Hsinchu, Taiwan, October 11, 2016 - United Microelectronics Corporation (NYSE:UMC; TWSE: 2303) ("UMC"), a leading global semiconductor foundry, today announced that its Hsinchu-based Fab 8A has gained Material Flow Cost Accounting (MFCA) verification in accordance with ISO 14051 by DNV GL, becoming the first MFCA verified semiconductor fab in Taiwan. This achievement demonstrates UMC's success in green management, as the MFCA assessment method exposes the profits hidden in waste and stock and reveals opportunities for waste reduction compared to traditional cost accounting.

UMC Vice President M.L. Liao said, "As a multinational corporate leader, UMC has been following the heated topics regarding worldwide environmental changes. To contribute our part as a responsible global organization, UMC completed product carbon and water footprint assessments and implemented carbon-reduction efforts. We followed these measures by enhancing our upstream control of resources through the implementation of MFCA to minimize loss during manufacturing and completed verification ahead of all others in Taiwan. The new insights gained help us save on raw material and waste treatment costs. For example, using water as a replacement at the soft lithography source can potentially save UMC over NT$20 million per year. This represents a win-win outcome in economic and environmental terms and demonstrates our resolve to care for the environment through concrete action, as pledged in our CSR mission.”

Originating from Germany in the mid-1990s, MFCA focuses on the assessment of the input and output of environment resources, and emphasizes the importance of material losses in the accounting system with the objective of increasing resource production, as well as providing a solution to business profits and current ecological and environmental issues. The assessment system was adopted by the International Organization for Standardization (ISO) as ISO 14051.
