Sustainable organic biomedical waste management is a difficult challenge as this has become one of the serious hazardous wastes. Improper disposal of organic biomedical waste can lead to direct and indirect transmission of diseases. In the present research, the organic biomedical waste samples (32 g blood swabs, 12 g dressing swabs, and 6 g used cotton) were treated with Azadirachta indica ("Neem") and Nicotiana tabacum ("Tobacco") extracts at various concentrations and kept for 96-h degradation, followed by evaluation of physicochemical parameters. The physicochemical results of organic biomedical waste like pH of the experimental sets were within the optimum range and there was 63.33% of decrease of TDS, 86.15% and 95.30% reduction of BOD and COD, respectively was observed at the end of 96 h. The residues were mixed with 1000 g soil to confirm their role as a potential fertilizer. The physicochemical parameters of soil sample F (neem+tobacco) show an excellent result among all. The phytochemical parameters of a plant were also enhanced as compared to control. The soil samples and the tomato plants were also not polluted by the heavy metals, they are within the limit given by WHO. The present study deals with the conversion of organic biomedical waste into potential fertilizer by using plant extracts which can purely be financially profitable to the farmer.
可持续的有机生物医学废物管理是一个具有挑战性的问题，因为这已经成为严重的危险废物之一。有机生物医学废物处理不当会直接或间接导致疾病的传播。在本研究中，采用印楝（“Neem”）和烟草（“烟草”）提取物，以不同浓度处理 32g 血拭子、12g 敷料拭子和 6g 用过的棉花等有机生物医学废物样本，保持 96 小时降解，然后评估理化参数。有机生物医学废物的理化结果，如实验组的 pH 值在最佳范围内，实验结束时 TDS 降低了 63.33%，BOD 和 COD 分别降低了 86.15%和 95.30%。将残渣与 1000g 土壤混合，以确认其作为潜在肥料的作用。土壤样品 F（印楝+烟草）的理化参数在所有样品中表现出色。与对照相比，植物的植物化学参数也得到了增强。土壤样品和番茄植物也没有受到重金属污染，它们在世界卫生组织规定的范围内。本研究涉及利用植物提取物将有机生物医学废物转化为潜在肥料，这对农民来说纯粹是有利可图的。
