Simplification of pcr for Printed products 20120930

  1. 1. Nagata Laboratory, Waseda University Graduate School of Environment and Energy EngineeringSimplification of PCR for Printed products Carbon calculation by10-selected item Dr. SHIMIZU, Hirokazu President, SHIMIZU PRINTING INC. Visiting Senior Researcher, Waseda University Environmental Research InstituteExpert, ISO130 (Graphic technology) WG11(Environmental impact of printed matters) 1
  2. 2. Waseda University Environmental Research Institute Motivations 1. Complicated PCR should be reformed • Time-consuming work is big wall for SMEs • Detailed calc. is not equal to “Sophistication” 2. New thought by new CFP program holder • CFP should be utilized for “business” • More than one PCR can exist for same product 3. New concept for SMEs • Carbon calculator can be PCR • Reduce manpower for calculating workShimizu Printing Inc. 2
  3. 3. Waseda University Environmental Research Institute Agenda 1. Promotion of new PCR for Printing • Select only 10-item for simplification • Points of modifying current PCR • Accuracy of PCR for Printing by case studies • Conclusion of new PCR accuracy 2. Accuracy of existing PCR for Printing • The difference by emission factors of paper • The difference by calculation methods • Conclusion of current PCR accuracy 3. Summary • Magnitude of fluctuation of new/current PCR • Utilization of CFPShimizu Printing Inc. 3
  4. 4. Waseda University Environmental Research Institute 1.Promotion of new PCR for Printing (cont’d) Select only 10-item for simplification (1)Substrate NOT calculated (2)Transportation for substrate Water (dampening solution) (3)Ink & varnish Additive (dampening solution) (4)Transportation for Ink & varnish (5)Plate (waterless printing) (6)Transportation for Plate Prepress(editing, designing, CtP) (7)Printing process (waterless printing) (8)Post-press process Material (glue, stitch...) (9)Distribution Wrapping material for delivery (10)Waste & RecycleShimizu Printing Inc. 4
  5. 5. Waseda University Environmental Research Institute 1.Promotion of new PCR for Printing Points of modifying current PCR I. Calculation method is unified for “cumulative” II. Modelization for thickness of ink/varnish III. Electricity usage = Rated output × fixed loading factor IV. Loading percentage of truck is fixed at 50% V. Calculate incineration by coated layer of paper only VI. Printed products only by waterless printing method VII.Avoid “scenario setting” of key itemsShimizu Printing Inc. 5
  6. 6. 1.Substrate (paper/plastic) 2. Trans. for Substrate (trucks/rail/surface/air)Shimizu Printing Inc. Raw material acquisition 3.Ink & varnish (conv./UV ink, OP varnish, Coating varnish) 4.Trans. for Ink & varnish (trucks/rail/surface/air) 5.Plate (for waterless printing)6 6.Trans. for Plate (trucks/rail/surface/air) Points of modifying current PCR 7.Printing process (electricity for machines, lighting, air-cond.) Production 8.Postpress process (electricity for machines, lighting, air-cond.) 1.Promotion of new PCR for Printing 9.Delivery (excluding packing materials) Distribution (cont’d) 10.Waste from household, Recycle from factory and household Waste/ Waseda University Environmental Research Institute Recycle

  19. 19. Waseda University Environmental Research Institute 3.Summary (cont’d) Utilization of CFP by simplification of PCR a. Find “Hotspot(s)” to improve manufacturing process and/or select eco-friendly material b. Communicate with print-buyers (consumers) by showing comprehensive internal comparison c. Conduct many pilot projects to know efficiency of CFP (environment impact assessment) CFP should be utilized for sales growth and cost-cut, not for academic experts to be satisfied Simplification of calculation is extremely important to save time and money, “Detailed calculation cannot guarantee accuracy!”Shimizu Printing Inc. 19
