• Plaxica was a technology licensing company founded in 2008 as a spin-out from Imperial College, London to commercialise the research in PLA and lactic acid technology from the laboratory of Dr Ed Marshall and Professor Vernon Gibson.

    Between 2008 and 2017 Plaxica developed and commercialised three patented technologies in the renewable chemicals field:

    Xylex technology takes waste streams from the forest products industry and converts them into valuable hydrolysed sugar-rich streams rich in C5 sugars, whilst removing and isolating lignin.

    Versalac technology is a novel approach to racemic lactic acid production using a chemical process.  The feedstock includes, but is not limited to, the Xylex products.

    In August 2017, Plaxica sold the Xylex and Versalac technology to Sappi Limited – and the majority of the Company’s employees located at the Wilton (UK) Technical Centre transferred to Sappi’s employment.  Sappi is the leading global producer of speciality cellulose.

    Optipure technology produces optically pure ‘L’ and ‘D’ lactic acid from racemic lactic acid and lactides using an enzymatic resolution process.  In addition Optipure can convert ‘L’ lactic acid into ‘D’.

    In May 2017 Plaxica licensed the Optipure technology to the world’s leading PLA producer, NatureWorks LLC – and completed a sale of the technology to NatureWorks in December 2017.

    Having successfully achieved its objective of developing and commercialising its technologies with strategic customers who are best placed to implement the technologies, Plaxica ceased trading in December 2017.

    Plaxica’s Board would like to thank the many people – our suppliers, partners, customers and most importantly our talented and dedicated staff – who joined us on this journey.

    Questions relating to the Xylex and Versalac technologies should be directed to Sappi.

    Questions relating to the Optipure technologies should be directed to NatureWorks.
