Abstract
Biomedical waste has become a serious health hazard in many countries including India. Careless and indiscriminate disposal of this waste by healthcare establishments and research institutions can contribute to the spread of serious diseases such as hepatitis and AIDS (HIV) due to injuries from sharps, needles and other types of material used when giving injections among those who handle it and also among the general public. The aim of the paper is to study the effect of lime solution and neem (Azadirachta indica) leaves extract for the disinfection of biomedical wastes was studied in laboratory.The study involves the determination of physio-chemical and biological parameters such as COD, Total Solids, Volatile Solids, Electrical Conductivity, Alkalinity, MPN Value, Bioassay and Microbial Colony Count at different stages of disinfection. There was remarkable reduction in all parameters suggest that pathogens of biomedical waste can be effectively destroyed using alkaline solution with respect to time whereas the reduction percentage are better in neem leaves extract.
