Back in the '80s, my uncle and his family lived in Germany for about 5 years. Once a month, everyone put out their old bikes, washing machines, cookers, furniture, etc. and people could take anything that they wanted. Afterwards, the council would collect whatever was next for recycling/disposal.
Last time I weighed some metal in, they did insist payment had to be a tranfer into a bank account, but they didn't insist on seeing photo ID which I think they should have?
I've been wondering the same thing myself, having accrued a sizeable collection of old car and motorcycle batteries, not to mention a fair amount of old lead piping and electrical wiring... however - I also wondered if it worthwhile/cost-effective first attacking the batteries with drill/hosepipe/hacksaw/anglegrinder etc in order to (safely) extract the lead, so as to present that to the scrappy rather than the batteries?
More trouble than it is worth IMHO. I also (slightly) rob myself by draining the acid and rinsing out the cells with water, and emptying them. Remember that your strategy will also lose the sludge at the bottom of the cells and maybe from the plates themselves, which will contain a certain amount of lead as sulphate and oxides.

<snip>I think that's where you can get an issue ... and doing it seems more prevalent in people from different cultures.
They put something out they have finished with but is still useable (let's say a baby buggy) because where they (originally) came from, that's what everone did and it would always get taken by someone in need (to use or clean-up and sell etc).
The number of times I've seen what look like perfectly good / clean fabric sofas or wooden bedside cabinets left outside peoples houses and then it rains on them for several days ... ;-(
Someone does similar on an estate here where they will put out a pile of bones (for dogs or foxes presumably) and I've even seen a large whole fish!
The other things is fridges / freezers that I don't believe the scrap places will take (without being degassed?) so they just take the compressors out (I saw one whilst walking the dog late one night just collect the compressor that looked to have been previously disconnect but left in place).

Even on the moon too.
Being pedantic the mass will be the same but the weight, which should be measured as a force in units such as Newtons, would be somewhat less.
Being even more pedantic, Bill said ?fair load?, not weight. To me ?load? encompasses volume and weight, not weight alone.
Tim
yes, W = mg or more scientifically F = ma
SH
Being less pedantic and more accurate, *I* said you need 'a fair load', not Bill.
Bill was the one trying to be clever. ;-)
Eg, one carrier bag of brass might get you a fiver whereas 4 full rubbish sacks of crushed ally cans might get you £2.50 (and why we stopped crushing and collecting them).
You need a 'whole load more' to get anywhere with ally (obviously a right brainers term) and so better for the Council to collect and recycle them because they *can* get a whole load more from everone in the borough. ;-)

I was under the impression that a kilo of aluminium will be the same weight as a kilo of copper or brass _anywhere_.
It's just on the moon they'll both weigh about a sixth of what they do here.
Andy
With respect you've missed the difference between mass and weight.
Mass is independent of gravity and measured in kg. Weight is wholly dependent on gravity and measured in Newtons. Weight has never been formally measured in kg and it is confusing to mix weight and mass. In my o-level physics days weight was sometime given the units kgf (kg force). But it's not an SI unit.
There is a fly in the ointment. While mass is mass, weight depends on another factor, the medium it displaces. 1 kg of helium in a big balloon won't have a weight of 9.81N at sea level. Water when measured by weight will be 0.1% in error when compared to 1kg lead weight.
I think the point being made is that *in the same conditions* 1 kg of anything, no matter how dense or "un-dense" (what *is* the opposite of dense?), will weigh the same. 1 kg of feathers or of lead will weigh the same as each other on earth. They will still weigh the same as each other (but not the same as on earth) on the moon or a long way from any planet/moon.
At least SI has totally different unit names for mass and weight (or other force). So often US scientific or engineering texts will refer to "a thrust of 30,000 pounds". Wrong! A pound, like a kg, is a unit of mass. A newton (and whatever the imperial equivalent is) is a unit of force, whether gravitational weight or thrust from a jet engine. Or am I being too picky there? "A pound of force" is lazy shorthand for "a force equal to the weight of 1 pound (at the earth's surface)". And that "pound of force" needs a name other than "pound".
Yes, if you want to be really accurate, you need to take into account buoyancy in the atmosphere, so a large object of unit mass will weigh fractionally less than a small, dense object of unit mass because the former displaces a greater volume/mass/weight of air.
And don't get me started about a pound of gold weighing differently to a pound of flour because of the different definitions of troy and avoirdupois pound - it's little things like that which demonstrate that the imperial system was made up as they went along.
There is a unit called a poundal
No worries, I'll stick to SI units.
I wouldn't attempt to clean aluminium in the washing machine.
Bill
That depends.
Bill
I f****ng was not because I know it's hopeless.
Bill
My greengrocer is quite formal and he weights things in kilograms.
Bill
Yet many people do of course.
