Coffee grounds can be an excellent addition to a compost pile. The grounds are relatively rich in nitrogen, providing bacteria the energy they need to turn organic matter into compost.
About 2 percent nitrogen by volume, used coffee grounds can be a safe substitute for nitrogen-rich manure in the compost pile, explained Cindy Wise, coordinator of the compost specialist program at the Lane County office of the Oregon State University Extension Service.
"A lot of people don't want to use manure because of concerns about pathogens," said Wise.
Contrary to popular belief, coffee grounds are not acidic. After brewing, the grounds are close to pH neutral, between 6.5 and 6.8. The acid in the beans is mostly water-soluble, so it leaches into the coffee we drink.
Since 2001, Wise has trained and coordinated OSU compost specialist volunteers. They have collected and composted nearly 200 tons of coffee grounds from 13 coffee shops and kiosks in Eugene, Springfield, Florence, Cottage Grove and Veneta. That's the equivalent of about 25 large dump trucks full of coffee grounds.
