Environmental Sustainability

Energy Conservation and Carbon Reduction Policy

In order to protect the environment, Ingentec not only promotes and implements measures such as water conservation, waste reduction, environmental protection and energy conservation, but also shows its determination to protect the environment with practical actions.

Environmental protection and energy saving measures

In addition to installing a rooftop solar power generation system, Ingentec uses renewable energy to reduce carbon emissions, and also uses LED lamps to save energy and electricity. The factory design is also planned towards a zero-emission and environmentally friendly factory. Electrical appliances are selected for power-saving use. Implement water conservation and waste recycling, so that resources can be fully utilized and reused. In product promotion, promote environmentally friendly products and work with customers to protect the environment. For example, in special gas projects, C4F6 (hexafluorobutadiene) and F2 (fluorine gas) are environmentally friendly with a global warming potential (GWP) of 0. In addition, the patented gas phase etching equipment developed by Ingentec is applied to the surface film removal of semiconductor silicon wafers. In addition to improving the recycling rate of films that are difficult to remove by advanced process control sheets, it helps customers solve a large number of scrap silicon wafers. However, the use of chemicals in the dry process is only 1% compared to the traditional wet process, which fully implements energy saving, environmental protection and carbon reduction.

Rooftop Solar Photovoltaic System

In September 2020, Ingentec built a rooftop solar photovoltaic system. The installed capacity is 145.6 KW. From its commissioning to the end of 2024, it has generated approximately 782,337 kWh of clean energy, which is equivalent to a reduction of approximately 370.828 metric tons of carbon emissions, and equivalent to the annual carbon absorption of approximately 9.5 hectares of natural forest. In addition to using clean energy to generate electricity, the solar power module on the roof can reduce the direct sunlight exposure on the top floor, thereby lowering the indoor temperature and reducing the use of air conditioners.

Annual greenhouse gas emissions, water consumption and total waste weight

Ingentec's direct greenhouse gas emissions are mainly estimated from the direct emissions of gasoline and diesel from Ingentec's transportation vehicles and the fugitive emissions from refrigerants and septic tanks. Scope 2 purchased electricity is the Ingentec's main source of greenhouse gas emissions.

Scope of disclosure: INGENTEC CORPORATION Headquarters and Fab 1

The company discharges no harmful industrial wastewater, only domestic sewage and its discharged water meets the discharge standards, and has no major impact on the local environment.

Water consumption in the past years

Scope of disclosure: INGENTEC CORPORATION(Individuals). Ingentec Fab2 was officially put into operation in January 2024. As Ingentec Fab3 is still under construction, there is no water consumption data available.

No hazardous industrial waste is produced during the Ingentec's manufacturing process. The main waste is the general domestic waste of employees and waste produced in the office. The waste is entrusted to legal removal companies for removal and treatment, and there is no significant impact on Ingentec's operating environment. Since the amount of waste produced is not large, there is no detailed scale and weight measurement, so we have to make a rough estimate based on the contract with the waste removal company.

Total waste in the past years

Description: Clean up types of employee domestic garbage, waste plastic mixtures, waste wood pallets, waste fibers or other cotton, cloth and other mixtures
Disclosure scope: INGENTEC CORPORATION(Individuals). Since Ingentec Fab2 was officially put into operation in 2024, the 2024 waste data covers both Ingentec Fab1 and Fab2.
