The current global greenhouse gas emissions have increased by over 90% since 1860 primarily due to our overreliance on fossil fuels, petrochemicals and their derivatives. Production of petrochemical plastics is also reaching 400 million metric tons in 2023. The lack of effective thermochemical processes for converting wet feedstocks and complex residues such as plastics is calling for hydrothermal

Improper disposal of organic waste leads to greenhouse gases, pollution, and health risks. Anaerobic digestion offers a sustainable solution by converting this waste into biogas and digestates, which contain valuable nutrients and stimulatory organic compounds that can be recycled to improve plant growth and support food production. Here we review the transformation of liquid and solid digestates into

Contamination of drinking water sources with recalcitrant organic pollutants is a major health issue requiring advanced oxidation processes for the degradation of such pollutants. Here we review the use of advanced oxidation processes-based treatment of water, wastewater, and sludge, with focus on singlet oxygen production, reactivity mechanisms, and applications. Processes for single-oxygen production

Solvent selection is essential for industrial and analytical extraction processes to ensure environmental safety and neutrality. Nevertheless, toxic and hazardous solvents are often used, due to their cost-effectiveness and ready availability. In green chemistry, alternative solvents such as supramolecular deep eutectic solvents are gaining attention due to their superior performance compared with
