Evaluating risks of new substances in electronic products: using an abridged lifecycle assessment-analytic hierarchy process (ALCA/AHP) computer-based tool

This paper describes the development and use of a methodology which combines two modeling approaches for the purpose of evaluating the impacts created by new materials in electronic products. This technique utilizes Abridged Lifecycle Assessment (ALCA) thinking combined with a computer-based Analytic Hierarchy Process (AHP) tool. Through this approach, an abridged lifecycle analysis can be integrated with company-specific attitudes and preferences on the importance of each life stage in the ALCA. The result is a useful and justifiable evaluation of new materials proposed for incorporation into a product or process. Rather than offering a definitive answer for deciding between materials, the tool offers decision makers additional assistance in identifying and evaluating conflicting objectives. Examples of applications are provided.
