A review on the recent trends in solar-biomass hybrid drying of agro and marine products in the context of sustainable development goals

Post-harvest losses remain a critical challenge in global food systems, pressing the need for efficient and sustainable drying technologies to ensure food preservation and food loss reduction. The primary objective of this review is to study solar hybrid drying (SHD) systems with respect to their performance, economic viability, and environmental impact. From recent advancements in the design configurations, modelling approaches, and case studies, the review work evaluates the scalability, economic feasibility, and climate resilience of SHD for food preservation. Particular attention was given to solar-biomass hybrid drying (SBHD) systems, which demonstrate a significant scope for future development. Scaling up SBHD systems can empower farmers, self-help groups, and allied organizations to produce value-added products and increase their income generation opportunities. Moreover, the main purpose of this review is to establish the linkage between drying technologies and Sustainable Development Goals (SDGs), highlighting their importance in promoting sustainable energy use, ensuring food security and climate adaptation. Further, the findings indicate that the 12 SDGs and 36 targets support drying technology, predominantly focusing on zero hunger (SDG 2), clean and affordable energy (SDG 7), and climate action (SDG 13). The outcomes of this review will benefit researchers in the field of drying technology, which will enable them to focus on renewable energy, such as solar and biomass. Further, this encourages researchers to work towards an environmentally friendly path for alleviating food insecurity and track progress toward achieving SDGs.
