Note: 1.All waste is outsourced for removal and treatment. Direct disposal methods include incineration, while transfer disposal methods involve selling scrap to recycling companies. In 2022, calculations were based on an outsourced transportation contract averaging 73 tons/month * 12 months. In 2023, calculations were based on actual entry records from the incineration plant, leading to differences in total amounts over the two years. 2. Number of scrapped computer hosts: 271 units, average weight per unit: 7.3 kg, 271 * 7.3 = 1,978 kg = 1.978 metric tons 3. Number of scrapped computer monitors: 111 units, average weight per unit: 3.9 kg, 111 * 3.9 = 433 kg = 0.433 metric tons 4. Number of scrapped printers: 100 units, average weight per unit: 6 kg, 100 * 6 = 600 kg = 0.6 metric tons |

Note: 1. All waste disposal is handled by an outsourced contractor, with incineration used for direct disposal and scrap sales to recycling vendors for transfer disposal. Based on the outsourcing contract, an average of 73 tons per month is calculated over 12 months. 2. The number of discarded computer hosts is 826 units, with an average weight of 7.3 kg per unit, 826 * 7.3 = 6,030 kg = 6.03 tons 3. The number of discarded computer monitors is 519 units, with an average weight of 3.9 kg per unit, 519 * 3.9 = 2,024 kg = 2.02 tons 4. The number of discarded printers is 182 units, with an average weight of 9.5 kg per unit, 182 * 9.5 = 1,729 kg = 1.7 tons |
