Grease Interceptor is a plumbing device designed to intercept most greases and solids before they enter a wastewater disposal system. As a alternative to precast concrete or mild steel offerings, BIORECKAT Grease Interceptor was developed to provide an innovative solution to grease capture and retention. The result is a versatile, robust Fiberglass Reinforced Plastic grease interceptor that eliminates corrosion and rust problems associated with unlined concrete and metal systems.
