A friend of mine now works for a small bio-diesel plant and there primary source of oil is restaurants. They have been approaching restaurants and offering to buy their used fryolater oil in order to convert it into bio-diesel. This is taking the oil (in almost every case) away from a massive international company. This company certainly did nothing as "green", eco-friendly, or in anyway constructive. Nope, they take the used, nasty, burnt oil, filter it, and then sell it to the beef industry. Where it goes into cattle feed. And then you eat it.
Once again, please take the time to find a locally raised beef, chicken, and pork supplier. Also, as I have mentioned in the past, Hannaford Nature's Place sticker seems to be sourced from more responsible farms. A couple extra dollars spent will help a local business out and give you a much superior product.
