Recycling information in Mercer County: The Mercer County Improvement Authority has links to curbside recycling schedules and hazardous waste recycling, including electronics equipment. The next electronics recycling day is scheduled for Nov. 14, 2009 9AM-2PM. More info on that here, with a link to a PDF about the plan.
Don't forget about freecycling- the program of letting folks take your usable but unneeded items off your hands, while perusing the stuff of others. Mercer County Freecycle maintains a Yahoo group, where you can subscribe to their listserv and peruse their rules for use.
I've gotten a lot of serches about recycling lately. You ask, and here at CoNJL we eventually get around to attempting to deliver!
