Driving Positive Impact Innovation — Together

At Satoumi, we are not only developing novel technologies—we are also shaping new industries. Every application you see here will be pioneered and continuously refined by us. Through our international licensing model, partners can integrate these solutions directly into their own operations, creating new revenue streams and measurable climate benefits.

At the same time, we operate selected projects ourselves to continuously improve our systems, validate performance, and explore new opportunities.
Crucially, we do not compete with our license partners: We deliberately focus our own activities on global niches and markets that are not served by our licensees.

This approach is fundamentally different from traditional start-ups.

Instead of concentrating on market domination, we aim to spread positive-impact innovations as widely as possible— transforming challenges into opportunities and ensuring that technology serves the planet as much as it serves the economy.

By supporting Satoumi early, customers and investors become part of a global movement that combines profitable growth with lasting ecological impact.

Mobile Pyrolysis Container

Our pyrolysis reactor is integrated into a standard shipping container, which allows it to be transported almost anywhere by road, rail, or cargo ship. The energy required for operation is drawn primarily from the biomass itself, using the syngas (the combustible gas fraction produced during pyrolysis).

Instead of transporting large amounts of biomass to a central facility, pyrolysis can be carried out directly on site. This saves significant fuel, reduces logistics costs, and makes the service accessible to more customers. The decentralized design also enables serial production of pyrolysis containers and global deployment, allowing for the level of scalability required to achieve a truly positive impact

Bio-Waste Utilization

Many biomass streams cannot be effectively recycled or are generated in quantities too large for conventional processing to be economical. Through pyrolysis, these residues can not only be safely and quickly treated, but also converted into valuable biochar. At the same time, the carbon contained in the biomass is stabilized for centuries, rather than being released back into the atmosphere as CO₂ through composting, digestion, or open burning.

Biomass feedstocks we will test for Pyrolysis suitability:

  • Wood and forestry residues (deadwood)

  • Agricultural plant residues

  • Brewery and biogas fermentation residues

  • Food waste and spent coffee grounds

  • Animal manure

  • Green-space maintenance clippings

  • Paper and cardboard

  • Macroalgae

  • Biodegradable plastics

  • Invasive plant species

Biochar – Plant-Based Carbon with Many Applications

Biochar (biological charcoal/plant carbon) consists largely of stable carbon compounds. Beyond numerous other applications, biochar can increase agricultural yields. Its highly porous structure creates an enormous internal surface area that stores water and nutrients like a sponge, while making them available to plant roots and beneficial microbes. On farmland, biochar functions as a reservoir for water, nutrients, and microorganisms. This reduces fertilizer requirements, lowers nitrate leaching into groundwater, and improves soil resilience to heat waves and droughts.

Other key applications include:

  • Growth medium in horticulture (peat substitute)

  • Use in desert greening and land restoration projects

  • Water filtration

  • Animal feed additive

  • Reducing cement demand in construction (CO₂ savings, as concrete is the world’s second-most-used material after water)

  • Carrier material for catalysts in the chemical industry

Seaweed – Biomass of the Future

Seaweed (macroalgae) is among the fastest-growing biomasses on Earth. Seaweed farms can be sustainably cultivated on the largely unused ocean surface, suspended on ropes and buoys, without disturbing the seafloor. Seaweed is rich in proteins and produces alginates, a key raw material for next-generation biodegradable plastics. It also absorbs CO₂ significantly faster than trees.

Satoumi is developing processing systems to unlock the full potential of this sustainable resource. Residual algae are refined into biochar in our own pyrolysis units, permanently binding their captured CO₂ in a stable form.

Advantages of seaweed farming include:

  • No need for arable land (utilizes the untapped ocean surface)

  • No freshwater consumption

  • No fertilizers or pesticides required

  • Production of three essential raw materials with minimal resource input

  • Creation of new income opportunities for fishers in times of overfishing

  • Contribution to the reduction of ocean acidification—the twin crisis of global warming

Sustainable Proteins

The future of global nutrition requires new, sustainable protein sources. Plant-based proteins are key, but conventional crops such as soy demand vast farmland and freshwater. Protein extraction from seaweed offers a resource-efficient alternative.

Because Satoumi extracts proteins before pyrolysis, valuable food resources are not lost to energy production. Seaweed proteins also hold promise for animal feed, for example in aquaculture. Over time, seaweed-derived proteins can be broken down into their amino acids for use in a variety of biochemical applications. These plant-based amino acids could even be converted into animal-equivalent proteins using biotechnological processes with recombinant microorganisms. Satoumi plans to pursue such innovations once the company is firmly established.

Through this integrated approach, Satoumi ensures that every component of sustainable biomass is used optimally, creating measurable positive impacts for both environment and economy.

Biodegradable Plastics

After protein extraction, alginates are recovered from seaweed. Already used in cosmetics and medical technology, alginates have great potential for truly biodegradable plastics. Unlike many current bioplastics, alginates break down completely because they are natural substances readily decomposed by microorganisms.

At present, alginates remain relatively costly due to limited industrial production. Satoumi applies its mobile container concept here as well: we plan to house extraction and pyrolysis systems in shipping containers, enabling decentralized and scalable alginate production directly at seaweed farms.

CO2 Certificates

A key pillar of Satoumi’s model is the generation of high-quality CO₂ certificates. These help finance ongoing research and support the scaling of sustainable technologies. Having followed carbon markets for years, we are aware of the challenges: many existing offset projects show deficiencies in quantification, overlook side effects, or fail to guarantee long-term carbon storage. Satoumi takes a science-based approach to ensure valid and permanent carbon sequestration, guided by these principles:

  • Quantifiability:
    The exact amount of CO₂ stored in biochar can be precisely calculated, accounting for production emissions and minor microbial decomposition during the first years in soil.

  • Additionality:
    Without the financing provided by CO₂ certificates, the rapid scaling of operations, expansion of seaweed cultivation, and further R&D on new sustainability applications would not be feasible at the necessary speed.

  • No competition with other uses:
    By processing biomass at the end of its usable life and after valuable proteins and alginates have been extracted, we ensure that no resource is diverted from a more beneficial purpose.

  • Long-term stability:
    While trees eventually decay and release CO₂, biochar remains stable for centuries—as demonstrated by ancient Terra Preta soils in the Amazon.
