Resulting shortages in the domestic supply of construction aggregates have forced the Republic of China (R.O.C.) government to attend to protect minable reserves from stealing unlawfully. To guide this activity, material flows analysis (MFA), which is based on the Industrial Ecology (IE) model, which advocates a systematic source view and industrial material sinks, as well as the web of economic enterprises that influence their flows through the economy, is proposed herein. This study was conducted to show the deposits, domestic supply, demand, per capita and per unit area demand of construction aggregates, total construction aggregates requirements (TAR), import, export, intensity (IU) and efficiency (EU) of use for construction aggregates in Taiwan.application/pdf184708 bytesapplication/pdfzh-TW國立臺灣大學環境工程學研究所砂石骨材永續發展工業生態 學物質流分析Construction aggregatesSustainable developmentIndustrial ecology (IE)Material flows analysis (MFA)reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/22098/1/902621Z002024.pdf
