Technology

 

Greenyug, LLC develops best in class manufacturing technology for commercial production of renewable commodity chemicals, specialty chemicals, polymers and fuels. Our capabilities include all aspects of technology development from concept at lab scale to piloting and commercialization. Our world-class team includes chemists, chemical engineers, technologists, scale-up specialists, and seasoned business leadership. Our corporate office and research lab is located in Santa Barbara, California and engineering/scaleup facility is located in India.

 

Process development plays an important role in the successful product development for specialty chemicals, pharmaceuticals, agrochemicals, and other “process enabled” business ventures. Most strategic decisions are made very early in the life of a project. There is increasing pressure on reducing the development time of new products and processes. Process development is usually performed in an evolutionary way in which the process flowsheet is developed based on experience, and proven ‘best practice,’ rather than on a systematic framework of generating process alternatives. The traditional approach is based mostly on years of experience with existing plants. Although this approach yields useful designs quickly and reliably, it does not promote the use of novel technologies nor does it allow for the comparison of alternative designs. Greenyug’s approach is to use hierarchical decision making to develop process technology in a systematic framework. Economic analysis at each stage of the development guides our technology to an economically and environmentally optimum process configuration. At Greenyug, we implement technology breakthroughs in chemistry and chemical engineering that enable us to manufacture renewable commodity chemicals, specialty chemicals, polymers and fuels at prices competitive with fossil based manufacturing processes.

An economically feasible project requires the right combination of feedstock/building-block/intermediate with an efficient process technology. Greenyug utilizes process development tools to enable rapid screening of process alternatives that enable us to focus on economically attractive combination of feedstock/building-block/intermediate and the process technology that enables highly profitable commercial implementation.
