Cosmo Energy Holdings and S-Bridges Collaborate on Bioethanol Production Technology from Food Processing Residues
Tokyo, Japan — Cosmo Energy Holdings Co., Ltd. has announced a strategic collaboration with S-Bridges corp. to jointly develop innovative technology for producing bioethanol from food processing residues.
S-Bridges has pioneered a proprietary extraction process that isolates valuable components such as fertilizers and proteins from non-edible plant materials, including tea leaves and coffee grounds. Following extraction, the remaining cellulose fibers are provided to Cosmo Energy Holdings, which applies saccharification and fermentation techniques to produce ethanol. A distinctive feature of this process is that the cellulose, once extracted, is in a state highly conducive to saccharification. This reduces the energy required for saccharification and pretreatment, thereby enhancing economic efficiency.
Laboratory-scale trials have already demonstrated successful extraction of useful components and ethanol production. Building on these results, S-Bridges plans to collaborate with multiple food and beverage manufacturers, with trial operations of a compact demonstration unit scheduled to commence within food factories by fiscal year 2026.
Cosmo Energy Holdings has emphasized that “existing technologies are sufficient for implementation” (New Energy Business Division). With commercialization agreements already underway with food and beverage manufacturers, the company is targeting commercial deployment as early as fiscal year 2027, with applications extending to automotive fuels and other sectors.
This collaboration underscores both companies’ commitment to advancing sustainable energy solutions and contributing to a circular economy by transforming food processing residues into renewable fuel.

Natural Capital Technology make the Circular Economy the norm
Toward a sustainable and scalable circular society
Rather than depending on single-product sales, S-Bridges is building a platform business chain from farmland to market. with diversified revenue streams by redesigning the value. By integrating farmland, materials, equipment, data, and intellectual property, We are creating a circular business model that generates multiple sources of value.
This ecosystem embodies the circular economy not merely as an ideal, but as a system that can be implemented, operated, and scaled. We design the circular flow connecting farmland, manufacturing, data optimization. and consumers, and provide a platform that generates revenue through AI-powered
By integrating data across the biomass generated on farmland, production processes, material creation, and distribution, We are building a Digital Twin model that enables visualization and optimization through data. This transforms agriculture from a primary industry into a data-driven resource industry.
Optimizing production efficiency
Maximizing resource utilization
Visualizing environmental impact
Creating new materials and new value
Maximizing Revenue with “Use-It-All” Green Tech
Maximizing land-use efficiency
We eliminate waste, cut CO₂ emissions, and create circular resource flows. Nature Positive is not a concept - it is how our business is built.
We are committed to maximizing revenue per unit area of farmland.
We are working to create new GreenTech industries rooted in local resources.
We view intellectual property as a key strategy for turning GreenTech innovations technologies. Demonstrating business scalability and expansion into scalable industries, rather than leaving them as stand-alone to support this vision, we are strategically filing IP in areas such as proprietary equipment, biomass processing, material generation, and data-driven utilization methods.
Global Business Expansion
By building implementable models for circular industries, we are expanding this approach around the world.
