Marmite Renewable Energy

Love It or Hate It

Marmite is Generating Renewable Energy

We know that Marmite is an acquired taste, but at our original UK factory, micro-organisms are lapping it up in the name of renewable energy!

Every year, thousands of tonnes of solid Marmite residue is left in factory equipment. With no use for this waste, it would normally end up in landfill, contributing to the growing concern of climate change.

Climate change is one of the biggest threats to our planet, and an increase of more than 2 degrees in the earth’s temperature could have a serious and devastating impact on livelihoods worldwide.

Marmite want to do their bit to tackle climate change and help the environment, which is why the Marmite factory in Burton, United Kingdom, has taken some seriously positive steps and put their waste to good use. For the past five years, instead of Marmite waste going to landfill, it now goes into an ‘anaerobic digester’ - essentially a big composter. In this sealed vessel, micro-organisms are able to degrade the waste. In other words, they go nuts for it! As they thrive and reproduce, while getting their fill of tasty Marmite, the microbes release methane and carbon dioxide, which forms biogas that can be stored, burned in a boiler, or burned in a combined heat and power engine (connected to a generator).

Marmite is quite simply turning waste into energy! This simple yet ingenious solution has already generated 50% of the onsite gas usage – enough to power 1000 homes! Not only is it energy-saving, but all the remaining electricity used on site comes from renewable energy sources too.

At Unilever, when it comes to creating a bright future, we want to go strong and far. That’s why we’ve committed to becoming ‘carbon positive’ by 2030. That means 100% of our energy will come from renewable sources. With our partners, we will work to generate renewable energy.

It’s the first time we’ve put a deadline in place for this type of commitment and Marmite is just one of many of our brands working to create a bright future through innovative, energy-saving solutions. Ben and Jerry’s is turning waste into biogas, while our water reduced concentrated laundry liquid now comes in eco packs that can be used to refill existing bottles.

But we can’t do it alone. We want everyone to play a role! From the suppliers we use and the factories we operate, to the 2 billion people who rely on our brands every day. To find out more ways Unilever is helping to overcome climate change and see how you can get involved, click here.
