Catalyzing rural prosperity through modular and scalable biorefinery platforms: A technological and entrepreneurial review

The growing appreciation of decentralized uses for agricultural biomass has created an ever-increasing recognition of rural bioeconomy development potential. This review paper evaluates modular and scalable biorefinery systems compared to more traditional, centralized biorefinery businesses. Newer forms of rural biorefinery deployment will be especially beneficial for regions with both a diversity of biomass types/resources and inadequate infrastructure accessibility. While the individual components of the review are not completely new, the comprehensive evaluation of the combined technology-related, business and governance-related aspects to rural biorefinery deployment is. The evaluation includes examination of advancements in technology (i.e., portable processing facilities [containerized], modular reactors, digital controls) as well as potential business models that relate to biorefinery establishment/deployment in rural areas (i.e., Farmer Producer Organizations/FPOs; Cooperatives; Franchise operations; public-private panchayat partnerships, etc.). This review also proposes a scaled list of biorefinery typologies that range from micro-units at the village-level to regional biorefinery hubs, and discusses various funding options, typical implementation challenges, and potential new technologies and approaches (i.e., AI-enabled process optimization; renewable energy utilization) that can contribute toward greater efficiency in rural biorefinery and governance-based businesses. By making connections between engineering-related biorefinery design with entrepreneurship and governance, this review provides a thorough guide for distributing biorefinery operating systems that establish and reinforce effectiveness in using resources, generate locally-created value, support energy independence, and build circular bioeconomy systems. Overall, the ability for modular biorefineries to convert agricultural waste into economically beneficial opportunities for rural communities increases the likelihood of improving both income and environmentally sustainable livelihoods for rural residents.
