• Might tree roots, twigs and branches one day be used to power cars?
  • That’s what a Swedish researcher is hoping after developing a pulp byproduct that — on a modest scale — does just that.
  • Chemical engineering scientist Christian Hulteberg, from Lund University, has used the black liquor residue from pulp and paper manufacturing to create a polymer called lignin.
  • After purification and filtration, that is then turned into a petrol mixture.
  • We’re actually using the stuff of the wood that they don’t use when they make paper and pulp
  • It adds value to low-value components of the tree.
  • In environmental terms, he says that gives it an advantage over other biofuels such as ethanol.
  • A lot of the controversy with ethanol production has been the use of feedstock that you can actually eat.
  • Mr. Hulteberg has a pilot plant in operation and hopes the forest fuel will be available in service stations by 2021.
