“…The addition of a catalyst (K 2 CO 3 ) could significantly improve the quality and calorific value of bio-oil [38,40,48]. The heating value of bio-oil was as high as 38.059 kJ/kg [68]. The quality of bio-oil was upgraded to bio-diesel through the distillation and esterification processes, indicating that bio-oil might become a substitute for fossil fuels in the future [119].…”

The amount of food waste is increasing with the development of society and the increase in population; the rough treatment of food waste could result in a serious environmental crisis and waste of resources. Hydrothermal treatment is a promising scheme to achieve the harmless treatment and utilization of food waste. Although there are many studies on the hydrothermal treatment of food waste, there is still a lack of systematic summary and comprehensive analysis of the relevant literature. In this review, we provide an in-depth analysis of the specific impact mechanisms of hydrothermal conditions on the gaseous, solid, and liquid products. Meanwhile, the hydrothermal conversion mechanisms of food waste components are systematically sorted out. The review also discusses the potential application areas for the derived products from the hydrothermal treatment of food waste. Finally, the main challenges and future research directions are proposed to improve the development of the hydrothermal treatment of food waste.

“…The possibility of using food wastes through thermal reduction methods is presented in the paper [6], the authors focused mainly on the process gas. Pyrolysis of food waste with respect to the production of bio-oil is the subject of the paper [7]. Microwave pyrolysis with catalysts is a feasible method to handle food waste [8].…”

Wastes are the most frequent "by-product" of human society. The Czech Republic still has a considerable room for energy reduction and material intensiveness of production in connection with the application of scientific and technical expertise in the context of innovation cycles. Pyrolysis waste treatment is a promising alternative to the production of renewable hydrogen as a clean fuel. It can also reduce the environmental burden and the amount of waste in the environment at the same time.This paper presents the laboratory pyrolysis experiments of peanuts crisps waste to the final temperature of 800 °C. After the pyrolysis process of the selected waste a mass balance of the resulting products, off-line analysis of the pyrolysis gas and evaluation of solid residue in terms of adsorption properties and energy production and liquid products were carried out. The highest concentration of measured hydrogen (66 vol. %) was analysed during the 4 th gas sampling at the temperature varying from 750 to 800 °C.
