Greenhouses – Closing the loop in controlled agriculture

Greenhouse operations are highly controlled agricultural systems with continuous demand for:

  • heat

  • growing substrates

  • water and nutrient efficiency

  • waste management solutions

At the same time, they generate significant amounts of organic residues, making them ideal environments for integrated pyrolysis systems.

The role of biochar in greenhouse systems

In horticulture, growing substrates are critical for plant health and productivity.

Currently, many systems rely on:

  • peat-based substrates

  • coconut coir

  • mineral wool or synthetic media

However:

  • peat extraction is environmentally problematic and increasingly regulated

  • alternative substrates are often costly or limited in availability

Biochar as a substrate component

Biochar can be used as:

A partial or full replacement for peat in substrate blends

Key properties in greenhouse applications:

  • high water retention capacity

  • improved aeration and root development

  • nutrient buffering and retention

  • stable structure over long periods

This supports:

  • healthier plant growth

  • reduced irrigation demand

  • improved nutrient efficiency

Heat integration – a key operational factor

Greenhouses require continuous heating, especially in colder climates.

Satoumi systems provide:

Recoverable process heat as a byproduct

Typical use cases:

  • climate control and temperature regulation

  • soil and substrate warming

  • drying of plant residues

  • integration into existing heating systems

This can reduce:

  • fossil fuel consumption

  • energy costs

  • dependency on external energy supply

Closing the loop on biomass

Greenhouse operations generate organic waste streams such as:

  • plant residues

  • pruning waste

  • rejected biomass

  • substrate residues

Satoumi enables:

On-site conversion of this biomass into usable outputs

This creates a circular flow:

  • waste → biochar (substrate input)

  • waste → heat (energy supply)

Operational advantages

  • reduced waste disposal costs

  • lower substrate purchasing costs

  • improved resource efficiency

  • reduced external dependencies

  • better control over input quality

Water and nutrient management

Biochar improves:

  • water retention within substrates

  • nutrient availability and buffering

  • reduced nutrient loss through leaching

This is particularly important in:

  • high-intensity greenhouse production

  • regions with water scarcity

  • systems with strict nutrient management requirements

Economic implications

Greenhouse operators can benefit from:

  • reduced heating costs

  • lower substrate expenses

  • decreased waste handling costs

  • improved yield stability

In many cases, heat utilization alone can represent:

A significant share of the economic value

The Satoumi advantage

Satoumi systems enable:

  • compact, decentralized integration into greenhouse environments

  • simultaneous production of heat and substrate material

  • adaptation to available biomass streams

  • scalable deployment depending on operation size

Strategic relevance

Greenhouse agriculture is evolving toward:

  • higher efficiency

  • reduced environmental impact

  • circular resource use

Satoumi supports this transition by:

Linking energy, materials, and waste into a single system

In this context, greenhouses move from linear input-output systems

to integrated, self-sustaining production environments.

Interested in becoming an early partner?

Satoumi is currently seeking pilot partners to realize the first projects and move the technology into real-world deployment.

At this stage, we are primarily looking for organizations capable of participating in early implementation, prototyping, manufacturing, or operational pilot projects.

If your organization is interested — even if the timing is not yet ideal — we encourage you to contact us.

We are happy to:

  • provide additional technical information

  • discuss potential collaboration models

  • evaluate whether a partnership is a good fit

  • place interested organizations on our early partner and deployment waitlist

We are also working toward making complete reactor systems available in the future through manufacturing and deployment partners.

If you are interested in:

  • future reactor purchases

  • licensing opportunities

  • pilot deployments

  • or future rental/leasing models

we would be glad to stay in contact and reach out once the appropriate deployment stage is reached.
