2014 Great Lakes Green Chemistry Conference – Innovating for Success in the Great Lakes

The 2014 Great Lakes Green Chemistry Conference – Innovating for Success in the Great Lakes Region – is taking place on April 1-2, 2014 in Cleveland, OH and there’s still time to register. This two-day conference will bring together businesses, researchers, state environmental agencies and NGOs to hear about how Green Chemistry and sustainable chemistry initiatives in the Great Lakes are driving innovations all along the supply chain. Keynote speakers include some of the most prominent names in the field of Green Chemistry. Our morning keynote  John Warner is the co-author of the landmark publication Green Chemistry, Theory and Practice, and is currently the president and chief technology officer at Warner Babcock Institute for Green Chemistry. He will talk about “Mechanisms from Nature in Materials Design”. Julie Zimmerman, our luncheon keynote, is the Associate Director of the Center for Green Chemistry and Green Engineering at Yale University, will speak about “Green Engineering:  Fundamentals, Sustainability, and Design”, and our final keynote on Tuesday morning will be Dennis McGavis, Global Director of EHS Sustainability at Goodyear Rubber & Tire Co. Dennis will be presenting on “Two big challenges for green chemistry innovation – from an industry perspective”.

Great Lakes Chemistry Conference

The conference will also include several dynamic panels and breakout sessions with opportunities to hear from companies on the cutting edge of innovation in the region, as well as from academic institutions such as the University of Toledo who has just opened their new School of Green Chemistry and Engineering. Panels will address the Imperative for Green Chemistry in the Great Lakes, How Policy Drives Green Chemistry Innovation,: The Business Perspective, Green Chemistry Innovations in Business, and Getting Started on Alternatives Assessments, followed by breakout sessions where participants will have the opportunity to engage in more in-depth discussion on issues raised with the panel sessions.

On April 1, the first night of the conference, the Great Lakes Green Chemistry Network, one of the conference sponsors, will host a dinner at the Mallorca Restaurant in Cleveland in honor of John Warner, to which all conference registrants are invited to make reservations.

More information and registration for the conference can be found at www.glrppr.org/conference/registration

Two additional events will also be available as part of the conference. On March 31, the Great Lakes Regional Pollution Prevention Roundtable will hold a half day meeting. Separate registration is required and more information is available from at Laura Barnes at l-barnes@illinois.edu. Immediately following the conference, on Thursday, April 3, there will be a one-day GreenScreen™ for Safer Chemicals Training. This is a training on the hazard assessment tool,  GreenScreen™  for Safer Chemicals, developed by Clean Production Action for identifying chemicals of concern and selecting safer alternatives. Separate registration is required, and more information is available by contacting greenscreen@cleanproduction.org

Combining Carbon Dioxide Capture and Cellulose Dissolution

Utilization of renewable materials, such as carbon dioxide and cellulose, is a prevailing goal of green chemistry. Homogenous conditions promote the use of cellulose, but finding solvent systems that appreciably dissolve this robust polymer is a difficult task. Processing cellulose with minimal waste and economic cost are additional considerations, and existing methods warrant improvement in these regards. In another fashion, the utilization of carbon dioxide is dependent upon novel methods for capture and storage (CCS). Researchers at the Dalian National Laboratory for Clean Energy, China, have integrated the goals of CCS and cellulose dissolution in their latest research effort.

It is well known that mixtures of organic liquids, comprised of a strong base and an alcohol, form reversible ionic compounds upon the introduction of carbon dioxide. By using 1,1,3,3-tetramethyl guanidine in combination with dimethylsulfoxide (DMSO) and ethylene glycol, in particular, they observed microcrystalline cellulose dissolution of up to 10 wt% under mild conditions. The presence of the co-solvent DMSO was integral to achieve this extent of dissolution, and cellulose regeneration and recovery could be accomplished by several methods.

Jenna Flogeras obtained her B.Sc. and M.Sc. in Chemistry from the University of New Brunswick (Fredericton), Canada. She is currently working towards her Ph.D. at Memorial University of Newfoundland, under the supervision of Dr. Francesca Kerton. Her research is focused on the synthesis of biodegradable polymers using main-group metal complexes as catalysts.

Vanillin derived polymers

Vanillin building blocks polymersResearch by French scientists has identified 18 vanillin derived chemicals for application in the synthesis of bio-based polymers. Vanillin is interesting as a chemical intermediate because of its different functional groups, and because it is manufactured in different ways. Extraction of natural vanillin and fermentation of bio-based ferulic acid are high cost options compared to the petroleum derived synthesis from guaiacol. An alternative route to vanillin has recently been proposed starting from p-cresol, but this approach is also based on non-renewable feedstocks. Another procedure that presently has a minority share of global vanillin production is the valorisation of lignin. This process had fallen out of favour somewhat, but cleaner technologies have revitalised research into vanillin derived from Kraft lignin, benefiting from the growing interest in producing chemicals from lignin more generally.

Polymers of vanillin are known, but are not often significantly diversified from the parent molecule. This latest work lead by Sylvain Caillol has resulted in the synthesis of difunctionalised epoxides, carbonates, alkenes, alcohols, amines and carboxylic acids, all with obvious potential as monomers for bio-based polymers. Different polymer types have been targeted, including epoxy resins, polyesters and polyurethanes. Through this research a number of opportunities for new and interesting renewable polymers have been opened up, which utilise the abundant resource of lignin via the important chemical intermediate vanillin.

Shrimp shells to mine uranium from the ocean

Shrimp shells that would otherwise be thrown away by the seafood industry have been turned into tough fibres that can harvest valuable metals from water.

Robin Rogers, and his team at the University of Alabama in the US, had long been interested in using ionic liquids to process cellulose but the Deepwater Horizon oil spill in 2010 encouraged them to try something similar with chitin, the structural biopolymer that makes up the shells of various crustaceans. ‘We started working with the Gulf Coast Agricultural and Seafood Co-Op in Bayou La Batre, looking at uses for their shrimp shell waste, about the same time as the moratoriums on shrimping. It was quite clear that new products and profits were needed.’
