A few years back we had a conversation about reusing glass bottles
Many years ago I met a guy who was involved in launching the Sunny Delight product for P&G (I think it was P&G). He said they looked into reusable glass bottles because one of their mandates was to reduce the energy footprint (we would now say carbon footprint).
The problem with reusable glass bottles was they used a lot more petroleum than plastic bottles made from petroleum! They were heavy to ship, so trucks used more fuel for a given amount of product. Then you had to collect them and ship them back to the bottling plant, which also took more fuel than an empty truck. Then they needed to be washed and sterilized, which also took a huge amount of energy.
So reusing glass solves the landfill problem, but it makes the carbon footprint worse. Obviously, that equation changes if you switch to electric trucks and washing machines fed with solar power. But in most places, we're many years from that.
And thus one of my mottos: For every solution, there's a problem.
The real answer is that people should drink more tap water and less stuff from bottles, plastic or otherwise. As ,uch as possible, people should use powders that you reconstitute at the point of use, whether for laundry soap or beer (just kidding! For every solution, there's a problem)
