February 3, 2022 /3BL Media/ - Over the course of 2021, the Healthcare Plastics Recycling Council (HPRC) embarked on a second phase of advanced recycling work and partnered with advanced recyclers to conduct a pilot project to better understand the suitability of a mixed stream of healthcare plastics as a feedstock for different advanced recycling technologies. The goal of this work was to uncover new recycling opportunities that will reduce landfill waste, carbon emissions associated with creating virgin plastic, and reliance on fossil fuels — ultimately enabling greater material circularity. This pilot project builds upon HPRC’s earlier research and interviews with advanced recycling companies across the U.S. to understand the different types and maturity levels of advanced recycling technologies, including purification, decomposition, and conversion.

“This pilot project was critical to our understanding of how advanced recycling technologies can address the healthcare plastics waste stream in a meaningful way,” says Andrew Green, Market Development Manager, Rigid Medical Packaging at Eastman Chemical Company, member of HPRC. “Its findings represent a significant step forward in understanding opportunities and challenges associated with recycling plastic materials commonly found in real-world healthcare settings. Based on this research, we’ve concluded that healthcare plastics are a viable and valuable feedstock for a variety of advanced recycling technologies, given their ability to handle material streams that are incompatible or difficult to handle with mechanical recycling.”

Summary of Key Takeaways by Stakeholder Group

Hospitals  

  • Plastics provide unique benefits and are essential for delivering cost-effective, successful outcomes in healthcare settings; a robust recycling strategy is critical to helping reduce the environmental impacts of healthcare plastics. 
  • Ninety percent of the healthcare plastics evaluated in this study can be processed using one or more advanced recycling technologies.  
  • Possible barriers to advanced recycling in healthcare settings are expected to be similar to those found with mechanical recycling and include space limitations for collection, competing staff priorities, and education required to enable effective collection of materials.  

Medical Product Manufacturers 

  • Plastic healthcare packaging plays an essential role in delivering a safe, sterile, and effective product to the customer in a cost-effective manner.  
  • “Designing for recyclability” includes avoiding the use of materials that negatively impact yields of advanced recycling processes. For example, nylon and paper reduce the yield of output for the advanced recycling processes examined in this white paper, which increases recycling costs and makes circularity more expensive.  
  • Use of PVC, which provides uniquely beneficial functionality in healthcare settings, should be limited when possible, as it contaminates materials outputs and most advanced recycling technologies can only tolerate it at low levels in mixed waste streams due to its corrosive properties.  

Advanced Recyclers 

  • A typical mixed stream of healthcare plastic packaging materials is an acceptable feedstock for many advanced recycling technologies.
  • Advanced recyclers can help promote and drive viability of processing real-world mixed plastic waste streams from hospitals by focusing on the impact of various materials on yield, communicating about acceptable levels of difficult-to-recycle materials in a mixed stream, and providing guidance for medical manufacturing and healthcare industries. 
  • Innovations that expand the range of acceptable feedstocks for advanced recycling should aim to increase yields and circularity while maintaining safety and performance imperatives. 
  • Advanced recycling processes should seek to maximize material circularity in order to reduce landfill waste, reduce carbon emissions associated with creating virgin plastic, and reduce reliance on fossil fuels.

Next Steps

During 2022, HPRC will build upon the previous two phases of advanced recycling work to design and conduct another pilot study – this time collecting a mixed stream of flexible healthcare plastics from select hospitals and processing them using different advanced recycling technologies. By processing commercial scale samples that are collected “in real life” at hospitals, HPRC seeks to understand how a typical mix of healthcare packaging materials is processed and gather insights on which materials are more or less favorable for different recycling technologies.
