“LCA to go” - Environmental assessment of machine tools according to requirements of Small and Medium-sized Enterprises (SMEs)CASE Study EDM Carl Diver, CDAMC Rainer Pamminger,Vienna University of Technology, Institute for Engineering Design
Background • Vienna University of Technology • Basis research on Sustainable Product Development, EU-Projects • Development of methodologies • Education, University eLearning course, etc. • Information plattform www.ecodesign.at • ECODESIGN company – Spin-off • Strategy for sustainable product development • Product improvement • LCA, Product Carbon Footprint • Company trainings • www.ecodesign-cmpany.com
Analysis of Environmental Impacts ECODESIGN+ guides you through the assessment process, illustrates your results, helps developing eco products!
Why? We are facing three crisis… • Climate ChangeGlobal WarmingFloodings, etc. • Energy crisis volatile Oil priceOld infrastructureInvestment 350 Bill.$/a neededavailability/demand • Nutrition crisesgrowing energy plants There is a need for ECO-intelligent products?

Advantages through ECODESIGN • Derive new product ideas • Improve environmental performance of own products and communicate it • beneficial cost structures Sustainability of the company
LCA to go Boosting Life Cycle Assessment Use in European Small and Medium-sized Enterprises • 18 partners from 9 countries • Duration: January 1, 2011 – December 31, 2014 • funding from the European Union Seventh Framework Programme (FP7) under grant agreement n° 265096 Challenges to develop LCA tools to • Enhance credibility - robust, reliable, transparent: Methodology • Easy to use: Provide easy-to-use tools (lower barrier for acceptance)
LCA to go Target sectors • Industrial machinery • Sensors • Smart textiles • Renewable energy • Bio-based plastics • Electronics • Semiconductors • Passive Components • Printed Circuit Boards
CDAMC • Established January 2008 • Based in Donegal • Research & Development Consultancy – Manufacturing • Special focus on micro-machining • Products- Diesel Fuel Injection Systems • Customers – Delphi Diesel Systems, Continental Automotive, … • National & European Funding support services
CDAMC & LCA to go • Previous LCA experience • SME partner • Working closely with Technical University of Vienna’s ECO design group • Focus on Industrial Machines • Case study SME’s • Identified one of our suppliers in the Automotive sector • Posalux EDM machine manufacturer - Switzerland
Posalux - EDM • Design and Assembly • Process Development • Industrial Machines • No previous LCA experience or expertise • Supplier to Delphi, Continental, Bosch, Denso, …
Posalux – Small Holes These machines are used to drill micro holes from 50μm up to typically 300μm in 1mm thick diesel fuel injection nozzles
Software flow PRODUCT Definition STEP 1: Rough analysis: CED, entire life cycle “The CED is an environmental indicator, which describes the primary energy needed by a process.” STEP 2: Detailed analyses: Relevant life cycle phases CED in detail IMPROVEMENT STRATEGIES for SME Energy and Materials CED…Cummulative Energy demand
Step 1 Rough assessment -Result • Hot spots • Materials, Use • -> included in Step 2 • improvedataquality • deriveimprovements
Step 2: Detailed assessment – Gathering data: Raw materials Goal: - improve data quality - derive improvements
Iterations • Breakdown of each component and its weight in Kg • The breakdown of the calculated energy consumption from Posalux • To calculate the energy consumption due to the assembly of the machine we worked out that they should calculate their electricity consumption for their shop floor and the number of machines produced. – first indication • They calculate 20 years for the product life
Gathering data: use phase • Typical usage scenario • How many days per week • Hours per day • Planned maintenance • Typical Uptime (taking into consideration unplanned stoppages) • Active Power (kW), Apparent Power (kVA), Current Consumption (A)
Iterations We had a number of iterations where Posalux supplied information and we had to go back and clarify certain aspects. Areas like the definition of : • stand-by • Idle • In operation • Taking into consideration down time due to planned maintenance and un-planned stoppages. • Calculating a figure for time in operation based on different customers 24/7 or 5 days a week with 2 shifts
Step 2: Detailed assessment – Result CED…Cummulative Energy demand
Predominat phase - Use • Posalux predominantly carry out assembly operations • They design & assemble the machine but buy standard equipment • From the analysis of the information provided the USE phase is the dominant phase
Recommendation “Any improvement strategies should foremost be focused on the use phase. Improvements to the electricity and compressed air consumption when the machine is “In production” have the highest impact potential.”
Next Steps • Launch Industrial Machines software later in 2013 • Sign-up SME’s to test the software and receive free training • Continue disseminating information • Paper accepted to 30th IMC conference in UCD in September • Software demonstration at Hanover EMO Messe in September
