10 Jan 2023 --- Scientists from the University of California, Riverside (UCR) have discovered a way to convert plastics into soil additives to improve soil water retention and the aeration of farmlands. The report, “Synergistic and Antagonistic Effects of the Co-Pyrolysis of Plastics and Corn Stover to Produce Char and Activated Carbon,” was published in the journal ACS Omega. UCR’s Marlan and Rosemary Bourns College of Engineering studied plastics that would otherwise be recycled or end up in landfills by breaking them down into charcoal.
