In 2020, we generated a total 234.4 tons of waste, including general industrial waste and domestic waste, in which 49 tons (20.9%) of the waste were recycled and reused, while 185.4 tons of waste could not be recycled and reused. The significant decrease in our recycling rate compared to last year was mainly due to our initiative towards a paperless office, resulting a significant decrease in our recycled volume of paper. Furthermore, as a result of our continuous expansion of business operations and increase in our staff, waste generation in 2020 has increased by approximately 47.3 tons compared to last year, which converted to a waste intensity of 0.005 tons per million dollars of revenue, an increase of 12.77% compared to 2019.
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 2020, a count on the total weight of hazardous industrial waste produced by all of our operating sites in Taiwan was made for the first time, which was 0.95 tons in
total; and all the waste has been completely removed at the end of 2020.
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.
