Pharmaceutical is one of the noteworthy classes of emerging contaminants. These biologically active compounds pose a range of deleterious impacts on human health and the environment. This is attributed to their refractory behavior, poor biodegradability, and pseudopersistent nature. Their large-scale production by pharmaceutical industries and subsequent widespread utilization in hospitals, community health centers, and veterinary facilities, among others, have significantly increased the occurrence of pharmaceutical residues in various environmental compartments. Several technologies are currently being evaluated to eliminate pharmaceutical compounds (PCs) from aqueous environments. Among them, adsorption appears as the most viable treatment option because of its operational simplicity and low cost. Intensive research and development efforts are, therefore, currently underway to develop inexpensive adsorbents for the effective abatement of PCs. Although numerous adsorbents have been investigated for the removal of PCs in recent years, biochar-based adsorbents have garnered tremendous scientific attention to eliminate PCs from aqueous matrices because of their decent specific surface area, tunable surface chemistry, scalable production, and environmentally benign nature. This review, therefore, attempts to provide an overview of the latest progress in the application of biochar for the removal of PCs from wastewater. Additionally, the fundamental knowledge gaps in the domain knowledge are identified and novel strategic research guidelines are laid out to make further advances in this promising approach towards sustainable development.

Municipal solid waste(MSW)generation and characterization are the basic inputs for waste handling and treatment systems *** present research,we performed waste characterization investigations in Visakhapatnam(India),using a waste characterization methodology by integrating two standard sampling and characterization *** characterization methodology was designed by combining seasonal variations,source,and socio-economic ***-based sampling was performed at household(s),dumpster(s),transfer station,and ***-economic-based sampling was performed based on the zone classification of the *** sampling campaigns were conducted to identify the waste composition based on seasonal *** aimed to perform stratified characterization of waste and assess chemical characteristics of the mixed waste fractions to evaluate waste-to-energy *** indicate that the amount of MSW generated in the city is 1250±100 tons/day,with a generation rate of 0.65 kg/capita/*** on source stratification,organic matter(45.5%±6.5%)is a major component followed by inert *** paper,plastic,and textile components amount to 25%of overall *** seasonal studies,organic matter was higher in pre-monsoon(42%)compared to winter(39%).The moisture content of MSW varied between 30%and 35%and volatile solids between 39%and 43%.The calorific value was determined to be between 5680-7110 kJ/*** the limitations and potential errors associated with sampling and waste *** and thermal conversion treatment alternatives for processing,treatment,and handling were *** findings of this research would assist regulatory bodies and city councils to formulate policy directives on waste sampling,characterization,segregation,education,and awareness campaigns.
