New momentum to support the sector of bio and geosourced materials in buildings

The objective is to develop the sectors of bio-based materials and to propose joint innovative service offers. This event was accompanied by a visit to the site of a school in Châtenay-Malabry which made it possible to observe the relevance of the use of bio-based materials in the building.

The building sector represents 43% of annual energy consumption and produces 23% of French greenhouse gas emissions. To reduce the sector's impact on the climate, the use of biobased materials is essential: they make it possible to conserve the carbon storage enabled by biomass and promote the economic development of the territories thanks to local production. For new construction, the new environmental regulations (RE2020) make it an important lever for decarbonising the sector. Bio-based materials can also be relevant for renovation.

To support and accelerate the development and use of biobased materials, the framework partnership agreement between Cerema and the company Biobuild Concept will mobilize complementary expertise and approaches to:

• develop tools, methods, services, services for the benefit of regions and players in the construction of biobased sectors,
• stimulate research, innovation and the promotion of results in the field of sustainable construction,
• carry out studies and expertise on sustainable construction.

This agreement is the culmination of an already fruitful collaboration: project to enhance the hygrometric performance of hemp concrete, standardization of aggregates for biobased concrete (NG2B), enhancement of the typha plant in West Africa (Tyccao project), earthen and biobased buildings in Mayotte and Guyana (TOMA).
