Used electronic components, like circuit boards make up a large portion of precious metals recovered each year

Recycling one Circuit Board can make three?

One circuit board doesn't make that much of a difference, but when you think about it, with the advances in technology, the precious metals that can be recovered from a circuit board of just a few years of age can now be recycled to make two or three circuit boards.

Your computer is no longer supported

We are in an age where our computers are being made redundant.
We are being advised that the model or platform that the computer is based on is no longer being supported, it seems to be ok, but the browser won't update and it says it's incompatible with my banking app. 

A New One?  But, but..... this is perfectly good!

And we simply have to buy a new one that is compatible, albeit offering the additional cyber security, with programs that somehow are faster and more powerful, but are squeezed into much smaller computer devices.

You have a circuit board in your key fob.

Circuit boards exist in so many pieces of every day equipment, from the one in your car key for the central locking of your car, the washing machine programme selector, your fridge, freezer, TV,  your toaster, the air conditioning machine that sits in the office cupboard, that is too noisy when you do use it, so you don't use it.

Remember the password to your old PC?

Then there are your old computers, that you have been meaning to check and see what is on the hard drive and you may want to keep (if you could only remember the password) and the huge inkjet printer that you use once, and need to replenish the ink cartridge a fortnight later.

Black ink is on the list of the 10 Most Expensive Liquids (no surprise there then).

Inkjet printers work on the the razor-and-blades business model selling one item at a low price point but profiting off consumable supplies, which takes us to the circuit board in your electric razor, something not dissimilar in size to the 7 remote controls on the coffee table that also contain circuit boards and the slide projector in the junk cupboard, that you used to use for major presentations to clients and staff inductions, but has been replaced (and the plastic has gone yellow anyway) by the PDF and online assessment survey.
