Discarded Material same in all countries, the differences in regulations make the determination subjective which creates a serious problem in management of these wastes.
Can it be reused, recovered and/or recycled?
Is it defined in your wastewater, municipal solid waste and/or air pollution control regulations?
Hazardous Waste Determination
Has it hazard criteria?
Non-Regular WasteRating System
Table 1 hazard characteristics and to determine the hazardous wastes with easy and understandable numbers in a simple scale.
Table 2 source and composition of the waste is an important aspect for determination of the hazard characteristics of a waste and their listing accordingly.
Rating Values for Hazardous Waste Lists
Table3 “t” is the dimensionless toxicity value of the rating system. LC50 value obtained from bioassay test is used to grade the toxicity in the rating system.
Rating Values for Components of Ecological Effects
Table 4 almost similar to the quantification of the environmental risk (LC50), and is given by LD50 which is the lethal dose to 50 percent of an exposed population of humans within a given time . LD50 for quantifying the toxic characteristics P are tabulated in Table 4.
Rating Values for Combined Potential Risks Eq (7)
Depending on descriptive classification of bioaccumulation characteristic of a matter, dimensionless bioaccumulation value of the rating system Bac, Bd and Sl values are also given in Table 5.
Evaluation of Persistency Values Eq(9)
Table 6 evaluation of the combined potential risk because of fate of the waste in the environment is relevant to its physical form. For instance, different risk assessments should be made for waste in solid form or gas form.
Rating Values for Physical Form

Scaling of Rating System consideration of quantity of the waste and its recurrent rate of arising.
Projection of the ORVs, which are obtained from the model equations for hazardous waste determination, is considered with an “hourglass” scale that shown in Figure 2.
Table 8 wastes, lower part represents both non-regular and hazardous waste. Bottleneck points the zero level which separates regular waste from non-regular waste.
