What is Biofuel?
Source:UCO
Biodiesel refers to a vegetable oil - or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, ethyl, or propyl) esters. Biodiesel is typically made by chemically reacting lipids (e.g., vegetable oil, soybean oil, animal fat (tallow)) with an alcohol producing fatty acid esters.

Blends of biodiesel and conventional hydrocarbon-based diesel are products most commonly distributed for use in the retail diesel fuel marketplace. Much of the world uses a system known as the "B" factor to state the amount of biodiesel in any fuel mix:
100% biodiesel is referred to as B100
20% biodiesel, 80% petrodiesel is labeled B20[1]
5% biodiesel, 95% petrodiesel is labeled B5
2% biodiesel, 98% petrodiesel is labeled B2

Biodiesel works in the same way as normal diesel which you buy at the pump – in fact the diesel which you buy at the pump will probably have at least 5% biodiesel mixed in Using biodiesel made from Waste Vegetable Oils is one of the greenest ways to power your diesel engines as you are using a fuel made from waste. Proper Oils refines 100% of the biodiesel produced from the Waste Vegetable Oil which we collect.

What are the benefits of using Biofuel?
Minimize your Carbon emissions – as your fuel is made from “waste” oil.
Reduces harmful emissions which improves air quality.
As Proper Oils refines the Used Oil into fuel locally, the carbon savings are maximised.

How does it work?
The Used Cooking Oil (UCO) is refined into biodiesel by a process called trans-esterification – which changes the molecular structure so that it behaves like mineral diesel refined from hydrocarbon oils. To use biodiesel, you do NOT need to modify your vehicle – you use it as you would use normal diesel fuel.

Who is using it?
Richmond Council run the majority of their fleet on 100% biodiesel made exclusively from Used Cooking Oil – Proper Oils is a named supplier of biodiesel to the council.
