The total amount of energy required to produce glass bottles of 500 ml is approximately 34 mega joules. It is slightly more than the production of polyethylene terephtalate plastic bottles of the same volume, which require 32 mega joules.
But, for the production of glass bottles, which are made of 50 percent of re-processed (recycled) glass, you need only 30 mega joules. Such bottles may still be recycled almost countless times.
With the plastic is slightly different.
Used plastic can be processed, but it is not used for food industry to avoid spoilage of nutrients and because even the smallest particles of polyvinyl chloride (PVC) may irreversibly damage a large amount of polyethylene terephtalate (PET).
Recycled plastic does not reduce the amount of new plastic bottles or the cost of their production.
We should not neglect the fact that, during the production of plastic bottles, into the atmosphere is released a hundred times more toxic gases than during the production glass.

Reusable water bottles have made it easy for us to stay hydrated throughout the day while cutting down on single-use plastic bottles. These bottles come in exciting shapes and eye-catching colors.
According to a 2019 market research report, the reusable water bottle industry was worth $239 million and is expected to reach $374 million within four years.
I personally prefer stainless-steel flask
, as Compared to all other bottles, stainless steel bottles keep their contents cold for longer.
