Waste management

Waste transportation and entry management

ECOVE Waste Management Corp. is responsible for waste collection, transportation, disposal, incineration residue management, and related services. In 2022, the total amount of waste managed by the Company was 287,251 metric tons, accounting for 35% of the total waste entrusted to private organizations for management at large-scale urban waste resource recycle (incineration) plants in the country. To effectively manage waste quality, ECOVE Waste Management Corp. utilizes an intelligent management system that screens vendor qualifications, approves waste types, establishes and stores entry data, and performs real-time monitoring of entry information. Through the analysis of entry statistics, waste quality is effectively controlled. In 2022, the management system was further optimized by adding functionality to interface with the declaration system of the Environmental Protection Administration. This allows for the rapid and accurate upload of data to the regulatory center, ensuring legal compliance and reducing redundant work. Additionally, the management system provides real-time updates and announcements on environmental regulations and entry management information for vendors. It establishes lists of inappropriate waste or vendors in each incineration plant to enhance regulatory efficiency and analyzes waste characteristics in different regions to achieve effective resource management.

To further understand and confirm the sources and nature of the waste, on-site visits and guidance were conducted for waste generators. In 2022, a total of 116 visits were conducted to gain insights into their processes, waste generation quantities, storage conditions, and other relevant information. During these visits, relevant environmental regulations were explained, and key management points for the entry and exit of waste at incineration plants were highlighted. Suggestions were also provided to optimize waste management practices. These efforts ensure that the waste provided by waste generators meets the operational requirements of the incineration plants, ensuring stable processing efficiency and minimizing processing risks. Furthermore, waste generators are guided to explore resource recovery options for waste that would otherwise be misplaced in incinerators. For example, assistance is provided in connecting waste generators with Solid Recovered Fuel (SRF) manufacturing plants. Currently, there are ongoing connections with SRF manufacturing plants such as Lien Tai Paper Co., Ltd., and Green Pine Environmental Protection, aiming to achieve sustainable operations.

In the field of waste incineration, as part of our long-term waste reduction goals, we aim to facilitate the recycling and disposal of sludge generated from agriculture, forestry, fisheries, and manufacturing industries through resource circulation. Our target is toreduce the incoming volume by 50% compared to the base year of 2018. In 2022, the amount of sludge received was 2,190 tons, achieving a reduction of approximately 65% and successfully meeting the target. We will continue to maintain this incoming volume of sludge in the future.

Waste incineration volume

ECOVE Environment Service Corp.'s main business operation is waste incineration, converting thermal energy into electrical energy and reselling it to power companies as one of Taiwan's power sources. In addition to reducing the use of fossil fuels, it also mitigates the pollution impact from landfilling waste. Through ECOVE Environment Service Corp.'s optimal operational techniques, not only is maximum power generation efficiency achieved from the incineration of waste, but also the energy and efficiency required during the waste disposal process are greatly maximized. This helps reduce waste, emissions, wastewater, and secondary pollutants, fulfilling the mission of "optimizing resource circulation efficiency.

ECOVE Environment Service Corp. currently manages eight large-scale waste incineration plants and two small-scale industrial waste incineration plants. For the purpose of analysis, the data presented here focuses on the eight large-scale incineration plants ❶ , including the Keelung Plant, Southern Taoyuan Plant, Miaoli Plant, Houli Plant, Wujih Plant, Xizhou Plant, Chengxi Plant, and Gangshan Plant. In 2022, the total amount of waste received by the plants (general waste and general industrial waste) was 2,095,875.65 metric tons. Considering the total waste received by all 24 waste incineration plants in Taiwan in 2022, which was 6,201,993.09 metric tons, ECOVE Environment Service Corp. accounted for 33.8% of the total. Among them, general waste accounted for 1,703,308.39 metric tons, representing 81.27% of ECOVE Environment Service Corp.'s total intake, while general industrial waste accounted for 392,567.26 metric tons, representing 18.73% of ECOVE ESC's total intake.

According to the latest announcement by the Environmental Protection Administration,Executive Yuan, Taiwan generates an average of approximately 1.152 kilograms of waste per person per day ❷ . Incineration accounts for 41.23% of waste treatment, which means ECOVE Environment Service Corp. serves an equivalent of around 9.824 million people's annual waste generation. Hazardous industrial waste, as regulated by laws and regulations, must be handled by specialized treatment facilities, and the incineration plants operated by our company do not accept hazardous waste.

In addition to Taiwan, our waste incineration services have also expanded overseas, with our subsidiary SINOGAL undertaking general waste disposal business in the Macau region. With a local population of approximately 830,000 people, the total intake of waste in 2022 was 505,971 metric tons, of which general waste accounted for 347,343 metric tons, representing 68.65% of the total, and general industrial waste accounted for 158,628 metric tons, representing 31.35% of the total. Based on the average of the past four years, the annual average total intake was 526,463 metric tons, and the average total processing quantity was 525,467 metric tons.
