SUMMARY:

Assessing the social impact of small and medium-sized biorefinery projects is essential to understanding the relationship between society and these bioindustries. However, one of the main challenges is the application of methods that allow considering quantitative aspects such as cost minimization and qualitative aspects related to social, technological, psychological, cultural factors, among others, that condition the behavior of individuals who live in communities and will be impacted by intervention projects. In the light of the aforementioned discussion, this study aims to evaluate the social impacts of small and medium-sized biorefineries, based on the selection of technologies for bioactives through a Multicriteria Decision Making Analysis Support Model - MCDA (Multicriteria Decision Making Analysis), with a view to human development of the South Coast Territory of Bahia. In this sense, this work contributes to the theme by pointing out evidence on different technological routes that preserve or conserve the Atlantic Forest and, at the same time, establish positive relationships with society. From this premise, the following contributions were presented (i) evaluate methods and metrics that quantify the socioal impact of biorefineries, (ii) develop a socioeconomic analysis of cooperatives and family associations in the Território Litoral Sul da Bahia - TLS, (iii) carry out technological mapping of small family producers in the TLS, and (iv) quantify the potential of bioproducts extracted from the Atlantic Forest and applications to small and medium-sized biorefineries. The results point to the existence of a lack of research aimed at investigating the social aspects of small and medium-sized biorefineries, which use different technological routes for the production of multiproducts, in addition, the technologies Hydrodynamic Cavitation and Heterogeneous Catalysis are presented as those that can positively impact social issues in territories and consequently generate new business opportunities and healthy living. More specifically, Hydrodynamic Cavitation avoids the excessive use of toxic compounds, which is important to generate quality in the job, and to avoid injuries due to chemical intoxication, another important issue is that this technology is easy to operate, and can be applied in greater or lesser scale of production, therefore, more accessible to communities. Heterogeneous Catalysis, on the other hand, has a smaller carbon footprint when compared to other technologies, meaning a lower social cost, however it is more applied to large projects. It is concluded that the absence of an up-to-date and efficient national policy for the development of technologies, oriented towards the use of biomass, aimed at promoting positive social impacts, has caused the impoverishment of communities as well as a proliferation of work analogous to slavery in the different regions of the country. Therefore, the proposed model can be used by decision makers to simplify the process of evaluating technologies to be used for the bioconversion of raw materials into several high value-added products in small and medium-sized biorefineries, as well as being useful to support the implementation of strategies that favor the technological and human development of communities.
