What Returnable does

Returnable Co., Ltd. (株式会社Returnable) is a Tokyo-based privately held company founded on March 3, 2021, with registered capital of 517 million yen. The company's core business is the refining of waste tire chips into biomass fuel through a proprietary two-stage process: thermal decomposition (oilification) followed by catalyst-based refining that yields a Grade A heavy oil equivalent with 93% biomass degree, verified to ASTM D6866-21 by the Institute of Accelerator Analysis Ltd. The process is designed to be non-incineration with zero dioxin emissions, and generates recycled carbon black and steel as saleable byproducts. Returnable serves industrial and commercial fuel buyers — factories, shipping companies, agricultural operators, building owners, and ceramic manufacturers — through direct B2B sales within Japan, and pursues overseas expansion for biodiesel (which is restricted domestically) via partnerships with JFE Shoji Corporation (JFE Group's trading arm) and Impact Co., Ltd.

The company supplements its core fuel business with a portfolio of solution/agency businesses — natural refrigerant distribution (with GAIA Solutions), Multi Internet connectivity (with Japan Sogo Gijutsu), and Health Management DX (with Personal Health Tech) — as well as ESG venture investment in environmental startups. In April 2023, Returnable acquired 90% of Takizawa Sangyo Co., Ltd., a 60-year-old agricultural materials company in Nagano Prefecture, providing both a downstream channel for agricultural fuel applications and a legacy revenue base. The company's go-to-market combines direct sales to industrial end-users with policy engagement (presentations to LDP Parliamentarians for Renewable Energy) and a multi-language web presence (Japanese, English, Simplified and Traditional Chinese) targeting international expansion. As of mid-2026, Returnable has filed a patent for a next-generation PFAS processing technology and signed a joint research agreement with Sumitomo Heavy Industries to validate its oilification platform across additional raw materials.

Revenue model

1. Biomass Fuel Manufacturing and Sales: Revenue generated from the production and sale of refined biofuel (LSA heavy oil equivalent, carbon neutral fuel) derived from waste tire chips, along with byproduct sales of recycled carbon black and steel. Biodiesel sales are restricted to overseas markets only per Japanese regulations. Products target boiler fuel, ship diesel engines, building heating, agricultural machinery, and ceramic furnace applications.
2. Solution/Consulting Services: Providing renewable energy business expertise, operational know-how, and consulting solutions to external business partners including corporations and municipalities seeking to implement biomass fuel operations. Services also extend to overseas partners for global expansion.
3. ESG Investment: Providing risk capital to innovative venture companies in the environmental sector, with active management and business expansion commitment to enhance corporate value. Investment in startups pursuing environmental technologies.
4. Natural Refrigerant Distribution: Partnering with a major hydrocarbon refrigerant manufacturer (H company) to promote natural refrigerants as a replacement for synthetic refrigerants (CFC, HFC, HCFC) in air conditioning, refrigeration, and heating equipment.
5. Multi Internet Services: Partnering with Japan Sogo Gijutsu (Japanese General Technology) to promote internet connectivity solutions using existing power lines, telephone lines, coax, and fiber optics — targeting warehouses and logistics facilities for IoT, security cameras, and connectivity infrastructure.
6. Health Management DX Services: Partnering with Personal Health Tech to offer corporate health management digital transformation services, including health checkup data processing, secondary examination coordination, health management apps, and human capital reporting for compliance with Japanese disclosure requirements.
