There were four major tasks in this two-year project,
including:
(1) To strengthen the system for the management of incinerator
ash in incineration plants, and to promote the reuse of
incinerator ash
(2) To audit the disposal and reuse records of incinerator ash and
to provide the improvement guidance for the incineration
plants in order to reduce the environmental impact
(3) To enhance the source management of waste entering into
incineration plants and to improve the quality of products
made from incinerator ash
(4) To assist city and county governments in executing general
waste clearance, and to promote the proper management
Four major achievements of this project in year 2008 are
shown as below:
(一) Studied and amended relevant ash treatment and reuse
measures to promote the activities for incinerator ash reuse
This project compiled the quality, characteristics,
management, related regulations, and current implementation
status of the reuse of incinerator ash in Taiwan, and analyzed
relevant problems and countermeasures. Moreover, this
project assisted the Environmental Protection Administration
(EPA) in establishing a 3-step quality management system
(including the step 2: operation instructions and step 3:
inspection specification), building and continuously
upgrading and maintaining the On-line Declaration System of
Bottom Ash Reuse.
In the meantime, this project reviewed a certification
system suitable for recycled products of bottom ash in Taiwan
and analyzed the overall impact of adopting waste reuse
standard in foreign countries on domestic reuse of incinerator
ash. This project also carried out an overall analysis
covered fly ash recycling technology, economy, application,
promotion, strategy, and environment.
The bottom ash sample of No. 806 incineration plant had
been selected and tested, based on the Toxicity Characteristic
Leaching Procedure (TCLP) and the Waste Reuse Leaching
Procedure adopted in developed countries (California of
USA/European Union) respectively. According to the result of
the test, a feasibility study were further conducted to evaluate
the possibility to apply the waste reuse standard in foreign
countries for the incinerator ash reuse management in Taiwan.
(二) Carried out the auditing of incinerator ash clearance and reuse
in order to control the disposal of incinerator ash and provide
suggestions for improvement
From January to October 2008, the quantity of
incinerator ash and its disposal were posted through the
Internet. These reports were also cross-checked with the data
announced in the Solid Waste Incineration Management
System (SWIMS) and the Industrial Waste Management
System (IWMS) of the EPA to assure the quantity of
incinerator ash and its disposal were properly treated and
managed. Meanwhile, the Global Position System (GPS)
equipped on the vehicles conveying derivatives of fly ash and
bottom ash were also traced by the IWMS.
This project performed the site inspection of incineration
plants, mid-treatment (solidification) plants, bottom ash
landfills, and provided the improvement guidance to the
plants or factories involved in faulse reports. The monthly
reports of bottom ash reuse from January to October 2008
were checked. This project also provided site inspections
and improvement comments to four bottom ash reuse agencies
(Guobin, Yinchen, Cyuanjingying, and Yongsheng) on their
operations and the disposal of reuse products.
In addition, this project sampled the ash (bottom ash and
derivatives of fly ash) of No. 806 incineration plant to test
quantity and density of heavy metal leaching and dioxin
contents.
(三) Studied control measures on wastes entering into incineration
plants to enhance the quality of recycling products of
incinerator ashThis project collected the review and assessment results
from the Environmental Protection Administration and the
newest draft of controlling wastes entering into incineration
plants, studied the ideas of using portable XRF analyzer in
waste check, and provided control measures and applied the
measures in the incineration plant in Keelung City.
Besides, this project analyzed the impact on the quality
of incinerator ash caused by operations condition of
incineration plants and prepared suitable proposals of
practical promotion methods for the operation of incineration
plants.
(四) Assisted in the execution and management of landfills, bottom
ash, and septic waste treatment works
This project has assisted the EPA in the following
activities for county and city governments:
Investigation and control of current status on the proper
operations and management of landfills for general waste
Monitoring of the execution status and promotion
effectiveness of septic waste treatment
Provision of professional opinion and administration
works to their incineration ash reuse plants and monitoring
of their execution status
Meanwhile, one review meeting of reuse of incinerator
ash was held on Nov. 4, 2008 and attended by city and county
environmental protection bureaus and bottom ash reuse
agencies to review the present management regulations.
Suggestions were provide as the reference for the amendment
in the future.
