Circular Design for automotive engineers

The Need for Circular Design - focus on automotive industry
What you'll learn
Apply the ISO 59004 R-hierarchy to choose the highest-value circular strategy for any component.
Implement five core circular design principles: Design for Disassembly, Modularity, Material Selection, Durability, and Maintenance & Repair.
Calculate Total Cost of Ownership (TCO) comparisons that include recovered value and show the business case for circular options.
Create practical disassembly, repair and remanufacture specifications that meet Automotive sustainability is a hot topic. OEMs and suppliers are under pressure to decarbonize and adopt circularity. Engineers are the start point in this journey. Below is the overview of the course content.Disclaimer: This course contains the use of artificial intelligence for audio creation.Section 1: Introduction & The Need for Circular Design This section sets the stage by explaining why circular design is critically important for automotive engineers now, contrasting it with the broken economics of linear design.Introduction to Circular Design:Why Circular Design Matters NOW: Covers the key drivers including Regulatory Pressure (EU ESPR, Right to Repair, EPR), Cost Reality (raw material prices, supply chain disruptions), Market Demand (OEM circularity metrics), Revenue Opportunity (remanufacturing market growth), and Competitive Advantage (early movers).The Problem: Linear Design Economics Are Broken: Highlights the shortcomings of the traditional approach (design for lowest upfront cost, ignoring end-of-life). Discusses Hidden Costs (warranty, disposal, fines, material volatility) and Lost Revenue (95% material value lost in single-use designs). Emphasizes the Engineer's Role in long-term value creation.Section 2: The R-Strategy Hierarchy & Core Principles This section introduces the fundamental framework for circularity - the R-Strategy Hierarchy - and then dives into the five core design principles that engineers can immediately apply.Course Content:The R-Strategy Hierarchy (ISO 59004):Understanding the different R-strategies from R0 (Refuse) to R8 (Recycle), ordered by increasing circularity and value retention.Applying the R-Hierarchy as a Decision Framework: Explains the Priority Order (start at R0, move down only when higher options aren't feasible) and the concept of Value Retention by Strategy Level. Introduces the Decision Tool: "Why can't I apply R0? R1? R2?"Core Circular Design Principles:Core Principle #1: Design for Disassembly (DfD): Defines the target (e.g., 10 min to remove a module), provides an Implementation Checklist (mechanical fasteners, max 3 fastener types, clear pathways, visual indicators, accessible wear components), and an ROI Example.Core Principle #2: Design for Modularity: Sets the goal (component swapping, upgrades), outlines Design Rules (group components by lifecycle, standardized interfaces, forward/backward compatibility, independent testing), and discusses Business Impact (enables PaaS).Core Principle #3: Material Selection Strategy: Prioritizes mono-materials, discusses the Material Decision Matrix (Durability, Recyclability, Recycled Content, Separability), importance of Labeling (ISO 11469), and Cost Reality of recycled materials.Core Principle #4: Design for Durability: Establishes the Mandate (exceed specs by 30-50%), details Engineering Practices (fatigue analysis, environmental testing, designing out failures, corrosion resistance, electronics protection), and presents the Business Case (reduced warranty, PaaS enablement).Core Principle #5: Design for Maintenance & Repair: Defines the Requirement (serviceable part 30 min with standard tools), outlines Implementation steps (access panels, avoid proprietary tools, self-diagnostics, digital manuals, spare parts availability), and highlights Revenue Opportunity from aftermarket parts.Section 3: Circular Business Models, Regulations & Metrics This section delves into how value is created and captured in a circular economy, the essential regulatory landscape, and the metrics needed to track progress.Course Content:Circular Business Models: Where the Money Is:Model 1: Product-as-a-Service (PaaS): Retaining ownership, selling performance.Model 2: Remanufacturing: Taking back, restoring, reselling at a percentage of new price.Model 3: Parts Harvesting: Grading returned units, recombining good modules.Model 4: Second-Life Applications: Repurposing components (e.g., EV batteries for stationary storage).Building the Business Case: TCO Analysis: Compares full lifecycle costs, not just unit price, with an Example Calculation demonstrating significant cost reduction and new revenue streams from circular design.Regulatory Landscape: What You Must Know:EU Ecodesign for Sustainable Products Regulation (ESPR): Requirements (durability, repairability scores, recycled content, DPP), Mandates.Right to Repair Legislation (EU & US states): Requirements (spare parts, tools, manuals), Enforcement.Extended Producer Responsibility (EPR): The "polluter pays" principle and its cost impact.ISO 59000 Series: Framework for measuring circular economy (ISO 59004, ISO 59020).Digital Product Passport (DPP): Your New Design Requirement: Defines what it is (digital twin), Required Data (BOM, manufacturing, lifetime, disassembly, repair history, R-strategies), Implementation (QR/RFID, blockchain/cloud), and Benefits.Key Circularity Metrics to Track (ISO 59004):Material Circularity Indicator (MCI): 0-1 score, target 0.6.Recycled Content %: Minimum targets.Recyclability Rate %: Target 90% by weight.Disassembly Time: 10 min for key modules.Remanufacturability Score.Repairability Index: Accessibility, documentation, spare parts.Tool: Integrate into PLM/CAD workflow.Section 4: Implementation, Overcoming Barriers & Next Steps The final section equips engineers with practical strategies to implement circular design, address common organizational challenges, and outlines a clear path forward.Course Content:Overcoming Barriers: Common Objections & Responses:Addresses objections like "Circular design costs more upfront," "Customers don't care about sustainability," "No supply chain for recycled materials," and "Remanufacturing cannibalizes new sales," providing data-driven Responses.Implementation Roadmap: Your 90-Day Action Plan:Outlines phases: Baseline Assessment (Week 1-2), Quick Wins (Week 3-4), Pilot Project (Week 5-8), Scale & Integrate (Week 9-12), with specific Objectives and Key Actions for each.Practical Exercise: R-Strategy Design Review Checklist: A checklist to guide design reviews using ISO 59004 alignment.Resources & Tools:Lists relevant ISO Standards (59004, 59020, 14001).Mentions Material Databases (GaBi, Ecoinvent, GRANTA MI).Identifies Circularity Assessment Tools (Ellen MacArthur Foundation MCI Calculator, WBCSD Toolkit).Points to Industry Networks (MERA, CLEPA).The Engineer as Change Agent: Emphasizes the significant role of engineers in shaping the automotive industry, creating value, and transforming linear economics.Key Takeaways: Summarizes the core messages of the lecture.Your Next Steps: Provides concrete, actionable tasks for engineers (This week, This month, This quarter) to apply their learning.
