“…The attributes of buildings in Taipei that were derived by HMFA are the same as described in Cheng et al. (), including the quantity of MS, building structure, use of building, age, and address. Thus the methodology of Cheng et al.…”

“…For the descriptions of Taipei City individual building construction data, refer to Cheng et al. () for details. In the top‐down approach, the DPO of Taipei City is the sum of construction wastes (Taipei City Government, ) and the construction residual soil (Ministry of the Interior, ).…”

“…In addition, MS is considered as a resource of the anthroposphere. The substances could be recycled in the SEM through urban mining, which is essential for society to become a circular economy (Cheng, Hsu, Li, & Ma, ; Koutamanis, van Reijn, & van Bueren, ; Zeng, Mathews, & Li, ). In recent decades, MS evaluation modeling approaches have been addressed and developed in several studies with a range of limitations (Augiseau & Barles, ; Chen & Graedel, ; Hashimoto, Tanikawa, & Moriguchi, ; Müller, Hilty, Widmer, Schluep, & Faulstich, ; Tanikawa & Hashimoto, ).…”

“…The quantity of MS in a system boundary can be calculated by multiplying all objects in the district with the material intensity (MI). This approach is widely used in MS evaluation at the micro‐level, providing information about a specific MS at high spatial resolution (Cheng et al., ; Kleemann, Lederer et al., ; Tanikawa et al., ), and even consolidating micro‐level MS to obtain the total amount of MS at macro‐level (Nguyen et al., ; Schiller et al., ). Nonetheless, the information needed for the bottom‐up approach would increase as the scale of investigation expands.…”

This study develops a hybrid material flow analysis (HMFA) method to evaluate the annual additional quantity of material stock, known as net additions to stock (NAS) at both micro‐ and macro‐levels through analyzing the fixed capital formation (FCF) and total supply in input‐output tables (IOTs). HMFA turns NAS from a balance indicator in the top‐down approach to an indicator with meaningful value in terms of urban ore evaluation. To verify the validity of HMFA, this study compares the developed HMFA with a top‐down approach and a bottom‐up approach through assessing the NAS of Taiwan and Germany. The quantity of NAS estimated by HMFA is considered as a more conservative upper bound than that by the top‐down approach, while underestimation often occurs with a bottom‐up approach. HMFA has been proven as an efficient and rational evaluation method which overcomes a key limitation in assessing micro‐level material stock by a top‐down approach, and solves the data demanding problem of the bottom‐up approach for quantifying material stock.
