Surely there is a better e-waste disposal process for old computers than the dumpster, including the parts for recycling. I typically disassemble my oldies down to the potentially reusable salvage. The case metal can be recycled. The mobo with chips can be 'fed' into the e-waste recyclers that manage such parts in an EPA acceptable way. If the PS, hdd, optical, and floppy aren't usable somewhere/anywhere, they should probably go to the same epa responsible disposal as the mobo/chips. Around here there are a lot of rules for such e-waste disposal, whether one is residential or business. -- Mike Easter

never fear, "the dumpster" was metaphorical. rethink, reuse, recycle, etc. "Mike Easter" <MikeE(a)ster.invalid> wrote in message news:7p4er1Fr3oU1(a)mid.individual.net... > SteveH wrote: >>>>>> Al-hphdx wrote: > >>>>>>> The PC is in the dumpster so the pressure is off. > >> Well, you've done the right thing with it... > > Surely there is a better e-waste disposal process for old computers than > the dumpster, including the parts for recycling. > > I typically disassemble my oldies down to the potentially reusable > salvage.
