HTC has prompted the production of hydrochar and has improved the dewatering of several kinds of biomass resources. Hydrothermal carbonization (HTC) is one of the thermo-chemical treatment methods that are currently being used to convert organic materials and to improve their dewatering and upgrade their properties so that they can be used as cost effective and environment-friendly alternative fuels. The dewatering of the byproduct has to be improved to solve the aforementioned problem to make a useful alternative energy source. The direct conventional thermal treatment methods, such as drying and combustion of byproduct need the high energy cost. It has serious problems, as a high moisture content and a poor dewaterability. The digested byproduct of SS-AD can be used as a fertilizer or as solid fuel. The result reported that SS-AD achieved a maximum methane yield of approximately 200 L/kg-volatile solids (VS) for the digestion of biomass containing 22% TS. Consequently, SS-AD has the following advantage: a higher organic loading rate, a smaller reactor volume, a lower energy demand for heating, higher volumetric methane productivity, and less wastewater generation. It can operate a high solid content feedstock, as higher than 15% of total solids (TS). SS-AD is used in more than 60% of the existing anaerobic digesters in Europe. Keywords: Hydrochar production, Hydrothermal carbonization, Organic waste, Renewable solid fuel, Solid-state anaerobic digestionĪmong the different biological treatment modalities, solid-state anaerobic digestion (SS-AD) has helped promote the development and application for biogas production from biomass. As a result, the hydrothermal carbonization process can be said to be an advantageous technology in terms of improving the properties of organic waste as a solid-recovered fuel product. Thermogravimatric analysis provided the changed combustion characteristics due to the improvement of the fuel properties. Therefore, after the hydrothermal carbonization, the H/C and O/C atomic ratios decreased through the chemical conversion. Hydrothermal carbonization increased the calorific value through the reduction of the hydrogen and oxygen contents of the solid fuel, in addition to its drying performance. The effects of hydrothermal carbonization were evaluated by varying the reaction temperatures within the range of 180–240☌. Hydrothermal carbonization was investigated for conversion of the organic residue from the SS-AD of livestock waste to solid fuels. The organic residue from SS-AD has to be improved to address these problems and to make it a useful alternative energy source. However, the digested byproduct of SS-AD can be used as a fertilizer or as solid fuel, but it has serious problems: high moisture content and poor dewaterability. ![]() The solid-state anaerobic digestion (SS-AD) has promoted the development and application for biogas production from biomass which operate a high solid content feedstock, as higher than 15% of total solids. ![]()
