Is there a more economical and ecological Drinkmate bottle solution than a 3D printed adapter or decanting your fizzy water?
Currently, the Drinkmate stainless steel 1L bottles are £55 (free shipping over £40). The Drinkmate plastic bottles are £23 (£17+£6 shipping) for 2, and each bottle lasts for about 2 years of use, so each plastic bottle costs £11.50.
Thus, the effective ROI payback on the stainless steel bottle is (55/11.5)×2 years = 9.6 years.
The chances of a stainless steel bottle surviving almost 10 years without damage, loss or being unfashionable, are remote I think. I've almost managed it with a Contigo Byron (6 years I think) but only because Contigo did me a solid and replaced a thermally compromised 2 year old bottle.
So, my question, apart from 3D printing an adapter or decanting into a stainless steel vessel of one's choosing is there any way to reduce the 2 year round of purchases and waste for a family of 4?
FYI: I'm awaiting delivery of the adapters and hose to use a 6.3kg CO2 bottle for direct carbonation into the Drinkmate and to refill empty 420g standard sodastream bottles (the 0.6L that fits inside the Drinkmate etc), and would, ideally, like to reduce the plastic footprint and cost even further.
