Recycling Inedible food waste
1.Used coffee grounds make excellent exfoliators?
This is real! UpCircle Beauty have so far turned over 100 tonnes of coffee grounds from London coffee shops into exfoliating cream. Other innovators are turning used coffee grounds into logs for fires, building materials and substrate for mushroom growth.
2. Rice straw, a waste product from the rice harvest, can be turned into reliable roofing material.
Correct! Rice straw is a by-product from the rice harvest and can be turned into a number of bio building materials. According to the FAO, roughly 800 to 1000 million tons per year of rice straw is produced, so it makes sense to put it to good use.
3.Leftover grain from the brewing industry is regularly dried and used to fill bean bags and cushions.
Fake! However, grain leftover from the brewing process is now being re-used in other ways, like as feed for cattle, or in baking. In both cases, the valuable nutrients still in the spent grain are made use of.
5.Cow’s ear hairs are used for the bristles of paint brushes.
It's real! Although there are synthetic brushes out there, many artists suggest you can’t beat a good Ox hair for watercolours. Squirrel, pony, goat, and pig hair are also all used and have qualities suited to different types of painting.
