It is best to compost small amounts of grease scraped from traps and cookware (in a paper milk or ice cream carton). The grease from traps and cookware should not go into the used oil recycle storage bin. Brown grease should not be mixed with yellow grease, unless the yellow grease hauler can recycle the entire contents when they are mixed. Large quantities of brown grease should be disposed of through a local cooking oil and grease recycler.
