Degradable Plastic- a plastic designed to undergo a significant change in its chemical structure under specific environmental condition, resulting in loss of some properties that may be measured by standard test methods appropriate to the plastic and the application in a period of time that determines its classification



  • DIN FNK 103.2 (1993)-A plastic material is called biodegradable if all its organic compounds undergo a complete biodegradation process.  Environmental conditions and rates of biodegradation are to be determined by standardized test methods.
  • CEN (1993)-A degradable material in which the degradation results from the action of microorganisms and ultimately material is converted to water, carbon dioxide and/or methane and a new cell biomass.
  • BPS Japan (1994)-Biodegradable plastics are polymeric material which are changed into lower molecular weight compounds where at least one step in the degradation process is through metabolism in the presence of naturally occurring organism.
  • ISO 472:1988-Biodegradable plastics are plastic designed to undergo a significant change in its chemical structure under specific environmental conditions resulting in a loss of some properties that may vary as measured by standard test methods appropriate to the plastics and application in a period of time that determines its classification.  The change in chemical structure results from the action of naturally occurring microorganisms.
