Plastic from Poly-lactic acid is more useful bio-based polymer because it possesses the following properties: bio compatibility, biodegradability, good mechanical properties and non toxicity.
The global poly-lactic acid market was estimated to be 360.8 kilo tons in 2013, which is expected to reach 1,205.3 kilo tons by 2020. (Grand View Research, 2015).
The raw materials used to produce poly lactic acid are abundant and cheap thus readily available. In Tanzania research is done to produce lactic acid (monomer and raw material for the poymer) from sisal ball.
PLA plastic can degraded by a number of enzymes found in the natural environment.
