Method: Life Cycle Assessment (LCA)
Evidence: Strong effect

Remanufacturing impellers offers a significantly more sustainable production pathway compared to conventional or additive manufacturing, drastically reducing global warming potential, resource depletion, and eutrophication. This resource management research insight is drawn from a 2017 study published in Journal of Industrial Ecology. Using Life cycle assessment (lca), researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for production, actively consider and evaluate remanufacturing as a primary option for component lifecycle management due to its superior environmental performance.

Remanufacturing Impellers Cuts Environmental Impact by Over 60%

Journal of Industrial Ecology · 2017

Key Findings

01Remanufacturing (RM) is the most environmentally favorable option across all assessed impact categories.
02Additive Manufacturing (AM) can sometimes have a higher environmental burden than Conventional Manufacturing (CM), with pure AM production being approximately twice that of CM in this case.
03RM of impellers can reduce GWP by 64.7%, CADP by 66.1%, and EP by 75.4% compared to CM.

Application

Design takeaway

When designing for production, actively consider and evaluate remanufacturing as a primary option for component lifecycle management due to its superior environmental performance.

How to apply

When specifying manufacturing processes for new product development or for existing product lines, integrate LCA data to quantitatively compare the environmental footprint of remanufacturing versus new production methods.

Project actions

01When researching manufacturing methods for your design project, look for studies that compare the environmental impact of different options.
02Consider how your design choices might enable future remanufacturing or recycling.

Method & Evidence

AimTo compare the environmental impacts of conventional manufacturing (CM), additive manufacturing (AM), and remanufacturing (RM) for impellers using a life cycle assessment (LCA) methodology.

MethodLife Cycle Assessment (LCA)

ProcedureThe study conducted a comparative LCA of three impeller production methods: plunge milling (CM), laser cladding forming (AM combined with CM), and additive remanufacturing (RM). Environmental impacts, including global warming potential (GWP), Chinese resource depletion potential (CADP), water eutrophication potential (EP), and acidification potential, were quantified for each method.

ContextTurbomachinery components (impellers) in petrochemical and aeronautical engineering.

Variables

IVManufacturing method (Conventional Manufacturing, Additive Manufacturing, Remanufacturing)

DVEnvironmental impact metrics (Global Warming Potential, Resource Depletion Potential, Eutrophication Potential, Acidification Potential)

CVImpeller type, specific manufacturing processes used within each category, material properties.

Strengths & Limitations

Strengths

+Utilizes a robust Life Cycle Assessment (LCA) methodology.
+Provides quantitative comparisons of environmental impacts across different manufacturing approaches.

Limitations

The specific percentages of environmental benefit are tied to the exact methods and materials studied. Your own design project might use different materials or processes, so the exact numbers may differ.

Reliability & validity

The reliability of the LCA depends on the accuracy of the data inputs for each manufacturing process. Validity is supported by the use of established LCA methodologies and metrics.

Think critically

Under what conditions might additive manufacturing become more environmentally beneficial than conventional manufacturing, and how could design choices influence this outcome?

Design Principles

"Embrace circular economy principles by designing for disassembly, repair, and remanufacturing to minimize virgin resource consumption and waste generation."

This research provides critical data for design and manufacturing professionals to make environmentally conscious decisions. By quantifying the benefits of remanufacturing, it enables the selection of processes that align with sustainability goals and reduce the ecological footprint of critical components like impellers.

What This Means for Your Design

Making old impellers new again (remanufacturing) is much better for the planet than making them from scratch using old or new methods. It uses way fewer resources and creates less pollution.
