Just checked TWBC website and here's all they say about food waste: -
What happens to the collected food waste?
The food waste is taken to a local facility where it is composted using a natural process, which means it is safe to use as a soil improver on local farmers' fields. If you already compost at home, please continue to do so. You can use your food waste collections for any food that you do not want to compost yourself.
So what's the difference between composting at home, or composting on your allotment?
Answers on a Waitrose compostible bag, not to be confused with a similar-looking one from Twongos or Borrisons, Mazda or Widl (?), which won't compost for a hundred years or so, and will clog up the environment even more than it does now!
I can imagine all our hard-working farmers doing high kicks when a pile of that sort of stuff arrives to cheers from the environmentalists and happy bunnies prancing all around - with plastic in their teeth...
