It's literally the law in the UK that such goods have a method of being 'taken back' so they don't end up in landfill.
I can't actually put any such goods in landfill if I tried, save for fly tipping. Even then the item would end up through the recycling chain.
I should add that getting rid of big items can be especially difficult, but most appliance delivery includes taking away the old one to .. wherever they go.
And because recycling it is one of the most pointless things you can do. It's sand, we have unlimited quantities of it, the planet is made of it.
I thought the glass process was basically melting sand and adding some trace additives, rather than forcing any chemical reactions uphill. Recycled glass also needs melted (if it doesn't, that's called a reusable bottle, not recycling).
