Nicholas Kasekende and Dr. Moses Kizza Musaazi
The T4T Mak IV Incinerator is a solid waste incinerator manufactured and distributed in Kampala, Uganda.
The T4T Mak IV Incinerator is a solid waste incinerator that turns waste into ash while avoiding the spreading of toxic gases. It is specially targeted at health facilities for safe incineration of hospital waste but can also be used in schools, universities and other complexes with a substantial waste generation.
The Incinerator is made and sold by Technology for Tomorrow Ltd (T4T), a company which has its roots in research and development at Makerere University. Examples of clients the incinerator has been sold to are local governments, EGPAF, Mercy Corps, Baylor Uganda, ICRC and Save the childreninterview withmanufacturer

Incinerators were in use at the Makerere University but not any longer due to new regulations in Kampala. 6 have been installed in Soroti and a new installation is planned in Mokono in september 2017.interview with manufacturer
The incinerator has 3 chambers. The first chamber is the biggest one and where the solid waste is loaded in batches. The other two chambers are made in proportion to the first chamber. The gases from the burning are retained in the second and third chamber so that when they get out there is only colourless smoke. The incinerator is first loaded with paper but after about 15 minutes, when a yellow flame is seen in the third chamber, the incinerator is ready to be loaded with medical waste.Radio interview with creator

The T4T Mak IV Incinerator has a lifetime of 5 years when used about 4 hours per day.
The incinerator destroys 15 kg/hour. It takes 25 to 60 minutes to warm up the system and the medium temperature in the 3 chambers is 850 C but can reach up to 1050 C. The volume of the waste is reduced with 95% and combustion efficiency is at least 98%.
The incinerator will reach temperatures up to 1050 degrees celsius which composes a safety risk. T4T can train the client so that usage and maintenance is done properly. By using the incinerator to burn medical waste the spread of diseases and environmentally toxic substances can be reduced.
A turbine for electricity production. The energy from burning can be used to heat water into super-heated steam which can then be used to generate electricity by turning a turbine or sterilize medical equipment.
The incinerator complies with regulations in Uganda but cannot be used for general waste in Kampala because there is a recent law in Kampala that makes it illegal to use incinerators for all waste apart from medical waste. Hence the incinerators that were used in the capital are not in use there any longer. This law does not apply to the rest of the country though.interview with manufacturer
The incinerator has a recommendation to be used for medical waste management by the Ugandan Ministry of Health.
Temperature reached, robustness and time to burn waste are evaluation criteria.
T4T has made several models of the incinerator with different sizes and target users. The price and performance varies according to model. For example the price (product only) ranges from 2,735 USD to 16,800 USD and lifetime spans from 4 to 8 years.
