REFERENCE PROJECTS
High FOG wastewater into energy.
Our team built and operated anaerobic plants that turn food processing effluent high in fats, oils and grease (FOG) into biogas and clean water, and we continue to support them technically today.
REFERENCE PROJECTS
Two plants, two demanding effluents.
Energie des Mascareignes (EDM)
Mauritius
A waste-to-value plant treating high-strength, fat-rich effluent from tuna processing. Anaerobic digestion converts the organic load into biogas that replaces fossil fuel in industrial processes, followed by biological treatment, including nitrogen removal, to meet discharge requirements. Our team engineered, built and operated the plant while at Green Create, and Cirvanta continues to provide technical support.

Worcester
Western Cape, South Africa
An anaerobic treatment plant for effluent from poultry processing. The plant produces biogas, electricity and heat, returns clean water and reduces the load on municipal wastewater infrastructure. Our team engineered, built and operated it while at Green Create, and Cirvanta continues to provide technical support.

WHY FATS, OILS AND GREASE ARE DIFFICULT
High energy, high risk, unless the plant is designed for it.
Foaming and scum
Fats, oils and grease float, form scum layers and drive foaming that can block gas lines and take digesters offline. Pre-treatment and digester design must keep them under control.
Fatty acid inhibition
As fats break down they release long-chain fatty acids, which inhibit methane-forming bacteria if loading is not managed. Stable feeding and good monitoring are essential.
Variable, high-strength flows
Production-driven effluent swings in flow and strength. Buffering, robust process control and biological polishing keep the plant stable and compliant.
HOW WE HELP
From design to compliant, stable operation.
Process Engineering (FEL 0–3)
Feasibility, process design and detailed engineering for anaerobic and biological treatment of high-strength industrial wastewater, including fat removal and biogas use.
Owner’s engineering
Independent technical oversight for industrial owners, developers and investors, from technology selection through construction and commissioning.
Operations support
Troubleshooting, process and biological monitoring and remediation strategies that restore reliable performance and regulatory compliance.
