ExpectedOutcome:
Project results are expected to contribute to all of the following expected outcomes:
- Better understanding of the properties of products using bio-based material(s) derived from secondary sources by the construction sector stakeholders;
- Roadmaps for the industrial scale production or re-use (beyond the established state-of-the art recycling and down-cycling) of at least four different types of products using secondary bio-based materials unlocking and demonstrating the full potential and benefits of the circular bio-based economy;
- Enhanced environmental performance of the construction products, including enhanced resource efficiency and potential long-term carbon removal.
Scope:
Although the NEB has been championing bio-based materials for the built environment, more research is needed on products that make use of secondary bio-based construction materials, such as from by-products or waste from other industries or processes, including bio-based composites and residues/by-products from agriculture or from fishing, aquaculture and agro-food industries, in line with the cascading principles[1]. Using such products in the construction sector will reduce reliance on primary resources, hence minimising the environmental impact associated with their extraction and processing.
Proposals should increase the potential of innovative bio-based products making use of materials from secondary sources for construction applications, thereby enhancing the circular bio-based economy in the construction sector, in line with the NEB values and the cascading principles. Project results will allow to inform the construction sector’s supply chain, including architects, developers and other construction sector stakeholders, about the availability, potential, and added-value of bio-based materials from secondary sources for new construction and renovation projects.
Proposals are expected to, for each secondary bio-based product covered:
- Assess its properties, benefits, design and construction possibilities and aesthetic[2]. This should cover at least the structural, thermal, acoustic, health-related and durability properties as well as the life cycle performance and environmental impact. This should also include the potential for deconstruction, re-use and recycling when buildings/public spaces undergo changes;
- Validate it in a relevant environment;
- Identify the sectors and applications where the chosen secondary bio-based material(s) could be embedded in construction processes and practices;
- Evaluate its economic scalability, including pathways for setting up efficient circular value chain to collect the secondary source.
- Contribute to the development of relevant European standards.
Cross-sectoral and cross-disciplinary collaboration is encouraged between profiles such as architects, artists, designers, engineers, biologists, urban planners, environmentalists, social scientists, and by extension the broader cultural and creative sector.
Actions are strongly recommended to collaborate with and build on the work of relevant research, including national or European funded research[3]. Actions are also encouraged to take into account and contribute with their results to future work in the field of regenerative design applied to architecture.
Projects shall share their intermediate and final results and findings with the 'New European Bauhaus hub for results and impacts' that will be established[4]. It will also cooperate, interact and take part in its activities when relevant to support the achievement of its objectives. Resources should be dedicated to engage with this Coordination and Support Action.
Specific Topic Conditions:
Activities are expected to achieve TRL5 by the end of the project – see General Annex B. Activities may start at any TRL.
