An organization founded in India in 2013 by six university friends has won a 2023 Earthshot Prize for its work in creating a waste-free world – one of five categories in the Earthshot Prize family. It aims to transform the lives of millions of women farmers even as it works to create a waste-free food system.

S4S works directly with more than 1,000 farmer and farmer cooperatives under its solar powered dehydration initiative, supported by USAID, UKAID, Gates Foundation, and the Government of India. Some 300,000 women smallholder farmers supported by S4S have recorded 10-15% increases in their profits, while the 2,000 female entrepreneurs they partner with have seen incomes double or even triple.
