Hey. I'm a huge fan of the show, but let me get right to the suggestion.
I worked at a grocery store for a couple of years and every couple of weeks, a specific event would occur that made my nose cringe at the very thought of. I'm talking about when this guy would come to collect all the fat/scraps from the meat department. I have never smelled anything in my life worse than that smell.
Now, while I've never seen anything beyond the collection of the scrapings, I'm assuming somewhere down the line, it's some unfortunate person's duty to seperate plastic and other foreign objects from the product. I've been told that it's ultimately tunred into cosmetics and such.
Using the information I remember, I found the website for the company responsible for collection and processing of this putrid material. Feel free to check it out and see if they can arrange something. It would be cool. I've always wondered the about the life cycle of that stuff. Here's the link:
And I would now like to apologize for my typing mistakes. I'm half asleep. Also, if my above suggestion has already been considered/used, maybe look into the duties of someone who works at a paper mill or something.
