In an effort to supplant the petroleum-based polymers and reduce waste-related environmental problems, biopolymers are the best candidate due to their renewability, biodegradability and commercial viability. Polylactic acid (PLA) is among the commodity biopolymers that are comparable in terms of properties and performances to polyolefin. Life cycle assessment of PLA reported that it is possible to reduce green house gas emission, yet it is subjected to the raw materials of PLA, process and source of energy used [1].
