Flue gas reclaimed as polymer feedstock

Jennifer Newton writes about a Green Chemistry article in Chemistry World

The first systematic environmental assessment of an industrial plant that produces polyols from carbon dioxide has revealed that they significantly reduce both carbon dioxide emissions and the demand on fossil fuel reserves.

Polyols are the major component of polyurethanes, which make up foams or thermoplastic urethanes in a wide range of applications from mattresses to ski boots. Most polymers are made from fossil fuel-based feedstocks.

10th International Conference on Renewable Resources & Biorefineries

The 10th International Conference on Renewable Resources and Biorefineries is taking place on June 4-6, 2014 in Valladoid, Spain. A range of delegates from university, industry, governmental and non-governmental organizations and venture capital providers will present their views on industrial biotechnology, sustainable (green) chemistry and agricultural policy related to the use of renewable raw materials for non-food applications and energy supply.

The conference further aims to provide an overview of the scientific, technical, economic, environmental and social issues of renewable resources and biorefineries to give an impetus to the biobased economy and to present new developments in this area. The conference will provide a forum for leading political, corporate, academic and financial people to discuss recent developments and set up collaborations.

The three day international conference will consist of plenary lectures and oral presentations by international experts, a poster session and an exhibition. Companies and research organizations are also offered the opportunity to organize a satellite symposium. Around 400 international participants are expected from over 30 countries.

A great line-up of speakers has been confirmed, with the following as just a small selection:

  • Prof. Richard Wool, University of Delaware, USA
  • Prof. Karen Wilson, European Bioenergy Research Institute
  • Prof. Eric Beckmann, University of Pittsburgh, USA
  • Prof. Yusuf Christi, Massey University, New Zealand

There’s still time to sign up with pre-registration closing on June 1, 2014.

Freeze-dried cells make better biocatalysts

Jenifer Mizen writes about a Green Chemistry article in Chemistry World

A biocatalytic cascade using mashed-up cells has overcome extraction and solubility problems associated with using enzymes in chemical syntheses.

Enzymes are excellent catalysts for making chiral molecules. One-pot reactions under mild conditions are often possible with more than one catalyst, allowing multi-step syntheses in one go. But if enzymes are used as catalysts, they have to be extracted and purified, and expensive co-factors often need to be added. There are also solubility issues: enzymes are usually most active in buffers, but many of their substrates are hydrophobic, limiting the productivity of the biotransformation because the substrate won’t dissolve in aqueous buffers.

It is thought that the cell envelope helps to stabilise the enzymes in organic solvent

Seeing the fuel for the trees

James Sherwood is a guest web-writer for Green Chemistry. James is a research associate in the Green Chemistry Centre of Excellence at the University of York. His interests range from the certification and application of bio-based products, to the understanding of solvent effects in organic synthesis.

The European Commission has established a target for EU member states to obtain 20% of their energy from renewable sources by the year 2020. Although production of electricity from solar energy and hydropower are crucial technologies in achieving this goal, liquid hydrocarbon fuels are seemingly irreplaceable in certain heavy transportation sectors (specifically sea freight and aviation).

Direct thermocatalytic transformation of pine wood into low oxygenated biofuel

Scientific advances are now being made in the use of non-food crops to produce liquid hydrocarbon fuels, complementing the established oxygenated biofuels made of ethanol and bio-diesel. The latest research demonstrates that pine wood can be successfully converted into a mixture of liquid hydrocarbons. The resulting fuel has a similar calorific value to diesel, and contains less than 5% oxygen.

The necessary catalyst is made through a simple wet impregnation technique to give copper and ruthenium supported on phosphotungstic acid, which is then calcined. The transformation of the lignocellulosic biomass is conducted under hydrogen at an elevated temperature to produce the liquid fuel (30 wt%), which separates from an aqueous phase and any residual solid. The organic liquid was found to contain a number of mostly cyclic aliphatic hydrocarbons and also aromatic compounds, and thus is an attractive option as a next generation biofuel.

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
