Rinsed and washed? pointless and a waste of both water, cleaning products, the energy used in the process of supplying, cleaning and treating the water, as well as any cleaning products you might use and for that matter the ATP used to power cellular respiration when you move your muscles to turn taps or scrub shit.
Two other reasons it is utterly pointless. Any glass or plastic isn't recycled in the state it is in when you toss it into the recycling bin, as proof of that pudding, they would stipulate no broken glass or damaged bottles. It all has to be melted down. And for paper it would have to be bleached, and sent all the way back through the pulp states, including treatment with oxidizing agents.
Think a bit of burnt-on baked beans and tomato sauce is capable of surviving the temperatures required to melt steel? how about molten glass and beer stains, bits of coagulated milk protein?
Don't waste your (or his, rather) time, there just is not the least point in cleaning them. They do it. And so I've heard, quite a bit ends up in chinese landfill sites. Thats nice of them, no?
Giving a shit is good, Do give a shit, hell give two. Just don't fill a bathtub with faeces and snorkle in it singing ave fuckin' maria.
