Unlinear Methodology: Designing for Circularity in Garments and Footwear

A structured approach to product design can significantly improve material recovery and recycling at the end of a product's life.

Key Findings

  • 01The design of garments and footwear presents significant complexities for dismantling and recycling due to material diversity and assembly methods.
  • 02A standardized product representation tool, detailing component materials and functions, can aid in redesigning products for better circularity.
  • 03The proposed 'Unlinear' methodology aims to simplify material recovery and recycling processes at the product's end-of-life.
02

Application

Design takeaway

Integrate a component-level material and function mapping process into the design workflow to proactively plan for product disassembly and material recovery.

How to apply

When designing new products or redesigning existing ones, create a detailed bill of materials that includes not only the material of each component but also its primary function and how it is attached. Use this information to identify components that hinder disassembly or recycling and explore alternative materials or assembly methods.

Project actions

  • 01When starting a design project, think about what will happen to the product after it's used.
  • 02Consider how easy it will be to separate different materials for recycling or reuse.

Method & Evidence

AimHow can a standardized product representation tool, detailing material and function of each component, facilitate the redesign of garments and footwear for improved circularity?
MethodMethodology Development and Application
ProcedureThe research proposes and outlines the 'Unlinear' methodology, which utilizes a standardized representation of product components, their materials, and functions. This representation is intended to guide design teams in redesigning products, specifically garments and footwear, to enhance material recoverability and recyclability at end-of-life.
ContextProduct design, particularly for garments and footwear, with a focus on end-of-life management and circular economy principles.

Variables

IVProduct design methodology (Unlinear vs. traditional)
DVEase of material recovery and recycling
CVProduct type (garments/footwear), material types, assembly methods
04

Strengths & Limitations

Strengths

  • +Addresses a critical gap in product design by focusing on end-of-life.
  • +Proposes a structured, actionable methodology for designers.

Limitations

It can be challenging to get detailed information about the exact materials and construction methods of existing products without direct access to manufacturing data.

Reliability & validity

The reliability of the methodology depends on the consistency of the component mapping process. Validity is supported by the logical connection between detailed product information and improved end-of-life outcomes, though empirical testing would strengthen it.

Think critically

To what extent can a purely digital representation of a product's components and materials fully capture the complexities of real-world disassembly and recycling processes?

05

Design Principles

"Design for Disassembly and Material Recovery: Products should be designed with consideration for how they will be taken apart and how their constituent materials can be recovered and reused or recycled."

Traditional product design often overlooks end-of-life considerations, leading to material waste and complex recycling challenges. Implementing a circular design methodology, like the Unlinear approach, empowers design teams to proactively address these issues, fostering a more sustainable product lifecycle.

06

What This Means for Your Design

This research suggests a way to design things like clothes and shoes so they are easier to take apart and recycle when you're done with them. It involves making a detailed map of all the parts, what they're made of, and what they do.

How to use in your project

  • 1.Reference the 'Unlinear' methodology as a framework for analyzing the end-of-life potential of your design concept.
  • 2.Use the concept of component mapping to justify material choices and assembly methods in your design process.

Paragraph starter

The 'Unlinear' methodology, as proposed by Demarcq et al. (2022), offers a valuable framework for designing products with end-of-life considerations in mind. By creating a standardized representation of product components, their materials, and functions, designers can proactively address challenges in material recovery and recycling, particularly for complex items like garments and footwear, thereby contributing to a more circular economy.
