The purple-pink plume was first spotted rising from the Ecomaine stack at the Blueberry Road facility on Thursday morning. Ecomaine officials said the issue was fixed within a couple of hours and was believed to be caused by a larger-than-normal amount of iodine in the waste stream.But the purple vapor returned Friday morning and this time appeared more vibrant against cloudy skies. It could be seen as far south as Scarborough.Nate Cronauer, a company spokesperson, said workers noticed the purple vapor around 8:30 a.m. Friday and immediately stopped feeding trash into the boiler.“We’re confident it is purple vapor coming from a source of iodine that came in through the waste stream,” he said.In a statement Friday, Ecomaine CEO Kevin Roche said, “While we’ve been able to identify what we believe is causing the problem, we have not yet been able to identify the source of where this waste is coming from.”The company, which generates electricity by processing waste, said in the statement that the incident “serves as a clear reminder of the importance of making sure municipal solid waste is disposed of correctly.”
So I'd really like to know what typical household or industrial solid waste contains a bunch of iodine? Is it film? A bunch of rotten seaweed?
