【 摘 要 】

Biochar is a charcoal produced under high temperatures using crop residues, animal manure, or any type of organic waste material. Depending on the feedstock, biochar may look similar to potting soil or to a charred substance. The combined production and use of biochar is considered a carbon-negative process, meaning that it removes carbon from the atmosphere. This report briefly describes biochar, its potential advantages and disadvantages, legislative support, and research and development activities underway in the United States.
