Bagasse, the waste from sugar cane, was the second-most popular biopower feedstock through mid-year, according to Global Energy World, which tracks trends in the industry.

Close to 26 percent of biopower feedstock came from bagasse. Those results were driven by sugar cane’s status as a major crop in three of the world’s largest biopower markets: India, Brazil and China.

Wood waste was the most commonly used biopower feedstock, according to Global Energy World. Roughly 32 percent of biopower firms used wood waste as the primary feedstock in their operations.

Municipal solid waste, also widely available, was the third most popular feedstock at 16.7 percent.
