Not sure we understand your comment completely... Paper straws are made of a renewable resource so what you chose to call "waste" is actually something that can be used as a fertilizer or just being burnt for a quick-release of energy! Look to Scandinavia for best practice! The present paper straws are, as mentioned in the text, not a very efficient straw. A better paper straw is, as mentioned, more expensive so you need to add value to the product to get (or at least have a chance of getting) some market penetration/traction.
Hi Scott, thanks for your comments! Well, an obvious approach would be just to ask people if they would like a straw or not. This has worked well with glass straws in restaurants (they are a pain to clean afterwards) on Bali... Our assumption is that it is very difficult to get people not to use (and ask for) straws, in particular in the US.
Well, USA is not really in the forefront of sustainable foresting so probably it's not fair to use a non-participant in the Paris climate agreement as an example of anything ecological... Look instead to Scandinavia (e.g. Sweden, Finland) and you will see that all paper mills do clean their water very well. Paper can be reused 5-6 times and then deliver value (energy) by being burned! Paper is by far the second best choice for straws! The best choice is not to use straws but the "American Infantilism" has made the use of straws a must - even for adults! (PS: Dont' get us wrong, we love the USA).
