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
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
