From Waste to Fuel
Used cooking oil is refined through a process called transesterification to create biodiesel, a cleaner-burning alternative to petroleum diesel.
Environmental Impact
Recycling UCO prevents it from clogging drains and polluting waterways. Biodiesel also reduces greenhouse gas emissions by up to 85% compared to conventional diesel.
Benefit for Restaurants
Restaurants can turn a waste management cost into a revenue stream by selling their used cooking oil on ONE ECO Loop, improving both their bottom line and sustainability credentials.
How Biodiesel is Made
The chemical process of creating biodiesel involves reacting used cooking oil with an alcohol (like methanol) and a catalyst, which separates the glycerin and produces methyl esters (biodiesel).
UCO and Water Quality
Improper disposal of used cooking oil can lead to severe water pollution. One liter of oil can contaminate up to one million liters of water. Recycling prevents this damage.
Creating Green Jobs
The collection, processing, and distribution of used cooking oil for biodiesel production creates jobs in the green economy, supporting local communities.
