A Kickstarter project to make #sustainable straws from plant stems. Awesome! Check it out. I did back a similar one a few years ago, and did receive them, which was great, but sadly there have been no updates since then so I assume the business didn't take off.
Whilst the actual answer is that most of the time straws are unnecessary for drinking, at least this is a great solution - grow, cut, and then clean (i presume!), instead of creating something that isn't straw-like - paper, plastic, pasta, glass, metal etc. and then turning it into a tube. #sustainability #renewable
