問題詳情：
All animals produce waste. We call it “waste,” but we all know it can be very useful. In some parts of the world, animal waste, or poop, is collected, dried, and burned for cooking and heating. 36
The Chengdu Giant Panda Breeding Center has an unusual way of using animal “waste.” The center’s 40 pandas produce about two tons of poop a day. This material is being turned into a new product called Panda Poop Paper. 37 After all, paper is made from plant fiber, which cannot be digested and simply goes through the body as waste.
Since pandas eat nothing but bamboo, their “waste” is perfect paper material. 38
Their stomachs haven’t fully developed for their vegetarian diet, so their bodies make use of just 20% of what they eat. The other 80% comes out as poop: very high in fiber and perfect for paper.
Once the poop is collected, it is cleaned with chemicals, crushed(碾碎), and put into frames(框架)to dry. 39 Because of its good quality as well as the worldwide popularity of the panda, gift products made from the paper sell well.
40 They got the idea from the elephant dung(大象糞) paper made at Elephant Conservation Center in Chiang Mai, Thailand. And Creative Paper Wales in the U.K. sell paper gifts made from sheep waste.
