New methodology for hazardous waste classification using fuzzy set theory

Hazardous and industrial waste composition and associated management activities in Caspian industrial park, Iran

“…Today, industries and other generators are legally responsible for managing their waste. (Thandavamoorthy, 2016;Musee et al, 2008). Therefore, the manufacturers should manage the wastes themselves, or contract with qualified companies to collect and dispose of the wastes.…”

New methodology for hazardous waste classification using fuzzy set theory

“…Primarily the level at which a given leaf terminates, signifies the point where the system prompts the user for a crisp, fuzzy or a linguistically defined input to initialize the calculations for all the higher levels composite outputs in that particular leaf. The input data for the lowest level attributes were sourced from numerous bibliographical references as described in part I of this paper [1].…”

“…In our algorithm, these categories were represented by using both fuzzy triangular and trapezoidal distribution functions, as shown in Fig. 3 (detailed description of these classes was presented in part I of this work [1]). To obtain numerical scores, four linear algebraic equations were developed to compute the crisp input values in accordance to the dominant virus group, as a function of the constituent percentage of the viruses to the entire population of pathogens.…”

“…In part I [1], both tacit and implicit knowledge on factors that influence the extent to which a certain waste is classified as hazardous or benign were presented. Through an extensive bibliographical search, knowledge on waste classification was acquired from diverse sources, exhibiting both qualitative and quantitative features characterized by varying degrees of uncertainty.…”

Hazardous waste management and weight-based indicators—The case of Haifa Metropolis

“…For example, in the USA, the Environmental Protection Agency (EPA) defines HW based on physicochemical characteristics, viz. corrosivity, flammability (ignitability), reactivity or toxicity, and a set of lists (F-, K-, P-and U-codes) [2].…”
