Abstract
Global warming is the major problem of the modern world due to environmental pollution, where hazardous waste disposal poses threat to the environment. USA is urbanized country but still going through hard time due to indecorous management of hazardous waste. To manage such problem are always difficult for the related parties because every individual have their own judgement. Which is difficult to put everyone opinions together for the decision making. The objective of this study was to elucidate hazardous waste problem of USA. This paper espouses VIKOR (VIseKriterijumska Optimizacija I Kompromisno Resenje) methods which is prevalent method applied in multi-criteria analysis (MCA). The empirical studies ranked each state of USA from best to worst for hazardous waste management and will help EPA (environmental protection agency) to improve hazardous waste of each state by comparing with the best.
Highlights
Hazardous waste is any unsolicited material or solid waste which is disposed in open environment and causes threat to it
A waste is considered hazardous when it stances a threat to human health or the environment stated by USA Resource Conservation and Recovery Act (RCRA) of 1978
For enhancing multi-response problems, some methodical processes have been developed in recent years but in this study a systematic technique is used that involves applying the multi-criteria decision making (MCDM) compromise ranking method VIKOR to optimize what factors are contributing to the hazardous waste of a developed country like USA

It can be in any form such as explosive, emitting radiation, eroding materials, toxic etc. There are numerous ways to extravagance those waste such as neutralization, reduction, oxidation, hydrolysis, microorganisms, incineration, encapsulation and separation etc It indicates identification and confirmation of the chemical and physical properties of waste, where this is done either by testing or applying knowledge of waste. If such hazardous waste were well managed there would be clean environment and not essential to perform any site remediation. Speedy improvement and upgrading of various industries machineries, products and practices normally increase the generation rate of hazardous substances
