Re: When I was a kid
Ah, those reverse vending machines. The big issue with them is that in order to work effectively, the deposit needs to be on pretty much every container type. This is the case in Denmark. It also needs some solid rules requiring all machines to accept all the container types. Again this is the case in Denmark.
However I live in the Netherlands, and much like Germany, the charge exists on 1.5+ liter plastic bottles and glass beer bottles. But each store gets to set it's own policies on the machines, so a number of supermarkets (Aldi, Lidl, Plus) will charge you the 25c/10c per container when you buy it, but make it very difficult to get the money back. You can only return bottles in a crate of 24, and no other option, and you cannot return bottles from other stores.
The net result is that the supermarkets make more money, and somewhere between 25-40% don't actually get returned. The fees are also pretty high relative to the item cost, a crate of cheap beer about half the cost is deposit, cheap soft drink 30% is deposit. The cost of running the scheme is higher than subsidising plastic or glass recyclers but an order of magnitude.
It's the same way we don't sort metals in our standard household waste. It's cheaper to recover it later in the collection process, since you don't ever get it cleaned enough in the separated waste you've got to have a shredding and washing proicess anyway, so just do it all as one.
I live in poor neighborhood, with a fair few rag and bone types. They know how much they can get for a bit of sorted scrap, and they do in fact drive around yelling for it. I buy bits from them, since I'll pay scrap value +50%, and a repairable bit of scrap is worth 400-10000% more than it's scrap value. Mainly it's computers and bikes, but even something as basic as a desktop (3-5 euros scrap value) I can get 20 euros from if I spend 30 minutes stripping and testing it. If I'm lucky I get 80+, but it's a gamble on what's still working. Laptops are pretty much worthless unless you find someone who wants the parts (hinges mainly).
I'm even lazier with the bikes, I pay the scrappy a tenner, a mobile bike repair guy 20, and sell it for 50. Bish bash bosh. Or 20 for a decent bike that's been mangled, and the parts go for 50.
The main problem Joe Public has with trying to sell their scrap is that you will get ripped off at every possible point by the scrapyards. Since my local little guys are my neighbors, and goodwill is priceless, I have explained to them that selling motherboards with RAM and CPU on for 50c a kilo when you can get 2-8 a kilo for the boards, and 30-100 a kilo for the RAM and CPU is leaving money on the table.
It's a classic example that the free market works, and of the value of information. You don't even need that much bulk, 1kg of RAM or 10kg of high grade boards will get you sensible prices from a refiner, as compared to the 100kg+ you need to get half decent prices on alu etc.
In general all IT goods (even laptops) are at the high end of e-waste, and are almost always worth the time. It's the white goods that get iffy, strip the wiring and motors and they aren't worth the time. CRTs are bad for your health, and if you're doing them properly are loss making. Which is why they are most often stripped of their valuable bits and dumped.
