A New Source of Biofuel – Leather Sludge
(Reuters) 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.

This vat of grey sludge could hold a new supply of biofuel. A team of Czech scientists have found a way to convert the toxic byproducts of leather production into fuel. According to Professor Karel Kolomaznik from Tomas Bata University, it all starts with leftover fat parts called fleshings… (SOUNDBITE) (Czech) PROFESSOR KAREL KOLOMAZNIK, SAYING: “These are the fleshings which remain after the removal of subcutaneous ligament and fat. This tannery waste is the main source of biodiesel production.” Fleshings are also be a source of toxic waste, according to Kolomaznik. But thanks to the method that he and his team have developed, the fleshings are refined into fuel instead of becoming an environmental hazard. READ MORE
