WILTSHIRE Wildlife Trust has begun a war on waste as schools start to compost their school dinners.

Instead of being thrown away, unfinished pasta or chunks of French bread and food scraps can by put into Green Johanna compost bins and turned into compost for their grounds.

The three foot tall bins are being provided free to schools by Wiltshire County Council and come with special jackets to raise the temperature high enough to compost up to three tonnes of waste a year.

Rowde Primary School headteacher David Ball is enthusiastic about the scheme and said: "We've got an active gardening club and the old compost bin is always full to overflowing.

"Our children will run the simple recording system and the whole scheme helps them understand more about how we can help the environment."

Residential centres such as CARE in Rowde have also received bins.
