GIGA have closely controlled waste or sewage treatment, ensuring that there is no environmental pollution, outflow to habitats, or impact to ecology or diversity of any species.

Waste can be divided into general industrial waste and hazardous industrial waste. The waste has been centralized, stored, and managed to effectively control the output of waste sources. The waste has been classified as appropriate, and the waste that cannot be recycled is entrusted to be treated by professional, qualified waste organizations according to the best treatment technology corresponding to the waste characteristics. The Company conducts non-periodical follow up to ensure that the waste is properly disposed of, and the hazardous industrial waste is not transported to be treated abroad. We set a waste recycling target to conduct waste management.

Reuse and Reduction of Packaging Materials

We rigorously encourage upstream and downstream vendors to reduce waste by enhancing the recycling and reuse rates of their various packaging materials. Except for specific products of the customers that are not suitable for packaging material reuse, GIGA cooperates with customers to reuse packaging materials of shipments to GIGA for GIGA's future shipments back to the customers. For example, the special wafer cassettes are professionally cleaned and re-used for shipments, and the cartons are reused.

Refuse to Use of Disposable Utensils

Most of the disposable dining utensils are made from fossil materials that produce high amounts of carbon when incinerated. 75% of disposable chopsticks contain bleach, sulfur dioxide, hydrogen peroxide and a number of chemical substances that are harmful to our health. As GIGA believes in the idea that “health comes to those who are friendly to the environment” and “to refuse disposable dining utensils”.

The polluted water is mainly discharged from the wastewater of the cooling water tank operated for the fab's air-conditioning and general domestic water. All sites waste (sewage) water is treated by the sewage system of the Science Park Management Bureau, to be in compliance with the discharge standards of waste (sewage) water in the sewers to ensure the waste and polluted water reaches local environmental discharge standards. This facilitates that subsequent treatment of water quality reaches the standards for discharge into streams.
