Learn About Our Zoo Doo Program
Woodland Park Zoo's Zoo Doo is the most exotic compost available in the Pacific Northwest. Zoo Doo is a fully composted blend of select animal manures mixed with bedding materials such as straw and wood chips from around the grounds of the zoo. As a conservation organization, Woodland Park Zoo is committed to being a steward of the environment and turning animal waste into a valuable resource is just one example of our sustainability efforts.

Whose Poop?
All the herbivores (plant-eating animals) and many carnivores (meat-eating animals) are happy to doo their part. Rhinos, giraffe, gorillas, tigers, zebras, and many more provide plenty of material to work with! Woodland Park Zoo composts approximately 500 tons of this animal waste each year—saving around $125,000 per year in disposal costs.

Creating Compost at the Zoo
How It's Made
The process begins when fresh manure and bedding materials are collected from animal habitats. Next, the materials are taken to the Zoo Doo yard for composting. We use an Aerated Static Pile System to do the composting.

Composting at Home
Woodland Park Zoo is not the only place composting can be done, nor does it have to be done on such a large scale. You can create your own compost in your own backyard. It makes sense for the zoo, why not for you?
