Food waste to fuel the future

COP26 and its alarming reports on global warming have placed corporate sustainability high on the agenda, and businesses are looking for ways to support the UK’s pledges to fight climate change. As businesses grapple with the urgent need to support the collective fight against climate change, there’s no part of operations that can be ignored.


Companies that deal with food and drinks can help reach Net Zero targets by reducing their waste. Reduced portion sizes and reduced packaging are obvious targets but arranging to have food waste collected and recycled by a waste management company comes with a series of benefits.


At Warrens Group, we collect food waste and take it to our state-of-the-art anaerobic digestion facility. The process of anaerobic digestion is much simpler than the name suggests. Food waste is broken down and converted into clean, green energy. The potential of the food waste recycling is huge, and one that will prove crucial to the UK’s fight against climate change.


How is anaerobic digestion helping in the fight against climate change?


Providing electricity

The energy created in the anaerobic digestion process can provide electricity and heat for homes up and down the country. It is a sustainable alternative that many will be turning to as legislation cracks down on the use of fossil fuels. While food waste should be kept to minimum wherever possible, anaerobic digestion is a sustainable way to create renewable energy from unavoidable food waste.


Saying goodbye to grey fuel vehicles

One of the main focuses in the fight against climate change is the aim to reduce the amount of petrol vehicles on the road. The anaerobic digestion process creates clean energy that can power vehicles. New conventional petrol and diesel cars and vans will be banned from sale in the UK from 2030, which will see a greater push for alternative fuel sources in the coming years.

Many of the trucks in our fleet are powered from the waste they collect.


Reducing landfill

Anaerobic digestion and the collection process help reduce landfill and prompts businesses to closely monitor their food waste supplies. As the Warrens fleet collect food waste and take it to the anaerobic digestion plant, businesses up and down the country are forced to keep a close eye the amount of food waste that is produced, which helps reduce unnecessary food waste.


By learning more about the process of anaerobic digestion in the UK, businesses and individuals can help the UKs fight against climate change.
