Right Size + Right Chemistry = Right Stuff for Plastics Manufacturing

Plastic manufacturing is an energy-intensive process. Now, research performed in part at the National Institute of Standards and Technology (NIST) has revealed a way to reduce the energy demand in one key step of plastic manufacturing by using a class of materials that can filter impurities more efficiently than the conventional manufacturing process.

The findings, published in the journal Science, show that materials called metal-organic frameworks (MOFs) can effectively remove the contaminant acetylene from ethylene, the material from which much of the world’s plastic is made. The research suggests that filtering out acetylene using MOFs would produce ethylene at the high purity that industry demands while sidestepping the current need to convert acetylene to ethylene via a costly catalytic process.
