Tire Fuel Business

Our first initiative will be the “Recycled Fuel Refining Business from Waste Tires”. We manufacture biofuels from tire chips.

Benefits of using our fuel


It is an environmentally friendly renewable energy source. (fossil fuel free)


Unlike natural energy, we can provide a stable supply.


Carbon offsets reduce greenhouse gas emissions.


Various subsidies and grants for boiler installation can be expected.


Proactive use of renewable energy will be essential to improve corporate value, corporate image, and ESG management.


Refining Process

The key point in the business of refining recycled fuel derived from waste tires is the accuracy of the refining process.
We provide a one-stop service from raw materials of waste tires to biofuels.

Procurement of raw materials

Shredded and chipped waste tires are used as raw materials. Generally, 90% of collected scrap tires are crushed and distributed as tire-derived fuel (TDF).
While the amount of waste tires generated is increasing, the demand for fuel is decreasing and there is a surplus of waste tires, making it possible to procure cheap and stable fuel.

Oil conversion and refining

Tire chips are treated by oilification to separate them into waste tire crude oil, steel, and carbon black. This crude oil is refined into biofuel through a proprietary process.
Waste tire → oilification equipment → waste tire crude oil → refining equipment → biofuel (main product)
Carbon black, steel (byproduct)

Product Sales

We sell LSA heavy oil and recycled carbon black close to diesel oil specs. (Biodiesel will only be sold overseas.)
This recycled fuel can be used in a wide range of applications, including vehicles and ships, and will contribute to the reduction of greenhouse gas emissions as a carbon offset.

“Sales target of biofuel”
Boiler fuel for small and medium-sized factories, building heating fuel, fuel for ship diesel engines, fuel for heating plastic greenhouses, hotel and spa facilities (boiler fuel), fuel for diesel engines for agricultural and construction heavy machinery, fuel for ceramic furnaces, etc.

About Biofuels

The term “biomass” as commonly used refers to animal and plant resources and wastes derived from them (excluding petrochemical resources). This is also defined in the Basic Law on the Promotion of Biomass Utilization (June 2009).

The commonly used expression “biomass fuel (biofuel)” refers to fuel produced from biomass and thus defines the raw materials of the fuel.

Carbon neutral fuel is an expression that defines the product as a fuel. Biofuels are sometimes included, but more often refer to fuels synthesized from non-petrochemical feedstocks (e-fuel: synthetic fuels made from carbon dioxide and hydrogen).

Refined tire oil falls under the category of carbon neutral fuel.
However, tire refining oil is conveniently referred to as biofuel because it is closer to pure biomass fuel than synthetic fuels (derived from naturally occurring carbon).
