The Benefits of Working With Us
Grease Management Systems

Grease Traps
A grease trap is a device designed to intercept Fats, Oils, and Grease (FOG) from wastewater before it enters the drainage system. The trap captures the FOG, allowing clean water to flow through while preventing blockages and system damage.
With a wide variety of suppliers and manufacturers offering different solutions, we take a solutions-led approach. We remain manufacturer-agnostic to ensure we provide the most effective solution tailored to your specific needs, rather than offering a one-size-fits-all approach.

Grease Recovery Units
Grease Recovery Units (GRUs) are an advanced alternative to traditional grease traps. While they still separate grease from wastewater, GRUs take it a step further by actively recovering the grease, making them a highly efficient solution for larger commercial kitchens. The recovered grease can be sold for recycling, such as conversion into biodiesel, providing an environmentally friendly and cost-effective option.
Operating automatically, GRUs require less frequent maintenance than passive grease traps, making them a more convenient and long-term solution. With several brands and models available, we work with you to select the best GRU tailored to your kitchen’s needs. Our sister company, Filta, offers the market-leading FiltaCyclone unit, designed to maximise grease recovery, reduce energy usage, and provide a low-maintenance solution for commercial kitchens.

Bio Dosing Systems
Biological dosing systems use micronutrients, delivered through a peristaltic pump, to help prevent grease and fat build-up in your drainage system. By introducing indigenous microbes, these systems break down fats, oils, and grease (FOG), ensuring that your drainage system remains clear and efficient.
