If you haven’t used if for 12 months, and it doesn’t hold any specific sentimental value, get rid of it … in an eco-friendly way, of course. Try eBay or donating the unwanted items to charity. However, don’t inundate charities with junk. Responsible recycling is an option for many items. For e-waste, I recommend e-cycle recovery. They will charge you to dump your e-waste but they will dispose of it in the most environmentally responsible manner, and ensure that heavy metals and other contaminants that are embedded in circuit boards, hard drives and CRT TVs are properly handled. Do the right thing: declutter your space, but do it responsibly.
