Collecting and Filtering Grease
In terms of grease just about every restaurant or institution with an kitchen (school, prison, retirement home, etc...) has waste grease they are disposing of. It would make sense to start inquiring in your local area for what is available. Many people even start collecting from a few restaurants and filtering grease before they get a vehicle and convert it to see just how difficult it is to find grease in their area. The best way to start is by purchasing a DVD put out by Golden Fuel Systems called Liquid Gold. It is all about collecting and filtering grease and it is available here .
