Natural solvent can recycle waste plastic foam

      Using purified from citrus peel essential oils limonene to recycle waste polystyrene, but also discuss about limonene extracting from the Nepeta ear. Limonene dissolved polystyrene for various conditions were studied and investigated various methods limonene recycling polystyrene use.

 

  Comprehensive utilization of citrus peel performed by extracting the active ingredient of orange peel, has been the essential oils, carotenoid pigments, orange peel glycosides, pectin and cellulose powder five main ingredient. This five substances extraction process conditions were studied for five continuous extraction process routes substance has been designed, the extracted substance was isolated, purified and identified. Study on the conditions and solution viscosity polystyrene limonene dissolved with temperature and concentration changes.

   However, it is difficult to achieve large-scale recycling. Actually, we are still using polystyrene recycling machines for polystyrene recycling.
