Unilever has long stood proud as a food manufacturer with lofty sustainability goals—from their adoption of sustainable palm oil to their efforts urging consumers to cut back on waste, stating that food is “too cheap” in the developed world. Now the food giant has announced that they have saved over one million tonnes of C02 since 2008, using—among many other things—Marmite. Yes, that the sticky residue left over from manufacturing the Brit’s ‘love it or loathe it’ spreadable yeast extract is being fed into a waste-to-energy anaerobic digester to generate power to make—you guessed it—Marmite.
