“…A weighted multi-objective optimization approach on the basis of theoretical data and an analytic hierarchical process was also presented. Hogland and Stenis (2000) introduced an analysis based on Life Cycle Assessment (LCA), including economic and energy objectives. Their method presented the implementation of a new waste management system for an industrial site and compared the base case to the energy optimization alternative and the material recovery optimization alternative.…”

A multi-objective optimization methodology for hazardous liquid waste management is presented in this paper using industrially based LCA models and operating constraints. This approach is used to optimize the handling of waste streams introducing flexible mixing policy scenarios compared to the rigid policy scenarios of the industrial system. It is shown that increasing the degrees of freedom for the waste mixing reduces significantly both the operating cost and the environmental impact by avoiding the use of utilities. Moreover, the influence of waste availability as function of production planning without waste storage is analyzed in several multiperiod optimizations. There, it is demonstrated that this saving potential can be further increased by integration of multiperiod production planning with waste management policies, up to the level of 40% for the environmental impact, and more than 50% for the operating cost, compared to the industrial base case. In some specific cases, a proper matching of production planning and waste mixing policies can also turn the waste treatment into a source of profit exploiting energy production from the incineration process.Implications: This study reveals the savings potential of more flexible policies in waste management, in particular waste mixing of liquid waste in batch chemical industries treated in incineration, wet air oxidation, wastewater treatment plants, or recovered by distillation. Through a multi-objective optimization framework including models for operating costs and life-cycle inventories based on industrial data, operating constraints from industrial practice, and terminal constraints from legislation, savings potentials up to 50% for the operation cost and 40% for the environmental impact are demonstrated in two case studies.

Assessment of Waste Production and Heavy Metal Emission from Energy Production Sector of Zahedan City

Background and purpose: Due to the lack of accurate statistics on the amount of waste generated in the energy production sector in Zahedan, before any planning, one should identify all waste producing centers associated with the energy sector and also the quantity and quality of their waste in Zahedan. Materials and Methods:This research is a cross-sectional descriptive study. It examined the produced wastes in the electrical energy generation sector. A questionnaire was prepared and completed for each unit that possibility produces these wastes. Moreover, in the studied units, the weigh percent per unit was determined by separating production waste, and collecting and weighing them.Results: In gas power plant of Zahedan, production of burned oil was approximately 480 liters and the annual consumption of turbine oil and compressor oil was 40 liters. In the diesel power plant, 2,200 liters of burned oil is produced for each generator after 1,500 hours of work. Concentration of heavy metals of Cr, Cd, Zn, Pb, Cu, and Ni in the burned oil sample of the gas power plant was 43.2, 0.01, 0.20, 1.3, 2.7, 0.2 mg/l, respectively; and in the diesel power plant were 36.3, 0.08, 0.09, 0.9, 4.7, 1.1 mg/l.Conclusion: In the studied samples, several cases of heavy metal pollution were identified. Therefore, proper planning for appropriate management of these units is necessary for any possible leakage and environmental pollution transport. Furthermore, in order to minimize the adverse impacts of hazardous wastes on the environment and people in Zahedan, integrated hazardous wastes management should be practices in electrical energy generation plants. Moreover, one must consider the measures required to exposure, transport, and safe maintenance before managing or eliminating this type of waste.
