There are a number of environmental benefits from using biodiesel - particularly biodiesel made from by-products of other industries.

Pure Fuel's use of used cooking oil makes use of a waste which has few alternative uses. The use of biodiesel also helps consumers and businesses reduce their carbon footprint - the amount of carbon dioxide emitted as a result of energy used.

Pure Fuel's biodiesel production displaces carbon dioxide, one of the main gases responsible for global warming. This will contribute significantly to the government's predicted savings of 1 million tonnes of carbon dioxide a year (equivalent to taking 1 million cars off the road) to be achieved by requiring 5 per cent of all road fuels sold in the UK to come from renewable sources by 2010. 

The main point is that the ecological footprint from biodiesel of all types is more environmentally friendly than mineral diesel. And biodiesel from used cooking oil is better for the environment than biodiesel produced from virgin oils such as rapeseed oil. Taking into account all the energy used in producing biodiesel from used cooking oil and then adding the displacement of carbon dioxide, Pure Fuel's activity has a net positive effect on the environment.
