Triclosan (TCS) is an anti-microbial widely used in personal care and medical antibacterial products. Despite the widespread occurrence of TCS municipal sewage sludge, understanding toward fate within treatment environmental risks eventual land application still limited. This review summarizes loads transfer mechanisms process, sludge management application, its potential impacts. from to mainly occurs primary sedimentation representing 2.50 4.58 times more compared secondary process. facilitated through adsorption because presence humic acid-like protein-like substances sludge. Both anaerobic digestion aerobic composting contribute degradation with being effective, exhibiting rates 1.04–2.87 higher than those observed digestion. After majorly dissipates soil biodegradation by fungi bacteria, potentially posing risks, such as inhibiting seedling growth plant species. Additionally, TCS, coupled formation subsequent MeTCS, observed, MeTCS a half-life greater toxicity parent compound (TCS). Overall, this research offers vital insights enhance TCS's migration processes soil. It also provides guidance protection sustainable resource management.

Sludge, as a sustainable energy source and pollutant matrix, necessitates effective management. The environmental, economic impacts of sludge management practices in Australia remained unknown. Furthermore, lignosulfonate addition was recently reported promising approach to enhance the production from sludge, benefits which on have not been explored. Life cycle assessment four scenarios: two traditional (A: land application digested B: composting before application) innovative (A B with during digestion process - C D) conducted. Traditional scenario A outperformed B, 2.24-fold reduction environmental footprints, 16.28-fold higher recovery, reduced expenditure reaching $78.23/t dry (DS). Scenario demonstrated superior results 1.26-fold decrease 1.51-fold more recovery than A, shift $5.36/t DS. Sensitivity analysis revealed sensitive sludge's total volatile solids content, highlighting importance optimization for best performance. These findings guide environmentally economically viable management, emphasizing efficient recovery.
