Production of bio-PET, starting with bio p-Xylene from the Bio-TCatTM technology of Anellotech through the subsequent downstream separation, purification, intermediate PTA (purified terephthalic acid) and final PET steps, was the last milestone to completely validate the Bio-TCatTM technology for the production of prototype 100% bio-based bottles. This follows more than 5000 hours of successful TCat-8® pilot plant operation using pine wood feedstock to produce tonnes of BTX aromatics. To date, enough of the produced bio paraxylene was separated to allow potential production of more than five thousand (5000) 100 % bio-based Plastic 500 ml bottles, while fully meeting polymer grade specifications.
This achievement by Anellotech and its joint process development alliance partners, IFPEN and Axens, affirms their commitment to innovative production of cost-competitive renewable chemicals. Anellotech also partnered with Johnson -Matthey for the Bio-TCat catalyst development. Anellotech’s TCat-8® pilot plant, built to develop the Bio-TCatTM technology, demonstrates the performance of this efficient thermal-catalytic process which converts non-food renewable biomass feedstocks into aromatics. The Bio-TCat™ process will enable aromatic chemical producers and brand owners to meet environmental, sustainability product goals, due to its low carbon footprint and its non-food renewable biomass feedstock. Bio-TCatTM benzene can be used to make a range of bio-styrenics, nylon, and polycarbonate, while Bio-TCatTM toluene can be used for production of polyurethanes.
Discussions are underway by Anellotech and its exclusive licensing partner Axens to commercialize the Bio-TCat Process, by identifying potential partners (including off-take) and a plant location for a first 500 tonne/day feed rate commercial plant. A “white paper” process design package has already been completed by Axens for adaptation to the actual plant site, once selected.
“The competitive advantage of Anellotech’s Bio-TCat generated paraxylene is its process efficiency (it uses a single-step thermal catalytic process by going directly from biomass to aromatics (benzene, toluene and xylene)), as well as the opportunity it creates for a significant reduction in greenhouse gas emissions as compared to its identical fossil-derived paraxylene in the manufacture of PET, especially as it generates required process energy from the biomass feedstock itself” said David Sudolsky, President and CEO of Anellotech.
“We are extremely glad to announce this major step of our common development that fits in our goal to develop new technologies and products for a low-carbon economy. It shows that Bio-TCat BTX products can be used to make key polymers answering the needs of brand-owners for sustainable products and opening the road for sustainable processes to produce the main chemical intermediates “ said Jean Pierre Burzynski, Process Business Unit Director at IFPEN.
“I am delighted to announce this major achievement. It validates the bio-paraxylene produced by the Bio-TCat process showing the growing interest of the market for sustainable products and open the way for the realization of the first commercial plant. This is part of our strategy to accelerate the deployment of bio-based products and to reduce substantially the GHG emissions of the chemicals value chain. ” said Pierre Beccat, CTO of Axens.
