Eastman anuncia planes para una planta de reciclaje de poliéster en Tennessee

By -

Tipo de entrada: NOTICIA.

Eastman Chemical Company ha anunciado planes para construir una instalación de reciclaje de plástico en su complejo de Kingsport (Tennessee, EEUU).

Figura 1. Botellas de PET de colores (extraída del comunicado de prensa)

A través de la metanólisis, la nueva planta utilizará más de 100 kton de desechos de poliéster que no se pueden reciclar con los métodos mecánicos actuales para producir plásticos fabricados con contenido reciclado. Este proceso no solo reducirá el uso de materias primas fósiles por parte de la empresa, sino que también reducirá sus emisiones de gases de efecto invernadero en un 20-30% en relación con las materias primas fósiles.

La metanólisis es un proceso en el que el metanol se combina con PET para promover una reacción química que lo descompone en monómeros, sus componentes básicos. Estos monómeros se utilizan para crear nuevos polímeros que son indistinguibles de los polímeros creados a partir de procesos tradicionales.

Durante los próximos dos años, la empresa invertirá aproximadamente 250 M$ en la instalación, que se espera que esté terminada mecánicamente para finales de 2022. Contribuirá a que la empresa logre sus compromisos de sostenibilidad para abordar la crisis de los residuos plásticos, lo cual incluye reciclar más de 500 millones de libras de residuos plásticos anualmente para 2030 a través de tecnologías de reciclaje químico.

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...
