Why Purging Compounds Are Key to Sustainable Plastics Manufacturing
In today’s plastics manufacturing environment, sustainability isn’t just a trend—it’s a business imperative. Reducing waste, improving efficiency, and cutting production costs are all top priorities for processors in the U.S., Mexico, and around the world. One of the simplest and most impactful ways to support these goals is through the consistent use of purging compounds.
Whether you're changing colors, switching materials, or preparing for shutdown, purging compounds help eliminate contamination, reduce scrap, and improve the reusability of plastic materials—three critical pillars of sustainable production.
1. Reduce Waste During Changeovers
Material and color changes are among the most wasteful phases in plastics processing. Standard resin flushes often fail to clean machines efficiently, requiring large volumes of virgin resin and extended downtime to fully purge the system.
Using a dedicated purging compound like Asaclean®:
-
Drastically reduces the amount of scrap produced during transitions
-
Cleans more thoroughly and in less time than virgin resin alone
-
Cuts down on overall resin consumption and machine wear
-
Supports lean manufacturing by improving first-shot quality after changeovers
2. Enable Reuse of Out-of-Spec Material
Even with optimized processes, some off-spec product is inevitable. The key to sustainable operations is turning that material into a valuable resource—not landfill waste.
When machines are purged effectively with a high-performance product like Asaclean®, the remaining resin in the system is cleaner and less prone to contamination. That means:
-
More out-of-spec material can be safely reprocessed as regrind
-
Manufacturers can reduce reliance on virgin resin
-
Overall material costs go down while environmental performance improves
3. Improve Recyclability and Maintain Resin Integrity
Contamination is the enemy of successful recycling. Dirty transitions between materials or colors often result in mixed resins that are unusable in future runs, defeating sustainability goals.
Purging compounds help maintain the integrity of recycled resin streams by:
-
Preventing cross-contamination between incompatible materials
-
Preserving the quality of regrind for internal use or resale
-
Making it easier to meet recycled content targets without sacrificing quality
By supporting a cleaner recycling process, purging compounds contribute directly to a circular plastics economy.
4. Maximize Long-Term Efficiency and Cost Savings
Purging isn’t just about waste reduction—it’s about operational efficiency. A small investment in purging compounds leads to big returns over time through:
-
Shorter downtime during changeovers
-
Fewer defective parts and reduced scrap rates
-
Lower energy costs due to faster startups and transitions
-
Reduced screw pulls and maintenance due to cleaner machines
These benefits compound over time, improving productivity while supporting ESG and sustainability commitments.
