Have a look at Terracycle Royal.
As mentioned above, I set up a collection point because there wasn't one locally for a type of waste I wanted to recycle.
I also take the plastic bags from dry cat food to our vets who have a Terracyle collection point for these (we have 4 of our own and foster too so get through a lot of catfood).
Admittedly I don't recycle the single serve pouches because life is too short to wash and dry them. I do try to used canned or tetrapack food, which can be rinsed and recycled much easier as our council collect those, but most of our own cats won't eat the food in cans
.
It's worth understanding the symbols on plastics and what your own council accept. As I said above, our council accept 1, 2, 4 and 5 type plastics.
This excludes the aforementioned cat food bags, and also overwraps from can multipacks - there is another symbol that indicates that the producer has paid a levy for using non recyclable material - this is what funds the likes of terracycle - it's a little swirl without a number.
Our council website is quite good in detailing how to recycle as much waste as possible. I do what I can and don't feel guilty about what is non recyclable because our council has a waste to energy incinerator, so it's not going to landfill anyway.
But I do have the odd 'what about' thought about the ethics of being involved in animal rescue with a no kill where possible policy, because we're facilitating the lives of animals that could be humanely PTS instead of going on to spend up to 20 years eating a lot of meat and producing a lot of waste.
DP needs quite a lot of medication, but I have discovered you can take old inhalers to some pharmacists for recycling, likewise blister packs of tablets.
Admittedly, to make this all worthwhile, you do need space to store things and be organised. We have a utility room and pantry where a lot of this stuff is stored, and I always have things like boxes of glass in my car, to be recycled next time I go out (our council doesn't collect glass from homes).
