Dr. Mahesh Ganesan, Assistant Professor in the Department of Chemical Engineering, leads a project focusing on repurposing polymeric waste into eco-friendly structural-colored pigments for paints. The initiative aims to address both the ecological issues of polymeric waste and toxic paint pigments.


The project aims to repurpose polymeric waste, particularly expanded polystyrene, into functional microparticles. These recycled particles will be structured into ordered micro-arrays using evaporation-driven assembly, generating structural-colored pigments without chemical additives. The primary objective is to create sustainable alternatives to conventional, ecologically harmful paint pigments. At a Technological Readiness Level (TRL) 3, the project has demonstrated experimental proof of concept. The proposed work involves optimizing the particle recovery process, assembling micro-arrays, and recovering micro-flakes for paint applications, contributing to UN SDG #12 on Responsible Consumption and Production.
