Upmarket British supermarket chain Waitrose is already one of Earth’s greenest. It hasn’t put any food waste into landfills since 2012, and last year it introduced gluten-free pastas that reuse the leftover scraps for the packaging. Its latest eco-friendly move, though, takes aim at England’s food-waste problem — which continues to spiral out of control — by converting the scraps into fuel that powers its delivery trucks.
Per the U.K.’s Times,
Waitrose is teaming up with an alternative-fuel supplier to “become the
first company in Europe to use lorries which are run entirely on
biomethane gas generated from food waste.” Waitrose says these trucks
can travel up to 500 miles on that fuel type, which is essentially just
the by-product of rotting vegetable matter. The technology allows the
vehicles to run entirely on a source that’s 35 to 40 percent cheaper
than diesel and emits 70 percent less carbon dioxide. Many would argue
that’s reason enough for the switch, but it turns out trucks that run on
biomethane fuel are also quieter
than their noisy gas-guzzling counterparts, can be refueled faster, and
even get
better gas mileage. Waitrose’s supplier, CNG Fuels, estimates the savings on fuel alone should run between $18,000 and $25,000 a year per truck.
