Toray and PTT Global Chemical Agree to Explore Mass Production Technology to Build Supply Structure for Non-Edible Biomass-Derived Nylon

Toray Industries, Inc., announced today that it has signed a memorandum of understanding with major Thai petrochemicals producer PTT Global Chemical Public Company Limited (GC) to explore mass production technology for adipic acid made from non-edible biomass*1.


Toray and GC will jointly evaluate the feasibility of mass production technology and commercialization in Thailand and Japan. If business is determined viable, they aim to commercially manufacture several thousand metric tons of bio-based muconic and bio-based adipic acid annually by 2030.

Last year, both companies began jointly developing technology to produce these raw materials for nylon-6,6 from non-edible biomass-derived sugars made at Cellulosic Biomass Technology Co., Ltd., a Thai company in which Toray has an 84% stake.

GC employs its proprietary fermentation technology to quickly convert non-edible sugars into high yields of muconic acid. Toray uses its hydrogenation process to produce high yields of high-purity bio-adipic acid from muconic acid. The resulting bio-based adipic acid can serve as a raw material for nylon-6,6 for resins and fibers similar to the petroleum-derived nylon-6,6. On top of that, the manufacturing process does not generate nitrous oxide, a greenhouse gas by-product typically associated with chemical synthesis-based processes.


Toray and GC will build a supply chain to manufacture tens of thousands of metric tons of bio-based adipic acid from agricultural waste in Thailand, which is rich in natural resources. They will use this acid to make eco-friendly nylon-6,6, assisting efforts to create a circular economy and lower greenhouse gas emissions.

The Ministry of Economy, Trade and Industry selected this study for its fiscal 2023 supplementary subsidy for the Global South Future-oriented Co-creation Project (Survey on the Promotion of Overseas Development of Infrastructure by Japanese Companies).

Toray is engaging in R&D, such as to develop technologies to switch to biomass-derived materials. It seeks to reach a 20% recycling rate for raw materials it uses in its core polymer offerings by 2030 and thereby help materialize a sustainable, circular economy in keeping with its commitment to delivering new value and contributing to social progress.

Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.

Today's KNOWLEDGE Share:High and low shear rate changes in Rheology

Today's KNOWLEDGE Share If a relatively high Mw grade flows from thin to thick, as shown in the picture, and if the time needed to fill the thick section is way shorter than the average polymer relaxation time, the polymer will not be able to reach its higher viscosity (corresponding to higher thickness/lower shear-rate). I am assuming here the polymer reached equilibrium low viscosity in the thin section, say for instance because it is much longer. Any pressure prediction not accounting for transient rheology would then overpredict the pressure to fill.Of course the diverging flow will further complicate the situation and mess with the molecular orientation created in the thin section, but to what extent ? Since this is more of a reasonable "conjecture", don't take this for granted, and discuss or share your opinion in the comments. There are hundreds of Rheology papers on the "4:1 contraction flow". Not sure I have ever seen any on the..."1:4 expansio

Bibby Marine Orders First Battery and Methanol Powered eCSOV

  A shipbuilding contract has been completed for what is being called the “world’s first truly zero-emission, electric Commission Service Operation Vessel,” which is being built as part of UK sponsored demonstration project. The ship is expected to enter service in the UK in 2026 using a combination of a powerful battery system along with dual-fuel methanol engines. A coalition of leading maritime companies led by Bibby Marine proposed the project as part of the UK’s Zero Emission Vessels and Infrastructure (ZEVI) project staged by the UK Department of Transportation. A total of £80 million was awarded to 10 projects in the 2022 round with the Bibby effort being   awarded   $25 million. They estimated the cost of the project for the vessel at $37.5 million total. Bibby Marine reports that it completed a tender process and has selected Gondan to build the vessel. The Asturias shipyard in Spain won out of a variety of yards in the UK and internationally. Bibby cites the timeline, budget,
