Case : Automotive Bumper Paint Solvent Recycling
Client Background
Our client is a large automotive and motorcycle parts manufacturer located in Chongqing, specializing in the painting and coating of bumpers, interior and exterior trim, and motorcycle components. Their painting process heavily relies on solvents such as thinners, nitrocellulose thinners, and cleaning agents used for spray guns and production line cleaning. With increasingly stringent regulatory requirements and rising costs, the client faced the following key challenges:
High Hazardous Waste Disposal Costs: Contaminated solvents are classified as flammable hazardous waste, leading to escalating disposal costs and complex compliance processes.
Soaring Procurement Costs: Monthly purchases of new solvents account for over 15% of the paint shop's operating costs.
Safety and Environmental Risks: Improper storage of waste solvents poses fire hazards and regulatory violations.
Decreased Cleaning Efficiency: Reusing contaminated solvents leads to spray gun clogging, increased defect rates, and increased rework.
Solution
The client installed our explosion-proof solvent recovery machine to distill and recover waste cleaning solvents, achieving a closed-loop recycling system and addressing cost, environmental, and safety issues at their source. Workflow:
Waste Collection: Contaminated solvents from the spray painting line cleaning process are collected in the feed tank of the recovery machine.
Distillation and Purification: The system heats the waste solvent in a fully enclosed, explosion-proof environment. The solvent vaporizes, condenses, and is recovered, while paint residues are solidified and separated in the chamber.
Reuse and Disposal: The purified solvent is returned to the cleaning process for reuse. The separated paint residues are disposed of as general industrial waste.
Significant Cost Reduction: Total costs for solvent procurement and waste disposal are reduced by more than 70%, achieving a full return on investment within 6 months.
Stable Coating Quality: The recovered solvent maintains stable purity, with performance comparable to new solvents, and reduces spray gun clogging issues.
Compliance and Safety: The fully enclosed distillation system complies with national explosion-proof and environmental protection standards, eliminating non-compliance risks and fire hazards.
Multi-Scenario Adaptability: This solution supports solvent recovery for various spray painting processes, including automotive bumpers, motorcycle parts, and metal/plastic components.
Customer Testimonials
“Waste solvent disposal used to be our biggest challenge – costly and risky. With JBETT's solvent recovery machines, we can convert waste solvents into usable clean solvents. Our new solvent orders have dropped significantly, and we no longer need to frequently handle hazardous waste collection. This is revolutionary for paint shops like ours.”
