not consider actors involved in wars, nor depend on petrol and is zero waste and land grabbing free. Creation of bamboo giant forests by means of the agricultural societies belonging to the group of the start-up. The latter provides several services such as the cultivation in Italy of the giant bamboo, the compensation of CO 2 , the opportunity to improve the balance of the Environmental, Social and Governance performances (ESG) and circular economy projects related to the use of bamboo in bio-plastic and bioconstruction industries. The products consist of paints, tonachini, lime based marmorini colored only with spontaneous plants and/or agricultural residues of the local territory, selected and processed, to be used mainly in the green building sector but in some cases in other sectors whenever they require innovative coloring materials with low environmental impact beyond those for the large-scale production. The products are obtained thanks to the recovery of material that should be otherwise eliminated with a disposal cost for farmers, strengthening a low environmental impact supply chain, based on the reduction of waste and high eco-compatibility from production to application, to disposal of residues, care for the health of the workers and local communities.

3.2 Analysis of the environmental impacts of some building products: bio-based and conventional Tables 2-4, shows the results from the literature review evaluating studies assessing the environmental impacts of conventional and bio-based construction/building products. These environmental data will be useful for performing a future LCA evaluating the impacts of materials and products of the selected CSUs. Table 2 presents the results of the study by Ghisellini et al. (2021), who compared the Cumulative Energy Demand ( CED) impacts of conventional, recycled and green concretes. The study highlights that the conventional concrete made of natural aggregates has the highest energy costs (1963.67 MJ) compared to concrete from recycled aggregates (1401.02 MJ) and green concretes (1301.50 MJ, 1171,78 MJ and 1042.07 MJ) depending on the fraction of allocation of the energy costs to hemp by products (30%, 20% and 10%).
