PORTLAND, Ore. -- An Oregon commission has ordered a waste-to-power facility to stop accepting boxed medical waste after learning it might be using the remains of aborted fetuses from British Columbia to generate electricity.

Sam Brentano, chairman of the Marion County board of commissioners, said late Wednesday the board is taking immediate action to prohibit human tissue from future deliveries.

The British Columbia Health Ministry tells The Associated Press that regional health authorities there have a contract with a company that sends biomedical waste, including fetal tissue, to Oregon, where it's incinerated in the waste-to-energy plant

Vancouver-based B.C. Catholic newspaper identified the plant as Covanta Marion, based in Marion County.

The facility processes about 500 tonnes per day of municipal solid waste, generating up to 13 megawatts of energy sold to Portland General Electric.
