Covestro opens CO2 to plastics plant production in Dormagen

By -


One of the key points with regard to the fight against global warming is the need to reduce emissions of CO2 gas. Many innovative companies are looking at ways to re-use CO2 as a resource to make products such as fuels, chemicals and plastics. This is the case of Covestro and the Dream Production project.

Together with partners in industry and research, Covestro tackled the challenge of developing a process to produce high-quality plastics from CO2 and, finally, it is using this process on an industrial scale. At its site in Dormagen (Germany), Covestro has just inaugurated a production facility to manufacture a polyol containing about 20% of CO2 with this new method (see the press release). Polyols are precursors of flexible polyurethane foam, found in many everyday items. In terms of quality, the foam achieves at least the same standards as conventional material produced using only petrochemical raw materials.

The company has invested €15 million in the new plant, which has an annual production capacity of 5 kton. The CO2 used is a waste product from a neighboring chemical company. If the new CO2-based products are received as warmly as is hoped, Covestro can envisage significant production expansion. In addition to flexible foam, the company is also working on manufacturing many other plastics with CO2.

This achievement was made possible by first finding the right catalyst. Otherwise, the process would not have been practical either economically or ecologically. It is a breakthrough innovation that will enable the company to widen is raw materials basis and reduce petroleum consumption. Covestro scientists worked hand-in-hand with experts from the CAT Catalytic Center of RWTH Aachen University to find this right catalyst.

Recently, Covestro presented its technology as a contribution to resource conservation in the park of Schloss Bellevue (the German President's residence) during the ‘Week of the Environment’ in Berlin. A total of 200 exhibitors from the business, science and public sectors had sustainable initiatives on display at the event. Concurrent with this exhibition, the ‘Dream Production’ project was selected by Sustainia (a Danish think tank specialized on sustainability) from over 1,200 candidates as one of the top 100 most sustainable projects of 2016.

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...
