All our recycling goes in the one bin & it's sorted automatically by a combination of scanners.
I had a longish chat this morning, with one of our local authority recycling officers, about plastic recycling & the coding system.
It's the first time in my life I've heard a woman get excited when I mentioned Polyethylene Terephthalate so goodness knows what she'd have been like if I'd progressed our conversation to High-Density Polyethylene.
