Sanctuary Friends Foundation of the Florida Keys has partnered with Marathon Biodiesel in an effort to reduce diesel use and greenhouse gas emissions in our fragile bay and ocean. The use of diesel in vehicles and vessels is a major contributor of carbon dioxide in the atmosphere, which scientists are convinced is a major element contributing to climate change and ocean acidification.
Marathon Biodiesel owner Jeff Lillie is a former commercial fisherman and has invested his life savings into this environmentally friendly business, which will have a symbiotic relationship for your restaurant and the environment.
Waste vegetable oil produced as a byproduct of frying food is cleaned locally to produce clean burning biodiesel. Tens of thousands of gallons of cooking oil is shipped into the Keys annually for cooking and then hauled out of the Keys by diesel burning trucks to be shipped overseas. There is demand in the Keys for biodiesel for use in local commercial fishing and charter boats, meaning the cooking oil used in the Keys will be turned into the clean burning biodiesel used in the Keys, and with your help, eliminating excess waste.
Anything we can do as residents and business owners living in one of the most environmentally sensitive ecosystems in the world to reduce our carbon footprint is a major contribution to our future. Partnering with SFFFK and Marathon BioDiesel is an easy way to help our fragile ecosystem.
By uniting with us, you will in turn get a valuable tax credit, since Marathon Biodiesel has the only ASTM Certified waste vegetable oil cleaning machine in South Florida. Participating restaurants will also be given a participation plaque to display, and recognition of your contribution posted on our website, Marathon BioDiesel’s website, and in our monthly newsletter - which will be valuable advertisement for your company.
Please call us at (305) 289-2288 for more information and to start on your journey to a healthier Florida Keys.
