Frequently Asked Questions
Use of Recycled Solvents in Printing and Packaging
⸻
1. Can printing and packaging companies use recycled solvents?
Yes. Printing and packaging companies can use recycled (recovered) solvents such as ethyl acetate (EA) and methyl ethyl ketone (MEK), provided the solvents meet required purity and quality specifications.
⸻
2. What applications are suitable for recycled ethyl acetate and MEK?
Recycled EA and MEK are commonly used in:
• Flexographic and gravure printing inks
• Adhesives and laminating applications
• Coatings
• Cleaning solvents for presses and equipment
They are especially suitable for non–food packaging applications.
⸻
3. Are recycled solvents comparable to virgin solvents in performance?
Yes. When properly distilled and quality-controlled, recycled solvents can perform almost identically to virgin-grade solvents in terms of solvency, drying time, and application performance.
⸻
4. What quality standards must recycled solvents meet?
Recycled solvents should meet strict specifications, including:
• High purity (typically ≥99.5%)
• Low moisture content
• Controlled acidity
• Absence of ink residues, resins, or heavy contaminants
Consistent quality depends on a reliable solvent recovery and distillation process.
⸻
5. Can recycled solvents be used in food packaging?
This depends on regulatory and customer requirements.
• For non–food-contact packaging, recycled solvents are widely accepted.
• For food-contact packaging, stricter regulations apply, and many manufacturers require virgin solvents or recycled solvents that meet food-contact compliance standards with full traceability.
⸻
6. Are recycled solvents compliant with regulations?
Yes, as long as they comply with applicable regulations and are supported by proper documentation such as:
• Certificate of Analysis (COA)
• Safety Data Sheet (SDS)
• Batch traceability records
Customer or brand-owner specifications may impose additional requirements.
⸻
7. What are the benefits of using recycled solvents?
Using recycled solvents can provide:
• Lower raw material costs
• Reduced hazardous waste disposal
• Improved sustainability and ESG performance
• Support for circular economy initiatives
⸻
8. What issues can arise from poor-quality recycled solvents?
If quality is inconsistent, issues may include:
• Ink shade variation
• Slower or uneven drying
• Odor concerns
• Adhesive or lamination bond failures
These issues are typically related to inadequate solvent recovery processes rather than the use of recycled solvents itself.
⸻
9. What is the key factor for successfully using recycled solvents?
The most critical factor is supplier reliability, including consistent quality, proper testing, and complete regulatory documentation.
