The levy on plastic shopping bags doesn’t apply to a bag to keep raw meat separate from the rest of the food shop. Hospital gloves and syringes are “single use only” for good reason. Hygiene cannot be compromised.

The important next step is to deal properly with that waste. The best expression I’ve heard is “waste product”. The idea of treating waste the same way as you would market any product to get the best price, or in this case reduce the charge. The bring centre concept has been working well for farm plastics for many years now. It is certainly not cheap, but we are all learning that presenting waste clean and tidy reduces weight and cost.
