Not with their end product - the powder itself is excellent. But every little packet is plastic, and doesn't have to be. The world has such a serious problem with plastics, and for a lot of products it's kind of necessary, but this is not one of them.
Restaurants have had the same size single serving packets for sugar, salt, and pepper for decades now and those are paper, which is much more environmentally friendly. It's even better for usability! With paper, I don't need to go find my scissors like I do for TWW's plastic packets.
I asked TWW if they would consider using paper instead, but got a generic reply that they'll bring it up, but evidently nothing has been done about this.
Is anyone else as disappointed as I am with their use of plastic packets? I care a lot about having clean water for my coffee, and I care just as much about not polluting the rest of the world because of it.
There's also the "pavlis" recipe, or simply the potassium bicarbonate mix:
Make a concentrate of 10 grams per 100 mL, then use 1ml of concentrate per 1 liter.
Be sure to keep the concentrate in the fridge to slow down the growth of any civilizations, though. A 100ml batch lasts me about 6 weeks at roughly 4 shots a day.
