Small-type Incinerator for Medical WasteNU-100/100B
The NU100 has been produced as a small-type incinerator for medical waste, which has passed the Ministry of Environment’s regulations for dioxin emission. (Patented in 2011.) This is based on the knowledge and design of the thermal dissolved gasification burning system making use of radiant heat generated from fuel burning in the fire grate located above the waste vessel of the incinerator that was researched and developed in Nagasaki University.
Through the incineration process of highly infectious medical wastes within the hospital premises, the spread of infection to nearby communities could be prevented, and currently, it plays an important role as a tool to resolve the pressing issues of medical waste management within hospital premises in developing countries. Through JICA’ s Infection Prevention Reinforcement Program, since our provision of 26 units to Cambodia, we have continuously provided incinerators to the South Pacific islands, Laos, and the Democratic Republic of Congo, making use of the Japanese government’s Grant Aid program (Grassroots Funds) and Rotary Club’s Fund.

- 1. Dioxin concentration in the flue gas is less than 5-ng/Nm3, to clear the Japanese Air Pollution Control Law.
- 2. Fuels are either one of Kerosene or Gas oil.
If needed, firewoods locally available and carbon neutral biomass can be used. - 3. Solar powered draft fan is equipped to maintain high temperature inside the combustion chamber higher than 800 °C.
- 4. The NU100 employs a thermal dissolved gasification burning system making use of radiant heat generated from fuel burning on the fire grate located above the waste vessel to burn medical wastes such as syringes with needles, plastic bags, etc.
- 5. The NU100 is able to operate continuous batch burning. Owing to the negative inner pressure in the combustion chamber, the waste vessel can be safely pulled out to supply another batch of medical waste without stopping the on-going incinerating process.
