Germany touts wood residue, straw and sour milk as biofuel sources

Rapeseed and sugar cane are out, making way for wood, straw and curdled milk to play key roles as future biofuel energy sources that would not starve the planet by taking over land need for food. German Chancellor Angela Merkel was on hand Thursday with the heads of automakers Daimler and Volkswagen to inaugurate what was billed as the world's first refinery of "second generation" biofuels in the eastern city of Freiberg. Merkel hailed the "hand-in-hand work by the political, economic and scientific sectors." The Choren group hopes to produce 18 million litres of biodiesel carburant there each year using wood residues. Its project has high-profile backing from Anglo-Dutch energy giant Shell in addition to the two world-class German auto manufacturers.
