Establishing the enterprise through integrity, improving through
governance, and achieving long-term success through stability
Over more than two decades of steady development through challenges, Mingtai Aluminum has moved from the
heartland of Central China to the global stage, consistently embedding “integrity” deep within its corporate DNA. Integrity
is our solemn commitment to shareholders, the bottom line of compliance operations, and the highest standard of
business ethics. In the ever-changing market environment, we steer with sound corporate governance and sail with
rigorous risk management, integrating the concept of "improving through governance" into every decision and every
process. Those who do not plan for the long term are unfit to plan for the short term; Those who do not consider the
overall situation are unfit to manage a single part. We deeply understand that excellence is not a momentary brilliance
but long-term stability.

Ecosystem and Biodiversity Protection
Ecosystem and Biodiversity Protection
Soil and groundwater self-monitoring
In order to prevent soil and groundwater contamination, the Company has implemented key protective measures in all areas where leaks could potentially occur. For
example, hazardous waste warehouses, chemical storage areas, oil depots, etc. have undergone rigorous anti-seepage, anti-leakage and anti-corrosion treatment in
accordance with national standards. Simultaneously, the Company has formulated strict material management and operating procedures, along with regular
inspection and monitoring systems. Once potential risks are identified, immediate action is taken, preventing pollution incidents at the source.
Ecosystem and Biodiversity Protection
The Company promises to strictly abide by the ecological conservation redline and, in line with requirements such as the “China National Biodiversity Conservation
Strategy and Action Plan (2023-2030)”, integrating biodiversity protection concepts into its corporate management.
Scientific and prudent project site selection
When making investment decisions for new projects, the Company mandates an ecological environment assessment as a prerequisite.
Recent investments in high-end transformation projects such as Yirui New Material and Hongsheng New Material have been sited within
government-planned industrial parks and have undergone rigorous environmental impact assessments. The Company ensures that the
project locations are far away from ecologically sensitive areas such as nature reserves, drinking water source protection zones and
important wetlands, so as to avoid disturbance to vital ecosystems.
Full-cycle environmental impact assessment
For newly-built projects, the Company not only meticulously analyzes the potential impact of pollutant emissions on the surrounding
ecosystems during the EIA phase, and develops practical control measures, but also continuously monitors during the operational phase to
ensure that all pollutants can be discharged stably up to standard and minimize the impact on the surrounding ecological environment.
Creating a green ecological plant area
The Company actively carries out greening work in its existing production plant area, planting trees and lawns, which not only beautifies the
working environment, but also provides habitat for local micro-ecosystems, striving to build the plant into a garden-like green enterprise.
The Company strictly adheres to the “Convention on Biological Diversity”. While
pursuing economic benefits, it always upholds ecological protection as a fundamental
principle throughout project decision-making, construction, and operation. We strive to find Scientific pest control
