Sorting Business or waste to Fuel?

I have grave concerns regarding the feed stock.

What the specifics of the agreements are with suppliers, what the allowed tolerances are in those agreements, what is the course or action when the feed stock is contaminated, what is the agreement and process to dispose of out of spec feed stock and how IGES will dispose of the unwanted waste they sort.

The more I think about this the more concerned I am. Especially taking into account that this is their first attempt at recycling. I'm hoping that the agreements are of high value and air tight in this regard and that the sorting machines that they are putting a high emphasis on in announcements are simply a final precautionary measure before the feed stock enters the machines. This could spell disaster for the company if not right.
