  1. Asahi Kasei AWP LCA study

  2. Background for the LCA analysis • Global demand of reducing Greenhouse Gas（GHG) emission • First introduction to the flexo printing industry on the FTA 2007 (Montreal, Canada) • Brand owners are the drivers with the aim to improve their environmental impact and drive costs out by reducing energy. • Timberland shoe box packaging

  3. Asahi Kasei LCA methodology for the investigation and calculation • International Accounting StandardsThe basic prerequisite for being able to measure and jointly manage greenhouse gas emissions is to have a scientifically substantiated, transparent and internationally coordinated assessment framework both on the corporate and the product level. And, for the full product life cycle: that is, from manufacturing to use to disposal. Today these assessment standards are under development under the following working document: PAS 2050:2008 (Specification for the assessment of the life cycle greenhouse gas emissions of goods and services) • There are several calculation software packages used around the world such as Gabi, SimaPro, or LCA-Pro（JPN). As there is no global accounting standard today • Conversion ratio of CO2 emission in relation to the Ajinomoto Company material data base was used. • Asahi Kasei E-materials calculation was based on the ISO14040/14044 using JEMAI* methodology • * JEMAI:Japan Environmental Management Association for Industry

  7. AWP LCA conclusion • AWP water wash technology shows the lowest product carbon footprint from “cradle to grave” among the studied technologies • AWP can reduce natural resources by re-using the wash water during plate processing • AWP´s low product CO2 footprint results in a total process cost reduction • Asahi will continue its sustainable approachfor its future product development
