DuPont termina la expansión de la instalación que produce su biopolímero Sorona en Carolina del Norte

By -


Tipo de entrada: NOTICIA BREVE.

DuPont Industrial Biosciences produce su polímero parcialmente biobasado Sorona® en una instalación en Kinston (Carolina del Norte, USA). Este material se fabrica a partir de ingredientes renovables de origen vegetal en una proporción del 37%. Bajo esta marca comercial, se esconde el tereftalato de politrimetileno (PTT, por sus siglas en inglés): un copolímero del 1,3-propanodiol (obtenido por fermentación en el caso de Sorona) y el ácido tereftálico (de procedencia fósil en el caso de Sorona). Según DuPont, cuando lo comparamos con un polímero como el nylon 6, la producción de Sorona necesita un 30% menos de energía y libera un 63% menos de emisiones de gases de efecto invernadero. Las fibras fabricadas con Sorona se afirma que son suaves y extremadamente resistentes a las manchas, a la vez que muestran una alta resistencia y rigidez.

DuPont Industrial Biosciences ha terminado recientemente la expansión de la planta de producción, incrementando la capacidad para producir Sorona en un 25% (véase nota de prensa, 6/9/2018). La inversión es un reflejo de la creciente demanda de este biopolímero en los mercados de la confección y las moquetas y un enfoque global emergente en la economía circular. La empresa emplea más de 90 personas en Kinston y, con el arranque de la nueva línea, cuatro empleados adicionales están siendo reclutados.

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...
