The United Nations proposed the Sustainable Development Goals with aim to make human settlements in cities resilient and sustainable. excessive discharge of urban waste including sludge garden can pollute groundwater lead emission greenhouse gases (e.g., CH4). proper recycling is essential for responsible consumption production, reducing environmental pollution addressing climate change issues. This study aimed prepare biochar high adsorption amounts iodine using peach wood from waste. was conducted examine variations mass ratio between (2/1, 1/1, 1/2) as well pyrolysis temperatures (300 °C, 500 700 °C) on carbon yield capacities biochar. Scanning electron microscopy, Brunauer–Emmett–Teller analysis, Fourier transform infrared spectrometry, powder X-ray diffraction, elemental analysis were used characterize produced at different ratios. results indicate that found be highest (>60%) a temperature 300 °C across temperatures. absorbed aqueous solution ranged 86 223 mg g−1 1:1 wood, which comparably higher than those observed other advances water treatment by offering cost-effective method derived processing

Due to its high nutrient utilization efficiency, liquid organic fertilizer has become a research hotspot in the field of agricultural planting. Artificial humic acids, which are near-nature products, can be deemed as green fertilizer, but few studies have been reported, limited their further application. In this study, artificial acids were derived from municipal sludge, and effect on rice growth, soil fertility, dissolved matter was investigated using multi-chamber root box experiments. The shoot biomass significantly enhanced by heavy metal concentration within safe limits. limit decrease pH, especially far-rhizosphere zone, improve distribution nutrients rhizosphere, near-rhizosphere, zones. use led significant electrical conductivity. carbon content zone increased, fluorescence intensity rhizosphere increased. proportion specific components just slightly changed near-rhizosphere promoted humification findings indicate that environmental impact is different conventional chemical fertilizers, they show huge potential agriculture field.
