Once funding is secured, the Ei Airborne Kitchen Grease Initiative moves forward with the following stages: Prior to embarking on a city-wide AKG template, integrity within the proactive AKG approach must be substantiated. Initial action steps fall into four categories:
  1. Fire Safety
  2. Cost-Savings
  3. Metrics Platform
  4. Filter End-of-Life

Beginning in early 2013, Ei began substantiating the four categories in the AKG Stage 1, Building the Foundation.

Fire Safety:

First and foremost is fire safety. Certified to UL Standard 1046, GLF will not support combustion. Grease collected on the filter may flare-off if excessively heated or subjected to flames; however, when the flame source is removed the filter will self-extinguish and is replaced with a new filter.

GLF is tested, compliant and | or recognized by the following:
  • Standard UL 1046 | ULC-S649 & UL 710 - Flame Exposure & Abnormal Flare-Up Test
  • NFPA 96 | IFC - Ventilation Control & Fire Protection of Commercial Cooking Operations
  • NSF 2 | ANSI 51 - Food Equipment & Materials-Formulation Review (Sanitation|Toxicology)
  • TYCO - World Leader In Fire Suppression Systems
  • IMC | UMC - Protects Public Health & Safety For All Building Ventilation Design

Cost Savings:

To substantiate and quantify the water, labor and toxic chemical savings, Ei joined forces with Compliance Solutions International (CSI) for a three-restaurant, eight-week GLF system pilot. The Cost Savings in Commercial Kitchens By Using Grease Lock Filters, A Report on Restaurant Pilots prepared by Jay Parikh, CSI president is downloadable below:

The independent comprehensive report documents the impressive water, chemical and labor savings experienced by the participating restaurants. In each case, the restaurant’s bottom line improved by using GLF due to reduced cleaning of the baffle filters and the entire KES.

In addition to the documented labor, water and chemical savings in the report, the facility experiences reduced fire risk and repairs & maintenance due to less grease accumulation within the exhaust system and the roof ventilation area. In addition to savings documented in the Summary section, the community benefits from reduced emissions due to fewer full-exhaust system cleanings by a third party.

Metrics Platform:

Program success is substantiated by quantifiable data. For the AKG Initiative, measurable success is multi-faceted for the foodservice operator, building owner and the community.

The foodservice operator experiences cost-savings from reduced third party full-system cleanings, labor for baffle filter cleaning, and water usage. Easily quantified, a metrics collection platform that calculates and presents the savings in a simple format for the operator is under development, beginning with the foodservice operator focus. Ei Partner HMSHost – Charlotte Airport serves as the metrics platform beta test.

In addition to single-operator reports, the platform aggregates savings by companies, territories or where ever other filters are added to the system. Community-wide water savings, toxic cleaning agent use reduction, roof repair & maintenance savings, improved air quality and reduced carbon emissions will integrate into the metrics platform. As the Ei AKG Initiative progresses with the city-wide template development, savings associated with participants will incorporate into the platform.

Filter End of Life:

Ei Strategic Ally The Institute for Local Self-Reliance is working on an appropriate compostability test for the filters. Current U.S. industry standards | certifications for compostability are designed for foodservice packaging, not filters made primarily of sheep's wool. New Zealand officials issued a letter substantiating the filter compostability.
