New EPA Trichloroethylene Ban Forces Immediate Industrial Solvent Sourcing Pivots
The final rule targets a core chemical used in vapor degreasing and aerosol cleaners, requiring a shift to safer alternatives.
Solvent Substitution
Process Change
Replacing hazardous chemicals with safer alternatives reduces the toxicity of industrial cleaning and manufacturing operations. Successful solvent substitution requires a new medium that matches the cleaning power or solubility of the original agent without the associated health risks. Engineers evaluate the boiling point and evaporation rate of the new candidate.
Adopting these alternatives often helps a facility meet stricter air quality standards.
Technical Evaluation
Performance testing ensures that the new chemistry does not damage the parts or leave residue that interferes with later steps like painting or welding. Compatibility with existing seals and gaskets must be verified to prevent leaks in the distribution system. Changes in dry times or application methods may require updates to the production schedule.
Cost comparisons include the purchase price and disposal fees for the spent fluid.
Regulatory Driver
Bans on specific volatile organic compounds or chlorinated fluids force manufacturers to seek different ways to degrease or dissolve materials. Occupational exposure limits often become so tight that the ventilation costs for an old chemical exceed the cost of switching to a bio-based or aqueous alternative. Insurance premiums often drop.
Transitioning to a new system involves a period of employee training to manage the different handling requirements and safety protocols. Waste streams are often easier to manage when the primary carrier is less reactive or biodegradable. Process safety improves.
