I don't understand why it's not easily recyclable anymore. Can you elaborate? I'm not arguing, I don't know anything about it really but caught that video above a few years ago and it seemed relatively straight forward.
Ran heavy equipment many moons ago. I have some experience with recycling.
It's not that it's not "Easily recyclable". It is. It's just that it's cost prohibitive.
99% of recycling in the West is done by private companies. Very few governments have their own actual facilities, staffed with government employees and machinery. So most material handling is contracted out to corporations that do. Think the big ones; Waste Management, BFI, Waste Connections, GFL, and a few others.
It's just that glass is worth essentially nothing.
In it's base form, glass is just sand. Breaking it down, gathering it, shipping it and then crafting it into a new product all costs money. And that cost is more than manufacturers and suppliers could pay to simply use new glass. So most recycling companies will just throw it in landfills.
Even so called "green" governments will admit they outsource most basic recycling to the private sector, who then still have to make a profit to survive. So they only recycle material that actually makes them money. Everything else gets thrown into the trash.
I could go on, but that's the jist of it.
