Summary: With the increasing consumption of coffee beverages, a large amount of food waste-spent coffee grounds (SCG)-is generated. SCG is highly polluting due to the presence of caffeine, tannins, and polyphenols. However, it contains 15% oil on average, making it suitable for biodiesel production.

Summary: In this research, silk fiber dyeing using dye extracted from spent coffee grounds (SCGs) with different metallic and natural mordants was conducted. The color strength and parameters of the dyed silk fabric samples were evaluated, and wash and light fastness were also tested. The results showed that the metal mordants had higher color strength compared to the bio-mordants. Among the methods and mordants used, pre-mordanting with pinecone led to the highest color strength, while post-mordanting with pinecone provided the best wash and light fastness.

Summary: This study explored a cascade biorefinery approach to produce biodiesel, fermentable sugars, and biomethane from spent coffee grounds, rich in high-value compounds. Transesterification and glycerol pretreatment were used to achieve high product performance. However, the low content of easily degradable compounds led to the need to search for better alternatives to improve methane production.

Summary: This study evaluated the effectiveness of ethanol and isopropanol as solvents for oil extraction from spent coffee grounds. The partitioning of ethanol and SCGO can be described by the Langmuir equation, while the partitioning of isopropanol and SCGO showed a linear relationship. The temperature did not affect the partitioning when isopropanol was used as the solvent. Ethanol hydrate required more solvent for SCGO extraction, while isopropanol hydrate required less solvent. A solvent-to-feed ratio of at least five is needed when considering an extractor with five theoretical stages operating at 80 degrees Celsius.

Summary: One economical approach to harvesting mature microalgal biomass is through the attached growth system. This study found that spent coffee grounds can serve as a support material for Chlorella vulgaris sp. microalgae, enhancing the attached microalgal growth. Additionally, a specific photoperiod regime with a dark period cycle of 4 hours per day resulted in the maximum microalgal density, allowing the attached microalgae to strengthen their mixotrophic growth and accumulate a significant amount of lipid.

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.
