Post-Consumer Recycled Plastics Offer Greater Climate Impact Reduction Than Post-Industrial

Utilizing post-consumer recycled plastics in product design can yield a more significant reduction in climate change impacts compared to post-industrial recycled plastics.

Sustainability · 2023

Key Findings

01Post-consumer recycled (PCR) plastics demonstrate a higher impact reduction potential (IRP) for climate change compared to post-industrial recycled (PIR) plastics across all analyzed scenarios.
02The proposed metrics of effective circularity (eC) and environmentally efficient circularity (eeC) provide a more comprehensive assessment of resource use over multiple product life cycles than simple reutilization percentages.
03Circularity metrics (eC) for polypropylene can range significantly, from 0.93 to 9.08 uses, depending on collection, sorting, and recycling efficiencies.

Application

Design takeaway

Prioritize the use of post-consumer recycled plastics in your designs to achieve greater environmental benefits, particularly concerning climate change mitigation.

How to apply

When selecting materials for a new design project, investigate the availability and performance of PCR options and quantify their potential environmental benefits using metrics like IRP.

Project actions

01When choosing materials for your design project, research the environmental impact of using recycled versus virgin materials.
02Consider how the source of recycled materials (post-consumer vs. post-industrial) might affect the overall sustainability of your product.

Method & Evidence

AimTo develop and apply new metrics for measuring the circularity and environmental impact reduction potential of recycled plastics, comparing post-industrial and post-consumer sources.

MethodQuantitative analysis and case study application.

ProcedureThe researchers proposed and defined two new circularity indicators: effective circularity (eC) and environmentally efficient circularity (eeC). They then analyzed the impact reduction potential (IRP) of post-industrial recycled (PIR) and post-consumer recycled (PCR) polypropylene, comparing their climate change impacts against virgin materials across various recycling scenarios.

ContextMaterial science and sustainable product development, specifically focusing on plastic recycling.

Variables

IV["Type of recycled plastic (PIR vs. PCR)","Collection, sorting, and recycling rates"]

DV["Impact Reduction Potential (IRP)","Effective Circularity (eC)","Environmentally Efficient Circularity (eeC)"]

CV["Material type (polypropylene)","Environmental impact category (climate change)"]

Strengths & Limitations

Strengths

+Introduces novel metrics for circularity assessment.
+Provides a direct comparison of PIR and PCR impact reduction potential.

Limitations

Access to specific data on recycling rates and material properties for PCR and PIR can be challenging.

Reliability & validity

The study's validity relies on the accuracy of the input data for recycling rates and life cycle assessment. Reliability would be enhanced by replicating the analysis with different plastic types and geographical contexts.

Think critically

How might the collection and sorting infrastructure for PCR materials influence their actual environmental advantage over PIR in different geographical regions?

Design Principles

"Maximize the use of post-consumer recycled content to enhance product sustainability and reduce environmental footprint."

This finding is crucial for designers and engineers aiming to enhance the sustainability of their products. By prioritizing PCR materials, design teams can make more impactful choices that contribute to a circular economy and mitigate environmental damage.

What This Means for Your Design

Recycling plastic from old products (like bottles) is better for the planet than recycling plastic from factory waste. This means designers should try to use recycled plastic from consumers whenever possible.
