Biodegradable polymers are a special group of polymers that breaks down into natural byproducts such as gases (CO2, N2), water, biomass, and inorganic salts after its intended purpose by bacterial decomposition process to result. These polymers are found both naturally and made synthetically, and largely consist of ester, amide, and ether functional groups. Their properties and breakdown mechanism are determined by their chemical structure. These biodegradable polymers are often synthesized by condensation reactions, ring opening polymerization, and metal catalysts.
