Conversión de residuos lignocelulósicos urbanos en fuente de bioenergía mediante carbonización hidrotérmica

Abstract

The hydrothermal carbonization process has attracted the attention of the academic and scientific community as an emerging and ecological technology for the transformation of urban lignocellulosic waste into a source of bioenergy in solid form (hydrochar),liquid, and gases. This review addresses understanding the properties and potential use of these wastes as a source of bioenergy. The physicochemical and energetic properties of these wastes are analyzed, as well as the operating parameters that influencetheir transformation. Furthermore, new perspectives are presented on future challenges related to the potential use of this waste and the carbonization process. The sustainable conversion of these urban wastes into a source of bioenergy will contribute toreducing dependence on fossil fuels, minimizing greenhouse gas emissions, ensuring efficient urban waste management, and developing a circular bioeconomy.
