platform of ProScience


This work, entitled “Valorization of construction and demolition wastes: RE4 building solutions”, focuses on the main challenges of the RE4 Project, which aims at the valorization of construction and demolition wastes (CDW) to be used as raw materials for novel and sustainable building solutions.  The main goal of the project is to radically modify the conservative construction approach by promoting new technological solutions for the design and development of structural and non-structural pre-fabricated elements with high degree of recycled materials from CDW (e.g., concretes, bricks, tiles, fine fractions or lightweight materials e.g. plastic, wood) and reused structures from the partial or total demolition of buildings available in Europe. RE4 represents one of the main EU front-runner projects in the field of CDW valorization, reuse and recycling, whom results might pave the way towards a greener and more sustainable Construction industry in Europe that will be based totally on circular economy concept in the near future.
