## Summary

The paper titled "Pelletization Characteristics of the Hydrothermal Pretreated Rice Straw with Added Binders" explores the potential of pelletizing loose rice straw to produce renewable fuels. The main objective is to reduce energy consumption and improve product quality. Two different pretreatment methods are employed: hydrothermal treatment and the addition of economic additives such as rapeseed meal and waste engine oil. A biomass densification platform is used to pelletize the pretreated rice straw while testing energy consumption and pellet quality. Results show that hydrothermal pretreatment reduces energy consumption and enhances product quality. Waste engine oil proves more effective than rapeseed meal as an additive. The obtained pellet quality meets middle-grade coal standards, indicating comprehensive utilization of waste agricultural resources is possible. This research contributes valuable insights into improving the efficiency and sustainability of pelletizing rice straw for renewable fuel production.
