Hazardous waste

1st Edition

These dangers can happen when wastes are improperly treated, stored, transported, disposed of, or otherwise managed. Hazardous wastes come in many forms and there is a determination process [PDF] to help with classifications as well as an audit businesses can conduct on themselves [DOC]. These wastes can be liquid, solid, semisolid, or contained gases.


Solid and Hazardous Waste Management: Science and Engineering presents the latest on the rapid increase in volume and types of solid and hazardous wastes that have resulted from economic growth, urbanization, and industrialization and how they have challenged national and local governments to ensure effective and sustainable management of these waste products. The book offers universal coverage of the technologies used for the management and disposal of waste products, such as plastic waste, bio-medical wastes, hazardous wastes, and e-wastes. He then joined Govt. Rao published Technical papers in National and International Journals, 25 manuals, 5 textbooks and 15 video lessons. Phil and PhD students. Sultana assisted the Andhra Pradesh Government in bringing out special legislation on Water, Land andTrees Act, and organized training programs, executed environmental projects and conducted research for national and international agencies. His research is focused on developing emission inventories from mobile sources and landfills, urban air quality monitoring and modeling, noise pollution, developing indoor air purification systems, regional air quality modeling, and climate change.

Hazardous waste is waste that has substantial or potential threats to public health or the environment. Hazardous wastes may be found in different physical states such as gaseous, liquids, or solids. A hazardous waste is a special type of waste because it cannot be disposed of by common means like other by-products of our everyday lives. Depending on the physical state of the waste, treatment and solidification processes might be required. The international community has defined the responsible management of hazardous waste and chemicals as an important part of developing a sustainable economy with Sustainable Development Goal Target

Hazardous waste

Hazardous, or toxic, waste is the potentially dangerous byproduct of a wide range of activities, including manufacturing, farming, water treatment systems, construction, automotive garages, laboratories, hospitals, and other industries. The waste may be liquid, solid, or sludge and contain chemicals, heavy metals, radiation, pathogens, or other materials. Even households generate hazardous waste, from items such as batteries, used computer equipment, and leftover paints or pesticides. Toxic waste can harm people, animals, and plants, whether it ends up in the ground, in streams, or even in the air. Some toxins, such as mercury and lead , persist in the environment for many years and accumulate over time.

As long as people have been living in settlements and residential areas, garbage or solid waste has been an issue. Waste management is all about how solid waste can be changed and used as a valuable resource. Solid waste management should be embraced by each and every household, including the business owners across the world. The industrialization has brought a lot of good things and bad things as well. According to Britannica ,. Improper disposal of municipal solid waste can create unsanitary conditions, and these conditions in turn can lead to pollution of the environment and to outbreaks of vector-borne disease—that is, diseases spread by rodents and insects.

This chapter provides an overview of waste generation, waste stream composition, and incineration in the context of waste management. Communities are faced with the challenge of developing waste-management approaches from options that include reduction of waste generated, incineration, landfilling, recycling, reuse, 1 and composting. Waste-management options other than incineration are discussed here to illustrate that a combination of options, such as recycling, with incineration can alter the characteristics of waste streams fed to incineration facilities. However, the committee was not charged to undertake a comparative assessment of waste-management options.

1st Edition

Several options are available for hazardous-waste management. The most desirable is to reduce the quantity of waste at its source or to recycle the materials for some other productive use. Nevertheless, while reduction and recycling are desirable options, they are not regarded as the final remedy to the problem of hazardous-waste disposal. There will always be a need for treatment and for storage or disposal of some amount of hazardous waste. Hazardous waste can be treated by chemical, thermal, biological, and physical methods.

    The Environmental Protection Agency EPA defines solid waste as any garbage or refuse, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded material, including solid, liquid, semi-solid, or contained gaseous material resulting from industrial, commercial, mining, and agricultural operations, and from community activities.
