NaturALL Bottle Alliance (Danone, Nestlé Waters and Origin Materials) to build a pioneer bio-PET plant

By -


Important initiative driven by the packaging sector with major implications for the growth of the biopolymers industry. Danone and Nestlé Waters, the world’s two largest bottled water companies, have joined forces with Origin Materials, a startup based in Sacramento (California) to form the NaturALL Bottle Alliance (see press release). Together, the three partners aim to develop and launch at commercial scale a PET plastic bottle made from 100% sustainable and renewable resources. The Alliance partners consider that everyone should benefit from this new material, demonstrating their commitment to open innovation and sustainable business. Danone y Nestlé Waters are providing expertise and teams, as well as financial support, to help Origin Materials make this technology available to the entire food and beverage industry in record time. After identifying the approach of the Californian startup separately, the two large companies decided to team up to accelerate development of this promising technology (see the video below).


The thermoplastic polymer PET (polyethylene terephthalate) is a product of the polymerization of monoethyleneglycol (MEG) and purified terephthalic acid (PTA). Currently, these two monomers are almost entirely sourced from fossil sources. To date there are a few commercial efforts to produce bio-based MEG from ethanol. Bio-PTA, however, remains unavailable in the market. PTA is synthesized through the oxidation of isomerically pure paraxylene (PX).

Origin's technology produces biobased intermediates from lignocellulosic raw materials so it does not divert resources or land from food production for human or animal consumption. Those intermediates can be used to make new polymers, surfactants and carbon black. The company (formerly known as Micromidas) has developed a catalytic route to making PX from cellulosic biomass and ethylene. The process, which involves no fermentation, is cost-competitive with that of petroleum-derived PX.

Origin Materials has already produced samples of 80% bio-PET in its pilot plant in Sacramento. During this year, the Alliance will construct a pioneer plant to produce the first samples of more than 60% bio-based PET plastic by 2018. The R&D will focus initially on cardboard, sawdust and wood chips but other biomass materials, such as rice hulls, straw and agricultural residue could be explored. The initial goal for the first step is to bring 5,000 metric tons of bio-PET to the market. Thanks to the complementary skills and shared vision of its members, the NaturALL Bottle Alliance aims to develop the process for producing at least 75% bio-based PET plastic bottles at commercial scale as early as in 2020, scaling up to 95% in 2022. The partners will continue to conduct research to increase the level of bio-based content, with the objective of reaching 100%.

Recent news about one of the DOE’s 12 Top Biobased Molecules. Rennovia Inc. and Johnson Matthey Process Technologies announced on July 16 that they have successfully started-up a mini-plant for production of glucaric acid from glucose using jointly developed technology. In March 2014, these companies embarked on a collaboration to develop, demonstrate and commercialize catalytic process technologies for the production of bio-based glucaric acid and adipic acid. Under the collaboration, Rennovia and JM Process Technologies work together in processes based on Rennovia’s technology for the catalytic aerobic oxidation of glucose to glucaric acid and the catalytic hydrogenation of glucaric acid to adipic acid. The final goal of the collaboration is to license a package enabling commercial production of these chemical products. The successful operation of this mini-plant is a major milestone in the journey to achieve this goal. The facility is located at the Johnson Matthey Process ...

Publication date: 25/04/2016 Last update: 25/04/2016 ABOUT THE SERIES OF POSTS “BIOREFINERY MODELS” This post belongs to a series called “ Biorefinery Models ”. This series is devoted to briefly describe the models or concepts of advanced biorefineries which have emerged in the last few years and that are rising currently. These models are simplified representations which enable us to understand in a simple way the structure and characteristics of a general biorefinery type. Some of these models refer to the type of feedstock while other focus on the technologies involved. A biorefinery may resemble these models or be the result of variations and combinations of them. It should be noted that although these paradigms are very useful and instructive, they show limitations in describing and classifying complex systems with high level of integration. In order to define and describe a specific complex case, the blog recommends use the classification proposed by IEA Bioenerg...

English version Sección: BIOCOMBUSTIBLES AVANZADOS Serie: HVO - Hidrotratamiento (HVO) – Conceptos, materias primas y especificaciones - Hidrotratamiento(HVO) – Ventajas sobre el biodiesel convencional y propiedades - Biorrefinerías de Aceites Vegetales Hidrotatados (HVO) – El auge del diésel renovable - Entradas: HVO                El acrónimo HVO significa en inglés “ Hydrotreated Vegetable Oils ” (“Aceites Vegetales Hidrotratados”) o ” Hydrogenated Vegetable Oils ” (“Aceites Vegetales Hidrogenados”). Clave del proceso: Tratamiento con hidrógeno. En el proceso de producción de HVO, el hidrógeno se usa para eliminar el oxígeno de los triglicéridos produciendo una mezcla de parafinas lineales, CO 2 y agua. Posteriormente, el producto de la primera etapa se isomeriza, siempre en presencia de hidrógeno, para ramificar las cadenas lineales con el propósito de mejorar las propieda...

Biofuels from algae

In my opinion, the production of biofuels and biobased chemicals from algae is one of the most fascinating topics in the sector of the biorefineries and it will be one of the niches of opportunity with highest potential in the medium and the long terms. This post pretend to be a very basic approach to the topic Algae-to-Biofuels through three general key points. Algae 1,2,3,4,5 Algae include a wide variety of photosynthetic organisms capable of transforming light, water and specific nutrients into products that can be used with commercial and industrial purposes. We can say that algae are sunlight-driven factories with potential to convert CO 2 into biofuels, high-value biochemical, food and feed. There are four algae cultivation technologies currently in use for commercial algae cultivation and proposed for algal biofuel production: extensive or open ponds, intensive or raceway ponds, closed photobioreactors in many designs and closed fermenter systems. Algal biof...
