目前在台灣的科技新製程在毒化物原料使用上，常忽略產品生命週期評估的環境考量，本研究係利用生命週期評估的概念與依據「行政院環境保護審核毒化物質使用於新目的用途作業要點」之規定，分析石化原料1,3-丁二烯運用在科技產品硬碟片(HDD)的原製程(使用前)新製程(使用後)之生命週期評估的方法作為環境衝擊的影響評估，並利用Simapro7、工研院研發DoItPro資料庫分析軟體及Eco-Indicator95生命週期評估指標架構以了解1,3-丁二烯原料在科技產業使用上對潛在環境衝擊影響的程度。
本研究乃以CNS14040生命週期評估系統系列標準之規範程序，搜集生產活動6個月的數據資料並整理相關的資料外，再利用Boustead Model、SimaPro7、EcoPro、Gibi等電腦資料庫參考及套用，並利用Eco-Indicator95環境指標架構完成初步盤查項目的生命週期環境衝擊評估分析，得到各項目衝擊評估的關切點;再以丁二烯原料投入生產到成品製程的流佈，用儀器分析檢測以合理的數據及假設來完成丁二烯原料在新製程的生命週期評估，並以新、舊製程上分析比較可以得到產品衝擊評估關切點，在使用階段溫室效應的氣體排放及資能源的影響效應，比較分析結果提供科技產業評估產品環境化設計及永續經營的參考。

At present in Taiwan''s technical newly process in the poisoning raw material use, Often neglects the product life cycle assessment the environment consideration,This research is the concept and the basis which appraised using the life cycle "the Executive Yuan environmental protection verification poisoning matter use to the new goal use work main point" the stipulation, Analysis pertrochemical material 1,3- butadiene utilization after technical product hard disk (HDD) the original system process (before use) the newly process(use) the life cycle assessment the method appraised as the environment impact influence that, and appraised the target overhead construction understood 1,3- butadiene(C4H6) material attacks the influence in the technical industry use to the latent environment the degree.
This research standard of procedure by the CNS14040 life cycle assessement systematic series standard, outside the collection production activity data for six mouth of material and the reorganization related information bank will use again Boustead Model、SimaPro7、EcoPro、Gibi ,The computer information bank applies mechanically, and completes the preliminary questioning goal life cycle environment impact assessment analysis, obtains various projects impact assess the pass; Again produces the class step by the 1,3- butadiene(C4H6) material investment which makes to the end product, completes the 1,3- butadiene material with the instrumental analysis examination by the reasonable data and the supposition to appraise in the newly process life cycle, and by is new, the old system process in analyzes the comparison to be allowed to obtain the product impact appraisal to close the tangential point, Discharges and the capital energy
influence effect in the operational phase greenhouse effect gas, the comparative analysis result provides the technical industry to assess the product environment design and continues forever the management the reference.
