A Norfolk recycling company is creating pictures from crushed mobile phone covers to reduce the amount of phones dumped in landfill sites.
Cellular Surplus in Wymondham - which pays charities for used-phones - said some mobiles contained substances which could be toxic to the environment.
To cut down on waste some handsets are crushed under high pressure and displayed on canvas.
The firm also repairs faulty handsets and repackages phones for resale.
A spokesman for the company - which also manufactures pens and rulers from phones - said it was determined to operate a zero landfill policy.
