“…The use of optimization modeling to support INSM's BU has been applied in a variety of waste settings, with differing objectives and optimization methods (Zhang et al, 2014, Crohn and Thomas, 1998, Sahakij, 2008, Sundburg et al, 1994, Chang and Wang, 1997, RTI International, 2002, Jin et al, 2013. The BUDSS optimizer is based on a commonly used genetic algorithm approach made popular by Goldberg (1989), because of its flexibility with respect to linear/non-linear features, constraints, robustness to finding global optima, and open source/expansibility.…”

Non-hazardous solid materials from industrial processes, once regarded as waste and disposed in landfills, offer numerous environmental and economic advantages when put to beneficial uses (BUs). Proper management of these industrial non-hazardous secondary materials (INSM) requires estimates of their probable environmental impacts among disposal as well as BU options. The U.S. Environmental Protection Agency (EPA) has recently approved new analytical methods (EPA Methods 1313-1316) to assess leachability of constituents of potential concern in these materials. These new methods are more realistic for many disposal and BU options than historical methods, such as the toxicity characteristic leaching protocol. Experimental data from these new methods are used to parameterize a chemical fate and transport (F&T) model to simulate long-term environmental releases from flue gas desulfurization gypsum (FGDG) when disposed of in an industrial landfill or beneficially used as an agricultural soil amendment. The F&T model is also coupled with optimization algorithms, the Beneficial Use Decision Support System (BUDSS), under development by EPA to enhance INSM management.

“…The authors recommended the use of dimethyl disulfide and dimethyl trisulfide as chemical markers for odor annoyance and the use of straight chain alkanes to monitor the fate of biosolids after soil incorporation (Laor, Naor et al, 2011). Overall, the study, in addition to developing new odor threshold calculations to rank the odor sensitivities for reuse fields, determined better odor-cost tradeoff could be obtained when the flow handled by the wastewater treatment plant was defined as a decision variable (endogenously determined) (Sahakij et al, 2011). The modeling of indoor sources was examined by Wang et al…”
