Early Pregnancy in Times of Climate Change
OBJECTIVES: This study focused on the association between fetal crown-rump length (CRL) in the 12th/13th gestational week and the number of 1st trimester heat days to assess the impact of rising temperature on intrauterine growth in early pregnancy. METHODS: = 4857) taking place in Vienna, Austria between 2011 and 2019. The sonographic determination of CRL took place routinely during the 12th or 13th gestational week. Linear regression analyses w…
Understanding the evolution of cities through urban stocks
The evolution of cities follows distinct patterns that connect to the cultural and socioeconomic aspects of their populations and can be understood by studying their urban stocks. This paper examines the evolution of construction materials stocks (MS) in the building sector in five urban areas in Peru. The study employed a bottom‐up methodology and focused on the city of Abancay in the Peruvian Andes, comparing it to the coastal cities of Chiclay…
Material flow analysis and carbon footprint of water-packaging waste management
Packaged drinking water represents one of the fastest growing commodities on a global scale, and several alternatives to plastic have been proposed, such as glass, cardboard or aluminum. The research has a twofold goal: (i) first, it calculates the amount of water-packaging waste generated in Italy in 2020, distinguishing among PET, glass, aluminum and cardboard materials, and it applies the material flow analysis through the STAN 2.7.101 softwar…
Determining the material intensities of buildings selected by random sampling
Many studies calculate the material stock of buildings by using material intensities and reference values for building dimensions. Often, they lack a clear definition of and transparency in the selection of buildings to be analyzed, as well as adequate description for the determination of the material intensities of buildings. This article presents a randomized selection of buildings and determination of their material intensities using the case …
Material stock development of the transport sector in the city of Vienna
Societies aim to reduce primary raw material consumption, enhance waste recycling, and reduce waste disposal. In this regard, the circular‐economy concept has gained attention and is applied in policy papers, also on the urban level. However, to assess set targets and their achievement, a sound knowledge of anthropogenic material flows and stocks is required. The material turnover of transport systems has not been sufficiently investigated yet, a…
Extended ecological footprint for different modes of urban public transport
GIS‐based Analysis of Vienna's Material Stock in Buildings
The building stock is not only a huge consumer of resources (for its construction and operation), but also represents a significant source for the future supply of metallic and mineral resources. This article describes how material stocks in buildings and their spatial distribution can be analyzed on a city level. In particular, the building structure (buildings differentiated by construction period and utilization) of Vienna is analyzed by joini…
Present Potentials and Limitations of a Circular Economy with Respect to Primary Raw Material Demand
A Novel Approach to Characterize Data Uncertainty in Material Flow Analysis and its Application to Plastics Flows in Austria
Material flow analysis (MFA) is widely used to investigate flows and stocks of resources or pollutants in a defined system. Data availability to quantify material flows on a national or global level is often limited owing to data scarcity or lacking data. MFA input data are therefore considered inherently uncertain. In this work, an approach to characterize the uncertainty of MFA input data is presented and applied to a case study on plastics flo…
Prospecting and Exploring Anthropogenic Resource Deposits
Urban mining is seen as a key strategy for the recovery of secondary raw materials from the built environment. Although large material stocks have been reported in infrastructure networks, their actual recoverability over time has received little attention so far. This article presents a case study on the prospection and exploration of the anthropogenic resources deposited in Vienna's subway network. After quantifying the built‐in materials in th…
Historical iron and steel recovery in times of raw material shortage
Urban Mining in Times of Raw Material Shortage
The present article investigates to what extent and level of success urban mining—the recovery of resources from anthropogenic stock—has been applied in the past during shortages of primary resources. As a case study, the Austrian economy during World War I—when raw materials indeed had to be substituted from secondary sources—is analyzed here. By means of material flow analysis, the management of copper, an important and relatively scarce metal …
