Renewable Plastic Bottles Anellotech Partners with Ifpen, Axens to Produce Bio-Based Paraxylene
Bio-based paraxylene is one of the vital elements for developing 100 % bio based PET bottles. The companies have recovered high-purity bio-based paraxylene by processing renewably-sourced aromatics made at Anellotech’s TCat- 8 pilot plant.
Paris/France – Sustainable technology company Anellotech and its joint development partners Ifpen and Axens have processed renewably-sourced aromatics made at Anellotech’s TCat- 8 pilot plant to successfully recover high-purity bio-based paraxylene – a key component for making 100 % bio based PET bottles a reality.
This is a key development milestone for Anellotech and global consumer beverage company Suntory, as the two partners will collaborate to produce the bottles. Anellotech, Ifpen and Axens will now purify additional paraxylene to create pilot sample 100 % bio PET beverage bottles – as well as sample quantities of bio-based benzene whose derivatives (nylon, ABS, polycarbonate, linear alkyl benzene) are used in clothing, toys, mobile phones and laundry detergent.
Anellotech has been producing renewably-sourced aromatics for purification by Ifpen and Axens in Europe. Since the announcement of a successful two-week continuous trial in March 2018 at Anellotech’s TCat-8 pilot plant at Silsbee, Texas, over 4,000 hours of cumulative on-stream time have been achieved.
An initial volume of high-purity bio-paraxylene test samples has been produced. These samples have completely met all of the ASTM International specifications for downstream derivatives in conversion to PET. As larger amounts of paraxylene are purified, Anellotech will begin to make renewable PET resin for prototype bottle manufacture and product trials. This will be the industry’s first major production of bio-PET from continuous, cost-effective processing of non-food biomass.
Anellotech continues to work on the recovery of bio-benzene and toluene from TCat-8 output. Separation and purification of high-purity bio-benzene will enable sample volumes of a range of important bio-based polymers such as nylons, polycarbonate, polystyrene and acrylonitrile-butadiene-styrene (ABS) to be produced.
