Abstract

Solid waste is usually seen as a problem. However, current policies and strategic consider that if properly managed, such waste can be a source of useful products for society, such as oils and fats, lignin, cellulose and hemicellulose, pigments, bioactive compounds (tannins, alkaloids, and flavonoids), among others. In addition to contributing to more sustainable and circular economies, these products also have high commercial value when compared to those obtained by waste treatment methods currently used. Thus, spent coffee grounds are a promising source of natural by-products such as food additives, pharmaceutical components, biosorbents, biofuels, and bioproducts.In this way, this project has as its general objective the inclusion of spent coffee grounds, one of the most common residues obtained in coffee shops and coffee processing industries, and which is currently discarded, as a lignocellulosic raw material, to produce compounds of the so-called green chemistry, that is, of environmentally sustainable production, and which are of commercial interest, enabling cascading valorization chain. Specifically, the extraction of bioactive compounds from spent coffee grounds will be investigated. It is thus expected to make a positive contribution to scientific and technological development, within a broad concept of sustainability (environmental and socioeconomic), allowing advances in the conceptual design of processes using lignocellulosic residues to produce bioproducts with high added value.
