Greenmills es una iniciativa conjunta de Noba, Rotie, Biodiesel Amsterdam y Orgaworld. Los tres primeros forman parte del Simadan Group. Bajo este nombre, los socios usan los residuos de varios procesos (corrientes procedentes de los sectores alimentario, de las bebidas y del tabaco junto con aceites usados) como materias primas para generar biocombustibles y bioenergía. Se trata de una planta autosuficiente que produce su propia electricidad y calor y que también exporta a la red general. Greenmills is a joint initiative of Noba, Rotie, Biodiesel Amsterdam and Orgaworld. The first three are part of the Simadan Group. Under the name Greenmills, these companies use waste flows from various processes (streams from food, drinks and tobacco sectors as well as waste cooking oils and fats) as raw materials in order to generate biofuels and green power. It is a self-supporting plant that produces its own electricity and heat and that also supplies electricity to the main grid.

Rotie recoge, limpia y procesa aceites usados para convertirlos en una materia prima apta para la planta de Biodiesel Amsterdam. Por su parte, Orgaworld produce biogás en grandes tanques donde se digieren los residuos orgánicos de Rotie. El biogás es transformado en vapor, calor y energía. Una parte de estos productos es utilizada en el complejo de Greenmills (calentando el parque de tanques donde se mantienen los aceites fluidos y produciendo bioetanol) y el resto se libera en la red general. Noba produce aliementos ricos en grasas para la industria del pienso. Los productos residuales generados en los distintos procesos se transforman en fertilizantes de alta calidad. Greenmills produce en un año 25 millones de m3 de biogas, 113 millones de litros de biodiesel y 5 millones de litros de bioetanol. Waste cooking oils are collected, cleaned and processed further by Rotie to turn them into suitable raw materials for the Biodiesel Amsterdam plant. Orgaworld processes the organic waste material stored at the Rotie factory in large tanks to release biogas. The biogas is converted into steam, heat and green energy. These products are partially used by Greenmills (heating the tank park that keeps oil fluid and producing bioethanol) and the rest is released to the power network. Noba produces energy-rich fat products for the animal feed industry. The residual product left over from the processes is transformed into high-quality fertilizer. Grenmills produces in a year a total of over 25 million m3 of biogas, 113 million litres of biodiesel and 5 million litres of bioethanol.

Mini-plant for production of glucaric acid from glucose starts up successfully

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 ...

Biorefinery models - Lignocellulosic biorefinery

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...
