“…Nickel (Ni(II)) and cadmium (Cd(II)) are toxic contaminants that can cause severe damage in human and aquatic life after being accumulated in high concentrations. Cadmium is commonly used in batteries, and coating and painting industries. − It is carcinogenic, causes iron deficiency, and accumulates in liver and kidney . Nickel comes out as pollutant from electroplating, metal finishing, and battery industry.…”

Carboxymethyl cellulose (CMC), microcrystalline cellulose (MCC), and xylan are cross-linked with β-cyclodextrin (βCD) using ethylene glycol diglycidyl ether cross-linker to produce hydrogels, namely, βCD-CMC, βCD-MCC, and βCD-xylan, in alkaline medium at 1:1 mole ratio. Additionally pure βCD gel is also prepared in alkaline medium. The synthesized hydrogels are characterized by Fourier transform infrared spectroscopy, and the swelling ratio, gel fraction, and the morphologies are observed by a microscope. The hydrogels are used to adsorb cadmium (Cd(II)) and nickel (Ni(II)) ions from aqueous solution. The adsorption studies are carried out by varying adsorbent dosage from 80 to 500 mg, concentration from 5 to 500 mg L–1, pH from 2 to 8, and temperature from 25 to 55 °C. The equilibrium adsorption data closely follow the Langmuir model, suggesting the monolayer adsorption of metal ions by the hydrogels. The adsorption kinetics are found to closely follow the pseudo-second-order model.

In this study, a substance flow analysis (SFA) for copper (Cu) was conducted, in which the inflow, stock, and outflow (in the form of diffuse emissions to soil and water) for Stockholm were estimated for 2013 and compared with a previous study from 1995, hence allowing a discussion on changes over time. A large number of applications containing Cu were analyzed (including power cables, copper alloys, heavy electrical equipment, tap water systems, roofs, cars, various consumer electronics, wood preservatives, and contact cables for the railroad). The results show that the inflow of Cu to Stockholm has increased between 1995 and 2013, both in total and per person, mainly as the result of an increase in heavy electrical equipment, power cables, and cars. The stock remains relatively unchanged, whereas the outflow has increased. For the outflow, the emission increase from brake linings is of greatest quantitative importance, with an estimated 5.8 tonnes annual emission of Cu to the environment of Stockholm in 2013 compared to 3.9 tonnes in 1995. Given that increasing inflows of limited resources drive the global demand, continuous monitoring of flows through society and management of outflow routes are crucial, including improvement of national legislation and regional environmental plans as well as efforts to increase resource-use efficiency and recycling.

“…Further, the flows of biological, construction and demolition, and industrial and plastic waste are evaluated. Twenty of the reviewed studies provide an MFA on goods and substances for the same system; on the level of goods, primarily MSW and plastic waste, and on the level of substances, metals (Asari et al 2008;Asari and Sakai 2013;Cain et al 2007;Chen et al 2013;Chen and Graedel 2012b;Guo et al 2010;Huang et al 2014;Kral et al 2014;Krook et al 2007;Kuo et al 2007;Lanzano et al 2006;Long et al 2013;Månsson et al 2009;Morf et al 2013;Oguchi et al 2013;Oguchi et al 2012;Rechberger and Graedel 2002;Saurat and Bringezu 2008;Spatari et al 2002;Spatari et al 2003;Spatari et al 2005; Tanimoto and C are analyzed.

Summary This article reviews, categorizes, and evaluates the objectives, means, and results of the application of material flow analysis (MFA) in waste management. It identifies those areas where MFA methodologies are most successful in supporting waste management decisions. The focus of this review is on the distinction between MFA on the level of goods and on the level of substances. Based on 83 reviewed studies, potentials, strengths, and weaknesses are investigated for the two levels of MFA when applied for analysis, evaluation, and improvement of waste management systems. The differences are discussed in view of effectiveness, applicability, and data availability. The results show that MFA on the level of goods are instrumental for understanding how waste management systems function, facilitating the connections of stakeholders, authorities, and waste management companies. The substance level is essential to assess qualitative aspects regarding resources and environment. Knowledge about the transformation, transport, and storage of valuable and hazardous substances forms the base for identifying both resource potentials and risks for human health and the environment. The results of this review encourage the application of MFA on both levels of goods and substances for decision making in waste management. Because of the mass balance principle, this combination has proven to be a powerful tool for comprehensively assessing if a chosen system reaches designated waste management goals.
