That works in some parts of the world but I still don't believe the total environmental cost is as easy to calculate even in your scenario. The total cradle-to-grave environmental cost of a product has many variables and its not always as clear. Those variables can also have different weightings depending on the user (maybe microplastics is a greater concern that total environmental cost). In the past, even when accounting for recycling of the glass, plastic bottles for example had a lower environmental impact that glass. edit: And I enjoy using glass myself, especially for items I am storing longer term but I also try to think about the total environmental cost of the item. I know in the US people often do things that feel good, like buying reusable shopping bags instead of plastic bags given my the store. The problem is the number of times that reusable bags needs to be used to be better for the environment is often many more times than they often get used.
