How do you make paper? Take plant material, add water, pulverize it, add chemicals, and spread it out. That’s pretty much what an elephant does. Elephants eat so much plant material that they defecate 12 times making a pile of 200 pounds of pooh. The elephant pooh makes great paper when processed. A manufacture in Sri Lanka takes the dried dung, boils it for a time in water to kill the bacteria, then adds scraps from recycled paper. Dyes and chemicals are added to change the color and consistency. Afterward, they make a slurry and pour it into paper screens. The resulting product is popular with tourists and as an international export.
