Conclusions The preliminary results of this study show the sample of the selected CSUs resulting from the mapping of the construction industry in Italy. The data collected from the interviews to the selected CSUs regarded the characteristics of their activities and innovative bio-materials and products. The analysis of the literature highlights the superiority in terms of lower impacts of the analyzed bio-based construction materials and products compared to conventional ones. The evaluation of the products of the selected CSUs shows that there is the possibility of adopting a cleaner production in construction sector that is able to reduce the disposal in landfill or combustion of the local residues and valorize them in more cleaner supply chains. In that, these results evidences that there is a potential business in recovering bio-materials as well as there are no economic barriers that cannot be overcome thanks to the innovative processes and passion for developing a more sustainable entrepreneurship also useful to improve the local environment. Of course, only a limited set of biomaterials and products has been considered in the literature review useful to create an initial set of environmental data required to assess by means of LCA the biomaterials and products of the sample of the selected CSU. The results of the LCA will be presented in future research. Further research is needed to delve deeper into two aspects. The first is the adequate convergence of economic and environmental performance for cleaner production in the construction sector and in line with social impact, given that this sector is characterized by many specific factors at a local level and by the presence of a fabric of small and large businesses which are often closely interconnected by contractual relationships; the second is the role that the setting of an adequate regulatory system should have to support the development of more sustainable construction sectors as this can impact (as a barrier or as a driver) on more sustainable entrepreneurship. This regulatory system should be aligned with specific International, national and local needs and factors Acknowledgements The research presented in this study has received funding from the European Commission’s research programme Horizon 2020-SC5-2020-2 scheme, Grant Agreement 101003491 (Just Transition to the Circular Economy Project) and the Research Project of Relevant National Interest INSPIRE : Digital Innovation EcoSystem DeveloPment for the Circular Economy: the startups' perspective.
