Prioritize Remanufacturing and Reuse for Resource Efficiency

Extending product lifespan through remanufacturing and reuse significantly enhances resource efficiency by leveraging labor to decrease demand for energy and non-renewable materials.

The Canadian Journal of Chemical Engineering · 2022

Key Findings

01Extending product life through reuse and remanufacturing is crucial for resource efficiency, using labor to reduce demand for energy and non-renewable resources.
02The cost penalties for processing end-of-life products to recover individual elements increase rapidly with decreasing material concentration and increasing material complexity.
03Shifting to a closed-loop material system requires rethinking product design to minimize the number of materials used.

Application

Design takeaway

Design products to be easily disassembled, repaired, and upgraded to maximize their lifespan and minimize the need for virgin materials.

How to apply

When designing a new product, explicitly consider how it can be disassembled, repaired, or upgraded at the end of its initial use phase. Evaluate the potential for remanufacturing components or the entire product.

Project actions

01When designing a product, think about how it can be taken apart and put back together again.
02Consider using fewer types of materials in your design to make it easier to recycle or reuse later.

Method & Evidence

AimHow can process system analysis, informed by industrial ecology, be applied to model material flows and optimize resource utilization across the use, reuse, remanufacturing, and recycling stages of a product's lifecycle?

MethodProcess system analysis and material flow modeling

ProcedureThe study analyzed material flows from the perspective of industrial ecology, starting with the existing stock of goods and materials in the economy. It modeled the flows required for the build-up, operation, and maintenance of this stock, developing metrics to quantify the impact of stock growth on material demand. The analysis was illustrated using four metals (lead, copper, aluminum, and lithium) at different stages of industrial maturity.

ContextIndustrial ecology and chemical engineering applied to material product lifecycles.

Variables

IVProduct lifecycle strategies (e.g., linear vs. closed-loop, design for reuse/remanufacturing)

DVResource efficiency (energy, non-renewable materials), cost penalties of material recovery

CVType of material (e.g., lead, copper, aluminum, lithium), maturity of industrial ecology for the material

Strengths & Limitations

Strengths

+Provides a system-level perspective on material flows.
+Quantifies the benefits of reuse and remanufacturing over end-of-life recycling.

Limitations

The complexity of material recovery and the economic feasibility of remanufacturing can vary greatly depending on the product and industry.

Reliability & validity

The study's reliance on process system analysis and modeling provides a robust framework, but the direct empirical validation of all derived metrics across diverse real-world scenarios would enhance its generalizability.

Think critically

How might the 'labor to reduce demand' aspect be quantified and integrated into design decisions, and what are the potential trade-offs with automation?

Design Principles

"Maximize product lifespan and material circularity through design for disassembly, repair, and remanufacturing."

This insight challenges the common focus on end-of-life recycling by highlighting the superior resource and energy savings achievable by keeping products and materials in use for longer. It encourages designers to consider the entire product lifecycle, emphasizing strategies that minimize the need for raw material extraction and processing.

What This Means for Your Design

It's better to fix or reuse products than to just recycle them because fixing uses less energy and fewer new materials.
