Abstract--Bisphenol A (BPA), commonly found in plastics and tars, can leach into food and beverages, raising serious health concerns such as cardiovascular disease, diabetes, developmental issues, and metabolic disorders. This study explores the potential of bio-based lacquers made from tomato processing waste—specifically tomato pomace—as sustainable alternatives to BPA-containing metal food packaging coatings. The process involves sundrying tomato waste (seeds, pulp, and skins), converting it to powder via microwave, and breaking down the cell walls using sodium hydroxide (NaOH) to extract lipids. These lipids undergo polymerization, which is analyzed using infrared spectroscopy to determine esterification levels. Ethanol is then added to form a waxy substance. The coatings on aluminum substrates showed superior mechanical properties and water resistance compared to TFS and ETP finishes. Additionally, Support Vector Machines (SVMs), a machine learning algorithm, were used to classify pH levels, proving effective in categorizing soil as acidic, neutral, or alkaline based on pH and environmental factors.
