Case Studies

Peterhouse College, Cambridge – Two Grease Guzzler's installed.

The Project
Founded in 1284, Peterhouse is the oldest College in the University of Cambridge and with approximately 250 undergraduates, 90 graduate students and 45 fellows it is also the smallest. The college catering service offers its services to generations of students as well as to various functions and parties taking place on the premises. On average, 100 – 200 lunches and up to 300 dinners are provided each day.

The Problem
Due to the long history of their “enviable reputation for the standards its food and wine”, Peterhouse College recognizes the importance of having a clean and hygienic catering environment within their onsite kitchens. The old architecture of the site provides problems with the drainage systems especially as there is a high turnover of food at lunch and dinner time. The high amount of oils, fats and other grease which result from cooking start settling in the drains causing blockages.

The Solution
The product used to solve the problem is WPL's Grease Guzzler. This product is an innovative, self contained grease management system designed for commercial catering facilities serving hot food and producing waste: Fat, Oils and Grease (FOG). The system utilizes patented bio-technology, ensuring efficient and effective drain cleansing with minimal impact on the environment.

The Grease Guzzler helps to prevent odour caused by rancid grease, increases hygiene and prevents drain blockage long term. Due to the minimal need of service attention the product is a ‘fit and forget' option.

The Grease Guzzler has been installed in two places to deal with the problem of blocked drains. Its main role is to ease and prevent blockage caused by grease. The college catering has previously used with grease traps before which need a lot of staff attention and costly service and appreciates the Grease Guzzler for being a ‘fit and forget' option which has to be serviced no more than twice a year. Through a small pump within the Grease Guzzler a daily dose of biofluid (S65) is flushed into the drains. The biofluid comprises 58 different types of bacteria which work day and night at breaking down and digesting the edible food particles that cause the drain blockage.   Keith Stock, Clerk of Works commented,

“A healthy, hygienic environment is one of our top priorities and WPL's Grease Guzzler was chosen to reduce the inevitable contamination in our drains, without impacting on the environment or catering staff's time.  We have one unit installed already, which is fulfilling our expectations, and have ordered a second to manage grease in our kitchen.”
