SOLID WASTE MANAGEMENT IN HOSPITALS “ Medical care is vital for our life and health, but the waste generated from medical activities represents a real problem of living nature and human world. Improper management of waste generated in health care facilities causes a direct health impact on the community, the health care workers and on the environment The Government of India (notification, 1998) specifies that Hospital Waste Management is a part of hospital hygiene and maintenance activities. This involves management of range of activities, which are mainly engineering functions, such as collection, transportation, operation or treatment of processing systems, and disposal of wastes.

SOLID WASTE MANAGEMENT IN HOSPITALS BIOMEDICAL WASTE MANAGEMENT PROCESS The hospital waste like body parts, organs, tissues, blood and body fluids along with soiled linen, cotton, bandage and plaster casts from infected and contaminated areas are very essential to be properly collected, segregated, stored, transported, treated and disposed of in safe manner to prevent nosocomial or hospital acquired infection. WASTE COLLECTIO N SEGREGATI ON TRANSPORT ATION AND STORAGE TREATMENT & DISPOSAL TRANSPORT TO FINAL DISPOSAL SITE FINAL DISPOSAL Example of vehicle used for transportation of biomedical waste. Nous Hospital Consultants Pvt. Ltd.
SOLID WASTE MANAGEMENT IN HOSPITALS PLANNING & DESIGNING FOR SOLID WASTE IN HOSPITALS A. SEGGREGATION OF WASTE AT THE POINT OF GENERATION § The waste is collected in three or four color coded containers and the sharps are collected separately in the sharp container B. TRANSPORT OF COLLECTED WASTED TO CENTRAL POINT OF DISPOSAL AND TREATEMENT • The waste shall be transported in covered trolleys, separate for each category C. TREATEMENT AT CENTRAL POINT • The segregated and collected waste shall be suitably treated as per DPCC norms by one autoclaving two disinfection three chemical sterilization • The waste shall be compacted either by pulverization and compaction or by simple compaction. D. FINAL DISPOSAL • Either the waste is handed over to a third party waste handling agency or by deploying waste handling technology like IGMET waste can be pulverized disinfected and compacted whereby the volume is reduced by 90% and then resultant compacted waste is disposed off to third party or municipal waste handlers.

SOLID WASTE MANAGEMENT IN HOSPITALS BIOMEDICAL WASTE TREATMENT & DISPOSAL Incineration Technology This is a high temperature thermal process employing combustion of the waste under controlled condition for converting them into inert material and gases. Incinerators can be oil fired or electrically powered or a combination thereof. Broadly, three types of incinerators are used for hospital waste: multiple hearth type, rotary kiln and controlled air types. All the types can have primary and secondary combustion chambers to ensure optimal combustion. These are refractory lined. Non-Incineration. Technology Non-incineration treatment includes four basic processes: thermal, chemical, irradiative, and biological. The majority of non-incineration technologies employ thermal and chemical processes. The main purpose of the treatment technology is to decontaminate waste by destroying pathogens. Facilities should make certain that the technology could meet state criteria for disinfection. Autoclaving Chemical Methods Microwave Irradiation Plasma Pyrolysis Nous Hospital Consultants Pvt. Ltd.

SOLID WASTE MANAGEMENT IN HOSPITALS NEED OF BIOMEDICAL WASTE MANAGEMENT IN HOSPITALS The reasons due to which there is great need of management of hospitals waste such as: Ø Injuries from sharps leading to infection to all categories of hospital personnel and waste handler. Ø Infections in patients from poor infection control practices and poor waste management. Ø Risk of infection outside hospital for waste handlers and scavengers and at time general public living in the vicinity of hospitals. Ø Risk associated with hazardous chemicals, drugs to persons handling wastes at all levels. Ø “Disposable” being repacked and sold by unscrupulous elements without even being washed. Ø Drugs which have been disposed of, being repacked and sold off to unsuspecting buyers. Ø Risk of air, water and soil pollution directly due to waste, or due to defective incineration emissions and ash 3. Nous Hospital Consultants Pvt. Ltd.
