What are the current waste disposal methods for used cooking oil?
Currently, some restaurants are required to collect the grease in traps and pay to have it hauled off by a renderer. Some of the grease is used to supplement feed for farms; however, a lot ends up in landfills. Where grease traps are not required, restaurants and cafes may dump their used cooking oil down the drain where it often causes build-ups and blockages in municipal sewer pipes.
