Life Cycle Assessment (LCA) reveals that a plastic cup with a paper-based K3 decoration exhibits the lowest overall environmental impact compared to glass, pure plastic, and composite packaging for yoghurt. This sustainability research insight is drawn from a 2020 study published in Entecho. Using Life cycle assessment (lca), researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing packaging, opt for materials and combinations that demonstrably reduce environmental impact across key metrics like climate change and ecotoxicity, such as plastic with paper elements.
Plastic-paper composite yoghurt cups offer superior environmental performance over glass and pure plastic alternatives.

Key Findings
- 01Plastic packaging with K3 decoration (paper) demonstrated the best overall environmental performance.
- 02Glass and composite packaging generally showed higher environmental impacts than plastic, with notable exceptions in fossil fuel consumption and human toxicity.
- 03Composite and glass packaging had the highest impact in the Climate Change category.
- 04Freshwater ecotoxicity was most significantly impacted by glass and composite packaging.
- 05The primary environmental burdens for plastic cups stem from PP granulate production, for glass from glass manufacturing, and for composite from composite material production.
Application
Design takeaway
When designing packaging, opt for materials and combinations that demonstrably reduce environmental impact across key metrics like climate change and ecotoxicity, such as plastic with paper elements.
How to apply
When selecting materials for food packaging, conduct or consult LCA data to compare options like plastic-paper composites against traditional materials.
Project actions
- 01When researching materials for your design project, look for Life Cycle Assessment (LCA) data.
- 02Consider how different parts of a product's lifecycle (manufacturing, use, disposal) contribute to its environmental impact.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a robust methodology (LCA) for comprehensive environmental evaluation.
- +Compares a range of common packaging materials.
Limitations
It can be challenging to find comprehensive LCA data for all materials, and the scope of the assessment (e.g., end-of-life treatment) can significantly affect results.
Reliability & validity
The reliability of LCA studies depends heavily on the quality and completeness of the data used. Validity is enhanced by adhering to established LCA standards (e.g., ISO 14040 series).
Think critically
How might the 'best' material choice change if the end-of-life scenario (e.g., recycling rates, waste management infrastructure) is significantly different in various regions?
Design Principles
"Select packaging materials and constructions that minimize lifecycle environmental burdens, considering factors beyond just material composition."
Understanding the full environmental footprint of packaging materials is crucial for making informed design decisions. This research provides data-driven insights into the trade-offs associated with different material choices, enabling designers to prioritize sustainability in product development.
What This Means for Your Design
A plastic yoghurt pot with a paper label is better for the environment than a glass or fully composite one, mainly because of how the materials are made.
How to use in your project
- 1.Use findings from LCA studies to justify material choices in your design project, explaining the environmental benefits.
