Sustainable manufacturing A (very) brief overview + evaluation matrix Institute for Sustainable Manufacturing 1 Current Research Focus Areas • • • • • • • Sustainable materials (energy-efficient material design for manufacture: molecular, microstructural and metallurgical transformation of materials; self-healing materials and memory alloys) Sustainable product development (energy-efficient products; sustainability metrics for products; 6R-based product design for sustainability) Sustainable manufacturing processes (energy-efficient, environmentally benign manufacturing process development – toxic-free, hazardless, safe and secure technologies; minimal use of metal working fluids and chemicals; tribological interface science; coatings; surface and sub-surface integrity studies) Sustainable manufacturing systems (metrics for sustainability performance, ontology for interoperability of sustainable supply chains; sustainable quality systems; energy-efficient supply chain operations and manufacturing systems) Society, Public policy and Regulatory issues in Sustainable Manufacturing (Societal Impact studies; legislative and administrative issues; policy implementation; product and process liability; ethics) Sustainable service and health care systems (interdisciplinary work on the interaction between social systems and manufacturing systems) Economic analysis of sustainable products and processes (marketing strategies and business economics for sustainable products and processes) Institute for Sustainable Manufacturing 2 Holistic and Total Life-cycle Approach • Emphasis on all four product lifecycle stages Manufacturing Use Premanufacturing Post-use Institute for Sustainable Manufacturing 3 Closed-loop Material Flow – The 6R Approach 6R 3R CONCEPT CONCEPT NS EN ER G Y IS EM O SI Source: Jawahir et al.

The former includes: manufacturing of renewable energy, energy efficiency, green building, and other “green” & social equity-related products, and, the latter emphasizes: sustainable manufacturing of all products taking into account the full sustainability/total life-cycle issues related to the products manufactured (National Council for Advanced Manufacturing (NACFAM), 2009) Institute for Sustainable Manufacturing 6 Three Major Focus Areas Overall focus on holistic view and integration of sustainability issues at the product, process and system levels across all four life-cycle stages (pre-manufacturing, manufacturing, use and post-use) and considering all three sustainability aspects (environment, economy and society) Products Improved metrics for product sustainability evaluation Product design for sustaibnability Case studies: Autobody sustainability, Suatainability evaluation in laser printers, Sustainable biomedical implants, DfS study of aluminum beverage cans Processes Machining: Improved metrics for process sustainability scoring; Dry, near-dry and cryogenic machining; Improving surface integrity, and hence product life, through machining; Process modeling and optimization Brazing: Experimental development of lead-free soldering; Modeling and optimization of wetting mechanics and joint formation Friction stir processing and Super plastic forming: Experimental development of FSP to produce ultrafine grain materials for superplastic forming of sustainable, light-weight alloys; Process modeling and optimization Institute for Sustainable Manufacturing Systems Sustainable supply chains, and sustainable production and service systems Improved metrics for evaluation of environmental, economic and societal impacts Development of interoperability platforms for sustainable manufacturing 7 Fazleena Badurdeen Sustainable Manufacturing Systems and Supply Chains • Focus: Design and optimization of sustainable manufacturing systems and supply chains to improve economic, environmental and societal performance • Emphasis: – – – – • Total product life-cycle (pre-manufacturing, manufacturing, use and post-use ) focus Closed-loop material flow across the four lifecycle stages Application of 6R’s for sustainable manufacturing • Reduce, Reuse, Recycle, Recover, Redesign, Remanufacture Multiple product life-cycle emphasis Research projects: – – – – – Next Generation sustainable supply chain modeling – developing measurement systems and performance metrics Risk analysis for sustainable supply chains 3rd Lifecycle Coordinated sustainable product and supply & beyond chain design for closed-loop flow Sustainable supplier performance evaluation modeling Product-service system modeling to increase sustainable value-added Reduce sign Rede Rem anuf actu re 2nd Lifecycle Recycle Recover Reuse Pre-Manufacturing Post Use Manufacturing Use 1st Lifecycle Institute for Sustainable Manufacturing 8 Total Life-cycle Evaluation Matrix for Product Sustainability Influencing Factors in the Product Life-cycle Stages Manufacturing Use Pre-manufacturing Score out of 10 Post-use Score out of 10 Score out of 10 Material Extraction 7 Production Energy Used 7 Emissions 9 Recyclability 7 Design for Environment 8 Hazardous Waste Produced 9 Functionality 8 Remanufacturability 8 Material Processing 6 Renewable Energy Used 8 Hazardous Waste Generated 9 Redesign 7 Environment (%) PSI (en_pm) = Sustainability Components Score out of 10 (%) PSI (en_m) = 70 (%) PSI (en_u) = 80 86.67 Landfill Contribution (%) PSI (en_pu) = 7 Worker Health 8 Work Ethics 7 Product Pricing 7 Take-back Options 7 Work Safety 8 Ergonomics 7 Human Safety 9 Re-use 6 Ergonomics 7 Work Safety 8 Upgradeablility 7 Recovery 7 Complaints 8 Society (%) PSI (so_pm) = (%) PSI (so_m) = 76.67 (%) PSI (so_u) = 73.33 77.5 (%) PSI (so_pu) = 6 Production Cost 6 Maintenance Cost 7 Recycling Cost 7 Labor Cost 3 Packaging Cost 7 Repair Cost 6 Disassembly Cost 8 Energy Cost 8 Consumer Injury Cost 8 Disposal Cost 4 Transportation Cost (%) PSI (ec_m) = 5 Consumer Warranty Cost (%) PSI (ec_pu) = 7 Remanufacturing Cost (%) PSI (ec_pu) = 65 (%) PSI (ec_pm) = (%) PSI pm = 45 (%) PSI m = 63.89 65 72.78 70 (%) PSI u = 78.06 (%) PSI pu = 77.29 (%) PSI so = 73.54 (%) PSI ec = 61.25 (%) PSI TLC = 70.69 66.67 Raw Material Cost Economy (%) PSI en = 72.5 7 68.06 Symbol Score Excellent 85-90% Good 70-84% Average 50-69% Poor < 50% Institute for Sustainable Manufacturing 9
