I don't know what you mean by this.
If you bottle stuff into PET bottles (the usual stuff, being shredded after one use), then you have to buy one new PET bottle for each bottle you produce.
If you bottle stuff into reusable glass bottles (98+ % returned intact, cleaned and reused), then you mostly don't buy new bottles, just replacements for bottles falling out of the cycle (reuse limit reached, not returned, broken).
Why and by what mechanism would the price of a single new glass bottle account for the lifecycle of the bottle? It just doesn't make sense to me.
- RyEgswuCsn 5y agoI think what the parent comment meant was that for the environmental impact of producing and transporting a glass bottle (glassware are heavy), one can produce and transport many PET bottles. The ratio can be high enough to the point where producing a glass bottle is more environmental impactful if they are not reused enough.
