There are no proper facilities for waste cooking oil disposal or appropriate enforcement of regulations. Currently, used cooking oil is primarily disposed down drains, dumped on the ground or in landfills, or donated to market food vendors. Health problems arise from reusing cooking oil more than once. Improper disposal of used cooking oil results in the blockage of drains and sewers. In addition it contributes to the killing of terrestrial and aquatic plant and animal life, like a silent and invisible oil spill no one is aware of.
