How do you have fun, keep fit and help the environment all in one go?

Just ask pupils at Sutton-upon Derwent Primary School who are using the newly-developed Composphere, manufactured by Crompton Mouldings.

The sphere is made of recycled polyethylene and can hold 315 litres of compost.

The children take it in turns to rotate the compost by rolling the huge sphere around the school field.

The movement aerates and tumbles the compost.
