Institute for Sustainable Manufacturing Faculty Publications

Sustainability in manufacturing can be evaluated at product, process and system levels. The 6R methodology for sustainability enhancement in manufacturing processes includes: reduced use of materials, energy, water and other resources; reusing of products/components; recovery and recycling of materials/components; remanufacturing of products; and redesigning of products to utilize recovered materials/resources. Although manufacturing processes can be evaluated by their productivity, quality and cost, process sustainability assessment makes it a complete evaluation. This paper presents a 6R-based evaluation method for sustainable manufacturing in terms of specific metrics within six major metrics clusters: environmental impact, energy consumption, waste management, cost, resource utilization and …


Sustainable Manufacturing Performance Evaluation: Integrating Product And Process Metrics For Systems Level Assessment, Aihua Huang, Fazleena Badurdeen Mar 2017

Sustainable Manufacturing Performance Evaluation: Integrating Product And Process Metrics For Systems Level Assessment, Aihua Huang, Fazleena Badurdeen

This paper builds on the previously developed product sustainability index (ProdSI) and process sustainability index (ProcSI), and presents a framework for sustainable manufacturing performance evaluation at the systems level. The framework is then used to propose a comprehensive set of metrics for the enterprise level following a five-stage metrics hierarchy (individual metrics, sub-clusters, clusters, sub-index and index). The 6R concept (reduce, reuse, recycle, recover, redesign and remanufacture), total life-cycle emphasis, and triple bottom line (TBL) are considered for selecting relevant metrics. Finally, the metrics are integrated to develop an index for enterprise level sustainability assessment and …
