Summary: This paper applies an innovative optimization methodology to study the supply chain of biomethanol production in Sweden. The research considers the collection and transportation of biomass as well as the size of the biorefinery plant. The results show that the size of the biodiesel plants limits the collection of forestry residues. The study also finds that the low carbon intensity of Swedish electricity contributes to the low CO2 emissions of biomethanol.

Summary: China's agriculture, which feeds 20% of the global population, is a significant contributor to greenhouse gas emissions. To achieve carbon neutrality, the study proposes the utilization of sustainable biomass waste, such as crop residues, forest residues, livestock manure, food waste, and sewage sludge, for biochar production. The potential of biochar production from these waste resources in 2018 can offset the methane and nitrous oxide emissions from China's croplands. However, the distribution of biomass waste varies across regions, and differential policies and pyrolysis technologies are needed to maximize the climate benefit.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
