Plastic is one of the most important technological discoveries of the 20th century.However，it may soon be replaced.The new development—liquid wood—can replace plastics in all branches of modern industries.

Plastic as a material enjoys the biggest demand in the modern world，but it does have a number of drawbacks.First and foremost，plastic isn’t recyclable.Secondly，it contains toxins (毒物) helping develop cancerous diseases.Finally，it’s made of oil and oil reserves aren’t endless.

The? liquid wood technology is likely to replace plastic and provide mankind with new materials for many years ahead.Norbert Eisenfreich，a senior researcher at? the Faunhofer Institute for Chemical Technology (ICT) in Germany，said that arboform，the new material，is made of lignin (木質(zhì)素)，which can be obtained from soft tissues of wood.Once mixed with several other materials，it turns into solid and non?toxic alternative for plastics.

ICT team leader Emilia Regina Inone?Kauffmann said the wood?working industry separates wood into three basic components，including lignin.Lignin isn’t used for the production of paper.Specialists of ICT mixed lignin with several natural materials and thus invented the material which could be melted and molded (鑄型)．

When solid，arboform looks like plastic and possesses the qualities of polished wood.It can be used for the production of any items.Arboform is already used for the production of car parts which require extra strength.In addition，liquid wood can be recycled repeatedly.The material preserved all of its qualities even if it’s reprocessed ten times.

However，the new invention doesn’t enjoy an extensive use due to the high content of sulphur (硫) in it.German researchers are sure to reduce the amount of sulphur by 90 percent very soon to make arboform usable for home needs.
