In Sweden, "special rubbish trucks go around cities and pick up electronics and hazardous waste such as chemicals." (1). You can look up how that works exactly. It's Sweden's way to do the EU WEEE directive.

In Copenhagen (this probably varies across Denmark) I have a small electronics bin in the apartment building basement, with all the other bins. Officially, I think its to be used for anything that fits, with larger things taken somewhere else.

When I dispose of my desktop PC, I will take 5 minutes to unscrew the motherboard, drives, PSU etc and put them in the electronics bin. The case will go in the metal bin.

When I dispose of old elections at work, the whole lot goes in the large waste electronics container.

Those 486 towers with turbo buttons are going for >$500 these days. Seriously search ebay for a 486 and you'll see the crazy prices they are getting.

Metal recyclers are in every major and many minor cities. EBay also has a thriving gold recycling community. Search "Gold scrap"
