Why Manage Your Glycol Waste?
Mono-ethylene glycol (MEG) and propylene glycol (PG) are used in HVAC systems, industrial refrigeration, automotive engines, and food processing worldwide. Each year, industry consumes more than 30 million metric tons of glycols, creating a significant waste stream.
Traditional disposal methods like landfilling or incineration are costly and environmentally damaging. On-site glycol recycling transforms waste into reusable solvent, cutting purchase costs by up to 90% and reducing your environmental footprint simultaneously.

Modern Glycol Recycling Technology
Our systems utilize vacuum distillation technology that lowers glycol's boiling point from 197°C to a safer 85-90°C range. This gentle process removes water and light impurities while leaving behind heavy oils, rust particles, and insoluble compounds.

Quantifiable Financial & Environmental Impact
| Scenario (per 1,000L of spent glycol) | Disposal Cost (USD) | New Glycol (USD) | Total Cost (10 batches) | CO₂ Emissions (kg) |
|---|---|---|---|---|
| Traditional disposal approach | $1,200 | $2,600 | $38,000 | 6,900 |
| On-site recycling solution | $200 | $300 | $5,000 | 1,100 |
For organizations disposing of 10,000L or more annually, simple payback typically occurs within 12-18 months. In regions with strict environmental regulations, documented recycling also reduces liability exposure by 40-60%.
Insight: The average manufacturing facility spends $2,500 per 1,000L on combined disposal and new glycol procurement. Recycling cuts this to under $500 for significant recurring savings.
Colorado Brewery Saves $78,400 Annually
A craft brewery using 40,000L of 40% propylene glycol brine annually eliminated disposal fees and slashed glycol purchases:
Solvent Costs
Previous: $92,000/year
Reduction: $74,400 (81%)
Disposal Costs
Previous: $26,000/year
Reduction: $22,000 (85%)
"Our payback period was just 14 months. The system continues to deliver savings while helping us achieve our sustainability goals."

Maintenance Best Practices
Maximize your glycol recovery system's efficiency with these operational recommendations:
Pre-filter solids – 100µm bag filters prevent sludge accumulation, improving heat transfer and extending component life.
Use genuine vacuum oil – Third-party oils cause premature seal failure and reduced efficiency.
Condition the condenser quarterly – Citric-acid solution removes scale and optimizes heat transfer.
Record operational data – Tracking temperatures, times, and volumes helps identify performance trends before they become problems.
Implement predictive maintenance – Scheduled inspections and component replacement prevent unexpected downtime.
Meeting Regulatory Requirements
Environmental regulations continue to tighten globally. In 2024, the U.S. EPA included spent glycols in its universal waste proposal, while the EU's Industrial Emissions Directive requires facilities to prioritize waste minimization strategies during permit renewals.
MIT's 2023 industrial sustainability study found that facilities implementing closed-loop solvent recovery:
Reduced hazardous waste volume by 65% on average
Cut disposal-related paperwork by 40%
Lowered environmental compliance operating costs by 25-30%
Cost Reduction
$400,000+ savings annually for medium-sized industrial operations
Environmental Impact
10,000-30,000 kg CO₂ equivalent reduction per facility annually
Regulatory Compliance
Meets ISO 14001 & regulatory waste minimization requirements
