| Type of Material | Regular polyethylene (PE) | 100% biodegradable polypropylene with TDPA additives | Starch-based biodegradable material |
| Type of degradation | Non-degradable | Oxo-biodegradable | Decomposable & 100% biodegradable |
| Details of degradation | Not degradable | The specified environment conditions (heat or light), after a certain period of time led to a significant material change in the chemical structure of the loss of certain properties (e.g. integrity, molecular weight, structure, mechanical properties), long molecules break into small molecules, and these small elements will be biodegradable. | Under the natural environment such as soil, sand for compost, the material is decomposed into CO2, H2O and biomass by microorganism, e.g. bacterial, fungi and algae. |
| Time of degradation | It does not degrade in 100 years | The plastic degrades into fragments within 12 to 36 months with the effect of oxygen, light, heat and pressure. Then the fragments are converted into CO2 and H2O by the microorganisms. | Biodegradation of more than 90% in 180 days. |
