First there’s BIOTA, which claims to biodegrade within 80 days in compost. Biota is still a bottled water, in other words, it comes with water in it, but we also found one that is meant for refills…

Then there is the “Better Water Drinking Filter,” from Sunrise WD which looks like a regular water bottle, except it comes with a built in filter (reusable up to 90 times) and is also biodegradable in “80 days of compost.”
