MRC has been conducting parallel projects to investigate the use of Waste Vegetable Oil (WVO) and Coconut Oil (CNO) as substitutes for diesel oil. The usage and disposal of vegetable oil by large consumers, including hotels, fast food chains and hospitals was investigated. This study has shown that between 35-40% of oil is disposed of, and that the consumers of oil also have fleets of diesel vehicles. WVO can potentially be used as a substitute for diesel oil.
