The bodies of thousands of aborted and miscarried babies were incinerated as clinical waste, with some even used to heat hospitals, an investigation has found.

Ten NHS trusts have admitted burning foetal remains alongside other rubbish while two others used the bodies in ‘waste-to-energy’ plants which generate power for heat.

Last night the Department of Health issued an instant ban on the practice which health minister Dr Dan Poulter branded ‘totally unacceptable.’

At least 15,500 foetal remains were incinerated by 27 NHS trusts over the last two years alone, Channel 4’s Dispatches discovered.

The programme, which will air tonight, found that parents who lose children in early pregnancy were often treated without compassion and were not consulted about what they wanted to happen to the remains

One of the country’s leading hospitals, Addenbrooke’s in Cambridge, incinerated 797 babies below 13 weeks gestation at their own ‘waste to energy’ plant. The mothers were told the remains had been ‘cremated.’

Another ‘waste to energy’ facility at Ipswich Hospital, operated by a private contractor, incinerated 1,101 foetal remains between 2011 and 2013.

They were brought in from another hospital before being burned, generating energy for the hospital site. Ipswich Hospital itself disposes of remains by cremation.
