In the quest for alternative fuels, it seems that there will be a new use for rendered animal fats. Tyson Foods, a large food conglomerate with big interests in poultry especially, is working with Conoco Phillips to develop diesel fuel products from rendered animal fats.

While acknowledged not to be a major fuel alternative, just think what might happen if a fast food chain like McDonalds started a conversion program similar to this one? A chain of fuel stations entirely supplied with McGas and McOil?

I wonder if animal fats can be traded as a commodity?
