Turn your notebook to loo paper!

Japanese scientists have come up with a new method of recycling paper waste - by turning it into toilet paper.

The machine, which weighs 94 stone, only takes 30 minutes to turn 40 sheets of A4 paper into a loo roll.

The paper is fed into a shredder on the machine, dissolved, thinned out and dried, and wound into toilet rolls.

The inventors reckon their invention can save 60 cedar trees a year.
