Food waste is a major problem, and it is estimated that up to 40% of the world’s food is lost or wasted. This waste has a negative impact on the environment and the global food crisis. Improper post-harvest processing is a major cause of food loss, and it disproportionately affects low-income countries. The article discusses the use of renewable energy-based sustainable food drying technology as a way to reduce food waste. This technology uses heat pumps, thermal energy storage (TES), and solar energy to dry food, which can help to reduce energy consumption and improve the quality of the dried food. The article also discusses the importance of government policy in supporting the implementation of this technology. Overall, renewable energy-based sustainable food drying technology is a promising way to reduce food waste and improve food security.
