Why is glass recycling bad for the environment?
Additionally glass is harmless in the environment, and it's not something we can ever run out of.
So why do it?
Additionally, if you actually do want to recycle things, glass shards contaminate everything, making it much more difficult and expensive (i.e. consumes more resources) to do it.
Making new glass can be an issue, as it typically uses sand, which is not very renewable and sand mining in many countries causes massive issues with flooding, droughts, sinking, black markets, even sand mafia!
No we should not landfill everything after a single use, or we will soon run out of reasonably accessible raw materials in suitable forms.
And no, we will never run out of it - the planet is made of it.
