“…While understanding of peace-time recycling is well established, and several models exist (Hsiao et al, 2002;Blengini, 2009), the effect of large quantities of specific debris types is not understood. Factors such as: the effect of surplus materials on existing recycling markets; the need for establishment of post-disaster markets (eg.…”

Taking Stock of Industrial Ecology

Material fl ow analysis (MFA, also known as Material Flow Accounting) has become one of the basic tools in industrial ecology, since its pioneering development by Ayres. This chapter reviews progress in MFA with emphasis on the use of MFA to support waste management and recycling policy.Waste statistics are compiled in most developed and some developing countries, but the basis is insuffi ciently standardized so that care is needed in making comparisons between countries. This also applies to recycling fl ows, which are diffi cult to defi ne and quantify. Waste arising from demolition can be predicted by dynamic modeling which also predicts future resource demand, but the discrepancies between predicted and reported waste quantities can be large due to "missing" or "dissipated" stock. Metals represent an important and valuable component of waste; metals in endof-life vehicles and e-waste in particular need to be quantifi ed for their recycling and ecological and human health impact assessment. MFA has also been applied to international trade of secondhand products containing metals. MFA studies on phosphorus have revealed potential ways to increase recovery that go beyond recycling from obvious wastes.

“…When looking at them at the country level, it is observed that different countries around the world have been investigated in this regard. Among them, there are (i) European countries such as Netherlands (Bossink & Brouwers, 1996), Greece (Banias, Achillas, Vlachokostas, Moussiopoulos & Papaioannou, 2011), Norway (Bergsdal, Bohne & Brattebo, 2007), Ireland (Kelly & Hanahoe, 2008) (Coelho & de Brito, 2011a,b;De Melo, Goncalves & Martins, 2011;Malia, de Brito, Pinheiro & Bravo, 2013), and Germany (Hoglmeier, Weber-Blaschke & Richter, 2013), (ii) Asian countries such as Hong Kong (Tam, 2008;Jaillon, Poon & Chiang, 2009;Cheng & Ma, 2013;Li & Zhang, 2013), Taiwan (Hsiao, Huang, Yu & Wernick, 2002), Malaysia (Begum, Siwar, Pereira & Jaafar, 2006;Lau, Whyte & Law, 2008;Che Hasan, Yusof, Mohd Ridzuan, Atan, Noordin & Abdul Ghani, 2013;Nagapan, Rahman, Asmi & Adnan, 2013), China (Li, Ding, Mi & Wang, 2013), Japan (Hashimoto, Tanikawa & Moriguchi, 2009), and Thailand (Kofoworola & Gheewala, 2009), (iii) American countries such as the US (Cochran & Townsend, 2010), Canada (Wimalasena, Ruwanpura & Hettiaratchi, 2010), and Brazil (Formoso, Soibelman, De Cesare & Isatto, 2002), (iv) Middle Eastern countries such as Kuwait (Kartam, Al-Mutairi, Al-Ghusain & Al-Humoud, 2004), Palestine (Al-Sari, Al-Khatib, Avraamides & Fatta-Kassinos, 2012), Israel (Katz & Baum, 2011), and Lebanon (Tamraz, Srour & Chehab, 2011), and lastly (v) Australia (McDonald & Smithers, 1998).…”

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...
