Waste Management

In 2021, we generated a total 194.26 tons of waste, including general industrial waste and domestic waste (excluding class E hazardous industrial waste), in which 47.39 tons (24.40%) of the waste were recycled, while 146.87 tons of waste could not be recycled. Total waste generation in 2021 decreased by 34.66 tons from last year. This is due to the reduction in the generation of domestic waste because the Company implemented work-from-home and working staggered shifts for three months in response to the pandemic. The waste generation intensity was 0.0031 tons per million NTDs of operating revenue in 2021, down by 35.75% from the previous year.

Amount of Waste Generated in 2021

Hazardous Industrial Waste

Hazardous industrial waste is the waste generated by any business that is toxic, dangerous, and in sufficient concentration or quantity to affect human health or pollute the environment. Phison generates hazardous industrial waste, mainly under the waste item E0217 (Scrapped electronic parts and components, leftover scrap and defective goods) from our activities of product experimentation. In 2021, a total of 1.82 tons of hazardous industrial waste was produced by all of our operating sites in Taiwan; and all the waste has been completely removed at the end of 2021.
Phison has engaged qualified disposal and treatment vendors for the disposal of our hazardous industrial waste. A waste disposal and treatment agreement is entered into by and between our Procurement Department and any of such vendor. The Procurement Department will notify the contracted vendor to come into our facilities and remove the waste on a regular basis or when a certain amount of waste has been accumulated in our storage sites. The Environmental, Health and Safety Department will document the details of such removal in the "Industrial Waste Removal Record Sheet" and retain the record for a period of three years. To ensure our hazardous industrial waste is handled properly by our contracted disposal and treatment vendors, the Environmental, Health and Safety Department will inspect the operating procedures of the disposal and treatment vendors and their operating performance on a regular basis by following the removal truck to its destination in person or conducting on-site audits, making sure that the risks and impacts of our hazardous industrial waste posed on the environment are minimized.
