“…Although extraction data are similar across global databases with regard to categories such as agricultural production or extraction of fossil fuels (Fischer-Kowalski et al 2011), estimations need to be applied for quantitatively important categories, such as construction materials (see above and Additional file 3 for details). This calls for further international efforts to align existing estimation approaches, including the consideration of recycled construction materials (Hashimoto et al 2009;Wiedenhofer et al 2015).…”

In the context of the transformation toward a "green economy, " issues related to natural resource use have rapidly increased in importance in European and international policy debates. The large number of studies applying economy-wide material flow analysis so far mostly produced aggregated national indicators, making the results difficult to connect to policies, which are often designed for single sectors or consumption areas. This paper provides a detailed assessment of the composition of EU's material footprint in its global context, aiming at identifying the main product groups contributing to overall material consumption and specifying the geographical sources for the raw materials required to satisfy EU's final demand. Based on multi-regional input-output (MRIO) modeling, we apply production layer decomposition to assess supply chains and their structural changes from 1995 to 2011. The global MRIO database used in this study is EXIOBASE 3, which disaggregates 200 products and 163 industries, of which 33 represent material extraction sectors. By that means, we increase the level of detail to a degree where policies can more easily connect to. We find that the generally growing material footprint of the EU was characterized by a dramatic shift regarding the origin of raw materials, with the share of materials extracted within the EU territory falling from 68 % in 1995 to 35 % in 2011. In 2011, raw materials extracted in China to produce exports to the EU already contributed an equal share to EU's material footprint as material extraction within the EU itself. Import dependency is most critical for the material group of metal ores, with only 13 % of all metals required as inputs to EU final demand stemming from within the EU. Regarding product composition, construction was confirmed as the most important sector contributing to the material footprint, followed by the group of manufacturing products based on biomass. Materials embodied in service sector activities together contributed a quarter to the total material footprint in 2011, making services an important, but currently disregarded area for European resource policies. We also find that supply chain structures became more complex over time, with a growing part located outside the EU territory.

1280In the current study, how planning and truck-mixer based waste amounts per 1 m 3 fresh ready-mixed concrete (RMC) can be determined was presented. Toward this aim, the formation process of the fresh RMC waste in construction projects was first introduced in a detailed manner, together with an in-depth literature review in this specific domain of the construction engineering and management. Then, the measurement procedure of the waste amount or coefficient of the fresh RMC was revealed and discussed as a practical and creative planning knowledge. Hence, a useful and realistic waste management perspective about the cost and potential environmental savings of the RMC waste was drawn. Fresh Ready-Mixed Concrete Waste in Construction Projects IntroductionConstruction wastes not only affect the economy of a country, but also consume natural resources and pollute the environment for a very long term. According to Garvin (2004), 40-50% of the energy produced in the world and 16% of available water resources are consumed to produce construction materials defined as waste. CO2 that appears in the production process of such materials makes up 50% of the total CO2 emission in construction. Given the transportation of these material wastes, this share of 50% likely reaches up to 75%. In this environmental pollution and resource consumption, it should be noted that the cement manufacture plays an important role. In addition, construction wastes occupy large areas by volume. They have a share of approximately 20-40% of the total area occupied by wastes in the US, Canada, Hong Kong, Australia, Japan, and European Union countries (Stokoe, Kwong & Lau, 1999;Kibert, 2000;Poon, 2007). This share can likely increase further if wastes are measured in weight (Mulheron, 1988;Hendriks & Pietersen, 2000). Today, the construction industry tries to deal with enormous amounts of wastes as they are very damaging to the environment. However, it is very hard to assert that the construction industry has generally constituted and improved its waste-based business culture so far. In order to reveal the current position of the construction industry as a whole in terms of types and amounts of construction wastes, it is inevitable that various types of estimates and plans on sub-sectors of the construction industry should be carried out.In this context, how planning and truck-mixer based waste amounts per 1 m 3 fresh ready-mixed concrete (RMC) can be determined was presented in the current paper as a part of an on-going research project. This is because, in a reinforced-concrete building project, concrete can have a big share of about 10% of the total project budget (Kazaz, Ulubeyli & Turker, 2004). Of course, these amounts can be single numbers or interval-based values. This decision can be based on a statistical analysis of the real world data. Thus, while preparing their proposals, construction contractors in general and quantity surveyors and cost managers in particular can better estimate the amount and cost of RMC by means of these numeri...

“…While a review of the literature shows that most studies examine either only specific resources or input and output material flows on a national level. (e.g., [12,14,23,26,28,31,35,36,48,49]), Kleemann et al [41] and Schneider et al [13], examine the material flow in the building sector on the city level (Vienna and Zurich, respectively). The present study examines material quantities for a typical urban area in Germany.…”

Creating a Resource Cadaster—A Case Study of a District in the Rhine-Ruhr Metropolitan Area

Today, both resource efficiency in general and the efficient use of natural resources specifically in the building sector are major political issues. Recent studies on resource efficiency have found the "anthropogenic stock" of the building sector to outweigh natural resource stocks. To make the anthropogenic stock accessible, material quantities with their individual composition need to be estimated and extrapolated to regional level. A geographical information system (GIS) is used as tool to handle the building specific data and combine them on regional level to calculate the anthropogenic stock. The resulting resource cadaster reflects the material quantities, divided into sixteen material fractions, of a specific residential district in the Rhine-Ruhr metropolitan area-a typical urban area in Germany. The case study area was weighted in total between 103.5 kt and 93 kt, depending on the dataset. This paper offers a step-by-step description of this approach, whereby a consistent dataset was created throughout the process of data collection and validation. In order to demonstrate the broader application of the resource cadaster, the results were extrapolated to the residential building sector of the entire federal state of North Rhine-Westphalia. In highly concentrated areas, like the Rhine-Ruhr Metropolitan area, both area-wide classification of material quantities and their regional localization are necessary to make the anthropogenic stock accessible. Information about toxic substances, however, also needs to be included in the process of data collection. This method of mapping could thus provide the foundation for future (re)uses of this stock. This study offers some concrete steps in the direction of achieving a circular economy.
