Lignin based materials and methods of making those

摘要

The present invention relates to plastic materials comprising lignin and poly(butylene succinate) (PBS) to methods of manufacturing those plastic materials and to articles obtained by molding the plastic materials of the invention. Since PBS can be obtained from renewable sources, the present invention also provides for bioplastic materials comprising lignin and PBS. The present invention also provides for plastic materials comprising lignin and PBS and at least one fiber and to articles obtained from those plastic materials that are degradable, compostable and recyclable.
