With the increase in world population and economic activity, production of sewage sludge has grown, its management become an environmental problem. The most traditional method managing is to dispose it landfills on farmland. One way valorize use thermochemical conversion processes produce added-value products such as biochar, biofuels, renewable gases. However, due high moisture content, using pyrolysis gasification involves multiple pre-treatment material drying. Hydrothermal usually require pressures, which pose many challenges their application a large scale. In this work, advantages disadvantages different existing for recovery were analyzed, well resulting industrial challenges. A SWOT analysis was carried out assess terms technical feasibility, viability, broader market considerations.

Abstract The potential application of the hydrothermal liquefaction process on catering wastes, spent coffee grounds (SCG) and orange peels, towards reducing municipal wastes was examined in this study, targeting to production biofuel intermediates. study focused two main parameters, temperature (280–350 °C) residence time (5–60 min) while other parameters such as biomass/solvent ratio applied extractant were selected according literature. results indicated that are a more promising feedstock, rendering higher bio-crude oil yield than peels (34 wt% 22 respectively). optimal conditions for each feedstock varied due their different structural properties, which not only affected products’ yields but also quality. To better understand distribution degradation products part reaction’s pathway, gas product analyzed via GC-FID, aqueous phase studied HPLC analysis. Finally, subjected elemental, thermogravimetric, GC-MS analysis determine its quality potential, based derived from showed peel–derived is lower value. According study’s findings, can be utilized fuel substitute after being upgraded hydrotreatment enabling heteroatoms removal enhancing properties. Graphical abstract
