Summary: This study compares four common methods for treating food waste: incineration, anaerobic digestion, composting, and feed processing. The results show that anaerobic digestion is the best treatment option for minimizing carbon emissions, while composting has the highest carbon emissions. In terms of economic performance, feed processing is the best choice, while incineration results in high expenditure.

Summary: This study demonstrates the performance of ethanol fermentation pretreatment (EP) for food waste in achieving high-load anaerobic digestion operation using an anaerobic membrane bioreactor (AnMBR). By increasing the organic loading rate (OLR) and maintaining a low propionic acid accumulation, the methane content in biogas was significantly improved. Additionally, the study showed that primary methanogens were tolerant to ammonia inhibition, leading to improved buffering capacity at high load, and identified the abundance of hydrogenotrophic methanogens in AnMBR through 16S rRNA sequence analysis. The results suggest that the EP contributes to creating a virtuous cycle by maintaining a lower hydrogen partial pressure and achieving ultra-high load in the system.

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: The study identified refractory organics, referred to as melanoidins products (MPs), released from waste activated sludge (WAS) during thermal-alkaline pretreatment, which had high molecular weight and inhibited microbes. These MPs delayed the production of volatile fatty acids, reduced methane yield, and had a negative impact on anaerobic digestion after thermal-alkaline pretreatment.

Summary: The study evaluated the effect of solids retention time and lipid content on the efficiency of solid destruction and volatile fatty acids (VFA) yield in the bioconversion of food waste. Shorter retention time and higher lipid content reduced solid destruction efficiency but increased VFA yield. The introduction of degradable organics in waste oils and inhibition by long-chain fatty acids caused process instability at higher lipid content.

Summary: Biogas generation through anaerobic co-digestion of food waste and activated sludge is an excellent solution to address global challenges and meet increasing energy demands, while also providing a cleaner alternative for pollution and wastewater treatment. However, the efficiency and stability of this technology are hindered by irregularities in the substrate. Adjusting process parameters, optimizing substrate composition, and adding biochar as an additive can enhance the efficiency and outcome of the system.

Summary: The study found that tai chi has moderate effects for improving proactive balance and static steady-state balance, and small effects for improving dynamic steady-state balance and balance test batteries in adults over 60 years of age. The practice frequency could predict the effects of tai chi on static steady-state balance, and the 24-form simplified Yang style tai chi was identified as the most optimal program for improving balance in older adults.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.
