Project actions

01When selecting materials, research their recycling rates and the CO2 emissions associated with their production.
02Consider how easily valuable materials can be accessed and removed from the product.
03Use software that can help you analyze the environmental impact of different material choices.

Method & Evidence

AimHow can disassembly sequences be generated to prioritize components with the highest environmental and economic value for material recovery?

MethodComputational modelling and optimization

ProcedureA CAD-based approach was developed to identify and select parts for disassembly based on criteria such as CO2 saving rate, recycling rate, and material recovery value. This method utilizes information on material properties, weight, and assembly precedence relationships to inform the selection process.

ContextEnd-of-life product management and circular supply chains

Variables

IVCriteria for parts selection (e.g., CO2 saving rate, recycling rate, material recovery value)

DVDisassembly sequence efficiency (environmental and economic metrics)

CVProduct assembly structure, material properties, precedence relationships

Strengths & Limitations

Strengths

+Integrates both environmental and economic considerations for a holistic approach to disassembly.
+Utilizes CAD for a practical and potentially automatable solution.

Limitations

Data on material recovery values and CO2 emissions can be difficult to obtain and may vary by region or supplier. The complexity of real-world disassembly processes may not be fully captured by simplified models.

Reliability & validity

The reliability of the findings depends on the consistency of the data used for CO2 savings and material recovery values. Validity is enhanced by the CAD-based approach, which simulates a practical application, but further validation with real-world disassembly would be beneficial.

Think critically

To what extent can the proposed method account for the variability in material prices and recycling infrastructure across different geographical locations?

Design Principles

"Maximize resource value and minimize environmental impact through intelligent end-of-life material selection."

This approach moves beyond simple recycling to actively optimize resource loops within supply chains. By integrating environmental and economic factors into disassembly strategies, design teams can significantly reduce their product's lifecycle carbon footprint and enhance material circulation.

What This Means for Your Design

Think about what parts of your product are most valuable to recycle and save the most energy when you take it apart at the end of its life. This makes recycling better for the planet and your wallet.
