PET containers reduce environmental impact by 35.1% compared to glass for pharmaceutical packaging

Why It Matters

This research demonstrates a quantifiable method for achieving environmental impact reduction in product design. By integrating Life Cycle Assessment (LCA) into the eco-design process, designers can identify critical areas for improvement and validate the effectiveness of their design choices, leading to more sustainable product development.

Key Finding

By following a structured eco-design approach and using Life Cycle Assessment to measure environmental impact, switching from glass to PET packaging for cough syrup significantly reduced the product's environmental footprint by over a third.

Key Findings

• The application of standardized eco-design and LCA methodologies led to a reduction in environmental impact.
• Substituting a glass container with a PET container for cough syrup delivery resulted in a 35.1% decrease in overall normalized environmental impact.

Research Evidence

Aim: How can standardized eco-design and Life Cycle Assessment (LCA) methodologies be applied to reduce the environmental impact of an industrial product?

Method: Case Study and Comparative Analysis

Procedure: The study followed a six-step eco-design process (ISO 14006:2011), incorporating Life Cycle Assessment (LCA) (ISO 14040, 14044:2006) for environmental impact quantification. A glass container for cough syrup was selected, and its environmental impact was assessed. This was then compared to a redesigned version using a PET container.

Context: Industrial product design, specifically pharmaceutical packaging.

Design Principle

Quantify environmental impact through Life Cycle Assessment to guide material selection and design decisions for maximum sustainability.

How to Apply

When designing new products or redesigning existing ones, conduct an LCA to identify the most environmentally impactful components or stages. Explore alternative materials and manufacturing processes that offer lower impact, and re-evaluate using the LCA.

Limitations

The study focused on a single product type (pharmaceutical packaging) and a specific material substitution (glass to PET), so results may vary for other products and materials.

Student Guide (IB Design Technology)

Simple Explanation: Using a checklist for eco-design and a tool to measure environmental impact (like LCA) helped a team find that switching from glass bottles to plastic ones for cough syrup cut down on pollution by more than a third.

Why This Matters: This study shows how to make products better for the environment by using a systematic process and measuring the results, which is a key part of responsible design.

Critical Thinking: To what extent can the findings of this study be generalized to other product categories and industries, and what are the potential trade-offs associated with PET packaging that were not explored?

IA-Ready Paragraph: This research highlights the effectiveness of integrating standardized eco-design principles with quantitative Life Cycle Assessment (LCA) to achieve significant environmental impact reduction. The study demonstrated that by substituting glass with PET for pharmaceutical packaging, an overall normalized environmental impact decrease of 35.1% was achieved, underscoring the value of data-driven material selection and process optimization in sustainable product development.

Project Tips

• Clearly define the scope of your Life Cycle Assessment (LCA) to ensure all relevant stages are considered.
• Use standardized eco-design frameworks to structure your design process and decision-making.

How to Use in IA

• Reference this study when discussing the importance of quantitative environmental assessment in your design process, especially when exploring material alternatives.

Examiner Tips

• Ensure your chosen eco-design methodology is clearly articulated and that any environmental impact assessments are robust and well-justified.

Independent Variable: Material type (Glass vs. PET)

Dependent Variable: Overall normalized environmental impact

Controlled Variables: Product function (cough syrup delivery container), manufacturing processes (implied comparison of typical production for glass vs. PET containers).

Strengths

• Utilizes standardized methodologies (ISO 14006, ISO 14040/44).
• Provides a quantifiable reduction in environmental impact.

Critical Questions

• What specific environmental impact categories were assessed in the LCA, and were all relevant categories considered?
• How were the 'strategies of improvement' and 'technical solutions' determined in the eco-design process?

Extended Essay Application

• An Extended Essay could investigate the LCA of a chosen product, comparing multiple material alternatives and proposing a design that minimizes environmental impact based on the findings.
