Every harvest season, fields across the world brim with leftovers, straw, husks, peels, and stems. These materials are often seen as "waste", they hold immense potential. In India alone, farmers generate over 600 million tonnes of agricultural residues every year, much of which is either left to rot or burned in the open, causing severe air pollution. But what if this waste could become wealth? Enter the world of agricultural waste valorization- a key part of the circular economy movement that turns waste into valuable resources. Valorization means transforming agricultural by-products into useful, value-added materials such as biofuels, fertilizers, bioplastics, and animal feed. It's a scientific yet practical approach that ensures nothing in farming goes to waste, closing the loop between production and reuse. In simple terms, valorization gives a second life to farm residues, turning them from pollutants into products.
