Anellotech, a sustainable technology company focused on producing cost-competitive renewable chemicals from non-food biomass, and Japanese beverage company Suntory Holdings Limited have entered into next phase of strategic partnership to develop 100-percent bio-based plastics for sustainable beverage bottles.
The partnership, which began in 2012 under a collaboration agreement that has provided more than $15 million in funding to date, is focused on advancing the development and commercialisation of cost-competitive 100 percent bio-based plastics for use in beverage bottles as part of Suntory’s commitment to sustainable business practices. Suntory currently uses 30 percent plant-derived materials for its Mineral Water Suntory Tennensui brands and is pursuing the development of a 100 percent bio-bottle through this partnership.
The Anellotech alliance with Suntory supports the development of bio-aromatics including bio-paraxylene, the key component needed to make 100 percent bio-based polyester (polyethylene terephthalate, or PET) for use in beverage bottles. As an integral component in the bio-based value chain, Anellotech’s proprietary thermal catalytic biomass conversion technology (Bio-TCatTM) cost-competitively produces ‘drop in’ green aromatics, including paraxylene and benzene, from non-food biomass.

“By focusing on the development of substitute materials to replace petroleum in making everyday consumer products, we are expanding our commitment to reduce the environmental burden of beverage packaging, including reduction of CO2 greenhouse gas emissions,” said Munehiko Takada, head of packaging material development department at Suntory.
Suntory joins Anellotech’s existing partners IFP Energies nouvelles (IFPEN), Axens, Johnson Matthey, and a multinational corporate investor, which has provided a $7 million equity investment, the first tranche of a total $10 million investment.
“We are pleased to enter the next phase of our partnership with Suntory and further advance our technology to meet growing consumer demand for products and packaging made from sustainable sources. With Suntory’s focus on bio-paraxylene, Anellotech can now offer a unique opportunity to new partners interested in bio-benzene-chain derivatives. This includes nylon, polycarbonate, linear alkyl benzene for laundry detergent, and styrene for styrene butadiene rubber,” said David Sudolsky, President and CEO of Anellotech.
By starting from cost-advantaged feedstock and employing a solid catalyst in just one fluid-bed reactor, Anellotech’s process can produce the 100 percent bio-based aromatic chemicals that are used to make many significant plastics. By going directly from biomass to BTX in this one reactor, Anellotech does not make a highly-oxygenated bio-oil intermediate product often seen in multi-step pyrolysis processes, and avoids the need to add substantial amounts of costly hydrogen.
Approximately 54 million metric tons of PET are manufactured globally each year. Despite strong industry demand, there is no commercially-available, bio-based paraxylene in the market at present. This has limited the ability to make 100 percent bio-based PET at commercial scale. By using Bio-TCat technology, Anellotech and its partners are accelerating the development of bio-based paraxylene and other widely-used chemicals including benzene, toluene and other xylenes (commonly known as BTX) from non-food sources. This will allow for the first cost-effective production and commercial realisation of 100 percent bio-PET bottles for consumer use.
The ultimate competitive advantage of Bio-TCat over fermentation-based technologies is derived from Anellotech’s use of a simple process performed in one reactor-catalyst system. Other than biomass and catalyst, there are no further inputs, apart from minor amounts of hydrogen used downstream of the reactor to remove trace impurities prior to further separation of the BTX. As a result, these bio-based aromatics can be sold profitably against their identical, petroleum-derived counterparts. Furthermore, because it uses renewable and abundant non-food feedstocks, such as wood, corn stover and bagasse, the Bio-TCat process is less expensive compared to those that use sugar-based feedstock, and avoids competition with the food chain.
