The Science of Composting

This book chapter begins with an overview of the chemical, physical, and

biological changes that occur during thermophilic composting, thereby

providing an example of how several sciences can be integrated in the

study of composting. The overview is followed by more detailed, separate

sections on compost chemistry, physics, and biology. Much of the information

in the chemistry and physics sections focuses on thermophilic

composting. The biology section includes a discussion of the microbes

that are present in all types of composting, and of the diversity of invertebrates

that live in outdoor and some worm composting systems.
