Queen's scientists discover eco-friendly wood dissolution http://apocadocs.com/s.pl?1242838992
Scientists at Queen's University Belfast have discovered a new eco-friendly way of dissolving wood using ionic liquids that may help its transformation into popular products such as bio fuels, textiles, clothes and paper.... At present wood is broken down mainly by the Kraft pulping process, which originates from the 19th century and uses a wasteful technology relying on polluting chemicals.... The Queen's researchers found that chips of both softwood and hardwood dissolved completely in ionic liquid and only mild conditions of temperature and pressure were needed. By controlled addition of water and a water-acetone mixture, the dissolved wood was partially separated into a cellulose-rich material and pure lignin.
This process is much more environmentally-friendly than the current method as it uses less heat and pressure and produces very low toxicity while remaining biodegradable.
