  • 1. © M. Jutz-Effizienzagentur Schweiz AG      Can  3D  Prin*ng  Go  Green?      producing  be5er  products  with    less  resources  and  impact      Prof.  Maurice  Jutz  Swiss  Centre  for  Efficiency  Ltd      
  • 2. 2Content  •  Introduction•  Eco-efficiency and sustainability - key points for the design of newproducts and processes•  How much do we have to reduce our resource consumption whenglobal population reaches 10 billions => IPAT calculator•  Life Cycle Assessment: a powerful tool to evaluate theenvironmental impact of products and processes•  What are the most important key factors to be respected in order tobe able to say : ”3-d printing is sustainable”?

  • 15. 15Ecological footprintsource: Global Footprint NetworkThe Ecological Footprint is an accounting system that tracks, on the demand side(Footprint), how much land and water area a human population uses to provide allit takes from nature. This includes the areas for producing the resource itconsumes, the space for accommodating its buildings and roads, and theecosystems for absorbing its waste emissions such as carbon dioxideSource: http://www.footprintnetwork.org/en/index.php/GFN/page/footprint_basics_overview/

  • 17. 1717Cleantech Masterplan Switzerland(2011)The vision is to reduceSwitzerland’s use of resourcesto a sustainable level (footprint1) and so become a leadingbusiness location and centre forinnovation in the cleantechsector. Switzerland will set aglobal example in resourceefficiency and resourcemanagement.

  • 19. 1919SustainabilitySustainable development is development that meets theneeds of the present without compromising the abilityof future generations to meet their own needs. Itcontains within it two key concepts:The concept of needs, in particular the essential needsof the worlds poor, to which overriding priority shouldbe given; andThe idea of limitations imposed by the state of technologyand social organization on the environments ability tomeet present and future needs.Source: Brundtland Report of 1987The drawback to the Brundtland definition is it’s moreinspirational than practical. It’s not precise andmeasurable
  • 20. 20Eco Efficiency"eco-efficiency is achieved by the delivery ofcompetitively priced goods and services that satisfyhuman needs and..bring quality of life, while progressively reducingecological impacts and resource intensitythroughout the life-cycle…to a level at least in line with the Earth’s estimatedcarrying capacity."Source: World Business Council for Sustainable Development (WBCSD)creating more value with less impact
