Conversion of organic biomedical waste into potential fertilizer using isolated organisms from cow dung for a cleaner environment
Résumé
Management of organic biomedical waste is a global quandary, and it is becoming difficult to confront day by day. Conversion of
organic biomedical waste into fertilizer is of great concern. In the present research, organic biomedical waste samples (blood
swabs, dressing swabs, and used cotton) were collected then after cow dung was collected in sterile container and immediately
transported to the laboratory and screened for any gastrointestinal infection by using routine microscopy for intestinal parasitic
infection, routine bacterial culture, and fecal occult blood for any intestinal bleeding. Then after, the pure culture of organisms and
fungus were prepared, and further samples were subjected to degradation for 288 h by using various organisms and fungus. Then
after, the specific quantity of biomedical waste was subjected for incineration. The physicochemical parameters of biomedical
waste samples were analyzed. Then treated samples were mixed with soil to confirm a role as potential fertilizer. Then after,
tomato plantation was done and phytochemical parameters of tomato plant were analyzed. This study states that organic
biomedical waste produces a sanitary and stable fertilizer.
