So, if I want to buy a bottle of water in this bold new future, it will have to be a glass bottle?

Or these companies will have to put R&D money into safe, single-use decompose-able plastic bottles. There will be a huge market incentive to do so.

The benefit being we don't end up with oceans and landfills filled with the bloody things.

Thankfully our public spaces are rapidly adopting water bottle refill stations.

Plastic is brilliant, but it's meant to last a long time. Dirt-cheap single-use water bottles was never the design. It's an abuse.

Or aluminium. The better choice is to carry a reusable bottle, but I do forget it from time to time.

That could be an option. A returnable one.
