ABSTRACT
In comparison to the other biopolymers, PLA has excellent characteristics since it’s biodegradable, nontoxic, compatible, sustainable, and renewable. The effluent treatment with a higher nutrient content presents a significant potential for the development of environmentally friendly, effective, and long-lasting PLA membranes. Membranes of PLA should acquire complexity, control porosity, and dimensional stability for enhanced the absorptive properties which favorably obtain by additively manufactured membranes. This review discusses the current requirement of biopolymer in wastewater treatment specifically PLA & it’s composite based membranes using 3D printing technology. Furthermore, adsorption capacity (90–98%) and various isotherm and kinetic models are explained in detail.
