Dirty nappies to be made into roof tiles

Dirty nappies will be turned into roof tiles when a recycling plant opens within the next year.
The recycling plant, the first of its kind in Britain, is expected to divert thousands of tonnes of waste that would otherwise end up in landfill sites.
Nappies processed at the facility will be turned into a range of products including roof tiles and plastic cladding.
The site will have the capacity to recycle about 30,000 tonnes of nappies and similar absorbant materials such as incontinence pads each year.
It is expected to open late this year or early in 2009 and will be built at a cost of more than pounds20 million in Birmingham by the firm Knowaste in partnership with Alpha Wastecare.
It it estimated that up to 750,000 tonnes of nappies - enough to fill Wembley Stadium eight times - are buried in landfill sites each year in Britain as part of 29 million tonnes of the nation's annual municipal waste.
Local authorities are under increasing pressure to reduce the quantity of waste sent to landfill. Each year until at least 2010 tax per tonne, now standing at pounds 32 for every tonne of waste, will rise.
