Sewage sludge (SS) is increasingly used as an environment functional material to reduce or control pollution and improve plant growth because of the large amounts of carbon and essential plant nutrients in it. To achieve the best application results, it is essential to comprehensively review recent progress in SS utilization. This review aims to fill the gaps in knowledge by describing the properties of SS, and its usage as adsorbents, catalysts and fertilizers, and certain application mechanisms. Although SS generates several benefits for the environment and humans, many challenges still exist to limit the application, including the risks posed by potentially toxic substances (e.g., heavy metals) in SS. Therefore, future research directions are discussed and how to make SS applications more feasible in terms of technology and economy.

The release of common medications and illegal drugs into the environment could be potentially harmful to the ecosystem and hamper the behavior and growth of plants and animals. These pollutants gain access to water through sewage and factory discharges and have been found to exceed safety limits in water bodies. Therefore, there is an urgent need for improved wastewater purification systems.

Soil heavy metal contamination and sludge disposal have become globally environmental issues problems of great concern. Utilizing sludge pyrolysis to produce biochar for remediating heavy metal-contaminated soil is an effective strategy to solve these two environmental problems. In this study, municipal sewage sludge and papermaking sludge were used as feedstock to prepare co-pyrolyzed biochar, which was then applied to reduce the toxicity of Cd in soil.

Background: Wastewater systems are usually considered antibiotic resistance hubs connecting human society and the natural environment. Antibiotic usage can increase the abundance of both ARGs (antibiotic resistance genes) and MGEs (mobile gene elements). Understanding the transcriptomic profiles of ARGs and MGEs remains a major research goal.

Polylactic acid (PLA) is a biodegradable alternative to traditional plastics due to its excellent biocompatibility. However, PLA is challenging to fully degrade and can easily become microplastics (MPs) in surface water, a process accompanied by aging. This study found that aged PLA (APLA) MPs exhibited increased surface roughness, decreased surface potential, and more oxygen-containing functional groups compared to PLA.

In this study, a hydroxylamine (HA)-enhanced magnetic spinel catalyst CuFeO-activated peroxymonosulfate (PMS) system (CuFeO/PMS/HA) was constructed to degrade Sulfamethoxazole (SMX). Results from experiments and theoretical calculations indicated that active species generation mechanism involved the direct activation of PMS by HA, the redox cycles acceleration on the surface of CuFeO by HA, and the synergistic action of the low valence Fe and Cu species in CuFeO for PMS activation. The efficacy of other organic pollutants removal was further validated in bio-treated landfill leachate through removal performance and toxicity assessment.
