As of Jan 1, 2011 it is no longer legal in Indiana to dispose of computers in the trash.
As stated mid page here: Recycle Indiana: Indiana Regulations Affecting Electronic Waste (e-Waste) Unless I misunderstand the regulation.....
Or take it to the office and toss it in the dumpster. There is a small output exemption for businesses that need to dispose of a few computers, cell phones, etc. in the course of normal business.
"Conditionally Exempt Small Quantity Generators (for businesses that generate no more than 220 lbs of hazardous waste per month)"
Not saying destroy the earth, Just dont sweat throwing away an odd e-waste item in the landfill here and there.
But if you can find an e-waste recycler, please use them.
