C-Loop Biorefineries
Our biorefineries deliver sustainable solutions for waste management and renewable energy.
Linear Bioenergy
Most bioenergy plants operate a linear model focussed on energy generation as a way of managing waste. Whilst good in theory, this model creates additional challenges to manage and doesn't enable the full potential of the bioenergy process to be realised.
This approach leads to sustainability outcomes which are commercially reliant upon government schemes and limited sources of revenue to remain viable.
When looking at bioenergy this narrowly, we miss the bigger picture. Valuable by-products from the process - like biogenic CO₂, renewable heat, and nutrient-rich digestate- have value to markets globally!
In other words, the process outputs are under-utilised.
C-Loop's Biorefineries
C-Loop biorefineries capture full value from every output, creating circular outcomes that benefit multiple stakeholders without adding a green premium.
The process
Organic waste from our agricultural partners is continuously fermented using anaerobic digestion in the biodigester. This produces two main outputs:
Digestate: A nutrient-rich, semi-solid mixture.
Biogas: A methane-rich gas stream.
Micro algae cultivation from digestate
Liquid nutrients, Co₂ produced on site and residual heat from energy production flow into biosecure raceway ponds to cultivate micro algae, supplying the global natural food colour market. The remaining solid digestate is processed into a nutrient-rich agricultural fertiliser.
Biogas utilisation
Biogas is processed into two clear products:
Food-Grade CO₂: Sustainably captured for food and beverage applications.
Biomethane: Either ready for grid injection or combusted to generate reliable baseload electricity and renewable heat for industrial users. Any excess electricity goes straight back to the local grid during peak demand.
By meeting the demands of multiple industries from a single location, C-Loop eliminates the green premium, ensuring consumers do not pay extra for sustainable outcomes.
