British Supermarket to Power Itself Solely With Food Waste

Business

It's good to refrain from wasting energy, but it's even better to procure energy from items that you otherwise would waste.

That's the thinking behind the latest announcement from Sainsbury's, the second largest chain of supermarkets in the United Kingdom. The chain's Cannock location will soon be powered solely by the company's own food waste. Waste management and recycling firm Biffa has partnered with the store to use its advanced anaerobic digestion (AD) facilities and a power link that allows the Cannock store to use the waste generated from Sainsbury's other locations.

"This groundbreaking project helps to close the loop on food recycling and [allows] Sainsbury’s to continue to send zero operational waste to landfills," reads the chain's announcement.

Biffa trucks pick up Sainsbury's food waste to take it to its AD plant. From there, large silos break down the waste in a process Sainsbury's compares to the human stomach. The gas generates electricity, which supplies the Cannock store through a nine-mile cable. Any surplus energy returns to the national electricity grid.

Sainsbury's is already the UK's largest AD user, generating enough energy to power 2,500 homes.

Despite the company's plan, energy is not its first choice for using the company's food waste. The AD process only comes into play if certain foods are not purchased and thereafter deemed unsuitable for charitable donations or the creation of animal feed.

In France, chain Intermarché has announced a humorous initiative to take advantage of fruits and vegetables that would otherwise be wasted. Meanwhile, Chicago café Sandwich Me In makes use of every bit of waste it generates.

Under the guise of responding to consumer complaints that today's energy- and water-efficient dishwashers take too long, the Department of Energy has proposed creating a new class of dishwashers that wouldn't be subject to any water or energy efficiency standards at all. The move would not only undermine three decades of progress for consumers and the environment, it is based on serious distortions of fact regarding today's dishwashers.

If you have oak trees in your neighborhood, perhaps you've noticed that some years the ground is carpeted with their acorns, and some years there are hardly any. Biologists call this pattern, in which all the oak trees for miles around make either lots of acorns or almost none, "masting."
