The concept of life-cycle assessment is to evaluate the environmental effectsassociated with any given activity from the initial gathering of raw materialfrom the earth until the point at which all residuals are returned to the earth. This concept is referred to as "cradle to grave" assessment. A frameworkof life-cycle assessment usually consists of four components: Goal and Scope Definition, Inventory Analysis, Impact Assessment and Interpretation. In which,the well-developed inventory analysis component poses almost no difficulties inrealistic practices. The component of impact assessment, however, needs a relatively greater amount of research and development efforts. The study implements a framework for life-cycle assessment which incorporatesmethodologies of environmentalrisk assessment. A case study on corrugated board production is carried out by using the data provided by the Cheng Loong Co., Ltd. The assessment framework consists generally of three components: environmental issue identification, classification and assessment, and integrated evaluation. The identification of environmental issue can adopt principally the environmental aspect used in inventory analysis. The assesmentof environmental impacts, which applies risk assessment concept, is classified as aspect human health effects, ecosystem deterioration, and affect of life quality. The integrated environmental risk index is obtained in the evaluation. It will be helpful to producer choosing the lighter corrugated board by using multiplicative analytic hierarchy process for production decision making process incorporates result of life cycle assessment.
