Abstract: As a core pollution link in automobile manufacturing where hazardous waste generation accounts for over 90% of the total across the four major processes, the green transformation of the painting process holds strategic significance for achieving the goals of a "zero-waste city". Based on the theoretical framework of a "zero-waste factory", this study systematically analyzes the hazardous waste generation mechanisms in key stages such as pre-treatment, sealing, and spraying. By adopting a collaborative treatment strategy of "source reduction, process control, and end-of-pipe treatment", and implementing measures such as waterborne or solvent-based waste solvent treatment, mask-free sealing, robot-based efficient cleaning, and resource recovery, a 50% reduction in hazardous waste has been achieved, along with a decrease in overall operational costs. This provides a replicable technical pathway and management approach for the green transformation of the automotive industry.
