Key Findings
- 01Resource Efficiency and Waste Minimization (32.5%) and End-of-Life Planning (27.8%) are the most frequently assessed circular strategies using LCA.
- 02Construction (38%) and Automotive (32%) sectors show high implementation of LCA for circular strategies, particularly for material efficiency and lightweighting.
- 03Product Longevity (10.8%), Circular Business Models (14.2%), and Sustainable Materials (14.6%) are less frequently assessed.
- 04Textiles (8%), Chemicals (12%), and Marine applications (6%) are underrepresented sectors for LCA in circular design.
- 05Methodological inconsistencies, data limitations, and lack of standardized metrics hinder broader LCA implementation for circular strategies.
Application
Design takeaway
Integrate Life Cycle Assessment early and consistently into the design process to validate the environmental benefits of circular strategies and identify areas for optimization, particularly focusing on resource efficiency and end-of-life considerations.
How to apply
When proposing or evaluating circular design solutions, use LCA to measure their environmental impact, focusing on resource use, waste generation, and end-of-life scenarios. Benchmark against industry best practices where possible.
Project actions
- 01When choosing a design problem, consider one where circular design principles can be applied and where LCA data might be available or obtainable.
- 02If you are evaluating different design options, use LCA to compare their environmental performance.
- 03Acknowledge the limitations of LCA, such as data availability and the complexity of assessing interconnected strategies.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive systematic review using a recognized framework (PRISMA).
- +Analysis across multiple industries and circular design strategies.
Limitations
Gathering comprehensive and accurate data for a full LCA can be challenging within the scope of a typical design project. The complexity of supply chains and end-of-life scenarios can also be difficult to model accurately.
Reliability & validity
The reliability of the findings is enhanced by the systematic review methodology (PRISMA), which aims to minimize bias in study selection and data extraction. Validity is supported by the broad scope of industries and strategies analyzed, providing a comprehensive overview of LCA application in circular design.
Think critically
Given that LCA is most frequently applied to resource efficiency and end-of-life strategies, how can designers effectively advocate for and measure the environmental benefits of less-studied circular strategies like product longevity or innovative circular business models?
Design Principles
"Quantify environmental impact through Life Cycle Assessment to validate and optimize circular design strategies."
Understanding the environmental impact of design choices is paramount for developing truly sustainable products. LCA provides a data-driven framework to evaluate the effectiveness of circular design principles, enabling designers to identify areas for improvement and make informed decisions that minimize resource depletion and waste.
What This Means for Your Design
Using a 'Life Cycle Assessment' (LCA) helps designers understand the full environmental impact of a product, from making it to disposing of it. This is especially important when trying to make designs more 'circular' (like recycling or reusing parts). The study found that LCA is used a lot to check if designs are good at saving resources and reducing waste, but less so for making products last longer or for new business ideas. Some industries use it more than others, and there are challenges in making the assessments consistent.
How to use in your project
- 1.Reference this study when discussing the importance of evaluating the environmental impact of your chosen design strategies, especially if they are circular.
- 2.Use the findings on commonly assessed strategies (resource efficiency, waste minimization, end-of-life) to frame your own design evaluation.
- 3.Discuss the limitations mentioned in the paper as potential limitations for your own design project's environmental assessment.

Paragraph starter
The application of Life Cycle Assessment (LCA) is critical for validating the environmental efficacy of circular design strategies, as evidenced by a systematic literature review (Falsafi et al., 2025). This research indicates that while LCA is frequently employed to evaluate resource efficiency, waste minimization, and end-of-life planning, its application to product longevity and circular business models is less prevalent. For this design project, LCA principles will guide the evaluation of proposed solutions, focusing on quantifiable environmental benefits and acknowledging the potential for methodological challenges and data limitations.
