University of Sheffield Professors Ian Reaney, Department of Materials Science and Engineering, and Lenny Koh, Management School, undertook the first comparative life cycle analysis of piezoelectric materials as part of an EPSRC project. Their findings indicate that a replacement for lead zirconate titanate (PZN), recommended by global authorities due to its green credentials, is more dangerous to the environment.
Now is the time to look at the circular economy on the micro-level. Much as fast expanding markets require us to look at the economy at the granular level, circular economy principles require consideration of resources on a molecular level. Chemistry is the study of matter, and “green chemistry” – or what we in the business world might call molecular technology – will be a key component in closing the overall consumption loop.
It might seem surprising to find the world’s chemical companies on the front lines of preventing climate change, fighting to disrupt their own industries. But in a sweeping accord reached on Saturday in Kigali, Rwanda, companies including Honeywell and Chemours, a DuPont spinoff, were among the most active backers of a move away from a profitable chemical that has long been the foundation for the fast-growing air-conditioning and refrigeration business.
A team of chemists including Daniel Weix from the University of Rochester has developed a process for identifying new catalysts that will help synthesize drugs more efficiently and more cheaply. The trick was to do something that has not been attempted before, to examine libraries of drugs to find the cure for bad chemistry: new catalysts.
