The purpose of this project is mainly to conduct quality inspection, flow direction control, inspection supervision and environmental monitoring of the incinerating recycled aggregate to ensure that the incinerating recycled aggregate can be reused without any risk to the environment. The final report of work completion includes:
1. The returned incinerating recycled aggregate were sampled and tested 12 points, and the "Environmental Use Leaching Procedure for Recycled Aggregates (NIEA R222.11C)" was used for testing and analysis. The test results at 10 points met the first and second level standards of the regulations；Among them, mercury, cadmium, and arsenic were not detected, and nickel, copper, chromium, zinc, and dioxin were detected in trace amounts. The test results showed that lead exceeded the standard at 2 points. The manufacturer has been notified to prohibit use of the batch of incinerating recycled aggregate and the batch will be transported back to the warehouse for temporary storage until the extended aging period for re-testing. After re-testing in January 2024, it has passed the regulatory standards. Soil and groundwater were tested for 5 points each, for a total of 10 points. The 5-point soil test was in compliance with regulatory standards, while the groundwater was sampled and tested for 5 points. The sampling test results showed that chromium, cadmium and lead were not detected at all points; copper, zinc, nickel and mercury were detected in trace amounts, which did not exceed the Type II monitoring standards. Ammoniacal nitrogen was detected at 1 point, iron was detected at 1 point and manganese was detected at 4 points exceeded the Type II monitoring standards.
2. Inspection of the incinerating recycled aggregate reuse treatment plant, including its usage and temporary storage location, with a total of 187 inspections, its reuse treatment plant was muddy due to the washing equipment; temporary storage locations and processing and remanufacturing locations must pay attention to the operation and maintenance of pollution prevention and control equipment to avoid secondary pollution; no abnormal conditions were found in the project usage site, which complied with the regulations, and no violations occurred. Through inspection operations, the proper use of bottom ash treatment and incinerating recycled aggregate can be effectively monitored. From the start of the project to February 29, 2024, a total of 49 applications have been applied for the use of incinerating recycled aggregate.
3. Completion of the incinerating recycled aggregate business-related observation activities, with 51 participants which meets the standard number of participants; incinerating recycled aggregate promotion, resource recycling and environmental protection facilities and other related business observation activities, the number of participants reached 15 persons has been in line with the number of norms.
4. Completed the Drone Professional Operator's Certificate (POC) subject test for 8 persons and completed surgical training for 8 persons. The technical test has been scheduled for March 18, 2024.
5. Assisted RETRIEVE ENTERPRISE CO., LTD. in the county to apply for the green mark of cubic bricks, and the document review has been approved.
6. On August 28, 2023, a meeting of the incinerating recycled aggregate supervision and promotion group was held, which chaired by Environmental Protection Bureau Secretary Chang Qiao Wei, in which the Public Works Department of the Yunlin County Government, the Water Conservancy Department, and the municipal offices of various townships were requested to take stock of their respective demand for the first- and second-level standard materials in 2024, so that the Environmental Protection Bureau can plan and distribute transportation in advance; an incinerating recycled aggregate presentation was held on September 25, 2023, in which the Chief of the Transportation and Construction Section of the Public Works Department was invited to explain the application of recycled aggregate in the county, and sharing their experiences of the exchanges between the Yunlin County Government and recycling plant in Singapore.
