Most kitchen exhaust systems are inspected monthly or quarterly and require a system cleaning due to grease build-up. On average an exhaust system cleaning uses approximately 350 gallons of water along with toxic chemicals necessary to remove grease from the system. In addition the metal baffle filters are generally cleaned nightly, requiring labor, water and toxic cleaning chemicals.

before they enter the exhaust system
Elemental Impact Partner Ellis Fibre (EF) manufactures a patented, disposable grease filter that is placed in front of the baffle filters. EF's Grease Lock Filters (GLF) collect 90% plus of the kitchen grease particulates before entering the kitchen exhaust system. By eliminating grease build-up in the system, the nightly baffle filter cleaning is generally reduced to weekly; the number of third party contracted kitchen exhaust system cleanings are significantly reduced.

Each of the pilot restaurants realized a cost-savings by installing the GLF system and chose to continue using the filters post pilot. Cost-savings were derived from reduced labor hours, fewer third party contracted cleanings, and reduced water usage and sewage treatment charges. The big winner is the local community who benefits from lower commercial water demand and a reduction in toxic chemicals entering the sewer system and|or waterways.

As a Sustainable Food Court Initiative Atlanta Airport Pilot team member, Ei Partner HMSHost agreed for Pei Wei, located in the International Terminal, to participate in the pilot. Working closely with the HMSHost team, Kyle Mastin - airport concessionaire manager - was impressed with the GLF pilot results at Pei Wei.
At an Ei | Atlanta Airport meeting last week, Kyle showcased the pilot success with enthusiasm for broader use at the airport. The ZWA Blog post, GREASE: Activating the Zero Waste Evolution, introduces the GREASE task force and mentions the airport's interest in assessing the grease generated at the terminal concessionaires along with potential on-site energy options.

As a proactive solution to AKG, Ei intends to support the widespread use of the GLF in commercial kitchens with a three-tier approach:
- Installation of GLF systems - goal is to establish a metrics tracking system to quantify the economic and environmental impact for the foodservice operator and the community at-large.
- Certification of filter compostability - filters are made of lambs wool with no metal; EF intends to pursue the ASTM Standards testing required by BPI in their compostable packaging certification program.
- Utilization of grease captured in filters - grease is valuable in waste to energy technologies; determine how to best use the grease captured in the filters, whether extracted or within the filters.
GREASE is entering a new industry frontier with Ei leading the charge. Stay tuned as Ei determines the economic benefits, substantiates the environmental stewardship and develops an industry-wide action plan for kitchen exhaust system grease. EXCITING TIMES, indeed!
