THINK twice before you screw up that memo - however tempting it may be.

Environmental group Envirowise has created a 35 foot waste-paper aeroplane to launch a campaign aimed at reducing the amount of office paper used in the North-west.

The plane is made from the estimated amount of paper an office worker gets through in one month - an astonishing 1584 sheets of A4. This adds up to an estimated 2.3 billion sheets of paper used every month by office workers across the North-west, enough to reach the moon if laid end-to-end.

According to the government-funded organisation, paper use is rising by around 20 per cent every year.

Envirowise Regional Agent for the North West, Todd Holden, said: "Wasting paper is not only a drain on our environment but is also a burden on most companies bottom line - they are wasting money with every piece of paper they use needlessly.

"There is tremendous scope for reducing waste in offices."
