Comment: If the contamination limit is .03 of 1%, that would seem to make even an empty pizza box unrecyclable, considering the melted cheese etc. stuck on the cardboard.  

This problem may indicate some hypocrisy in Oregon's ultra pro-environment community, which is the majority.  I certainly care about the environment, but I'm not part of the environmental rubber stampers, and do thoroughly wash my recyclables.   Maybe this article will wake-up some of these self-righteous people.
