Summary: The study shows that alkaline pre-treatment of grease trap waste can improve the bioavailability of organic matter and facilitate its use as a co-substrate. Full-scale anaerobic co-digestion assays of pre-treated grease trap waste and sewage sludge did not show inhibitory or operational problems under experimental conditions. An economic assessment for a 160,000 population equivalent WWTP in a European scenario showed a relatively short payback period.

Summary: The presence of PVC microplastics at environmentally relevant levels does not affect methane production but reduces the toxicity of cadmium. When the concentration of PVC microplastics reaches 30 particles/g TS, methane production recovers to 89.7% in the presence of 5 mg Cd/g TS compared to the control. The adsorption of Cd by PVC microplastics is higher than that of sludge-substrate, reducing the bioavailability of Cd during anaerobic digestion.

Summary: The role of bacterial interaction is essential in controlling bacterial functions, but its understanding in microbial consortia remains incomplete. This study found that the anticancer agent fluorouracil (FU) inhibited methane production from sewage sludge under anaerobic conditions. The inhibitory effect of FU was observed on acetoclastic methanogens rather than hydrogenotrophic ones, and it was also found to influence the composition of bacterial populations.

Summary: Alkaline pre-fermentation was proposed as a method to enhance both methane production and PAM degradation of PAM-flocculated sewage sludge, improving the efficiency of anaerobic digestion. Microbial community analysis showed enrichment of syntrophic bacteria in the alkaline pre-fermenter and elevated levels of acetotrophic methanogen in the anaerobic digester, contributing to the success of this microbial based strategy.

Summary: Antibiotic accumulation in waste affects anaerobic digestion and decreases methane production. Copy numbers of the mcrA gene are unreliable indicators of methane yields. Methanogens belonging to the family Methanosarcinaceae are more prevalent than those belonging to the family Methanosaetaceae after long-term anaerobic digestion.

Summary: This study compared the effects of direct exposure to AgNPs or indirect exposure via sewage sludge contaminated with AgNPs on earthworms and soil microbial communities. Results showed that direct exposure to AgNPs led to a decrease in potential carbon respiration in the soil, while the addition of sewage sludge had a greater impact on soil microbial diversity. The formation of Ag sulfides in sewage sludge reduced the impact of AgNPs on earthworms and soil microorganisms compared to direct addition.

Summary: The study shows that consumer products containing silver nanoparticles can release silver into the environment through wastewater, leading to accumulation in sewage sludge which can then be spread on agricultural land. The transfer of silver from silver nanoparticles and sulfidized silver into plants and primary consumers was measured, with species-specific bioaccumulation observed. Sulfidized silver was found to be less available than silver from original silver nanoparticles, potentially impacting food webs through chronic exposure.

Summary: The study aimed to compare the effectiveness of different digestates in the aerobic stabilization process and evaluate the quality of compost. It was found that digestate from the co-digestion process had higher composting efficiency with higher temperature and organic matter loss ratio. All composts met the requirements for organic fertilizers except for Helminth eggs content in compost produced from digestate from the wastewater treatment plant. The research also demonstrated that the produced composts can be utilized in the phytoremediation process for degraded areas, with significant increase in fescue biomass observed.

Summary: Wastewater generation is a global issue and its treatment is crucial for public health and environmental protection. Oxygenic photogranules (OPGs) have emerged as a potential alternative to conventional activated sludge (AS) process due to their ability to produce oxygen and better physical properties. The formation of OPGs is influenced by factors such as light intensity, ammonium nitrogen concentration, and the presence of filamentous cyanobacteria, which create a self-sustainable system for denitrification, carbon removal, and oxygen production. This review article aims to provide an overview of the cultivation methods, formation mechanisms, influencing factors, and research progress of OPGs.

Summary: Anaerobic digestion is a well-known method for stabilizing organic materials, offering benefits such as greenhouse gas reduction, alternative energy production, and valuable digestate acquisition. However, for heterogeneous materials like manure, single-substrate digestion may not be efficient. Co-digestion studies are increasingly appearing to address this issue, allowing higher biogas production and simultaneous waste processing. The future effective application of anaerobic co-digestion depends on regulations, work regime, and access to raw materials, which are explored in this paper.

Summary: Due to the lack of domestic certified reference materials for coal on the Polish market, a new and innovative product tailored to its needs was attempted to be manufactured using hard coal acquired from Poland's coal mines. The developed manufacturing method enables production of matrix reference materials for the domestic solid fuel market and is directed at research laboratories conducting analyses of solid fuels. The research provides a base for planning the production of additional reference materials and designing manufacturing schemes for reference materials for solid fuels or waste related materials.
