question:question 1: what is PLA?★PLA is the common name for polylactic Acid or Polyactide.★PLA is made from starch rich plants such as corn, wheat and sugar beets.★These plants are first milled to separate the starch, from which is unrefined dextrose is processed.★The unrefined dextrose goes through a fermentation process and the result is lactic acid.★After condensation, two lactic acide molecules are converted into one lactide.★The lactide molecule is then purified through vacuum distillation and a solvent-free melt causes the ring shaped molecule to turn into long chain polymers.question 2: What is the difference between biodegradable and compostable?★Biodegradable means that the products break down through a naturally occurring microorganism, such as fungi or bacteria over a period of time.★Biodegradable products are usually made from plant or animal sources.★Biodegradable products can create methane, a greenhouse gas with 62 times the global Warming potential of carbon dioxide when dumped into landfills.★Biodegradable waste may contain toxins.★Compostable plastics mean that the products must be able to break down into carbon dioxide, water, and biomass at the same rate as paper.★Also, the broken down product should not produce any toxic material and should be able to support plant life. ★Compostable products are usually made from plant materials.★Because biodegradable is used loosely with no legal enforced definition, compostability is more desirable for disposable products.
