Asahi Kasei AWP LCA study

Background for the LCA analysisBackground 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.

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

AWP LCA conclusionAWP 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
