Waste Incineration in Kenya: A Case Study of the Chemelil Sugar Company Health Centre Facility
Introduction
Waste incineration is a widely practiced method of waste disposal globally, where waste is burned at high temperatures to reduce its volume and potentially generate energy. In Kenya, waste incineration is also used as a means of managing waste, particularly in healthcare facilities where infectious and hazardous waste is generated. This news focuses on a case study of the Chemelil Sugar Company Health Centre facility, which utilizes waste incineration as a primary method of waste disposal.
Background
The Chemelil Sugar Company Health Centre is a medium-sized healthcare facility located in western Kenya, providing medical services to employees of the Chemelil Sugar Company and surrounding communities. The facility generates a significant amount of waste, including infectious and non-infectious waste, such as sharps, swabs, and pathological waste. Prior to the introduction of waste incineration, the facility faced significant challenges in managing its waste, including overflowing waste bins and inadequate disposal methods.
Waste Incineration Facility
In 2015, the Chemelil Sugar Company Health Centre facility installed a waste incineration plant to manage its waste. The incinerator is a small-scale, brick-lined unit with a primary combustion chamber and a secondary air supply system. The facility is designed to burn 50 kilograms of waste per hour, at a temperature of 1000°C. The incinerator is equipped with a scrubber system to remove particulate matter and gases from the flue gas emissions.
Operation and Maintenance
The waste incineration facility at the Chemelil Sugar Company Health Centre is operated by trained personnel who ensure that the incinerator is functioning correctly and that waste is fed into the incinerator in a controlled manner. The facility is maintained regularly, with daily cleaning and weekly inspections to ensure that the incinerator is in good working condition. The facility also has a system for monitoring emissions, which includes a particulate matter (PM) monitor and a gas analyzer.
Environmental and Health Impacts
The waste incineration facility at the Chemelil Sugar Company Health Centre has had significant environmental and health impacts. The incinerator has reduced the amount of waste sent to landfills, minimizing the risk of waste leachate contaminating groundwater sources. However, the facility has also raised concerns about air pollution, with nearby residents complaining about particulate matter and gas emissions from the incinerator. The facility has implemented measures to minimize emissions, including the installation of a scrubber system and the use of alternative fuels, such as biomass.
Challenges and Limitations
Despite the benefits of waste incineration, the Chemelil Sugar Company Health Centre facility faces several challenges and limitations. One of the major challenges is the lack of adequate training for personnel operating the incinerator, which can lead to poor maintenance and operation of the facility. Additionally, the facility lacks a comprehensive waste management plan, which can result in inadequate segregation and handling of waste. The facility also faces challenges in managing hazardous waste, such as batteries and electronics, which require special handling and disposal procedures.

The Chemelil Sugar Company Health Centre facility is a case study of waste incineration in Kenya, highlighting both the benefits and challenges of this waste disposal method. While waste incineration has reduced the amount of waste sent to landfills and minimized the risk of environmental pollution, it also poses significant environmental and health risks if not properly managed. The facility’s experience demonstrates the need for comprehensive waste management planning, adequate training for personnel, and regular maintenance of waste incineration facilities to minimize environmental and health impacts.
Recommendations
- Comprehensive Waste Management Planning: The Chemelil Sugar Company Health Centre facility should develop a comprehensive waste management plan that includes waste segregation, handling, and disposal procedures.
- Training and Capacity Building: The facility should provide regular training and capacity building for personnel operating the incinerator to ensure that they have the necessary skills and knowledge to manage the facility effectively.
- Emissions Monitoring: The facility should establish a system for monitoring emissions, including particulate matter and gas emissions, to minimize environmental and health impacts.
- Alternative Waste Disposal Methods: The facility should explore alternative waste disposal methods, such as recycling and composting, to minimize waste sent to landfills and reduce the environmental impacts of waste incineration.
By implementing these recommendations, the Chemelil Sugar Company Health Centre facility can minimize the environmental and health impacts of waste incineration and ensure that waste is managed in a safe and sustainable manner.
