Compost your leaves. This fall, the City of Chicago is offering discounted compost bins for $30 at two locations. On October 13th and 14th, you can buy them at North Park Nature Center's Harvest Fest (5801 N. Pulaski Rd). If you can't make it to the Harvest Fest, you can pick one up at the Center for Green Technology (445 N. Sacramento Blvd) on Wednesdays from 10am - 4pm or Saturdays from 9am - 12pm through November 10th. posted originally from: AT:Chicago For those who live in yardless buildings, you can try a compost tumbler on your porch, or (if you're willing) a worm bin in your kitchen.
