Implementation of Syzygium cumini Garden Waste Biochar as a Sustainable Source for the Synthesis of Paints and Pigments

With increasing concerns about environmental degradation and the need for sustainable alternatives, the repurposing of organic waste materials, such as garden waste biochar, is considered a feasible opportunity to mitigate waste accumulation by creating value-added products. The present research study aims to identify the potential and investigate the feasibility of utilizing Syzygium cumini garden waste biochar as a sustainable source for pigment and paint formation. Biochar was produced from garden waste via carbonization, highlighting its chemical composition and physical properties that are conducive to the development of pigments and paints. Furthermore, this study examined various extraction techniques to isolate pigments from biochar by assessing their color properties, stability, and compatibility with paint formulations. These findings suggest that Syzygium cumini garden waste biochar holds promise as a sustainable source for pigment and paint formation, offering environmental benefits and contributing to the circular economy. In the case of feedderived pigments, the Syzygium cumini biochar-based pigment exhibited a comparatively better color intensity. Spectrophotometric analysis indicated high color retention and stability over time, suggesting its viability for various applications in the paint and dye industries. This establishes the novelty of this work, as commercial pigments are oil-based products that generate carbon footprints. This study contributes to the growing body of knowledge on sustainable material utilization and provides insights for the development of eco-friendly paint products in the construction and coatings industries.
