Huge new projects are coming on line to produce plastics from corn through the processes of fermentation and polymerization. Now a Korean research team says it has developed a way to produce bioplastics, specifically polylactic acid, more efficiently.
Lee Sang-yup of the Korean Advanced Institute of Science and Technology says PLA can be produced through a one-step process using bioengineering. Polymers are made directly from natural feedstocks using newly developed microbial genetics that starts with E. coli. The process has the potential to reduce costs of PLA. The Korean team also says they are studying ways to build polyesters through the process.
It’s a long. long way from the lab to the factory, however
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
UL is partnering with metals additive manufacturing (AM) supplier EOS to provide AM training to EOS's customers. It's designed to promote correct usage of AM technologies by OEMs and others in manufacturing.
To commemorate Earth Day, we take a look at the state of ocean plastic. If things don't change, by 2050 the oceans will contain more plastic than fish by weight. Here are the problems, as well as some solutions.
