Fiberglass grease interceptor offers university long-term solution for managing food waste

Problem: Michigan State University needed to replace deteriorating concrete grease interceptors. Their Snyder Phillips dining hall seats 600 and is one of the busiest on campus. Student food waste caused the interceptor system to plug, and it needed to be pumped out once or twice each week. 

Solution: ZCL | Xerxes replaced the 2,500-gallon concrete interceptor with a corrosion-resistant, 20,000-gallon fiberglass grease interceptor. The project manager realized the best design would have a side discharge pipe rather than an end discharge pipe to eliminate 90-degree elbows. This reduced the potential for food, solids and grease to plug up the system. 

Result: The university’s mechanical team now specifies only fiberglass grease interceptors. The new interceptor is pumped out once every several weeks instead of weekly. They haul away the waste to be burned as biofuel. 952-887-1890;
