Cooking waste is not something anybody likes to dwell on, but in an ambitious multi-million dollar deal announced by the renewable energy company 2OC and Thames Water, grease, oil, and fat from thousands of London restaurants and food companies will live out a second life as fuel for a power station. By 2015,Â Beckton, in East London, is slated to become the worldâ€™s largest fat-fuelled power station, capable of producing 130 gigawatt hours of renewable electricity, or enough energy to run 39,000 average-sized homes. Fat poured down the drain creates fatbergs â€“ who knew? â€“ which cause blockages and cost taxpayers upwards of a million and a half dollars per month to clear. Rather than dumping all that waste down the drain or into landfills, the sustainable initiative will collect thirty tons of waste per day – more than half the fuel the plant needs to operate daily. The rest will come from waste vegetable oil and animal fats.Â The concept could prove a windfall for creating a more sustainable food system, ensuring that food waste is dealt with in an innovative and appropriate manner. As Chief Executive Officer of 2OC, Andrew Mercer, explains, â€œOur renewable power and heat from waste oils and fats is fully sustainable. When Thames doesnâ€™t need our output, it will be made available to the grid meaning that power will be sourced, generated and used in London by Londoners.” Itâ€™s like grandma always said: waste not, want not.
