Since I'm still getting to know the world of sustainable living, recycling, scrapping, and everything related to that - I would be very grateful if someone gave me a few pieces of advice.
I would like to know what is the most valuable thing I should look for when scrapping electronics. I do understand that various materials can be found in different objects, but it's still unclear to me what objects can yield as great results as to be considered "Holy Grails" of e-scrapping - are those TVs, computers, cell phones, chargers, or what...
Also, I have a question regarding scrapping cell phone chargers & headsets. Recently I have come across a bag containing a bunch of cell phone chargers, headsets, a variety of cables, etc. My first thought had been to cut the cables in order to look for copper only, and there I was - stripping cables for copper, when a thought popped up in my mind - should I somehow separate copper I stumble upon (for instance - low grade, high grade)?
Nevertheless, when I stripped one particular cell phone charger (cable of the charger) - wires inside were "silverish", if you know what I mean. Is that aluminum, or what? I am also wondering what should I do with the "insulation" (looks like rubber to me, but I suppose it's some kind of plastic material - anyway "the tube" where the copper wires are located)?
I also realised that there are also other materials to look for, besides copper - probably aluminum, but maybe even silver or gold? And where are those located?
