Site-specific dataset of mining and metallurgical residues for resource management.

This geospatial dataset provides a compilation of findings from an evidence-based review of site-specific resource assessments of mining and metallurgical residues. Information pertaining to location, target material, geological knowledge, extractability, resource classification and stakeholder perspectives was collected from publicly available reports, articles, academic theses, and databases. The dataset includes 44 relevant data attributes from 64 mining and metallurgical sites in 27 countries.

Data description of "building age map, Vienna, around 1920".

Building age maps inventory the construction dates of buildings. While many cities routinely map the construction dates of present building stocks, building age maps of the distant past are mostly not available. An exception is the building age map of Vienna around 1920.

Data description of "City boundary and urban district boundaries, Vienna, 1920".

This article presents geospatial datasets for administrative boundaries of the city of Vienna in 1920. One dataset covers the city area and another the urban districts. The boundaries were retrieved from historic analog maps that show the course of the borders at this time.

Building schematic of Vienna in the late 1920s.

Urban archives provide rich information on historical data. To a large extent, these data are not available in machine-readable format and therefore not linkable with other datasets. The "Häuser-Kataster der Bundeshauptstadt Wien" is a building schematic for the city of Vienna for the end of the 1920s.

Taking Stock of Built Environment Stock Studies: Progress and Prospects.

Built environment stocks (buildings and infrastructures) play multiple roles in our socio-economic metabolism: they serve as the backbone of modern societies and human well-being, drive the material cycles throughout the economy, entail temporal and spatial lock-ins on energy use and emissions, and represent an extensive reservoir of secondary materials. This review aims at providing a comprehensive and critical review of the state of the art, progress, and prospects of built environment stocks research which has boomed in the past decades. We included 249 publications published from 1985 to 2018, conducted a bibliometric analysis, and assessed the studies by key characteristics including typology of stocks (status of stock and end-use category), type of measurement (object and unit), spatial boundary and level of resolution, and temporal scope.

The Copper Balance of Cities: Exploratory Insights into a European and an Asian City.

Material management faces a dual challenge: on the one hand satisfying large and increasing demands for goods and on the other hand accommodating wastes and emissions in sinks. Hence, the characterization of material flows and stocks is relevant for both improving resource efficiency and environmental protection. This article focuses on the urban scale, a dimension rarely investigated in past metal flow studies.

Sinks as limited resources? A new indicator for evaluating anthropogenic material flows.

Besides recyclables, the use of materials inevitably yields non-recyclable materials such as emissions and wastes for disposal. These flows must be directed to sinks in a way that no adverse effects arise for humans and the environment. The objective of this paper is to present a new indicator for the assessment of substance flows to sinks on a regional scale.

Sustainable resource use requires "clean cycles" and safe "final sinks".

In order to fulfill the objectives of environmental protection, today's focus on quantitative recycling rates must be amended by a more qualitative approach. Because modern products represent a mix of numerous and sometimes hazardous substances, ways must be explored to remove detrimental substances during recycling and to establish "clean cycles". On the one hand, such a "clean cycle" strategy will result in better recycling qualities of secondary products and less dissipation of hazardous substances during further product use.
