• Environmental Management System

Macronix has been certified by the internationally recognized ISO 14001 environmental management system in August of 1997 and has established environmental standards across all levels within our management system. Internal and external audits are carried out annually to ensure that all aspects of the environmental management system are implemented by the ISO system of PDCA (Plan-Do-Check-Act). We are equally committed to ensure the health and safety of the environment and continually improving our environmental programs.

• Ecological Sustainability and Education

Macronix's aim of eco-design is implemented by spending large amounts of resources to maintaining an area of nearly six hectares into a green grass covered park – Macronix Park. There are up to 1500 trees and other plants in the park including banyan trees, camphor tree, bamboo, and Taiwan acacia trees...etc, to name a few. Additionally, there is also a wide variety of water plants including yellow water lilies, duckweed, and Typha orientalis Presl...etc, there is always something different for every season of the year.

Macronix Park is open to the public and has become the main spot for Hsinchu schools and eco-awareness organizations to hold eco-efficiency education and training programs. Beginning from 2004, Macronix Park has received "Outstanding Landscape Award" from Hsinchu Science Park Administration for many years.

 
 
 
 
 
 
 
 
 
 
 
• Energy and Water Conservation and Waste Reduction

To uphold the principle to sustainable development and advance toward the goal of high-efficiency, low-emission green manufacturing facility, Macronix International Co., Ltd. (the “Company”) continuously implements various initiatives focused on energy saving, water conservation, and waste reduction. The exceptional performance of the Company in those areas has earned many awards from the Environmental Protection Administration of the Executive Yuan, the Water Resources Agency, the Bureau of Energy, and/or the Industrial Development Bureau of the MOEA.





Management Approach	Water Resource Management	Waste Management
Impacts	Actual impact: Via water quality control and reuse Potential impact: Reduce environmental load and impact	Actual impact: Promote waste reduction and recycling/reuse to comply with regulatory requirements Potential impact: Continuously reduce the environmental impact of production, the costs incurred have increased due to the need to comply with increasingly stringent regulatory requirements.
Short-term development direction	Reduce environmental load and environmental impact	Source-segregated waste reduction
Medium and long term development direction	Actively develop wastewater recycling technology to increase the efficiency of water resource use	Develop waste recycling and reuse technology
Management method (Including measures)	External: Hsinchu Science Park Bureau water use plan review, wastewater (sewage) testing report Internal: ISO14001 Manual/Procedure/Specifications/Records	External: Industrial waste reporting and management information system Internal: ISO14001 Manual/Procedure/Specifications/Records
Tracking the effectiveness of the actions	External: 1. Water volume statistics are compiled and the water balance chart is reported on a monthly basis 2. Periodically monitor effluent water quality and outsource effluent testing once every six months Internal: Implement total quantity control and install monitoring instruments that comply with regulations; record and retain data according to the legally mandated frequency and items for future reference	External: 1. Compile statistics of waste storage, production, and clean-up and removal on a monthly basis 2. Audit waste disposal companies on an annual basis Internal: Perform internal inspections and audits on a quarterly basis
2024 Implementation Results	Process water recycling rate in the 8-inch wafer fab was 84.06% (target ≧ 82%) Process water recycling rate in the 12-inch wafer fab was 88.10% (target ≧ 85%) Average process water recycling rate of all fabs in the Company was 86.70% Water consumption per wafer was 0.19 (m3/12-inch equivalent wafer mask layer) Water recycling rate certification statement: FAB2 ( 2024 2023 ) FAB5 ( 2024 2023 )	Reach the Company-wide waste recycling and reuse rate of 97.75% (target ≧ 95%) Reach the Company-wide hazardous waste recycling/reuse rate of 99.82% (target ≧ 98%) Back-end operation plant landfilling rate was 0.20%
Targets in 2025	Process water recycling rate in the 8-inch wafer fab ≧ 82% Process water recycling rate in the 12-inch wafer fab ≧ 85% Water consumption per wafer ≦ 0.266 (m3/12-inch equivalent wafer mask layer)	Reach the Company-wide waste recycling and reuse rate of ≧95.5% Reach the Company-wide hazardous waste recycling/reuse rate of ≧ 98%
Future goals (Short-, Mid-, and Long-Term)	Process water recycling rate exceeds the standard of process water recycling rate established by the Hsinchu Science Park Bureau	Prioritize zero landfill for back-end operation plant

• Greenhouse Gas Management

Concerning the global trends of greenhouse gas (GHG) reduction and Greenhouse Gas Emission Reduction and Management Act i​n Taiwan, Macronix began planning GHG emission inventory and verification in 2000 and was the first company to receive GHG Emission Verification in Hsinchu Science Park. In 2007, Macronix passed the verification by British Standards Institute (BSI) and received the “ISO 14064-1 Greenhouse Gas Verification Statement.” From 2011, Macronix has passed the verification every year, and received the “ISO 14064-1 Greenhouse Gas Verification Statement.” Macronix’s carbon dioxide emission in 2018 reduced 9.3% compared to 2011.

• Green Purchasing

In accordance to conserving our environment and recycle trends, Macronix will only purchase appliances such as energy efficient light bulbs, drinking water fountains, personal computers and peripheral equipment with the Environmental Protection Administration’s "Green Mark" or the Ministry of Economic Affair’s "Energy Label“ and "Water Conservation Label.” We have excelled ourselves in fulfilling the corporate social responsibility. Our efforts have been recognized by the government as evidenced in multiple awards we have received.
