Construction and demolition waste is the largest waste stream in Europe. The research project Constructivate aims to develop solutions that can be applied in the construction industry in order to increase recycling of construction and demolition waste.
About 25–30 percent of the total waste generated in Europe every year comes from construction and demolition, and very little of it is recycled. Therefore, Constructivate – a research project financed by the Swedish Foundation for Strategic Environmental Research (Mistra) – has taken on the challenge to do something.
“There are several challenges related to the field of construction and demolition waste. For instance, when we demolish an old building, we know very little about the content of the materials and the building, so we’re not quite sure if we’re allowed to recycle the materials,” says Johan Felix, Director Materials Technology at Chalmers Industriteknik* and Project Coordinator for Constructivate.
Johan Felix points out that it is important to start to think about demolition even in the early stages of a project, when designing a building and when planning a construction project.
“We need to involve the complete value chain. We need to involve architects. We need to involve construction companies. Because how you manage the construction project is very influential on how much waste you generate.”
