The problem of food being wasted in households has become an essential challenge recent years. Food waste can be valorized accordance with the principles sustainable development, including as a source energy. This study analyses potential anaerobic fermentation, pyrolysis, ethanol incineration, and composting to treat waste, focusing on its energy yield. research considered two scenarios for generating Poland both near term (2030) long (2050). Scenarios were proposed regions different levels urbanization demographic trends. criteria selection technologies energy-efficient processing from identified, taking into account current state these technologies, their prospective changes, nature regions, trajectory generation, spatial generation rate, potential. Technologies like methane fermentation thermochemical methods should developed densely populated areas high rate. Among processes, fast pyrolysis will provide most significant benefits, followed by moderate biocarbonization—at similar levels. Incineration is placed between carbonization gasification. In less lower rates, combining substrates co-processing green considered. Biocarbonization systems integrated rural regions.

Application of PTFE composite catalytic filter material in synergistic purification of multiple pollutants in waste incineration flue gas

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 25, 2025

The effective management of pollutants in waste incineration flue gas remains a critical challenge environmental protection. This study develops novel vanadium (V), molybdenum (Mo)/cerium (Ce), titanium (Ti)–polytetrafluoroethylene (VMo/CeTi-PTFE) composite catalytic filtration material to address the simultaneous removal multiple purification. A systematic investigation its performance and reaction mechanisms reveals that coating process optimizes pore structure material. While specific surface area is slightly reduced, increased volume diameter facilitate diffusion enhance efficiency. Experimental results demonstrate under high catalyst loading conditions, this exhibits outstanding denitrification, dioxin degradation, particulate removal, maintaining consistently dust efficiency over 99.97%. Additionally, binder content enhances mechanical stability, while water sulfur resistance tests confirm exceptional durability. Mechanistic analysis indicates significant synergistic effect between denitrification degradation. Specifically, − OH groups promote cleavage C–Cl bonds, enabling efficient degradation simultaneously improving nitrogen oxide (NOx) reduction suppressing formation byproduct nitrous (N2O). provides solid theoretical foundation technical support for design multifunctional purification materials underscores their broad application potential managing complex pollutants. findings have important implications enhancing benefits purification, representing step toward more cost-effective, efficient, environmentally friendly treatment solutions.

Nature-Based Solution for Wastewater Treatment and Reuse Using Phytoremediation with Floating Plants

Water, Journal Year: 2025, Volume and Issue: 17(7), P. 1080 - 1080

Published: April 4, 2025

Effective wastewater management is a critical environmental challenge, particularly in industrial regions like Faisalabad, where untreated textile effluents contribute to severe water pollution. This study evaluates the potential of phytoremediation using floating aquatic plants—Eichhornia crassipes (water hyacinth), Pistia stratiotes lettuce), and Lemna minor (common duckweed)—for treatment wastewater. A controlled laboratory-scale experiment was conducted assess pollutant removal efficiency over 10-day retention period. The initial effluent concentrations key parameters were measured before establish baseline conditions. results demonstrated that Eichhornia exhibited highest efficiency, achieving reductions 36.12% (TDS), 36.14% (EC), 36.30% (salinity), 6.12% (pH), 34.30% (total hardness), 44.52% (chloride). Furthermore, effective removing nitrate (99.76%), ammonium (52.11%), sodium adsorption ratio (46.29%), indicating species-specific potential. These findings highlight viability low-cost, eco-friendly, sustainable nature-based solution for clusters, offering practical alternative conventional technologies.
