The article discusses various research topics related to biomass and bioenergy, including using poplar biomass for renewable energy, promoting biomass energy in Bangladesh, and converting biomass compounds with additives in hot-compressed water. The researchers explore new materials and environmentally friendly uses of lignin, as well as the potential for increased heat production from aerobic thermophilic treatment of swine waste. They also investigate tar removal from biomass gasification processes and the feasibility of using chicken litter as a biomass source.
