Contamination of heavy metals (HMs) in agroecosystem presented an additional dimension of complexity along with the adverse consequences of climate change for the scientific fraternity. The increasing population and urbanization on the other hand are regarded as the main sources of urban waste (UW). Holistic utilization of UW-derived biochar (BC) has shown potential to be utilized as a source of soil supplement in the agriculture sector, fulfilling several sustainable development goals (SDGs). An attempt has been made to evaluate the techno-economical prospect, efficacy of UW-BC in remediation HMs from SDGs and circular bio-economy prospective. Current review has highlighted that biochar, when amended alone/in combination, enhances HMs remediation potential. Economic analysis of UW-BC reinforces its viability as a sustainable solution for waste management. Consequently, the application of UW-BC has the potential to contribute significantly to the achievement of multiple SDGs, warranting further research and increased investment in this field.

College of Materials Science and Engineering, Xi'an University of Science and Technology, Xi'an 710054, China.
With the advancement of industrial production and urban modernization, pollution from heavy metal ions and the accumulation of solid waste have become critical global environmental challenges. Establishing an effective recycling system for solid waste and removing heavy metals from wastewater is essential. Coal gangue was used in this study as the primary material for the synthesis of a fully coal gangue-based phosphorus-silicon-aluminum (SAPO-5) molecular sieve through a hydrothermal process.

This study analyzes vegetation cover changes and their impact on UHI from 2000 to 2020 in three locations: Dexing City and Qibaoshan Township in China, and Dartford Ebbsfleet Garden City in the UK, using satellite imagery and remote sensing data. In Dexing City, the transition from open-pit to underground mining, combined with reclamation efforts, maintained a stable fractional vegetation cover (FVC) of 0.

Decentralized light greywater (LGW) treatment and reuse can help mitigate urban water scarcity, yet data on its characteristics at the household level in Latin America remain scarce, limiting system design and implementation. This study assessed LGW quantity and quality in a representative household in Bucaramanga, Colombia, and analyzed its implications for decentralized treatment and reuse. Potable water consumption and LGW production from showers and hand basins were monitored over 98 and 124 days, respectively, with 27 LGW samples collected for quality analysis.

Converting biomass waste into hydrogen energy through gasification is a crucial pathway for producing "green hydrogen". In a fixed bed reactor, a representative biomass waste, rice straw (RS), was pyrolyzed at N, HO, CO, and O atmospheres to generate hydrogen. Solid C-13 Nuclear Magnetic Resonance Spectroscopy (C-NMR) and Fourier Transform infrared spectroscopy (FTIR) were employed to elucidate the carbon structure and functional groups of the samples.
