Greenbelt Resources and New Age Renewable Energy team up for converting dairy processing wastes into bioproducts

Type of post: NEWS IN BRIEF.

Greenbelt Resources Corporation (Greenbelt) and New Age Renewable Energy, LLC (NARE) have announced a technology collaboration agreement to provide a cost-effective solution for converting dairy processing wastes into bioproducts.
Press release: “Greenbelt Resources and New Age Renewable Energy Team Up for Joint Project Sales Collaboration”, 2/7/2019.

NARE (a privately held upstate New York based company) has developed a formulation to convert acid whey, whey permeate and other milk derivatives into bioethanol and a high quality protein concentrate.  However, adoption of the technology has been challenged by supply chain issues, scalability and operational expenses. Collaboration with Greenbelt resolves those challenges. Greenbelt’s modular design (ECOsystem) enables low cost operations and provides an ideal platform for incorporating the innovative fermentation formulation developed by NARE. The result is a low-energy-footprint, automated, modular, cost-effective solution that helps improve a dairy processor’s sustainability profile while also saving them money.

According to the USDA, every year over 3 million tons of soft dairy products (yogurt, cottage cheese, cream cheese…) are produced across USA. By NARE’s calculations, converting the cumulative total of only the acid whey waste (one of several waste types generated) would produce nearly 33 million gallons of ethanol and 10 million kilograms of yeast feed per year.  Each ECOsystem solution would likely have a capacity between 400,000 and one million gallons of ethanol production per year. Currently the industry estimates less than 15% of acid whey waste is diverted into anaerobic digesters. The rest is spread over land releasing carbon into the air as it decomposes.

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...
