Foam plastic recycling new method

The Institute of Chemistry of the National Autonomous University of Mexico studied a new method of solving "white pollution" that uses an aqueous solvent to restore waste polystyrene foam to the original pellet state.
According to reports, the collected Styrofoam is dissolved in a reusable commercial solvent, and the resulting mixed solution is added dropwise to the water, and the Styrofoam dissolved therein will be polymerized again. Raw balls that are clean and easy to separate, these balls can be remade into foamed plastic products.
At present, the world mainly uses “melt granulation method” to recover foam plastics, that is, it is melted and pressed into filaments after high temperature, and then cut into recycled plastic balls, but the performance of the recycled balls is obviously better than that of the new balls. The difference in beads is that the beads obtained by this new method called "precipitation precipitation method" are identical in performance to the nascent beads after the foaming treatment, and can be immediately used in the production of a stamper.
There are other important aspects of recycling foam, but the key is to reduce the waste foam to the original ball state before molding. At present, the study has entered the final stage of the extraction experiment. Next, the institute will establish a small experimental plant to verify the practicality of the recovery method and determine the production parameters for the next commercial promotion.
