Application

Design takeaway

Focus on designing for disassembly and incorporating recycled materials to leverage the environmental and employment benefits of increased circularity.

How to apply

When selecting materials for a new product, evaluate their recyclability and the potential for using recycled content, considering the broader environmental and socio-economic implications within the target market's supply chain.

Project actions

  • 01When choosing materials for your design, think about how easy they are to recycle and if recycled versions are available.
  • 02Consider the entire journey of your product's materials, from creation to disposal or reuse.

Method & Evidence

AimTo compare the environmental and socio-economic impacts of current PET and polyolefin plastic supply chains in Michigan with a future scenario aiming for a 45% recycling rate.
MethodMaterial flow analysis combined with environmental and socio-economic metrics.
ProcedureResearchers modeled existing plastic supply chains and a future 'NextCycle' scenario for PET and polyolefins in Michigan. They then analyzed material flows alongside greenhouse gas emissions, energy consumption, employment, wages, and revenue generation for both scenarios.
ContextRegional plastic supply chains (Michigan, USA)

Strengths & Limitations

Strengths

  • +Comprehensive analysis of both environmental and socio-economic factors.
  • +Scenario-based approach allows for future projection and planning.

Limitations

The study is specific to Michigan and certain plastics; broader economic impacts might vary by region and material type.

Reliability & validity

The study uses established methods like material flow analysis and integrates multiple metrics, enhancing its reliability. Validity is supported by its focus on a specific, well-defined regional system.

Think critically

How might the 'loss of revenue generation outside of Michigan' impact the overall feasibility and adoption of such 'NextCycle' scenarios in other regions or at a national level?

Design Principles

"Maximize resource circularity by designing products and systems that facilitate high rates of material recovery and reuse, balancing local economic gains with potential shifts in revenue streams."

This research highlights the tangible benefits of enhancing circularity within material supply chains. For designers and engineers, it underscores the importance of considering the entire lifecycle of materials, not just their initial production and use, to achieve broader sustainability goals.

06

What This Means for Your Design

Making more plastic recyclable and actually recycling it can help the environment a lot and create jobs, even if it means less money from selling new plastic.

How to use in your project

  • 1.Use the findings to justify material choices in your design, linking them to reduced environmental impact and potential economic benefits.
  • 2.Refer to the methodology to inform your own research into material lifecycle assessments.
