Summary: The study proposes and demonstrates the use of sulfite pretreatment to efficiently produce medium chain fatty acids (MCFAs) through anaerobic fermentation of waste activated sludge (WAS). The pretreatment of WAS at a sulfite concentration of 100-500 mg S/L for 24 h significantly improves MCFAs production and selectivity, with the effect positively correlated with sulfite concentration. The findings suggest that sulfite pretreatment enhances MCFAs production and WAS degradation, while promoting solubilization, hydrolysis, and acidification processes.

Summary: This study reports a new strategy to improve short-chain fatty acids (SCFA) production from anaerobic fermentation of waste activated sludge (WAS) by cetyltrimethylammonium bromide (CTAB) intervention. CTAB increased the yield and quality of SCFAs, improved the disintegration of WAS and the biodegradability of released organics, and altered the microbial community to favor SCFA accumulation. Economic analysis showed that CTAB intervention had comparable or higher economic benefits than traditional pretreatment approaches for WAS anaerobic fermentation.

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.
