Why Thermos Flasks and other glass vacuum flasks are not Zero Waste!

I’m publishing this post as a warning to all that purchasing a Thermos brand or other brand flask, with a glass vacuum liner is just about the WORST choice you can make when trying to live a Zero Waste lifestyle. They are promoted as an alternative to buying drinks out and will potentially save you money.

I grew up with my parents taking them everywhere – in fact they still do! It always used to be the case that you could buy a new glass liner, if yours ever broke. I chose a glass lined one because they are known to keep drinks hotter for much, much longer than metal walled flasks and I thought I would be able to replace the parts as needed. But be warned- not any more! You have to buy a whole new flask – you cannot buy a replacement branded or otherwise, not anywhere! This means your entire plastic flask has to go in the bin. Let me tell you that I am completely horrified at this state of affairs. I hope that Thermos gets bombarded with complaints which forces them to bring back the replacement parts.

I wonder just how many perfectly good flask shells are sitting in the bin, for want of a glass liner. Honestly, the thought makes me feel slightly sick!

I’d love to hear if anyone knows of a truly Zero Waste flask – one that you only have to buy once!
