Wells Plastics Ltd - Reverte

ReverteTM is a family of oxo-biodegradable additive masterbatches which has been developed for a wide range of polymers and packaging applications.

The term ‘Oxo-biodegradability’ is a hybridisation of two words; oxidation and biodegradability. It defines clearly a two-step process initiated in this case by the ReverteTM additive degrading (breaking up) the polymer chain in order to make it available for biodegradability within the environment when a treated item has finished its useful life.

The oxidation phase reduces the polymer molecular weight and introduces oxygen into the structure. This process transforms the plastic from long strands to much smaller lengths. By reducing the chain length of the polymer the material loses its physical strength, making it brittle and non-plastic. The biodegradability aspect refers to the conversion of these lower molecular weight species by bacteria into biomass, CO2 and H2O.
