Delivering Circular Outcomes

C-Loop provides the ultimate solution for organic waste produced from agriculture by recognising and unlocking its nutrient-rich value as a resource. By optimising how organic waste is valued, we provide long term contracts to suppliers of this resource to underpin our projects.

C-Loop recognises the value of managing organic waste onsite. Our patented processes see our biorefineries lower carbon emissions and produce low-cost, organic, and carbon-neutral algae-based food colours, plus reliable baseload energy year-round. C-Loop removes the burden of doing this alone, delivering and managing the operations of each project. This enables businesses to sustainably transition without the additional cost.

By optimising bioenergy projects through our patented processes, C-Loop creates circular outcomes that create multiple product streams from each project. By processing every byproduct, nothing goes to waste, building lasting economic and environmental value.
Biorefineries at a Glance
C-Loop converts organic waste into high-value, natural and organic food colours, renewable energy, and useful co-products through our innovative biorefinery process. Using anaerobic digestion, our facilities process agricultural waste into biogas for clean energy, while simultaneously producing key precursors that enable us to deliver carbon-neutral food colours and nutrient-rich fertiliser to improve soil health.
By closing the loop on organic waste, we build a circular economy that supports farmers, manufacturers, and the environment through lower emissions, steady revenue streams, and sustainable agricultural practices.
