Delft University of Technology Industrial Design Engineering Design for Sustainability Program Eco-Efficiency of Take-Back and Recycling A comprehensive and quantitative approach Jaco Huisman, Ab Stevels
2
Delft University of Technology Industrial Design Engineering Design for Sustainability Program Outline 1.Methodology –QWERTY: Recyclability from an environmental perspective? –EE: Eco-Efficiency: Relation environment and economics? 2.Requirements 3.Examples 4.Eco-efficiency directions 5.Conclusions
3
Delft University of Technology Industrial Design Engineering Design for Sustainability Program Why QWERTY? (Quotes for environmentally Weighted RecyclabiliTY) General Idea: Replace ‘weight’ by ‘environmental weight’: Environmental value of disposed products Optimal recycling routes Priorities of different materials How effective are proposed recycling targets and treatment rules? Environmental description of the end-of-life chain
4
Delft University of Technology Industrial Design Engineering Design for Sustainability Program QWERTY: Basic Idea
5
Delft University of Technology Industrial Design Engineering Design for Sustainability Program Why Eco-Efficiency of End-of-Life? Authorities/ Legislators Meaningful criteria Policy per product category Monitor performance Designer Evaluate (re)design NGO’s/ Customer organizations Green demands and corresponding price tags Producers Calculate End-of-Life costs Audit recyclers Consumers Environmental value for money Recyclers Calculate tariffs Technology improvement Economic description of the end-of-life chain
6
Delft University of Technology Industrial Design Engineering Design for Sustainability Program How to Quantify Eco-Efficiency?
7
Delft University of Technology Industrial Design Engineering Design for Sustainability Program Requirements Data (Dutch take-back system): 1.Product compositions 2.Disassembly/ shredding and separation 3.LCA methods and standard databases 4.Collection rates, transport distances, costs 5.Recovery processes: metal smelters etc. 6.Final waste processing: emissions and penalties

Delft University of Technology Industrial Design Engineering Design for Sustainability Program Plastic recycling versus size of housings
15
Delft University of Technology Industrial Design Engineering Design for Sustainability Program Eco-efficiency directions
16
Delft University of Technology Industrial Design Engineering Design for Sustainability Program Eco-efficiency directions: ENCOURAGE Direction: 1.Increase collection rates precious dominated products 2.Separate collection system for precious dominated products 3.Plastic recycling large sized housings, already disassembled
17
Delft University of Technology Industrial Design Engineering Design for Sustainability Program Eco-efficiency directions: AVOID Direction: 1.Incineration without energy recovery 2.Residue fractions with low plastic content send to the cement industry
18
Delft University of Technology Industrial Design Engineering Design for Sustainability Program Eco-efficiency directions: BALANCE High priority Low priority
19
Delft University of Technology Industrial Design Engineering Design for Sustainability Program Conclusions (Policy Strategies) Problem: End-of-life treatment has to do with material compositions and not with categories Solution: Review (current EU) policy strategies 1.Drastically review recycling targets 2.Apply differentiated collection rates 3.Apply certain outlet rules 4.Discard most of the current treatment rules and apply certain new ones
20
Delft University of Technology Industrial Design Engineering Design for Sustainability Program Further applications 1.Audit and improve recycler performance 2.Monitoring take-back systems as a whole 3.Evaluate design strategies and life-cycle perspective 4.Award good ecodesign of individual products in a collective system 5.Broader regional and product scope
