I've been exploring the issue of Ocean Plastics, and students will be putting together some ideas for how to tackle this issue within the school.
While shopping recently, I came across this product, which is packaged in a different type of packaging to the usual PET bottle.
The lid, however, seems to be made of plastic?
The website provides further information on the packaging and the product.

AQUAPAX carton strength is from renewable FSC timber sources
By weight, AQUAPAX contains at least 62% plant-based material 


What other packaging options could there be for portable water?
