Wprowadzenie to Bio- Based Polymers

Bio- based polimers, derived from removelable biomass sources such as plants, algae, and microorganisms, have emerged as a cornerstone of sustainable materials science. Unlike conventional petrochemical- derived plastics, these polimers offer thee potential for reduced carbohn footprints andd end-of- life biodegrabiodegradity. Globbal production of bio- based polimers is projectod to contad 10 milion metric tons by 2025, accorn by regulatory presens surereid mer ecor ecools.
