Switch to reusable bowl covers to give up aluminium foil or clingfilm, to cover food. Aluminium foil is not as bad, but it’s wasteful and expensive. But clingfilm is another thing entirely. This unique type of plastic wrap is very polluting to make, and it’s one of the few plastics at the supermarket bins that you are not allowed to recycle (most now accept plastic food wrap). It also is linked to many health issues.
Reusable bowl covers are a much better idea. You can wash them (don’t use fabric conditioner, as this will reduce absorbency) and they will last for years with careful use. If you do use ones made from recycled synthetics (like nylon, polyester or recycled plastic bottles), launder with a microfiber catch bag, to stop microplastics escaping the machine, and going in to the sea. They obviously also work out cheaper, long term. Also see the best zero waste food wraps and silicone food covers.
