Key Findings

  • 01The raw material supply period accounts for over 90.2% of the total environmental impacts in the lifecycle of polythene milk packaging.
  • 02Plastic packaging contributes most significantly to Fossil fuels, Respiratory inorganics, and Climate change.
  • 03Landfill treatment of plastic packaging waste adds the highest environmental impact (16.1%), followed by incineration (5.3%), while recycling reduces impacts by 75.9%.

Application

Design takeaway

Prioritize the selection of materials with lower raw material extraction impacts and design for effective end-of-life management, with a strong emphasis on recyclability.

How to apply

When designing new packaging, conduct an LCA to identify the primary environmental hotspots and focus design efforts on mitigating these areas, such as exploring alternative bio-based or recycled materials and designing for disassembly and recycling.

Project actions

  • 01When researching materials for your design project, look for data on their full lifecycle environmental impacts, not just their end-of-life properties.
  • 02Consider how your design choices at the beginning of the product lifecycle can have the biggest impact on sustainability.
03

Method & Evidence

AimTo quantify the environmental impacts of polythene milk packaging throughout its lifecycle and compare the effects of different waste treatment methods.
MethodLife Cycle Assessment (LCA)
ProcedureAn LCA was conducted using the Eco-Indicator 99 method, gathering data on mass, energy fluxes, and environmental emissions from literature and site investigations. Three waste treatment scenarios (landfill, incineration, recycling) were compared.
ContextPackaging design and waste management

Variables

IV["Material type (polythene)","Waste treatment method (landfill, incineration, recycling)"]
DV["Total environmental impacts (e.g., Eco-Indicator 99 score)","Contribution to specific impact categories (Fossil fuels, Respiratory inorganics, Climate change, etc.)","Percentage change in environmental impact due to waste treatment"]
CV["Product type (milk packaging)","Lifecycle stages considered (raw material supply, manufacturing, use, waste treatment)"]

Strengths & Limitations

Strengths

  • +Provides a comprehensive lifecycle perspective, not just end-of-life.
  • +Compares multiple waste treatment options, offering practical insights.

Limitations

It can be challenging to find comprehensive lifecycle data for all materials, and simplified LCA tools may not capture all nuances.

Reliability & validity

The reliability of the LCA depends heavily on the accuracy and completeness of the input data. The validity is strengthened by using a recognized methodology like Eco-Indicator 99, but may be limited by the specific impact categories it covers.

Think critically

Given that raw material extraction is the primary environmental burden, what innovative material sourcing or processing technologies could be developed to further reduce this impact for packaging?

05

Design Principles

"Minimize the environmental impact of a product by addressing the most significant lifecycle stages, particularly raw material sourcing and end-of-life management."

This highlights that design decisions focused solely on end-of-life solutions may overlook the most substantial environmental burdens. Designers and engineers should prioritize material selection and sourcing strategies to mitigate the primary environmental hotspots.

06

What This Means for Your Design

Making milk cartons out of plastic is bad for the environment, mostly because of how the plastic is made in the first place. Recycling the cartons is the best way to deal with the waste.

How to use in your project

  • 1.Use this study to justify the importance of conducting a lifecycle assessment for your own design project's materials and processes.
  • 2.Reference the finding that raw material extraction is a major contributor to environmental impact when discussing your material choices.

Paragraph starter

Research indicates that the environmental impact of plastic packaging, such as polythene milk cartons, is predominantly driven by the raw material extraction phase, accounting for over 90% of total lifecycle impacts. This underscores the critical importance of material selection in sustainable design, as efforts focused solely on waste management may overlook the most significant environmental burdens. Furthermore, recycling emerges as the most effective waste treatment method, capable of reducing environmental impacts by up to 75.9%, significantly more than landfill or incineration.
