Here at the holiday house, the owner has all these recycling rules, and I'll be damned if I can follow them to the letter. Wash these, caps off, blue bin. Wash these other ones, replace the caps, also blue bin. Smash these other things...also blue bin. Glass in the red bin, but not glass with this marking on it, only that marking. Wash this, flatten that, sort those...I can't keep it straight.
It's likely not the owner with these rules - it's likely the recycling company (or the city, if they take care of the recycling) itself. I'm not that familiar with recycling in the UK, but recycling is generally dependent on the local infrastructure, and the local markets. Some places (like where I live) have the infrastructure necessary to separate out recycling, so it can all go in one bin. Other places don't have that, so they have to ask people to sort into different bins. Some places can accept black plastic, or Styrofoam, or plastic bags, or bottles with the caps on; some can't. This, of course, all leads to massive amounts of confusion among the general public about what can and cannot be recycled. Hell, even I don't know whether some items are recyclable, and I've been working in the environmental field for over 10 years!
This is one reason why the whole recycling issue drives me batty. I get so many people coming to me like, "[My institution] doesn't recycle enough! You should recycle more!" and after I've explained the whole thing to them, they end up just as frustrated as I am. Add into that the whole contamination issue (people throwing stuff in the wrong bin, items that are dirty/greasy getting put into recycling, clear bioplastics that look like regular plastic but are marketed as "compostable" but aren't really...) and I'm ready to throw my hands up in defeat.
Hence, trying to cut back on packaging in general. I'm far from perfect, but I buy most of my dry goods from Bulk Barn and just bring my own containers to fill.
BTW, only around 11% of plastics actually get recycled. Recycling is far from the panacea that a lot of people think it is.
