Abstract
Unlike other wastes from the agri-food industry (straw, corn, cob, stalks, seeds, husks) widely used in biorefineries as feedstock for the production of high-value products (chemicals, biofuels and bioenergy), eggshells, spent coffee grounds, and brown onion skins have not yet found a suitable place in sustainable production, but are mainly landfilled burdening the environment. This paper aims to point out the great potential of eggshells, spent coffee grounds, and brown onion skins as secondary raw materials in sustainable development, with minimal production of waste streams.
Keywords
