Waste Management

To fulfill the sustainable government goals of being friendly to the environment, in addition to arranging professional technology personnel in accordance with Article 28-2 of the Waste Clearance Act, TTY also aggressively trains dedicated personnel. In year 2022, TTY had a total of 5 dedicated waste professional personnel (2 in the Lioudu factory, 2 in the Chungli factory, and 1 in the Neihu factory) and submitted a waste clearance plan pursuant to the law for operation with the approval of the agency designated by the municipality, county (city) competent authority, or central competent authority. TTY also signs contracts with qualified clearance and processing institutions to clear and process business and daily waste pursuant to the law. In addition, the Management of Waste Clearance and Tracing Regulations are based on Article 14-2 of the Permit Management Regulations for Public and Private Waste Clearance and Disposal Organizations. All clearance machines and devices of waste contractors need to be declared and approval. Meanwhile, all vehicles delivering TTY’s business waste must be equipped with GPS, and the vehicle trace return rate must reach 90% to facilitate real-time monitoring of the competent authority and TTY.
To fully understand waste flow of factories and reinforce supplier audits, in addition to checking orders every week and tracking disposal vehicle GPS abnormalities, TTY also follows supplier handling conditions every month and conducts on-site audits every year to confirm the output and flow after processing. Moreover, TTY implements irregular vehicle audits to confirm that waste disposal and handling contractors do business pursuant to laws. In year 2022, the total waste of TTY in the Lioudu, Chungli, and Neihu factories was about 49.73 tons, from among which hazardous waste was 28.55 tons and non-hazardous waste was 21.18 tons. All such waste was delivered to qualified disposal contractors for off-site treatment. The Chungli and Lioudu factories achieved 100% in weekly and monthly audits without a violation of the Waste Clearance Act or other relevant laws, or causing impact to the local environment. Meanwhile, the Neihu factory expects and arranges to complete at one on-site audit in year 2023.

Waste Directly Disposed According to Disposition Operations in the Recent 5 Years (unit: Tons)

As per the Energy Bureau, 97.7% of energy in year 2021 was imported. To reduce reliance on imported energy, and maximizing the energy efficiency as promoted by the EPA, in year 2022, TTY Lioudu factory took the initiative to gather all flammable waste with the help of the waste treatment plant to fully combust, used a steam boiler to collect the steam from the combustion process, then turned the heat into power through a steam turbine. This approach has reduced the waste volume of the Lioudu factory as we extract energy from waste. We not only saw a good amount of recyclable energy this year, but hazardous waste volume dropped significantly from year 2021.
