Current environmental assessments often fail to capture the full environmental benefits of circular products and business models because they primarily focus on remanufacturing existing products rather than incorporating design for circularity and innovative business models. This sustainability research insight is drawn from a 2020 study published in Journal of Cleaner Production. Using Systematic literature review with 239 papers, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Integrate design for circularity principles and explore product-service system business models to achieve more significant environmental impact reductions than traditional remanufacturing alone.

Key Findings
- 01The majority of environmental assessments focus on remanufacturing existing products and compare it to manufacturing new ones.
- 02Product design strategies for circularity (e.g., design for remanufacturing, upgradability, modularity) and circular business models (e.g., product-service systems) are rarely considered in Life Cycle Assessment (LCA) studies.
- 03There is a lack of studies on products with circular designs utilized within circular business models.
- 04Many assessments are static and do not adequately consider future increases in renewable energy.
Application
Design takeaway
Integrate design for circularity principles and explore product-service system business models to achieve more significant environmental impact reductions than traditional remanufacturing alone.
How to apply
When developing new products or redesigning existing ones, actively consider how the product can be designed for easier disassembly, repair, and component upgrades. Simultaneously, explore business models that shift from ownership to access (e.g., leasing, subscription services) to encourage product longevity and material retention.
Project actions
- 01When evaluating the environmental impact of your design, go beyond just material selection and consider the entire product lifecycle, including design for disassembly and end-of-life scenarios.
- 02Explore how different business models can enhance the sustainability of your product design.

Variables
Strengths & Limitations
Strengths
- +Comprehensive systematic review of a significant body of literature.
- +Identifies specific gaps in current assessment methodologies.
Limitations
Conducting a full LCA for complex circular systems can be time-consuming and data-intensive. Simplified assessments might miss nuanced impacts.
Reliability & validity
The systematic review methodology enhances reliability by ensuring a structured and repeatable process for literature selection and analysis. Validity is addressed by focusing on a specific scope (inner loops) and identifying the limitations of existing studies.
Think critically
Given the limitations of current LCAs, how can designers proactively advocate for and implement circular design strategies that are likely to yield significant environmental benefits, even if they are not fully quantifiable by existing assessment tools?
Design Principles
"Design for Circularity: Prioritize product design that facilitates reuse, repair, refurbishment, remanufacturing, and eventual recycling, and pair this with innovative business models that incentivize resource retention."
Designers and engineers need to understand that simply remanufacturing a product is not the extent of circularity. Incorporating design for disassembly, modularity, and upgradability from the outset, alongside service-based business models, is crucial for maximizing resource efficiency and achieving genuine environmental gains.
What This Means for Your Design
When you try to figure out if a product is good for the environment by being 'circular', most studies only look at fixing up old products. They don't really check if the product was designed to be fixed easily or if the way it's sold (like renting instead of buying) helps the environment more.

Paragraph starter
This research highlights a critical gap in current environmental impact assessments for circular products and business models. While many studies focus on remanufacturing, they often overlook the profound influence of design strategies for circularity (e.g., modularity, upgradability) and innovative business models like product-service systems. Therefore, a comprehensive evaluation of a product's environmental performance within a circular economy necessitates a holistic approach that integrates both design for circularity principles and the associated business model.
