Waste Management: Compact Waste Incinerator

Waste Management: Compact Waste Incinerator

TESNA Energy Co., Ltd.

Compact and Safe Waste Incinerator
for Medical and Industrial Waste


ESNA Energy Co., Ltd. developed  the compact waste incinerator, which is a small, dependable waste incinerator designed for the safe and efficient disposal of medical waste, industrial waste, municipal solid waste and wood chips. Billed  as a safe and sustainable waste management system, this technology can be used within various types of facilities, such as hospitals, nursing homes, research institutes, industrial parks and factories.

The compact waste incinerator meets emission standards set forth by the Ministry of the Environment in Japan. In addition, this technology has a burning capacity of 50kg/hour (TDE-RC-50) and 80kg/hour (TDE-RC-80). Other capacities are available for customized applications.

The company is well known for its role in the woody biomass gasification plant business, using reformed gas to generate electric power as well as to produce hydrogen for fuel cells and industrial use.

Major Features and Advantages

I. Environmentally Friendly Design
The gas and ash that are discharged from this incinerator are non-hazardous. This is because the dioxin is eliminated as it passes through the two-chamber system. Dust is also removed via a cyclone separator. As such, this slashes the amount of dioxin in the exhaust to less than 0.06ng-TEQ/N (for TDE-RC-50). Clients also have the option of installing a PM2.5 emission control system.

II. Compact Design
Due to its compact design, the incinerator can be placed in facilities with limited spaces. This makes it possible for those facilities with small extra spaces to consider having their own in-house waste incineration system.

III. Easy to Operate
Thanks to automatic operation, the system is easy to operate. Ignition and temperature are automatically controlled.

IV. Low Fuel Consumption
Compared with a conventional incinerator, the TDE-Series system uses less fuel due to the adoption of a round chamber. This allows for optimal heat efficiency over the standard square chamber.

V. Long Life Span
The durability of this system is unparalleled, lasting for 10 years or more with proper operation and maintenance.

VI. Easy Waste Disposal
No need to segregate waste before disposing to the incinerator, which allows the batch disposal of waste possible and making the disposing process very easy. Waste can be disposed at any time during the incineration cycle.TESNA has sold 50 units of its Compact Waste Incinerator over the last 10 years.

Technology Data

Conceivable Applications

We offer a small but reliable waste incinerator for the disposal of medical waste, municipal solid waste, industrial waste, and wood chips. We believe that our waste incinerator can provide solutions for safe and sustainable waste management at various facilities.

Examples of facilities:

  • Hospitals: For medical waste such as used syringes, used gauze, pathological waste, etc.
  • Research institutes: For waste that is contaminated with hazardous substances.
  • Industrial parks and factories: For plastic waste, wood chips, and hazardous-substance- contaminated waste.
  • Homes for the aged: For medical waste such as used diapers and general waste.

Competitive Advantage

The most significant competitive advantages of our TESNA TDE Series Incinerator are the following:

  • Compact design: Installation in small spaces is possible.
  • Automatic operation: Ignition and temperature are automatically controlled.
  • Environmentally friendly: Discharged gas and ash are non-hazardous, because dioxin is eliminated in the series’ two-chamber system, and the dust is removed by a cyclone separator. The amount of dioxin in the exhaust is reduced to less than 0.06ng-TEQ/N (for TDE-RC-50). The system of PM2.5 emission control is also available to be installed as an additional option.
  • Low fuel consumption: The TDE- Series system uses less fuel than conventional incinerators of a similar size. This is because the TDE Series has a round chamber, which is better for heat efficiency than the conventional square chamber.
  • Long life: The system is durable and can last for 10 years or more under the appropriate operation and management.
  • Easy waste disposal: The segregation of waste is not necessary; the batch disposal of mixed waste is possible. You can throw in your waste at any time during the incinerating cycle.
