According to Wells Plastics, which developed Reverte under contract to PGBC, here’s how the oxo-biodegradable process works:

  • The Reverte masterbatch is blended into the PET resins used to make the preforms for the bottles;
  • Once disposed of and exposed to UV light, heat and moisture, the discarded bottle commences its degradation profile, first embrittling and then breaking into small pieces;
  • Once the molecular weight is sufficiently reduced, the material becomes ready for bio-digestion, whereby the broken down matter becomes a food source for bacteria or microbial activity.
  • In general terms, the anticipated time to totally degrade the plastic bottle is estimated to be about five to 10 years, depending on environmental conditions in which the bottle has been placed.
