Coffee grounds make good compost for some gourmet foods, Kansas State University researchers say.

Students and faculty took used grounds from a campus coffee shop and composted them into soil where they grow mushrooms at the K-State Student Farm, according to a prepared statement from the university.

Besides helping mushrooms flourish, they calculate they put 50 pounds a week or about 30 percent of the coffee shop’s total waste into useful compost instead of landfill material, the statement said.

The grounds seemed to serve as particularly good compost for oyster, shiitake and reishi, all gourmet mushrooms, the K-State statement said.
