Quite a lot of glass, for one thing.

A former colleague told me of an interesting experience he'd had in a
former life (job) getting rid of a decommissioned mainframe. He had all
sorts of quotes from people wanting to charge him for disposing of the
kit, and a local scrap dealer offering to /pay/ him for it. It turned
out that mainframes of that age had enough gold in their contacts for
it to be worth recovering it (by dissolving it in cyanide, I gather --
don't stand downwind!). The cabinets would have been good for scrap
metal, the rest was probably landfill.

Cheers,
 Daniel.

the Zilog Development system has over $320 of gold in it.

What?? Tell me more, I've not found it.

Surely they do get recycled somehow or is it landfill? The tube has all
sorts of toxic nasties in it.

Domestic CRTs get put in wheelie bin and go to landfill.

Same as all those ECO friendly bulbs that contain mercury.

That's just ignorant fools doing it wrong. Big surprise.

Our wheelie bins have stickers on with a whole bunch of "Don't put
these things in here - put them in the recycle bin or take them down
your local recycler".

OK a few do get taken to the tip. CRTs/electronics go in a container.
They have a sealed "coffin" with a tube sized airlock for tubes. The
last time I took some they seemed quite surprised, I think most people
just break them to fit the wheelie bin. I'm about to see they how get
on with 3 ECO bulbs. I've got 2 5ft tubes, a car battery, 10L engine
oil, 3 oil filters, 2 14" CRTs, 1L brake fluid to go too, bet I have
to sign for every item in triplicate due to toxic nature of them.

Our local tip has a half-container that's always fairly full of TVs
and monitors, a half-container that's always fairly full of random
electronics (mostly PCs and stereos), and a sort of enclosed skip
affair for fluoro lamp tubes large and small. Plus a lovely greasy
used engine oil thing.

It doesn't have anywhere specific for oil filters or brake fluid, as
far as I know, but I've never had to recycle those.

Ours too, except it's a "recycling centre", not a tip.

At our local tip, they simply take the CRT, sit it on a table, a guy
smashes it with a big hammer enough to get to the yoke and get it off,
this then goes into a barrel with all the others, presumably to
recover the copper. The rest just gets pushed over the edge into the
tip face with all the other useless household waste already in there.

IF there is a power/VGA cord that gets chopped and thrown in another
barrel (for copper again?)

Any TV's (or other such gear) that still work and look saleable, are
sent to the "recycling shop" at the tip where people can buy them for
very little money. If not sold they presumably go to the guy with the
hammer to be smashed for the yoke.

You must live near me. I have yet to see anyone care about anything
other than the yoke on a CRT based display and a hammer is indeed the
tool of choice. However, judging from the replies thus far, it seems
we are the exception rather than the rule.

Our local dump is quite relaxed about accepting poisons ... I think
they'd rather people handed them in for safe disposal than tipping them
down the drain.

I acquired (most of) half a litre of something called "Hobby Black"
(used by model railway enthusiasts to blacken over-shiny metallic
parts) among the effects of my late father (no, it's not what killed
him) -- this stuff seems to consist mainly of selenium dioxide in
methanol, and I really /wouldn't/ like to ingest any AT ALL -- and the
folk at the dump took it off to their toxic waste store with nary a
murmur.

Cheers,
Daniel.

I bet they don't even discharge the HV from the tube. One day it will
bite them. Not a little nip like the lighting that caps have in them
but a full on bolt from the blue. Even TV/CRT caps can kill but most
do live to tell the tale, very few can tell about the HV.

Or nip the end off the tube to allow air in at a controlled rate. OK
breaking the electron gun end is moderately safe until they hit the
one that implodes.

There was no attempt to discharge the EHT that I saw. The only
"protection" the guy had that I can remember was leather gloves that
covered arms and wrists.
I can't remember if he had safety goggles or not, but I would presume
that he would have to have if working breaking glass.

There's quite a collection of videos there now.

I heard of a couple of old Pegson rammers for sale and was going to
buy them, one for a friend so we could have races. Unbelievably they
went for over Ł150 each, non-working (though only needed their
magnetos rewinding), too rich for me. Wish I'd bought a few when they
were Ł30 - Ł50, it's amazing what's a good investment nowadays

Our tip has a friendly and very helpful guy who decides where the
different stuffs you brought need to go. Some of them he resells from
his Portakabin.

How do they work? On at least one of the videos I can see what looks

looked as if he was (unsuccessfully) trying to start his by bouncing it
up and down. Is the piston connected directly to the business end
instead of having a crankshaft?

Yes - it's basically a 2-stroke engine with no crank.

Yes - it's basically a 2-stroke engine with no crank.

Although I did find a manufacturer's website which had 4-stroke
versions, which must be a real engineer's headache in comparison (like a
Prius' Atkinson engine).

There's some history and some cutaway drawings here

http://www.google.co.uk/#hl=en&safe=off&q=the+history+of+warsop&meta=cr%3DcountryUK|countryGB&aq=f&aqi=&aql=&oq=the+history+of+warsop&gs_rfai=&fp=af53484c05009a1c

third item, a pdf

I think the people who write about four stroke ones are confused, they
were replaced long ago by compactors which use a small 2-stroke or
4-stroke engine to generate the bouncing via springs and reduction
gearing. More usable but less entertaining - and don't jump high
enough to crush stuff

It's essentially a stationary engine that moves, much like the old
tractors like Field Marshalls - they had a single cylinder 4.5 litre 2
stroke diesel engine, the rammers are petrol. The switch on the handle
fires a magneto for the spark. The bouncing (or with Johnsons pulling
a separate lever, or with Pegsons pushing the handle up and down)
clears any buildup of smoke and pulls through more petrol/air mix from
the carb.

I'm surprised Fred Dibnah (May He Rest In Peace) never had one.

About 20 years ago, the landlord in my office building was running an
office cleaning company[1] with a paper shredder sideline.  The paper
shredder was about the size of a large dumpster.  Every day, a pickup
truck load of paper would arrive and get fed to the hungry monster,
producing mountains of confetti and dust.  Dust and debris would also
fall from the ceiling as my office shook and rattled from the
vibrations.  This went on for about 6 months until someone
accidentally fed it the hand truck used to load the paper.  I would
normally expect the shredder to just stop or to disassemble itself,
but that's not what happened.  The interlocking teeth froze, the
overload switch failed, which caused the huge motor to rip away from
its mountings, smash through the side of the shredder, smash through a
decorative wood wall, and bounce off the landlords wife's car.  That
was followed by a dumpster full of paper confetti initially all over
the parking lot,

can't believe the overload protection failed, that is a ridiculous

That wasn't quite my reaction. I arrived near the end of the cleanup
exercise. I wished I had thought of taking photos as I had my camera
available. However, I was immediately volunteered to help with the
cleanup, which went well into the evening and continued the next day.

It probably wasn't all that spectacular, except maybe when it went
through the wooden wall. I only saw the damage. The launching of the
contents was the interesting part. The place directly above the hole
where the motor made its exit was the bin where the shredded paper was
unloaded. It popped open, dumping the entire contents all over the
parking lot. The wind did the rest.

There wasn't much damage to the car. It sorta bounced with a small
ding. Most of the energy had been dissipated by the side of the
shredder and the wooden wall.

We're both assuming that it had overload protection. My guess is
there wasn't any. The shredder looked like a home made contraption
that had never seen a safety inspection.
