Summary: The USA, China, and India are the top producers of municipal solid waste, with waste composition varying based on income levels. Municipal solid waste management options include recycling, incineration, waste-to-energy conversion, composting, or landfilling. Landfilling is a preferred method globally, with critical factors for sustainability including liners, soil cover thickness, leachate collection, and gas recovery facilities. Landfills act as ecological reactors undergoing various transformations, with bioreactor landfills emerging as a next-generation solution for efficient waste stabilization through controlled recirculation.

Summary: Effective waste management, including energy recovery, is not successful in many cities in India. This study evaluates the energy recovery potential and environmental impacts of different waste to energy options in Dhanbad city, India. By comparing six scenarios, it is found that mass incineration and landfilling have the highest energy recovery potential and environmental savings. The sensitivity analysis shows that the collection efficiency of landfill gas significantly affects global warming and photochemical ozone creation potential.

Summary: The systematic review of scientific LCA studies on waste to energy technologies showed that different WtE technologies can have varying impacts on different environmental impact categories. For instance, anaerobic digestion was found to minimize environmental consequences in most aspects when dealing with organic wastes, except for ecotoxicity and human toxicity categories. Additionally, the preference of incineration over landfilling for municipal solid waste treatment was generally agreed upon in the results. Sensitivity analysis revealed that assumptions in substitution of WtE products are the primary source of uncertainty.

Summary: An assessment of the inhalation health risks of waste to energy plants and landfills in the Bohai Rim region of northeast China was conducted. The study calculated the population-weighted hazard index (HI) and carcinogenic risk (CR) of incineration and landfill for each pollutant and target organ affected. The results showed that the health risks were below acceptable levels, with lower HI and CR values for both incineration and landfill. The non-carcinogenic risks mainly affected the respiratory and nervous systems, while the carcinogenic risks targeted the respiratory and digestive systems for incineration, and the hepatic and respiratory systems for landfill.

Summary: Municipal Solid Waste (MSW) is disposed of in an unorganized and disordered manner, leading to severe environmental consequences and health hazards. Landfills in India require a large amount of land and only 21% of MSW is properly managed. Landfills contribute significantly to greenhouse gas emissions and are expected to cause a substantial increase in global emissions in the future.

Summary: The study investigates the impact of different heating pretreatment techniques on Lantana camara to accelerate hydrolysis and enhance biogas production. Autoclave pretreatment was found to be the most efficient. It increased solubilization (45.44%) and volatile fatty acids (56.75%) at 110 degrees C for 80 min compared to the untreated control. Cumulative methane production increased from 2895 mL in 7 weeks to 3656 mL in 5 weeks following autoclave pretreatment. Thermal pretreatment of Lantana camara breaks down the rigid lignocellulosic structure, improving hydrolysis and biogas production simultaneously. This is the first thermal pretreatment study conducted on Lantana camara for biogas production.

Summary: This study used anaerobic digestion to convert ammonium-rich food waste digestate (FWD) into biofertilizer. By adding 10% tobacco and 10% bamboo biochar, nitrogen loss in FWD was reduced by 29-53%, NH3 emission was mitigated by 63% and 48%, and N2O emission was mitigated by 65% and 31%, respectively. Furthermore, the addition of biochar improved the biodegradation rate of FWD and resulted in mature compost within 21 days.

Summary: Natural astaxanthin is richer than synthetic astaxanthin, but cultivating it in photobioreactors is expensive and downstream processing techniques for solubilization are not cost-effective. As a result, the cost of astaxanthin is high, leading pharmaceutical and nutraceutical companies to opt for synthetic astaxanthin. This review discusses the chemical character of astaxanthin, more cost-effective cultivating techniques, and its bioavailability. Moreover, the antioxidant properties of this microalgal product against various diseases are discussed, which make it a promising drug for reducing inflammation and its consequences.

Summary: The blue-green city concept aims to reduce the impacts of stormwater by utilizing green infrastructure in metropolitan areas. The key types of blue-green infrastructures include wetlands, basins, green roofs, and permeable pavements. Bioretention systems, made of plants, mulch, and soil, have been enhanced by the use of biochar due to its adsorption capabilities. Although most studies on this topic have been conducted in labs, there is a need for field-based research to fully understand the efficiency of biochar-incorporated bioretention systems.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
