Bioterra

Nowadays, impacts of buildings on the environment and on the health of inhabitants are priority issues. For many reasons, the demand for building products (bricks and plasters) made of materials such as clay and bio-based materials (vegetal fibres, granulates…) is increasing. Under certain conditions, a microbial development on such surfaces can be observed, which raises many questions about their use in buildings due to potential health hazards for inhabitants.The BIOTERRA ANR project (2014-2018) aims to identify and to characterize by cultural and metabarcoding approaches the microbial proliferation on bio-based earthen construction products, and to propose solution(s) to reduce or inhibit these proliferations, in order to ensure healthy and durable buildings.
