Cashew-waste possible bio-degradable sunscreen in our future


http://www.wits.ac.za/news/latest-news/research-news/2019/2019-08/wits-green-chemists-find-a-way-to-turn-cashew-nut-shells-into-sunscreen.html

With current concerns over the use of fossil resourcesfor chemical synthesis of functional molecules and the effect ofcurrent UV absorbers in sunscreens have on the ecosystem, wedescribe a xylochemical synthesis of different classes of aro-matic UV absorbers utilizing cashew nut shell liquid as a non-edible bio-renewable carbon source. Hydroxybenzophenones,xanthones, triazines, and flavones were synthesized startingfrom cardanol or anacardic acid. Several compounds exhibitedfavorable UVA and UVB absorption characteristics.

Impact of food waste campaigns muted, but point toward right direction -- ScienceDaily


They did a study at two univerity dining halls.
Our local university in Germany was also for some meals a take as many as you want food, but to fight food waste they rely both on posters etc. about food waste and they provide portions/ready made plates. In practice this means there is someone behind the counter who puts the main dish on your plate. In addtion, you can get pre portioned bowls of various side dish.
Still there is some food waste, but I think it helped a lot to reduce it.
