China scientists make breakthrough turning stalk to bio-oil

Chinese scientists have claimed to have made a breakthrough in reducing the cost of converting crop stalks, chaff and sawdust into bio-oil, an alternative source of energy.

Bio-oil produced with the scientists’ technology is 56.8 per cent cheaper than diesel oil and 39.1 per cent cheaper than heavy oil, said Professor Guo Qingxiang of University of Science and Technology.

However, that bio-oil only produces two-fifths of heat from the same amount of diesel oil and only half that of heavy oil, Guo said.
