Getting rid of an old computer isn’t as simple as tossing it in the trash. Computers contain metals, plastics, and glass that can be recycled, along with hazardous materials like lead and mercury that need careful handling. Whether you’re upgrading, decluttering your office, or clearing out a closet full of outdated electronics, here are the answers to the most common questions about responsible computer disposal.
Frequently Asked Questions
How do I dispose of an old computer responsibly?
You have three good options: recycle it, donate it, or sell it. Many recycling facilities, electronics retailers, and donation organizations accept old computers and handle them properly. The one thing you should always do first is wipe your personal data. A factory reset is the minimum, and data-wiping software like DBAN gives you extra security.
Can old computers be recycled?
Yes. Metals, plastics, and glass inside computers can all be extracted and reused. Recycling facilities dismantle the machine and separate the reusable materials. Many cities have e-waste recycling programs, and retailers like Best Buy and Staples have electronics recycling drop-off stations in most locations.
What should I do before getting rid of my old computer?
Four things, in this order:
- Back up your data to an external drive or cloud storage
- Wipe the hard drive using data-wiping software (DBAN or similar)
- Remove the hard drive physically if you want maximum security
- Check for attached accessories like USB drives, CDs, or memory cards
Where can I donate old computers?
Schools, charities, and nonprofits that refurbish computers are always looking for donations. Organizations like Goodwill, Salvation Army, and Computers with Causes accept working machines. Check that your computer is in working condition first — most organizations can’t use non-functional devices.
How do I safely wipe data from my old computer?
Use data-wiping software like DBAN or CCleaner to overwrite the drive securely. For extra protection, physically remove the hard drive and destroy it (a drill through the platters does the job). If you’re donating a working computer, a factory reset is the minimum step. Always double-check that no personal files remain.
Are there companies that pick up old computers?
Yes. Junk B Gone picks up old computers and electronics as part of our regular junk removal service in the Seattle area. We handle the hauling and make sure recyclable components are processed properly through our nonprofit Second Spark. Some local recycling centers also offer free or low-cost pickup for e-waste.
What parts of an old computer can be reused?
More than you’d think:
- Hard drives for additional storage (if they still work)
- RAM and GPUs if they’re compatible with newer systems
- Monitors, keyboards, and mice as spare accessories
- Power supplies and cables can be reused or donated to repair shops
Can I sell my old computer?
If it still works or has valuable components, absolutely. eBay, Craigslist, and Facebook Marketplace are the most common options. Apple, Dell, and Best Buy also have trade-in programs that give you store credit. Even non-working machines with decent GPUs or SSDs can fetch a fair price from buyers who want the parts.
What happens when old computers end up in a landfill?
Nothing good. Lead, mercury, and cadmium from computer components leach into soil and groundwater, causing long-term environmental damage. E-waste is one of the fastest-growing waste categories globally. Recycling or donating your old computer keeps these hazardous materials out of the ground and recovers valuable metals like copper and gold.
How do I find e-waste recycling near me?
Start with your city or county’s waste management website — most have information on e-waste drop-off locations and collection events. Websites like Earth911 have searchable directories by zip code. Best Buy and Staples accept electronics at most locations. In the Seattle area, King County’s e-waste program and local transfer stations accept computers for free.
