The effective management of waste-activated sludge (WAS) presents a significant challenge for wastewater treatment plants (WWTPs), primarily due to the sludge’s high content organic matter, pathogens, and hazardous substances such as heavy metals. As urban populations industrial activities expand, increasing volume WAS has intensified need sustainable solutions. Conventional approaches, landfilling anaerobic digestion, are frequently ineffective resource-intensive, particularly when dealing with protective extracellular polymeric (EPS) that render resistant biodegradation. Thermal pretreatment methods have gained attention their ability enhance biodegradability sludge, improve dewaterability, facilitate resource recovery. These processes function by breaking down complex structures within thereby its accessibility subsequent treatments digestion. integration thermal chemical can further optimize process, resulting in higher biogas yields, reduced pathogen content, lower environmental risks. While disintegration is energy-intensive, advancements energy recovery process optimization made it more viable environmentally friendly option. This approach offers pathway efficient practices, which align goals reducing waste complying stricter regulations.

This study aimed to create a comprehensive evaluation method for sewage sludge (SS) treatment and disposal technologies, considering carbon emission environmental impacts. Life cycle assessment (LCA) were conducted on six SS technologies in China. The assessments used the IPCC factor approach calculate emissions CML2001 determine impact factors. Additionally, colour-coded was implemented quantify results. found that S1 (anaerobic digestion + land application) had lowest impact, making it optimal technology. scenario of 669 kg CO2(t DS)−1 impacts 5.20E-10. A sensitivity analysis show each unit total results showed landfilling has high Therefore, controlling greenhouse gases toxic substances landfills is crucial reducing pollution.

This study presents the technological, technical, and economic basis of solution developed by authors for production biomethane based on pretreatment organic substrates at low temperature using solidified CO2 captured during biogas upgrading in a closed cycle (TeCH4BiogasUp). TeCH4BiogasUp integrates disintegration substrates, sequestration utilization cycle. The multifunctional hybrid nature sets it apart from other available solutions that only perform selected, individual technological processes. is significant advantage competitive market edge; however, also poses challenges conducting comparative analyses with existing market. technology has been compared traditional substrate techniques purification technologies. Considering origin CO2, this method can be regarded as material recycling, which aligns fully principles circular economy. supports reduction emissions capturing introducing into process. novel approach to largely overcomes previous limitations associated profitability could serve viable alternative methods, particularly light trends imperative reduce through development renewable energy sources.
