Why not mandate use of glass bottles with a deposit to avoid using so much plastic?
Thats exactly what I was thinking. Milk bottles were sanitized and refilled. Coke and other pop bottles had a nickel deposit. Many kids financed their comic book addiction by picking up bottles and returning them for the deposit. Paper bags were used for tons of things from lining shelves or bird cages to composting in the garden
I'd venture an educated guess that shipping in glass is cost prohibitive compared to plastic because of the weight difference between the two types of containers. Add the recycling costs of glass and the resources required (water, heat, etc..) and it's probably even more costly.
I think the article's conclusion is exactly right that we need to stop shipping plastic all over the place and simply incinerate it, reduce the bulk by 80% or more and make it more safe to dispose of vs. what's currently being done.
