Anellotech achieved new milestones at its pilot plant in Texas to make renewable PET resin


Houston, Texas

US sustainable technology company Anellotech recently achieved new milestones at its TCat-8® pilot plant in Texas, thereby progressing its 100% bio-based bottle collaboration with global consumer beverage company Suntory.

Anellotech’s TCat-8® pilot plant is using Bio-TCatTM technology, an efficient thermal catalytic process which converts non-food biomass feedstock material into BTX aromatics, a group of renewable chemicals identical to their petro-based counterparts. The first shipment of BTX has now been sent to joint development partners IFPEN and Axens for purification studies to make bio-paraxylene – the key aromatic chemical needed to make 100% renewable beverage bottles a reality. Bio-paraxylene from TCat-8® will be used to make renewable PET resin for prototype bottle manufacture and product testing.

Since the announcement of a successful two-week continuous pilot plant trial in March 2018, over 1,200 hours of cumulative on-stream time have been achieved at TCat-8®, while BTX has been generated for product testing and evaluation and process development data collected for future commercial plant design. Anellotech also continues to produce other aromatic products through its Bio-TCatTM process, including benzene and toluene. These can be used to make a range of bio-based polymers such as nylon, polycarbonates, acrylonitrile butadiene styrene (ABS) and industrial chemicals such as LAB (linear alkyl benzene), which is used in laundry detergents.

“Following our announcements earlier this year on process development and continuous operation – David Sudolsky, President & CEO of Anellotech, said – we are glad that significant progress continues at our TCat-8® pilot plant. We continue to move the technology towards commercialization, and shipping the pilot plant’s product for downstream evaluation is another major milestone. Having collaborated with Suntory since 2012 to advance development of cost-competitive bio-aromatics, we hope bio-based plastics made from our Bio-TCatTM process and a 100% bio-based bottle soon become a reality.”
