waste management

Waste management is become a major environment protection concern in recent years, as the number and complexity of waste streams has increased, as a result of our consumer-based society’s ever-growing product range. Since the early 1980s, when uncontrolled toxic waste were linked to serious health consequences in populations exposed at Love Canal, New York, and Times Beach, Missouri, hazardous waste has been subject to extensive and costly regulations. Although the US legislative reaction has been thorough, there are still a slew of issues that require more sophisticated management inside the US regulatory framework. Hazardous waste & municipal solid trash are the two types of waste that are regulated in the United States. Combined, the two categories produced almost 422 million tones in 1995–96. Despite the fact which it comprises domestic hazardous trash, solid waste is not deemed hazardous. Despite the fact that household waste includes a mixture of inert & dangerous components, it is classified like municipal solid waste and is not subject to the same stringent federal rules as hazardous waste.

 

The federal government administers regulations dealing with emissions of hazardous substances that may damage public health, welfare, or the environment via the US Environmental Protection Agency (EPA). The EPA had developed risk assessment processes to estimate the size and hazard of such discharges. Quantitative risk assessment is  method for assessing hazards, exposures, and the likelihood of adverse health impacts on target populations.

This overview of US waste management regulations discusses some of the current difficulties in risk-based decision-making, as well as risk assessment methods developed by the EPA over the last twenty-five years. As new scientific knowledge becomes available, risk assessment technique is continually growing and being enhanced. It has lately been broadened to include ecological risk, and it is used to assess hazards to a wide range of human and animal health impacts. This methodology is used in most environmental regulation in the United States that deal with harmful discharges.
