REuse and REcycling of CDW materials and structures in energy efficient pREfabricated elements for building REfurbishment and construction – RE4
The overall goal of the RE4-Project is to develop a fully prefabricated energy-efficient building made of components containing up to 65% by weight of Construction & Demolition Waste (CDW) -derived materials and structures.
This will involve the development of several intermediate but self-standing industrial results, like an innovative CDW sorting system based on automated robotics equipped with advanced sensors, a number of prefabricated building components (including connections) based on CDW-derived materials and structures, the related production processes and equipment. The building component to be developed will be suitable for both new construction and building refurbishment, while the materials flows will be managed by a new BIM-compatible ICT tool. The RE4-Project results will be produced in an industrial environment, considering their perspective issues for the market uptake. The technical activities will be supported by LCA and LCC analyses, certification and standardization procedures, demonstration activities, professional training, dissemination, commercialisation and exploitation strategies, business modelling and planning.

Impact of Research
CDW have increasingly serious impacts on environmental, social and economic realms. There is no coherent framework for utilization of these wastes which are disposed both legally and illegally. Large quantities of CDW waste cause harmful effects on the environment if they are not managed in proper manner. This harms the environment, contributes to the increase of energy consumption, and depletes finite landfills resources. New technologies and strategies established in the RE4 project aim at reusing and recycling of CDW waste materials and structures in energy efficient prefabricated elements for building refurbishment and new constructions. These new technologies are supposed to change the approach to managing the CDW in European countries.

Sustainable Development Goals
This project aims to address the following SDGs:
Goal 9 - Industry, Innovation and Infrastructure
This will be achieved by providing opportunity to generate an easily constructed and easily disassembled building.
Goal 11 - Sustainable Cities and Communities
Project fits well within the urban mining strategies for waste management and the 3R policy of circular economy.
Goal 12 - Responsible Consumption and Production
This will be accomplished by conservation of virgin material and instead use recycled aggregate as an added-value product.
Goal 13 - Climate Action
This goal will be reached by lowering the carbon footprint of new construction.
