Every day, tons of potentially valuable materials are discarded in various waste streams simply because recycling them is more expensive than their recoverable value. Considering that finite resources such as precious metals are among these wastes, the opportunity appears obvious.

Wendy Lee Queen, and American expat and passionate baseball player, leads the Laboratory for Functional Inorganic Materials at the EPFL in Lausanne, and has a potential solution. She is one of the leading experts of metal organic frameworks (MOF) and a pioneer of novel composite materials where MOFs and polymers in bead form provide an innovative way to fine tune affinity and selectivity for various chemical species of interest. These can be used to efficiently capture pollutants such as carbon dioxide, but also to recover valuable resources from water waste streams, such as precious metals.

Wendy’s research is a beautiful story of chemical innovation, where ground-breaking chemistry makes new things possible. And when these new things have the potential to change the way we look at our urban and industrial wastes, this is a moment chemistry is brought to life.

Sustainability as an entrepreneurial choice

Sustainability is a trendy word that is often abused, especially when speaking about chemistry. Most commodity chemicals and their highly integrated value chains remain rooted in the oil feedstock. Until this changes, it will be difficult to move towards truly sustainable technologies. The use of renewable resources to produce valuable chemicals has promised a lot but delivered little so far. Dr. Kevin Barnett aims to change that, and his approach is radical and pragmatic at the same time. No real innovation is possible without commercial attractiveness. The obvious start is something that can be useful and commercially attractive right now. Something that can’t be easily obtained from the established value chain. That something is 1,5-pentanediol, a small but wondrous molecule.

After graduate school, Kevin took the entrepreneurial way and co-founded Pyran, a company focused on the production of useful commodity chemicals from renewable resources and already launched his first commercial product; 1,5-pentanediol of course! In this fascinating discussion, Paolo and Kevin discuss career choices, entrepreneurship as a credible option for chemistry graduates, the present and future of renewable resources, and the promise for a different chemistry of tomorrow.

Bioorthogonal chemistry, tuberculosis, and making the best of opportunities

Sometimes you feel like you missed an opportunity, or didn’t make the best out of it, or sometimes you feel like life is unfair and doesn’t offer any attractive chance. Then you hear stories like Mireille Kamariza’s and your perspective changes.

This is classic Bringing Chemistry to Life episode, where an incredible personal story is intertwined with great science. Dr. Mireille Kamariza, junior fellow at the Society of Fellows at Harvard University, is driven by her personal experience growing up in war-torn Burundi. She was given the opportunity to move to and study in the U.S., rose to the challenge becoming an expert in biorthogonal chemistry and developed a technology for a highly reliable, yet simple and affordable, detection method for tuberculosis. Now Mireille, nominated as one of Fortune Magazine’s most powerful women, wants to give back and aims at addressing the TB global health crisis thanks to her technology.

While listening to Mireille’s personal story alone is well worth your time, make no mistake, there is great chemistry here. Another brilliant example of chemistry at the interface with biology, where some of the most exciting results in modern science come from.
