In the bustling plastic recycling hubs of Delhi's Narela or Mumbai's Dharavi, thousands of units process tons of plastic daily. Yet, a crucial question remains: Can second or remixed PP truly be classified as recycled plastic? The answer lies at the intersection of technical standards, market realities, and regulatory frameworks.
The Classification Conundrum
"The term 'recycled' has become a marketing buzzword," observes Dr. Sunil Kumar, Head of the Plastic Technology Research Center. "But true recycling involves a structured process that meets specific technical and environmental standards."
According to Bureau of Indian Standards (BIS), recycled plastics fall into distinct categories:
Post-Consumer Recycled (PCR)Â Material collected from consumer waste streams, such as water bottles or packaging materials. These materials typically undergo extensive cleaning and processing before reuse.
Post-Industrial Recycled (PIR)Â Clean industrial scrap from manufacturing processes, often easier to recycle due to known composition and limited contamination.
Reprocessed Materials A grey area where most small-scale recyclers operate, processing mixed industrial and consumer waste.
The Reality of Second/Remixed PP
At Vishnu Plastics, a medium-sized recycling unit in Gujarat, the owner Rajesh Patel explains the practical challenges: "Everyone wants recycled material, but few understand the complexities involved. True recycling isn't just melting and remolding – it's a scientific process."
Current Market Practices vs. Standards
Most second PP in India undergoes the following process:
Collection from various sources
Basic segregation (often manual)
Grinding and washing
Melting and pelletization
Basic quality testing (if any)
However, certified recycling requires:
Source verification and documentation
Contamination analysis
Controlled processing parameters
Regular quality testing
Property certification
Traceability maintenance
The Cost Factor
A detailed cost breakdown reveals why proper recycling remains challenging:
Standard Remixing Process (per kg):
- Material procurement: ₹40-50
- Basic processing: ₹15-20
- Labor: ₹5-8
- Total: ₹60-78
Certified Recycling Process (per kg):
- Sorted material procurement: ₹50-60
- Advanced processing: ₹25-30
- Testing and certification: ₹10-15
- Documentation: ₹5-8
- Total: ₹90-113
Case Study: GreenPlast Solutions
One success story emerges from Vadodara, where GreenPlast Solutions has established a certified recycling facility. Their journey offers valuable insights:
Initial Investment:
Advanced washing line: ₹1.2 crore
Testing laboratory: ₹40 lakhs
Certification process: ₹15 lakhs
Results after 18 months:
Premium pricing: 20-25% higher than standard remixed PP
Quality consistency: 95% match with virgin material properties
Regular clientele: Major automotive and consumer goods manufacturers
The Regulatory Landscape
Recent CPCB guidelines have become stricter, requiring:
Registration of recycling units
Regular quality testing
Proper documentation of material source
Environmental compliance
"The regulations are necessary but challenging for smaller units," notes Mr. Amit Shah, President of the Plastic Recyclers Association. "We need a balanced approach that promotes quality while being practical for smaller players."
The Path Forward
For second/remixed PP to be legitimately termed as recycled:
Process Standardization
Implementation of quality management systems
Regular testing protocols
Documentation procedures
Infrastructure Development
Investment in sorting technologies
Advanced washing facilities
Quality testing equipment
Market Education
Clear communication of quality standards
Transparent pricing mechanisms
Customer awareness programs
Expert Recommendations
Dr. Meena Sharma, Polymer Scientist at IIT Delhi, suggests a three-tier approach:
Basic recycling certification for small units
Advanced certification for medium-scale processors
Premium certification for high-end applications
