HISTORY OF BIOMEDICAL WASTE August 13, 1987, prompted expansive closures of

numerous New Jersey and New York beaches due to

a “30-mile garbage slick” composed primarily of medical and household wastes because of illegal disposal of the waste

private waste contractors to dump illegally to avoid high fees.

Medical Waste Tracking Act of 1988 (MWTA).

NEED FOR BMW MANAGMENTNosocomial infections in patients from poor

infection control practices and poor waste management.

Drugs which have been disposed of, being repacked and sold off to unsuspecting buyers.

Risk of air, water and soil pollution directly due to waste, or due to defective incineration emissions and ash.

Risk of infection outside hospital for waste handlers and scavengers, other peoples.

OBJECTIVE OF BMW MANAGEMENT• TO MINIMIZE THE PRODUCTION/GENERATION OF

INFECTIVE WASTE.• RECYCLE THE WASTE AFTER TREATING TO THE

EXTENT POSSIBLE.• TREAT THE WASTE BY SAFE AND ENVIORNMENT

FRIENDLY/ACCEPTABLE METHODS.• ADEQUATE CARE IN HANDLING TO PREVENT

HEALTHCARE-ASSOCIATED INFECTIONS.• SEFTY PRECAUTIONS DURING HANDLING THE BMW.

ENVIRONMENTAL LEGISLATION

The Environment (Protection) Act, 1986 The Biomedical Waste (Management & Handling)

Rules, 1998 The Municipal Solid Waste (Management &

Handling) Rules, 2000 The Hazardous Waste (Management & Handling)

Rules, 1989 The National Environmental Tribunal Act, 1995 The Air (Prevention and Control of Pollution) Act,

1981

CONCLUSION• Thus refuse disposal cannot be solved without public education.• Individual participation is required.• Municipality and government should pay importance to disposal of waste economically.• Thus educating and motivating oneself first is important and then preach others about it.• Start disposing waste first from within your home, then outside home, then neighborhood ,then your street, your area ,city and then the nation and the world.• Lets make this world a better place

to live in. 45
