European Green Deal strategy aims to cut the greenhouse gas (GHG) emissions to achieve climate neutrality by 2050. Buildings are a key leverage point to reduce GHG emissions, but the embodied emissions related with their construction remain often the hidden challenge of any ambitious policy. Considering that a complete material substitution of building elements that necessarily release GHG is not possible (e.g., concrete and steel for foundations), here called “climate-positive”, in this thesis a material GHG neutralization was explored with the use fast-growing biomass insulations.
This work, hence, proposes a methodology to design “climate-negative” insulation bio-based composites by leveraging their ability to temporarily store carbon dioxide (CO2) in the biomass and delay the emissions in the atmosphere. Moreover, to lower the impacts also in their construction phase, it investigates the creation of sustainable materials and production cycles by exploiting the mycelium growth as a binder. As a result of the theoretical preliminary research, the design methodology for “growing” climate-negative biocomposite is proposed and applied to 4 biomasses (rice straw, hemp shives, Posidonia Oceanica and bamboo fibers) within the European context, by analyzing both their technical and negative emissions’ potentials. Their specific design and bio-manufacturing methods are specified for each biomass since they play a major role for the final calculation of the GHG emissions (here called Net-GWP). This comprehensive approach can help designers in the materials choice phase of a project while suggesting to policymakers and companies the most promising solutions to achieve the decarbonization of the building and construction sector, but not only.
