==Paper Shredder==
===Shredder scissors===
* Small, light, cheap,
* Convenient for minimal amounts of shredding
* Can cross cut or strip cut

===Manual shredder===
Ok for shredding a percentage of domestic mail

===Electric shredder===
* The most popular type of shredder
* Very wide range of units & prices

Properties
* Strip or crosscut - crosscut is more secure
* Size of strips or pieces
* Number of sheets taken in one go
* Speed of shredding
* How it handles staples (jams, stops, passes them whole or shreds
them)
* Some also chop CDs and credit cards
* How it handles jams - some automatically reverse feed to clear a
jam.

Shredded paper is used for animal bedding, and can often be given away
on freecycle etc.

===Alternatives===
* burn
* microwave destruction of CDs


==Garden shredder==
Designed to shred tree prunings & sometimes weeds. Shredding turns the
prunings into mulch.

Properties
* Size limit - maximum wood size tends to be small with domestic
units, often around an inch. The biggest units can swallow whole
trees.
* [[Noise]] - most garden shredders are extremely noisy, making ear
defenders essential, and annoying neighbours
* Mechanism type - some behave better than others
* Blade replacement - usually blades are replaceable & cheap.
Generally they can be resharpened with an [[angle grinder]] several
times before replacement.

===Other uses===
Garden shredders can also be used to shred used [[carpet]] to make
fibres for concrete crackproofing. Clearly this is a use not
recommended by manufacturers, and may invalidate guarantees.
* Precut the [[carpet]] into diagonal strips. They need to be diagonal
to limit max thread length, otherwise the shredder mechanism may be
tied up & jammed.
* Doing this by hand is hard going, an [[Scissors|electric cutter]]
makes it easy.
* Feed the strips in one at once, it can be hard going for the
machine.
* Expect to need to open a jammed mechanism occasionally and cut
threads out.

The resulting mixed fibres can be added to concrete to increase its
tensile strength and counter cracking. Around 1% fibre is used for
this. Its also possible to use them with [[bitumen]] for roof repairs,
at a much higher percentage. Only synthetic fibres are recommended,
wool pile or canvas backing doesn't last so well. Finally its possible
to make a low grade fibre cement by mixing a high percentage of fibre
with [[cement]] & [[sand]].

It would be worth pointing out that if shredded paper is used for
animal bedding, you must ensure that staples or pins are removed, to
prevent injury to the pets.

And that the paper is just paper. Not sure what effects the chemicals
from thermal print paper (till, credit/debit card receipts etc) may
have on animals when they eat it.

And how about the ink?
When I was a child my mother used to make sandwiches on a clean
newspaper. When she disputed my claim that I had writing on my
sandwiches, I held a sandwich next to a mirror and read the news to
her.

I think printing ink is a little bit cleaner these days. To parallel
your story, when I was a child, we used to transfer newspaper pictures
into drawing books etc using a method akin to tracing. 1)Rub a wax
candle to cover one side of a sheet of tracing/greaseproof paper.
2)Place waxy side down on the newspaper and rub vigorously over the
picture you want to transfer. 3)Peel off then place waxy side down on
the drawing paper. 4)Rub vigorously again and the picture will
transfer. Sometimes there was enough absorbed ink in the wax to make
two or three transfers (fainter each time).

Donno, like the thermal paper. Just a heads up...

I remember having fish and chips wrapped in old newspaper.
