Recycling efforts

Tsuneishi Kamtecs actively promotes recycling to reduce the load on the global and regional environments.

Thermal recycling
Power generation

Thermal energy generated from incineration of solids is collected as steam for power generation.
We reduce the consumption of valuable energy resources and contribute to CO2 emissions reduction.

Material recycling
Civil engineering or
construction materials

Incineration ash generated from incineration of solids, incineration fly ash, and cinders, fly ash and polluted soil received from outside are melted in the melting furnace. The obtained molten slag (Melissa) is used as civil engineering or construction materials.

Recycling of incineration ashRoad material

We accept incineration ash from general waste and industrial waste and conduct calcination of said ash. Calcined incineration ash is detoxified and processed as artificial sand.
Processed artificial sand is used as road bed material and braille block for roads, weed inhibiting material and water quality improving material.

Recycling of waste plastics,
wood chips and waste paper
RPF (solid fuel)

Using waste plastics, wood chips and waste paper as materials, the solid fuel called RPF is produced. RPF is an ideal high-calorie solid fuel and is used for furnaces at paper mills, etc.

Recycling of waste tires

We accept waste tires to sell domestically as used tires and to process into chips

Recovered oil

Tsuneishi Factory undertakes ship' tank cleaning, which has been one of our businesses since our founding.
Waste liquid discharged during cleaning of a ship's tank is recycled to produce recovered oil that can be used as heavy oil. We contribute to the effective use of limited oil resources through production of recovered oil.


With our proprietary self-fermentation system, organic waste is fermented to produce organic fertilizer for sale.
In the sludge fermentation method with the microorganisms we have developed, organic matters contained in sludge and oxygen in the air are given to microorganisms for fermentation, and heat generated from the fermentation is used to evaporate water in the sludge. This method only consumes a little energy and is' very economical.
