couple of questions about recycling E waste proccess??

ok ladies and gents
Im thinking about setting up a business recycling ewaste, computers, TVs etc.
before you go and say its not worth it, i understand where your coming from but every small operation ive seen looks for one thing (normally gold)

anyway im looking for a faster way to actually pull the PCB apart, so i can get at the gold pins mostly. I was thinking something like a BBQ, with a fume cabinet on top, at a low controlled heat to melt the solder (that can then be recycled) thoughts?

secondly im looking for a place i can recycle capacitors, i know there are none in Australia but if i remove them, vacuum seal them, box them and then send them to america for being recycled (i dont mean to send our waste to other places but i really don't want to go and dump them here)

lastly the copper tracking on the board is there a way to get this off? i know they are made with chemicals but is it possible to get them off and recover it??

some further information, this is not my first foray into business, i am not looking to get rich quick, my planned production place is a business where we fix electronics (battery chargers, golf carts, forklifts etc) my main aim is to help the community, maybe make a dollar or too and basically clean up.

thanks guys

It's not cost-effective. Too much dismantling.

thats why im looking at how to dismantle them faster, taking the screws out of a computer isnt hard (with an electric or air screwdriver)

also people who take things for free wont work out, once a year we have a free E waste drop off the rest of the time it costs upto 5 dollars a kilo to dump it and who knows where it goes then. Government laws only apply to the country (makes sense) a large amount of stuff goes out of the country to be broken down.

also theres the fact that people are forced to pay for the removal, and government incentives
Be a recycler of e-waste there will be many government and international guidelines you will have to follow in haw you handle the materials. Simply placing a PCB into an oven to melt the solder away isn't so simple. There will be all sorts of regulations about how its done and how any fumes are handled. To really get at any gold or copper on the boards you'll have to use caustic chemicals and solvents to separate the metals from the boards, clear away any PCB masking and remove the solder. Capacitors aren't the only chemical hazards. Many board use Lead in there solder and some components have Lead in them as well. No to mention you could run across items with some Mercury in them.

Before you move on check what laws govern this sort of business before you jump into it.

BTW the real profit in e-waste isn't gold but copper. There is so little gold in there you spend more time and money trying to get it out then what it's worth. Usually only connector pads are gold. The traces leading up to the pads are all copper. So the real money is in recycling the copper.

Most businesses like this i've seen only break down the electronics and sort it out. Then don't try to reclaim any materials like the gold or copper. For example they will take an old CRT TV, crack it open and sort it into piles. The Tube goes in one pile, the circuit boards into another, any metal plates or screws go into a metal bin and the plastic casing goes into it's own bin. Then they ship those bins off to locations where they have the facilities and certifications to handle the actual recycling. If you looking to create a facility like that then find one and visit it.

While there are a number of government laws and some international laws not all countries subscribe to them. A large quantity of boards are sent to 3rd world countries where they are broken down further, such as using an open air wok to melt the solder and salvage it (hence why im trying to set this up)

we already have a large number of processes involved but yes your right.

Thats what ive noticed but many few of the smaller companies cut it and discard t fairly quickly, yes i pulled a few computers apart to strip completely and sort (copper wires, gold, copper clad boards etc) my aim isnt looking for the gold but basically to clean up.

i wont be dealing with every material down to sale level mostly metals. But the rest will be sent out rather than stored.
One problem ive seen in Australia is the number of 'cowboys' collecting things they know have value in them taking it apart and dumping the rest on the side of the road. I spent some time cleaning a large amount of this up, including the plastics, glass even a full mouse that had the cable cut off and dumped hence my wanting to clean up.
