MBA students’ visit from Montclair State University

MBA students from Montclair State University (Montclair, NJ, USA) have visited Soneas Research Ltd (Budapest, Hungary) at its Berlini site in 05-23-2016. During the event the Founder and Managing Direct of Soneas Research Ltd (formally Ubichem Research Ltd) József Répásai, held a lecture about the history of the company, its present and future opportunities and challenges at the European and Global market as a successful R&D and chemical manufacturer service provider. The lecture was followed by a guided tour at the R&D facility and a free question and answer session with Mr. Répási.

Mr. Répási is always looking for opportunities to educate students from wide area of sciences and his lectures are informative and stimulating, where free discussion is always welcome.

We received several feedbacks from the attendance so far. See the latest ones below.

“Dr. Repasi is a very passionate and inspiring speaker. Many students were impressed and inspired by his speech.  He loves what he is doing and is not afraid of challenges. Both the presentation and the lab visit were very well prepared. The research director, who did his post-doc study in USC, led the lab visit, and it was great.”

“The speaker was excellent and passionate about his company and research. The meeting and facility tour were set up nicely. Plenty of snacks and refreshments were provided for us.”

Partner Collaborations Advance Second-Generation Elevance Biorefinery Technology

Woodridge, Illinois, USA (Jan. 19, 2016) – In collaboration with several partners, including the special contribution of Versalis under a strategic partnership started in early 2014, Elevance Renewable Sciences, Inc. — a high-growth company that creates novel specialty chemicals from natural oils — has successfully completed scale-up of a second-generation biorefinery technology of the company’s olefin metathesis technology, utilizing ethylene and natural oil feedstocks.

The ethenolysis process advancement represents an important milestone for the development of a second-generation metathesis technology — the first of its kind — enabling an enhanced product portfolio from natural oils metathesis.

Catalysts produced by XiMo AG were used at Soneas’ manufacturing facility in Budapest, Hungary. The run represented a scale up of 40,000 times what had been previously demonstrated in the laboratory and the largest ever usage of “Schrock” (Molybdenum/Tungsten) catalysts for metathesis with ethylene and a renewable oil.

“This significant accomplishment advances the interests of several of our partners and demonstrates the advantages of working together,” said Mel Luetkens, COO at Elevance. “Elevance is pleased to be at the center of this collaboration and to be advancing these important developments for our partners and us. It is another validation of Elevance’s technology and the value that we bring to our partner relationships.”

XiMo AG, a company focused on the development and application of proprietary metathesis catalysts, and Elevance began working together in January 2011, carrying out successful demonstrations that make the Molybdenum- and Tungsten- catalyzed metathesis of natural oil esters commercially competitive. Soneas, formerly known as Ubichem Pharma Manufacturing, is a professional chemical service provider with pilot and commercial scale manufacturing facilities.

The advancement was partially funded by and supports a wider strategic partnership between Versalis, the chemical subsidiary of Eni, and Elevance that includes the joint development of Elevance’s ethenolysis technology. This takes advantage of Versalis’ extensive skills in catalysis process development and engineering design and Elevance’s proprietary know-how regarding metathesis and associated engineering with the use of vegetable oils in producing specialty chemicals for premium applications. Meanwhile, Versalis and Elevance have also been collaborating for the implementation at the Versalis Porto Marghera site of a biorefinery based on Elevance proprietary technology of natural oils’ metathesis with 1-butene.

“We strongly believe in the potential of metathesis technology since it is a mild reaction that does not destroy the molecular complexity of vegetable feedstocks, the highest value of them,” said Sergio Lombardini, Director of Research & Innovation Technology at Versalis. “This is why even in the engineering phase for a butene-1 metathesis plant, we are looking at ethylene as an alternative co-feedstock aiming to target an even higher value of products portfolio.”

The ethenolysis tolling run was also partially funded by a grant from the United States Soybean Board given to Elevance for metathesis of soybean oil products, which were used as feedstocks for this project.
