- Abstract
- Maximum Achievable Control Technology (MACT) and LifeCycle Assessment (LCA) provide alternative methods for controlling Hazardous Air Pollutants (HAPs). This paper evaluates the application of MACT and LCA as general strategies to reduce HAP emissions within the specific context of the primary aluminum industry. MACT is a "end-of-pipe" control based approach. It is derived from the emissions baseline and the control technologies used by the top 12% of the best controlled sources within a given source category. LCA is a pollution prevention approach that focuses on the "cradle to cradle" multimedia environmental inputs, outputs, and impacts of a product or process. This technical paper concludes that MACT is the most effective immediate strategy to control HAPs. LCA is effective as a means of reducing HAPs, however, is limited by its tradeoff of data quality for data quantity, and its lack of environmental models to evaluate environmental impacts. A model for streamlining LCA using MACT data is demonstrated, and an overview is provided for MACT and LCA methods.
