The European Interreg 2 Seas project on biobased construction Circular Biobased Construction Industry (CBCI) has been concluded with the publication of an online magazine discussing the results.

CBCI investigated how we can use raw materials in construction more efficiently, thereby reducing CO2 emissions. Not only in the construction phase, but throughout the entire life cycle of a building. For the transition to a circular economy, an integrated approach to circular and bio-based building has been developed, which forms the basis for the construction sector.

In the project. different studies were performed in order to learn more about biobased materials, for examples by prototype wall panel testing and Life Cycle Assessments (LCA’s). Bio-based insulating materials were also tested in order to find answers to questions concerning the longevity, performance, fire resistance, proneness to mould development and risks of moisture. At Emergis in Kloetinge (Zeeuws-Vlaanderen, Belgium), a new wing of a mental hospital was built as a circular living lab.


In co-creation with clients and parties from the construction industry, a number of tools have been developed within the CBCI project. These tools help construction teams to make an estimate of the economic added value of remountable construction at an early stage in a project. It helps clients to determine the value of flexibility in the construction and to make disassembly at the end of life easier. With this information, they can fine tune their plan and take its value into account in the design and investment decisions. Results of the project further include whitepapers about essentials, a procurement framework and an overview of laws & regulations, among others.

In the CBCI project, partners from the Netherlands, Belgium, France and the UK worked together for four years. The project was funded with almost €7 million by Interreg 2 Seas 2014-2020, funded in part from the European Regional Development Fund (ERDF).
