Medical waste disposal has become a significant concern globally, with the World Health Organization (WHO) estimating that approximately 85% of medical waste is non-hazardous, while 15% is hazardous and requires special treatment. In Kenya, the issue of medical waste management has been a burning problem, with many healthcare facilities lacking adequate disposal mechanisms. However, Siaya County Referral Hospital has taken a significant step towards addressing this problem by installing an incinerator to manage its medical waste.
The incinerator, which was commissioned in 2022, has the capacity to burn up to 500 kilograms of medical waste per day, making it one of the largest and most efficient in the region. The hospital’s decision to invest in an incinerator was driven by the need to reduce the risk of infection and environmental pollution associated with improper medical waste disposal. According to the hospital’s management, the incinerator has significantly reduced the amount of medical waste that is disposed of in landfills, thereby mitigating the risk of environmental pollution and promoting a healthier environment for patients, staff, and the surrounding community.
The Problem of Medical Waste in Kenya
Kenya generates an estimated 160,000 tonnes of medical waste annually, with a significant proportion of it being disposed of in landfills or through open burning. This has severe consequences for the environment, as medical waste contains hazardous materials such as plastics, chemicals, and infectious agents that can contaminate soil, water, and air. Furthermore, the lack of proper medical waste disposal mechanisms in many healthcare facilities in Kenya has been linked to the spread of diseases such as HIV, hepatitis, and tuberculosis.
How the Incinerator Works
The incinerator at Siaya County Referral Hospital uses a combination of heat and combustion to destroy medical waste, reducing it to ash and gases. The process involves several stages, including:
- Sorting and preparation of medical waste, which involves segregating hazardous and non-hazardous waste
- Feeding the waste into the incinerator, where it is burned at high temperatures (typically above 1000°C)
- Cooling and filtering of the gases and ash, which are then disposed of in a secure landfill
Benefits of the Incinerator
The incinerator at Siaya County Referral Hospital has several benefits, including:
- Reduced risk of infection and environmental pollution associated with improper medical waste disposal
- Decreased costs associated with medical waste disposal, as the hospital no longer needs to transport waste to landfills or other disposal facilities
- Improved compliance with regulatory requirements and international standards for medical waste management
- Enhanced reputation and credibility for the hospital, as it demonstrates its commitment to environmental sustainability and patient safety
