Basically an automated chop shop/junk yard. A factory with machines to handle every part of removing parts from a car. It would remove all paint, oil, grease, battery fluid, elephant semen, and so forth, grind down or weld up the parts that deviate from specs, trash the parts that are unrecoverable,
and output all possible parts sealed and ready for resale. One factory per brand of car.

This already happens, Just without the cleaning and bagging. |

This already happens - there was a fascinating piece on it on "How do they do it?" (UK television programme - Channel 5, Monday night - required viewing for Halfbakers). All fluids are drained or siphoned from the car (e.g. the sump was drained by drilling a big hole in it) and collected for recycling. The car was then put in something like a massive paper shredder and then the small chunks of car sorted first by magnets and then by people picking out different things as the chunks of car went by on a conveyer belt. |

[hippo], I worked at one of those facilities for a short time. Imagine something that is 40t & rotating at 600rpm, with 40-odd 200kg hammers free to rotate on 4 equally spaced shafts. Insert one car and a few seconds later a pile of shrapnel appears underneath. I always thought it was a good way to get rid of car bodies, and any other type of bodies that happened to be lurking in the boot.
Occasionally there was a petrol explosion. I remember a 4t roof, which was bolted every 300mm with bolts as big as your arm, being blown completely off. Crankshafts used to come out in a series of blue balls at immense speed. A demolition ball put the machine out of action for a week: the rotor came to a halt in about a quarter of a turn. |

Non-ferrous metals used to be sorted out onto one line, and I set up the linear motor separators so that all the coins came out on one conveyor. As you now know, the only way to get the coins out from the back of your car seat is to send the car to a shredder. |

Automobile manufacturers are required by most countries to document the material content present in each nut, bolt, bearing, bushing, fender, and whatnot, right down to the coatings on them due to material regulations and restrictions. For instance, Europe is imposing a regulation on the amount of lead content in alloys, which has driven development costs upwards lately. Some components like bushings are getting a by for now as the removal of the lead is currently technically infeasible. |
|
| |
For the bits of electronic junk, lcd panels, and whatnot, I'm more fuzzy on what the rules are. |
|
| |
I believe it is actually cheaper to break up a car and then re manufacture the parts from raw material than to take it apart and recondition the parts. The Auto recycling industry is focused around the recycling of only the highest value parts(most often this is engines, Glass and body parts that are easily removed and normally only on the newest vehicles. |
|
| |
Yes that's usually the case. In many cases, reconditioning is impossible anyways. |
|
| |
[-]Most cars have over 1000 parts that range from something as large as the engine block to something as small as the little clip that connects the door handle to the latch. Used parts are more efficiently stored on the cars themselves allowing the customers to pick off what they need until it becomes an empty carcass. |
|
| |
It's a nice thought, but cars have parts that turn into rust, tiny metal shavings, and bits of fiber that you can't do much with in terms of reconditioning. Wires burn out, fasteners rust, many parts are attach-once only, etc. |
|
| |
Forcing manufacturers to 'buy back' their cars is a proposal that is on the books somewhere and not a terrible idea, imho. |
|
| |
This idea is Excellent. And i'm Quite Convinced
that robots will make it possible (forget saving the
paint though). At present it is Too Expensive to do
this. 1) cars are not Made to be recycled. 2) it
would take a human Too Long 3) some materials
are not recyclable. |
|
| |
However, robots, can and will take things apart.
Products need to be designed with recycling in
mind (or be fined / taxed). |
|
| |
I love this idea. I'll do my bit to rid you of fish! |
|

manufacturers should pay for the disposal cost of the product. long lived items with a high value for recycling should be returned to their maker for disposal. Companies might get a lot smarter about re-use and reduced waste. the "used things are worn out and worthless" is a myth. Metals do fatigue and corrode, but most parts of a car do not fatigue or corrode and could be designed for refurbishment and re-use. |
|
| |
All of this is based on a very dubious and facile
assumption: namely that it is somehow "better" to
refurbish components than it is to recycle the raw
materials. |
|
| |
[Ian Tindale], [Voice], [nicholaswhitworth] and [WcW] are
all guilty of a very simplistic and potentially harmful way of
thinking. |
|
| |
Why, exactly, is it better to refurbish components than to
melt them down for raw materials? Does it save on
energy? Does it result in less pollution? Does it actually
benefit the environment? |
|
| |
Perhaps it does, but it is naively foolish to make such
assumptions. I actually suspect that it takes less energy
and causes less pollution to shred a car and turn the
recovered materials into new components than it would to
dismantle it, and then treat and test each of thousands of
individual components. |
|
| |
An awful lot of bollocks is talked by well-meaning people
who would like to save the planet. I may be completely
wrong in this case, but it's a question that ought to be
asked. |
|
| |
// well-meaning people who would like to save the plane // |
|
| |
Well, don't look at us. Bear in mind that (a) we are Evil Incarnate, and (b) while we want to save your planet, you have no idea of what we want to save it for (think strip mining, but on a somewhat bigger scale). |
|
| |
// I may be completely wrong // |
|
| |
// Perhaps it may become cool to boast about your new
thing that you've bought that is leading edge
technology, nice and spiffy, and of course contains the
expected and by now socially demanded smattering of
'vintage' parts with their refurbishment certification and
other systemic metadata. // |
|
| |
I will do my best to bring that about. I already have a
project starting (kinda like this idea, but not for cars,
and not specific to individual models) and some projects
in planning that will do a lot of that. I will add links
when they're online somewhere. |

Indeed, let's not assume component-level refurbishment
is better than material-level recycling, but let's also not
assume it's worse. Let's try both at a reasonably high
level of development and compare them. |
|
| |
What's needed is a really, really big mass spec. Car
in, isotopically pure elements out. |
|
| |
It's economic to shred car bodies if they're more than a few years old. Until then, there is a fair market for late model sheet metal body parts. |
|
| |
Typically engines and transmissions and differential gears are economic to rebuild. A rebuilt replacement engine is typically 1/2 to 2/3 the cost of a new crate engine. |
