Abstract：
The aim of this project is to understand the usage and emission of fluorinated GHGs in Taichung County (including the Central Taiwan Science Park). The first stage of the project is to collect information related to emission reduction strategies from various countries as well as data related to the usage of fluorinated GHGs (PFCs and SF6) by domestic industries (including semiconductor, LCD, electricity, and aluminum manufacturing). The next stage is to compile and to derive equations for the fluorinated GHGs emission factors for all the domestic industries. Results of the project can be divided and described in the following four areas:
(一) Collected information related to PFCs and SF6 emission reduction strategies, measures, and relevant technologies from domestic as well as oversea industries.
Information were collected from the following sources: periodicals for fluorinated GHGs, information networks related to reduction and regulation, the information network of Facing Global Warming–Taiwan’s Response, information networks for industrial GHGs, competent authorities worldwide for atmosphere protection, international organizations for atmosphere protection, relevant websites from the United Nation (browsed regularly), websites for environmental and atmosphere protection from E.U., U.S.A., Japan, and other advanced countries, and domestic as well as international publications and journals related to industrial PFCs and SF6. The target information were: the most updated information from all industries related to international regulation development, replacement technologies, PFCs and SF6 research overseas and domestically, as well as application of the most recent strategies, techniques and relevant technologies for PFCs and SF6 emission reduction. Techniques for treatment that are appropriate and feasible domestically shall be evaluated to provide a reference for relevant industries in Taichung County.
(二) Conducted interviews to investigate the usage and emission of fluorinated GHGs among relevant industries in Taichung County. Two experts or scholars were invited for coaching and conducting the investigation.
Investigation on the usage and on-site coaching for improvements for three private or public sites related to the industries in semiconductor, photo-electronics, and electricity were completed. Moreover, appointed experts had provided on-site coaching to improve the usage and emission of fluorinated GHGs. They also analyzed the status of fluorinated GHGs usage and emission in Taichung County and its environmental impacts.
(三) Coached and evaluated the production process of PFCs and SF6 by relevant industries in Taichung County, and estimated the emission of PFCs and SF6
The investigation on the total fluorinated GHGs emission by the industrial manufacturing sector (including semiconductor, photo-electronics, and electricity) in Taichung County in 2008 was completed. The total fluorinated GHGs emission was 201721.858 tonnes of CO2 equivalent, in which the total PFCs emission was 177886.442 tonnes of CO2 equivalent (8.48% of the entire nation), the total SF6 emission was 17564.094 tonnes of CO2 equivalent (0.40% of the entire nation), and the total HFCs emission was 6271.322 tonnes of CO2 equivalent (4.01% of the entire nation).
It was found from four on-site outcome interviews that all those four public or private factories in this project had purchased the destruct-controlling or recycling facilities. Also, the implementation of GHGs self-examination and volunteered reduction operation in those factories had been successful.
(四) Promoted and educated fluorinated GHGs emission reduction.
The 2009 reduction technique workshop was hold on June 23, 2010. The target group for this workshop was personnel involved in medium and small enterprises (including semiconductor, photo-electronics, electricity, and aluminum manufacturing industries) in Taichung County. Two issues were discussed in this workshop. First, Research fellow from the Energy and Environment Research Laboratories of Industrial Technology Research Institute was invited to present the fluorinated GHGs management strategies promoted by the Environmental Protection Administration. Then, Assistant Research Fellow, who is also from the Energy and Environment Research Laboratories of Industrial Technology Research Institute, presented the outcomes from the earlier stage of reduction implementation in photo-electronics and semiconductor industries. PFCs and SF6 emission reduction techniques (e.g., chemical replacement, manufacturing upgrade, recycle and reuse, end-of-pipe control, etc.) were discussed in the workshop as well.
(五) Established the fluorinated GHGs emission factor for the technological industry.
This project had estimated the emission and the emission factor for the technology industry in Taichung County. The emission factor in this project is a product-based estimation, and the unit is “tonne-emission/tonne-product” or “tonne-emission/thousand-slice-utput”. The factor issued by the Environmental Protection Administration, on the other hand, was material-based, and the unit was “tonne-emission/tonne-input.”
The factor estimated by this project and the one issued by the Environmental Protective Administration are based on different activity intensity (the former is product-based and the latter is material-based), but the references and assumptions for calculating the factor are both according to the guideline issued by IPCC. Therefore, the emission factor obtained in this project can be used by business and administrative agencies as a reference for various conditions (e.g., estimation for the usage of the front-end materials or for the back-end production capacity).
