After I bought my new computer, I still had my old computer parts to dispose of. I didn't want to drop my only computer parts in landfill, since they are hazardous waste, so I needed to find a hazardous waste site for them.
I looked online for sites which accept electronic waste, but the Los Angeles city-run sites only were open Saturday or Saturday and Sunday--not very convenient. I read on Green LA Green, an excellent environmental blog for Los Angeles, that Amoeba record store accepts in Hollywood accepts e-waste, but on a visit their "Big Green Box" was really a very small green box only accepting batteries and cell phones; I did give them my batteries and portable phone. The sales clerk suggested I take any working parts to Goodwill on Vine Street just south of Fountain, which I did. I had two speakers which worked, so I dropped them off at Goodwill.
Still I had to find a hazardous waste-home for my huge old computer monitor and the CPU unit. On Worldchanging Los Angeles, I read about California Recycles, a store which accepts computers and then recycles them. They recycle CRT monitors, TV sets, cell phones & accessories, stereo equipment, DVD & VCR players, computers & accessories, scanners & fax machines, batteries of cell phones and laptop batteries. They say on their website that they want to make electronic waste recycling easy and convenient.
Better yet, they are in West Los Angeles near where I work and also are open Monday-Friday 8:30-5. So I drove there, and gave them my old computer and CPU unit.
The man working there even helped carry my computer monitor into the store as it was too heavy for me. I asked him, "Why do you do with the old computers and monitors." He said some they dismantle and sell the parts while others they fix and resell. They also gave me a certificate that they would erase the hard disc.
