According to a report in yesterday’s Times waste from the production of Marmite (itself the product of waste from the brewing industry) is now to be used to produce electricity by being fed to bugs who will turn it into methane.
The same article also tells us Pepsico sells 28,000 tonnes of oak husks left over from the making of Quaker porridge as fuel for power stations.
Other 'fancy thats' I came across while googling this topic:
People in Britain eat over half of the world's yeast extract
In 2010 there was a special Marmite chocolate on sale for Christmas - that one passed me by completely. I wonder what sales were like.
The video which promises to show Marmite production does nothing of the sort - perhaps the sight of all that brown sludgy stuff was considered too off-putting. It just shows bottles being labelled & put into boxes by a production line worker. Reminds me of my summer spent in the Boots factory - another one of those lessons in why it really is worth buckling down to pass exams, even though you might risk being labelled an unmarriageable bluestocking.
