In my local council (I live in the UK), one category of confirmed recyclables is "plastic bottles, pots, tubs & trays". But surely not all plastic tubs can be recycled? Some of the plastic tubs I end up after using a food product may have a Resin Identification Code (RIC), but others aren't. Mushroom and meat tubs tend to feel different to normal PP (RIC: 05) plastic tubs, and generally don't seem to have RICs. I know that RICs aren't actually a guarantee of recyclability (e.g. in my council HDPE or any kind of bottle lids are not recyclable (too small)).
So, can all of the day-to-day plastic food tubs be thrown for recycling, even if they don't have RICs? I suppose it depends on the sorting facilities for each council, so if they can't sort bottle tops, should I avoid throwing sans-RIC tubs for recycling on the grounds they can't be sorted either?
