An active grown by fermentation.
Growing the active in a fermenter sets the land use, the inputs, the energy load, the waste stream and the packaging. Each of those is stated below, with what we commit to as volumes grow.
- Production
- Fermentation
- Land use
- None
- Animal inputs
- None
- Biomass
- By-product streams
In practice
Land use, inputs, energy, waste, packaging.
Most of these follow from the production route itself and hold at any volume.
- Grown in liquid culture
- The active grows in a fermenter. No land-use change, no wild harvest, no monoculture footprint behind the supply chain.
- Defined inputs
- The yeast grows on a defined medium of sugars, salts and nitrogen sources. No animal-derived components, no rare botanical inputs to compete for.
- Energy and water
- Bench and pilot operations run on grid renewables where available, and process water is recycled in clean-in-place loops.
- End of life
- Spent yeast biomass is biodegradable and routed into agricultural by-product streams rather than to landfill.
- Packaging
- Recyclable glass primary packaging and FSC-certified secondary packaging on finished goods from launch.
- Output scales with tank volume
- Volume grows with fermenter capacity. Acreage, crop yield and harvest season are not part of the supply equation, so the footprint does not track demand.
