Cooking Oil Recycling Fuels Green Energy Revolution in the UK

As of October 2025, the UK is undergoing a remarkable green energy transformation, and the key driver behind this change is an unlikely hero - used cooking oil.

Just a few years ago, millions of litres of used cooking oil generated by businesses across the country were often simply poured down the drain, leading to the formation of troublesome "fatbergs". However, a combination of technological innovations and a nationwide shift in recycling mindset has given this former waste product a vital second life.

Today, under government mandates, all UK diesel now contains at least 7% biodiesel, meaning that millions of cars are partly powered by this renewable fuel. The benefits are twofold - replacing fossil fuels with biofuels reduces the amount of carbon dioxide being added to the environment, and if the biodiesel is produced from waste oils and fats, this reduction is around twice that gained from biodiesel made from crop oils.

As a result, waste-based biodiesel has become a critical component in meeting the UK's environmental targets. Used cooking oil, once considered a nuisance, now plays a central role in the country's green energy transition and is recognized in law.

To make this process seamless for businesses, companies like Olleco have developed innovative solutions, including an app that allows foodservice operators to easily manage their used oil collection and fresh oil delivery. This not only saves time and energy but also reduces the carbon footprint of the entire process.

Olleco's comprehensive service, combined with its nationwide presence and array of awards, has been instrumental in transforming the way the UK handles its used cooking oil. From kitchen leftovers to clean energy, this once-discarded resource is now a vital part of the country's circular economy, benefiting businesses, communities, and the planet.
