technology produces low cost lactic acid from a variety of bio-feedstocks.
Versalac® is a continuous chemical process with fast reaction times and the
lowest variable cost of any available commercial lactic acid technology. Unlike
fermentation, the process is tolerant of many chemical impurities including
lignin and other materials.
Versalac® is proven to
give good yields of lactic acid from many feedstocks including forestry,
agricultural and industrial by-product streams. The process is robust and uses
proven, widely available, materials and technologies. Implementation of Versalac® technology is
tailored to your application and designed on a site specific basis. This
approach maximises integration opportunities and process synergies which
enables partners to realise the maximum return on their investment.
technology is a robust, scalable chemical process which separates racemic
lactic acid into valuable pure L & D isomer streams which are suitable for
processing into high performance polylactic acid (PLA). Optipure® adds
significant value to racemic lactic acid at very low cost.
The Optipure® process
can be configured to produce D lactic acid from L lactic acid and also to
produce D lactic acid from PLA production waste streams such as meso lactide
& lactic oligomers.
Low cost L & D
lactic acids can be used to produce high performance polylactic acid with
enhanced thermal, barrier and mechanical performance. These enhanced properties
give PLA access to high volume commodity polymer markets such as automotive,
apparel and consumer goods.
The Versalac® process
converts low cost sugar feedstocks into lactic acid at a cost which results in
a viable C3 intermediate.
Optipure® is a novel,
low cost proprietary technology for converting racemic lactic acid (50-50 L
&D), or pure L-lactic acid into D-lactic acid. D-lactic acid can even be produced from low
purity waste lactic acid or lactide stream such as meso lactide.
focuses on low cost, non-food sugar sources.
It will work with non-fermentable sugars (C5, C6)
