摘要

摘要 廚餘在農業時代起一直都作為牲畜糧食再利用，加上台灣的養豬業
的興盛，廚餘再利用去化場所多數為養豬場，2018 年因受非洲豬瘟
1. 前言
影響，各縣市禁止廚餘餵豬，使得廚餘去化成為棘手問題。依據廢
2. 文獻回顧 資課統計資料，台積公司一年廚餘約為 1600 噸，每天廚餘量約為
4.5~5 噸，數量實為不少。考量未來廚餘去化風險，經多方評估，
2.1 有機質做為肥料的原因
採用高效廚餘堆肥技術將廚餘轉化為有機肥料。2020 年於中科導入
2.2 堆肥化原理
快速發酵機，經歷一年試驗與運轉，可將廚餘發酵時間由傳統一個
2.3 堆肥反應影響因子 月縮短為 7 天，2022 進一步將發酵時間縮短為 3 天，肥料品質符
合農委會雜項堆肥標準。廚餘轉化為肥料比例約為 20~30%，預估
3. 研究方法
全公司廚餘將轉化為肥料，每年產出 400 噸有機質肥料。
3.1 成分分析
關鍵詞 : 廚餘、快速堆肥、肥效
3.2 種子發芽率試驗
3.3 植栽生長試驗 In the era of agriculture, kitchen waste has always been
reused as livestock feed. With the prosperity of Taiwan�s pig
4. 結果與分析 farming industry, most of the places reusing kitchen waste are
pig farms. In 2018, due to the impact of African swine fever,
4.1 成分分析
all counties and cities banned the feeding of kitchen waste to
4.2 種子發芽率試驗 pigs, making the issue of kitchen waste disposal a challenging
problem. According to statistics from the Waste Resource
4.3 植栽生長試驗
Department, Taiwan Semiconductor Manufacturing Company
5. 結論與未來展望 produces about 1600 tons of kitchen waste per year, with a
daily amount of 4.5 to 5 tons, which is quite substantial. After
參考文獻 weighing several factors and considering the future risks of
kitchen waste disposal, it was decided to utilize effective
作者介紹
kitchen waste composting technology to convert kitchen
waste into organic fertilizer. In 2020, a fast fermentation
machine was introduced at the Hsinchu Science Park. After a
year of testing and operation, it can reduce the fermentation
time of kitchen waste from a traditional month to 7 days. By
2022, the fermentation time was further reduced to 3 days.
The quality of the fertilizer complies with the miscellaneous
compost standards of the Agriculture Commission. The
proportion of kitchen waste converted into fertilizer is about
20 to 30%. It is estimated that all the company�s kitchen waste
will be converted into fertilizer, producing 400 tons of organic
fertilizer per year.
