Recovery

Living Fuels has achieved a major breakthrough in transferring energy from a renewable source into carbon neutral electricity – something that we are very proud of.

After Living Fuels collects used cooking oil from our various sites around the UK, it is taken to our state-of-the-art recovery facility. There the oil is pumped into settling tanks, where it is left for between two and five weeks so that gravity can take its course and all of the impurities in the oil collected during the cooking process can settle to the bottom and be removed. The lighter, purer oil is then put through the second stage of our process, filtration. Once this has been achieved, the used cooking oil has been fully recovered and reclassified as an ‘end of waste’ bioliquid. In fact, the oil is so clean that you could probably fry your chips in it again (but we don’t recommend it)!

Once recovered, LF100 is used either in our combined heat and power (CHP) units, to power UK homes and businesses through our emergency reserve contract with National Grid, or for use in sustainable oleochemical applications. Please visit the Power and REG Oleo pages for more information.

It is important to note that we are not a biodiesel company; LF100 is not used for road traffic fuel.

Unlike the manufacturing of biodiesel, which relies on chemicals in order to make the waste oil more viscous, we don’t add chemicals at any point throughout our recovery process and only ever heat the oil to an ambient temperature, to keep out the winter chill. This distinction has proven that our recovery process is the most sustainable when it comes to uses for waste cooking oil.
