Summary: Quinoa is a South American plant that has gained attention for its nutritional properties. The Red Faro variety of quinoa grown in Tunisia showed increased levels of antioxidants and enzyme activity under salt stress conditions. However, salt stress had negative effects on seedling growth. These findings suggest that stress conditions can enhance the production of biologically active molecules for potential nutraceutical applications.

Summary: Energy crisis and strict management standards are challenging solid waste management worldwide. Emerging diseases like COVID-19 have worsened the already complex solid waste crisis, particularly in sewage sludge and food waste streams due to increasing production. This paper reviews recent advancements in sewage sludge disposal technologies, including incineration, anaerobic digestion, and valuable product conversion. The paper also describes food waste disposal technologies, such as thermal treatment, fermentation, value-added product conversion, and composting. The hot topics and major research focuses in each area are summarized and compared to conventional technologies in terms of organic matter degradation, energy generation, and renewable resource production. The future prospects and potential challenges of each technology are discussed, with a positive impact on their implementation.

Summary: The perception of anaerobic digestion (AD) plants in host communities in Slovakia varies depending on the community's experience with and proximity to the plants. The study found that in communities where the planning and operation of AD plants were smooth or where the project was stopped, the attitudes towards AD plants remained constant. However, in communities where issues with AD plant operation arose, the overall support for biogas energy significantly decreased. Interestingly, positive local experiences with biogas supported further development of AD plants only if they were located outside of the host communities.

Summary: The importance of green technologies is increasing, with salt-tolerant plants proposed as energy crops for cultivation on saline lands. However, the different salt tolerance mechanisms of halophytes may have adverse effects on the anaerobic digestion process for biogas production, requiring adjustments for stable and efficient conversion. Despite this challenge, halophyte plants have great potential for biogas production with yields similar to other energy crops and the benefit of utilizing saline soils.

Summary: In India, rural areas account for only 23% of national electricity usage, highlighting the need to expand access to electricity for sustainable development. Biomass, particularly in the form of biogas produced from organic waste, provides a simple and direct energy source for cooking, heating, and electricity generation in rural households. Biogas production offers a pathway to generate electricity in villages through technologies like Solid Oxide Fuel Cells, ultimately bringing power closer to rural communities.

Summary: This study investigated the potential of biochar derived from urban organic wastes (UOW) in India to sequester carbon in soils. The chemical properties and thermal oxidative stability of biochars gained from three major UOW sources were examined. A modified thermal oxidative recalcitrance index (TORi) was proposed to evaluate the stability of these biochars. The results showed that the blend of 50% sewage sludge, 30% banana peduncles, and 20% anaerobic digestate exhibited the highest recalcitrance to become a long-term carbon sink in soil. The influence of Si, Fe, and alkaline earth metals on the biochar matrix affected its recalcitrance.

Summary: Walnut shell biochar (BWS0) derived through uncontrolled pyrolysis shows promising carbon structure and environmental applicability for carbon sequestration, soil amelioration, and pollutant adsorption. It can also be hybridized as magnetic biochar with high surface area and controllable pore structures for efficient adsorption of cations and hydrophobic pollutants. When combined with fast-release N, P fertilizers, BWS0 is suitable for application in hydrophilic soils. Further research on soil incubation and adsorption tests is recommended.

Summary: The increase in mineral and ash-rich waste biomass generation in emerging economies poses critical environmental problems and bottlenecks the solid waste and wastewater treatment systems. Transforming these waste biomasses to biochar through pyrolysis can be a sustainable method for their disposal and resource recovery. However, the limited organic content and possibly contaminated nature of the waste biomasses may restrict the applicability of the biochar. This study investigates the physicochemical properties and carbon sequestration potential of biochar derived from the co-pyrolysis of sewage sludge with other waste biomasses, and explores its potential benefits in soil improvement and heavy metal reduction.

Summary: Organic waste generated onboard cruise ships can be effectively converted into biogas through onboard anaerobic digestion, providing a complementary energy source for ship operation. Detailed investigations showed that each person onboard produces an average of 9 kg of organic waste daily, with a potential biogas yield of around 159 L per person per day. Co-digestion of sewage sludge and food waste proved particularly effective, increasing biogas yield by 24% compared to mono-fermentation and potentially covering 3.3% to 4.1% of a cruise ship's total energy demand.

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.
