"Old" news, but still really cool!
A teenager from South Africa won the 2016 Google science fair by developing a biodegradable SAP in her home kitchen using orange peels, avocado skins and lemon juice. The only other things used were time, sunshine, and electricity (for her stove).
Sure hope this pans out, for South Africa AND the world. Put me on the list to buy some, but for now, I think I will try and make my own. I certainly produce lots of citrus peels (not all orange, so I will be curious to see if I get similar results with a mix of lemon, lime and orange) and avocado skins. My worms can't eat either one, so "wahoo!"
This girl has a great sense of humor, also. Check out the required "health and safety" portion of her entry.
I wonder how her current experiments are going...
