Donate Turkey Fat

So, while not a tradition in my family, it is common in the south to deep fry turkeys for Thanksgiving. Not a fan of fried foods, this sounds disgusting to me. However, for those that do and live near me, evidently my city of Plano accepts donations of turkey fat to be turned into biodiesel. And from what I can find with my limited internet skills, Plano seems to be the only city that actively does this. How strange?
