We are a circular technology company
that returns discarded clothing back to the soil.

Service

VisionVision

Toward a society where all clothing
is returned as a resource.

End of waste,
beginning of renewal.

MissionOur Mission

  • Safely carbonize clothing including synthetic fibers without sorting, and regenerate them as soil amendments and recycled resources.
  • Provide an exit strategy for clothing that does not rely on incineration or landfill, implementing CO₂ reduction and a sustainable circular model.
  • Collaborate with diverse industries to drive the social shift from "discarding" to "returning."

Core ValueOur Core Values

  • CO₂ Reduction

    We reduce CO₂ emissions by approximately 80% compared to standard incineration disposal.

  • Returning to Soil Through Proprietary Technology

    Our unique carbonization technology regenerates clothing fibers into soil conditioners.

  • Achieving Decarbonization

    We provide clear solutions to the challenges faced by sustainability managers, driving decarbonized business with proven services.

ComparisonTextile Recycling Methods

Achieving 100% resource recovery. Reaching a level unattainable by other methods.

While material and chemical cycles require material separation and result in moderate to high levels of CO2 emissions, CIRCULAR CARBONs carbonization technology processes clothing, including blended materials and accessories, in a single batch without separation, achieving approximately 80% CO2 reduction compared to incineration. With a 100% recycling rate, it can be used in a variety of applications such as soil conditioners, building materials, and adsorbents, and significantly surpasses other methods in terms of alignment with SDGs 12 and 13.

ProcessRecycling Process

CIRCULAR CARBON Recycling Process

The materials are crushed and pulverized while removing accessories such as zippers and buttons, and then, using our unique carbonization equipment, harmful substances and microfibers contained in the synthetic fibers are thermally decomposed into safe carbonized materials.

The resulting carbonized material is transformed into a valuable recycled resource that can be used in a variety of applications, including soil conditioners, building materials, deodorizers, and molded products.

"Infinite possibilities"
We turn ideas into reality.

SolutionCreating New Value

Clothing reborn as abundant harvest

Circular Carbons unique technology recycles collected clothing into fibers, which are then used in agriculture as soil conditioners. This soil conditioner allows vegetables to thrive in soil with ideal growing conditions, enabling sustainable agriculture with minimal environmental impact.
Not waste, but a valuable resource.
Clothing returns to the soil, nurturing new life.
This is the true circular economy we propose.
