About
S4S Technologies equips smallholder women farmers in India with solar-powered conduction dryers and food processing tools, enabling them to preserve surplus crops on-site.
S4S connects farmers directly to commercial buyers, ensuring fair profits and creating nutrient-dense, preservative-free food products with a low carbon footprint. These farmers save resources and increase their income by 9–15%.
Project Focus
Shell Foundation is supporting S4S to help these women farmers strengthen their businesses with reduced losses and market linkages and establish others as micro-entrepreneurs able to run the dehydrators as standalone enterprises. S4S Technologies won the 2023 Earthshot Prize.
