4. Polylactic acid (PLA) yiri petrochemical synthetic plastics na isi anụ ahụ Njirimara na ike ọtụtụ-eji na-emepụta dị iche iche ngwa ngwaahịa.Poly (lactic acid) (PLA) nwekwara ezigbo ọkụ na nghọta, nke ya na ihe nkiri nke polystyrene mere na enweghị ike ịnye ya site na ngwaahịa ndị ọzọ na-emebi emebi.
5. Polylactic acid (PLA) nwere ike kachasị mma na ductility, a pụkwara ịmepụta ya site na usoro nhazi dị iche iche.Enwere ike ịme poly lactic acid (PLA) ka ọ bụrụ ngwaahịa dị iche iche dabere na mkpa nke ụlọ ọrụ dị iche iche.
6.
