All animals produce waste. We call it “waste”, but we all know it can be very useful. Farmers have long used animal and human waste as a fertilizer (肥料). In some parts of the world, animal waste or poop, is collected, dried and burned for cooking and heating. 1.

The Chengdu Research Base of Giant Panda Breeding has an unusual way of using animal waste. The pandas in it produce a lot of poop a day. 2. It’s not strange. After all, paper is made from plant fiber (植物纤维), which cannot be digested (消化) and simply goes through the body as waste.

Since pandas eat nothing but bamboo, their waste is perfect paper material. 3. 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.

After the poop is collected, it is cleaned, crushed and poured into frames to dry.4. No one can guess where the paper comes from. And because of its good quality (质量) as well as the worldwide popularity of the panda, gift products made from the paper sell well.

5. They got the idea from the elephant dung paper (由大象粪便做的纸) made at the Elephant Conservation Center in Chiang Mai, Thailand. And Creative Paper Wales in the UK sells paper gifts made from sheep waste.
