Summary: Recently, there has been growing interest in using organic or biodegradable wastes, including lignocellulosic wastes (LWs), as renewable energy sources. Anaerobic digestion (AD) of these wastes can mitigate environmental damage and produce biogas and bioenergy, which is particularly valuable in developing countries. However, there are several challenges to overcome, such as waste floating on top of reactors, high carbon-to-nitrogen ratio (CNR), complex structure of LWs, and poor degradability due to high lignin content. These challenges can be addressed through methods like mixing in reactors, reducing CNR, balancing inoculum-to-substrate ratio (ISR), and pretreatments. This study aims to review the literature on AD of LWs, identify existing challenges, and propose strategies to improve bioenergy production from this waste.

Summary: This study developed a co-fermentation strategy using waste cooking oil (WCO) and food waste for microbial lipid production. It was found that adjusting the pH values within a certain range could increase lipid production efficiency. The produced lipid could potentially be used for biodiesel production, leading to significant reductions in CO2 and SO2 emissions from global food waste.

Summary: In this study, a novel portable continuous bioreactor was designed and constructed to produce biogas at constant composition and volumetric rate. The performance of the continuous bioreactor was compared with batch reactors, and it showed excellent biogas purity and volumetric rate. The suitable hydraulic retention time and organic loading rate were determined, and the continuous reactor successfully converted biodegradable wastes to biogas.

Summary: This study evaluates the environmental efficiency of greenhouse tomato farms and examines the relationship between management type and environmental efficiency. The results show that the average environmental efficiency score for greenhouse farms is 0.86, with higher scores for professional farms and glass greenhouses. Variables such as education level, greenhouse size, net income, waste recycling investment, environmental knowledge, and green production practices have a positive impact on environmental efficiency.
