Enormous quantities of waste such as lawn waste (LW) and kitchen waste (KW) are generated in urban institutes, proper management of which is crucial. The present work was designed to bio-convert LW and KW amended with buffalo dung (BD) into humus-rich manures through composting and vermicomposting technology over a period of 3 months. At the termination of vermicomposting process, there was significant decline from initial value in certain parameters like pH (8.17–6.74), total organic carbon (36.12–28.04) and C:N (39–16), whereas increase was observed in parameters like electrical conductivity (1.19–3.22), N (1.35–1.89%), P (0.18–0.44%), K (0.78–1.06%). Concentration of toxic heavy metals (Co, Cd, Cu, As, Cr, and Pb) declined significantly in the end product. Fecundity of earthworms was favored more by higher proportion of BD, moderate KW, and 10% LW in the feedstock, and was maximum in the combination (BD60% + LW10% + KW30%) followed by (BD50% + LW0% + 50%), (BD40% + LW20% + KW40%) and (BD30% + LW20% + KW40%). Enzymatic activities such as urease, phosphatase, and dehydrogenase were found to be high initially, but declined towards maturity of the vermicompost. The study shows that buffalo dung, kitchen waste, lawn waste (6:1:3 ratio) give best quality vermicompost.

城市研究所产生了大量的废弃物，例如草坪废弃物（LW）和厨房废弃物（KW），对其进行适当的管理至关重要。本研究旨在通过堆肥和ver堆肥技术，在3个月的时间内将用水牛粪（BD）改良的LW和KW生物转化为富含腐殖质的肥料。在ver堆肥过程结束时，某些参数（例如pH（8.17–6.74），总有机碳（36.12–28.04）和C：N（39–16））比初始值显着下降，而诸如电导率（1.19–3.22），N（1.35–1.89％），P（0.18–0.44％），K（0.78–1.06％）。最终产品中有毒重金属（Co，Cd，Cu，As，Cr和Pb）的浓度显着下降。higher的繁殖力更受原料中BD的比例较高，中等KW和LW的10％的支持，在组合中最高（BD60％+ LW10％+ KW30％），其次是（BD50％+ LW0％+ 50％） ），（BD40％+ LW20％+ KW40％）和（BD30％+ LW20％+ KW40％）。最初发现酶活性（例如脲酶，磷酸酶和脱氢酶）较高，但随着com杂的成熟而降低。研究表明，水牛粪，厨房垃圾，草坪垃圾（比例为6：1：3）可提供最佳质量的ver石。
