“…Most methods currently implemented emphasize reducing energy consumption, improving energy efficiency, and developing alternative energy resources (Lund, 2007;Ozalp and Hyman, 2006;Dincer and Rosen, 1999;Thollander et al, 2007) in order to alleviate dependence on fossil fuels and the adverse impact on environment (Bari et al, 2011;Chen et al, 2011). New equipment and technology are needed (Xue and Aggarwal, 2003;Barroso et al, 2004;Lunghi and Burzacca, 2004) for improving energy efficiency, developing alternate energy resources, strengthening energy management, renovating equipment with better efficiencies, and recovering waste energy (Lunghi and Burzacca, 2004;Ptasinski et al, 2006). For instance, in the waste recycling industry, scrap iron is recycled to reduce the demand for more energy-intensive virgin materials (Holmgren and Henning, 2004).…”
