Operating Policies

The basic strategies for optimizing processing schedules of hazardous waste in an integrated hazardous waste treatment facility are analyzed. Five schedule optimization heuristics were evaluated on six simulation models of hypothetical integrated hazardous waste treatment facilities. The six models represented combinations of one of three unit process configurations and one of two facility operating policies. The heuristics were evaluated with respect to their ability to minimize the average completion time (makespan) of a specified set of jobs. The same five heuristics were applied to a model representing the physical and chemical treatment plant of the Alberta Special Waste Management Corporation. Operation under two operating policies for this case study was evaluated, and the results were compared with the hypothetical model results. Some heuristics were found to be capable of reducing makespans by 13–14% relative to the first in, first out heuristic. Key words: hazardous waste treatment, scheduling, heuristics, simulation modelling.

As a rule, hazardous waste needs a pre-treatment, either a thermal or a chemical-physical one, before it can be disposed of at a landfill. The concentration of different kinds of treatment facilities at a Centralized Hazardous Waste Treatment Plant is advantageous. The facility of the ZVSMM at Schwabach is presented as an outstanding example of this kind of Treatment Centre. The infrastructure, the chemical-physical plant with separate lines for the treatment of organic and inorganic waste and the hazardous waste incinerator are described. Their functions are discussed in detail. Emphasis is laid on handling the residues produced by the different treatment processes and the final disposal.
