Czech researchers develop method to produce biodiesel from tannery waste

In the Czech Republic, researchers at Tomas Bata University are working with the fat leftovers from leather production called fleshings to produce biodiesel from an otherwise toxic waste. Burning fleshing releases dioxins and nitrogen oxides, leaving few options for disposal, but now by melting down the fat to reduce the high levels of proteins and free fatty acids, biodiesel can be produced.
