Industrial waste

Last updated

Industrial waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories, mills, and mining operations. Types of industrial waste include dirt and gravel, masonry and concrete, scrap metal, oil, solvents, chemicals, scrap lumber, even vegetable matter from restaurants. Industrial waste may be solid, semi-solid or liquid in form. It may be hazardous waste (some types of which are toxic) or non-hazardous waste. Industrial waste may pollute the nearby soil or adjacent water bodies, and can contaminate groundwater, lakes, streams, rivers or coastal waters. [1] Industrial waste is often mixed into municipal waste, making accurate assessments difficult. An estimate for the US goes as high as 7.6 billion tons of industrial waste produced annually, as of 2017. [2] [ better source needed ] Most countries have enacted legislation to deal with the problem of industrial waste, but strictness and compliance regimes vary. Enforcement is always an issue.

Hazardous waste, chemical waste, industrial solid waste and municipal solid waste are classifications of wastes used by governments in different countries. Sewage treatment plants can treat some industrial wastes, i.e. those consisting of conventional pollutants such as biochemical oxygen demand (BOD). Industrial wastes containing toxic pollutants or high concentrations of other pollutants (such as ammonia) require specialized treatment systems. (See Industrial wastewater treatment). [3]

Industrial wastes can be classified on the basis of their characteristics:

Environmental impact

Many factories and most power plants are located near bodies of water to obtain large amounts of water for manufacturing processes or for equipment cooling. [4] In the US, electric power plants are the largest water users. Other industries using large amounts of water are pulp and paper mills, chemical plants, iron and steel mills, petroleum refineries, food processing plants and aluminum smelters. [5]

Many less-developed countries that are becoming industrialized do not yet have the resources or technology to dispose their wastes with minimal impacts on the environment. [6] Both untreated and partially treated wastewater are commonly fed back into a near lying body of water. Metals, chemicals and sewage released into bodies of water directly affect marine ecosystems and the health of those who depend on the waters as food or drinking water sources. Toxins from the wastewater can kill off marine life or cause varying degrees of illness to those who consume these marine animals, depending on the contaminant. Metals and chemicals released into bodies of water affect the marine ecosystems. [7]

Wastewater containing nutrients (nitrates and phosphates) often causes eutrophication which can kill off existing life in water bodies. A Thailand study focusing on water pollution origins found that the highest concentrations of water contamination in the U-tapao river had a direct correlation to industrial wastewater discharges. [8]

Thermal pollution—discharges of water at elevated temperature after being used for cooling—can also lead to polluted water. Elevated water temperatures decrease oxygen levels, which can kill fish and alter food chain composition, reduce species biodiversity, and foster invasion by new thermophilic species. [9]

Solid and hazardous waste

Solid waste, often called municipal solid waste, typically refers to material that is not hazardous. This category includes trash, rubbish and refuse; and may include materials such as construction debris and yard waste. Hazardous waste typically has specific definitions, due to the more careful and complex handling required of such wastes. Under US law, waste may be classified as hazardous based on certain characteristics: ignitability, reactivity, corrosivity and toxicity. Some types of hazardous waste are specifically listed in regulations. [10] [11]

Water pollution

One of the most devastating effects of industrial waste is water pollution. For many industrial processes, water is used which comes in contact with harmful chemicals. These chemicals may include organic compounds (such as solvents), metals, nutrients or radioactive material. If the wastewater is discharged without treatment, groundwater and surface water bodies—lakes, streams, rivers and coastal waters—can become polluted, with serious impacts on human health and the environment. Drinking water sources and irrigation water used for farming may be affected. The pollutants may degrade or destroy habitat for animals and plants. In coastal areas, fish and other aquatic life can be contaminated by untreated waste; beaches and other recreational areas can be damaged or closed. [12] : 273–309  [13]

Management

Thailand

In Thailand the roles in municipal solid waste (MSW) management and industrial waste management are organized by the Royal Thai Government, which is organized as central (national) government, regional government, and local government. Each government is responsible for different tasks. The central government is responsible for stimulating regulation, policies, and standards. The regional governments are responsible for coordinating the central and local governments. The local governments are responsible for waste management in their governed area. [14] However, the local governments do not dispose of the waste by themselves but instead hire private companies that have been granted the right from the Pollution Control Department (PCD) in Thailand. [15] The main companies are Bangpoo Industrial Waste Management Center, [16] General Environmental Conservation Public Company Limited (GENCO), [17] SGS Thailand, [18] Waste Management Siam LTD (WMS), [19] and Better World Green Public Company Limited (BWG). [20] These companies are responsible for the waste they have received from their customers before releasing it to the environment, burying it.

United States

The 1976 Resource Conservation and Recovery Act (RCRA) provides for federal regulation of industrial, household, and manufacturing solid and hazardous wastes in the United States. [11] [21] RCRA aims to conserve natural resources and energy, protect human health, eliminate or reduce waste, and to clean up waste when needed. [21] RCRA first began as an amendment to the Solid Waste Disposal Act of 1965, and in 1984, Congress passed the Hazardous and Solid Waste Amendments (HSWA) which strengthened RCRA by: [22]

Furthermore, the EPA uses Superfund to find sites of contamination, identify the parties responsible, and in the occurrences where said parties are not known or able to, the program funds cleanups. [27] Superfund also works on figuring out and applying final remedies for cleanups. The Superfund process is to: 1) collect necessary information (known as the Remedial Investigation (RI) phase); 2) assess alternatives to deal with any potential risks to the environmental and human health (known as the Feasibility Study (FS) stage); 3) determine the most suitable remedies that could lower the risks to more adequate levels. [27] Some sites are so contaminated because of past waste disposals that it takes decades to clean them up, or bring the contamination down to acceptable levels, thus requiring long-term management over those sites. Hence, sometimes figuring out a final remedy is not possible, and so, the EPA has developed the Adaptive Management plan. [27]

The EPA has issued national regulations regarding the handling, treatment and disposal of wastes. EPA has authorized individual state environmental agencies to implement and enforce the RCRA regulations through approved waste management programs. [28]

State compliance is monitored by EPA inspections. In the case that waste management guideline standards are not met, action against the site[ which? ] will be taken. Compliance errors may be corrected by enforced cleanup directly by the site responsible for the waste or by a third party hired by that site. [28] Prior to the enactment of the Clean Water Act (1972) and RCRA, open dumping or releasing wastewater into nearby bodies of water were common waste disposal methods. [29] The negative effects on human health and environmental health led to the need for such regulations. The RCRA framework provides specified subsections defining nonhazardous and hazardous waste materials and how each should be properly managed and disposed of. Guidelines for the disposal of nonhazardous solid waste includes the banning of open dumping. Hazardous waste is monitored in a "cradle to grave" fashion; each step in the process of waste generation, transport and disposal is tracked. The EPA now[ when? ] manages 2.96 million tons of solid, hazardous and industrial waste. Since establishment, the RCRA program has undergone reforms as inefficiencies arise and as waste management processes evolve. [28]

The 1972 Clean Water Act is a broad legislative mandate to protect surface waters (rivers, lakes and coastal water bodies). [30] A 1948 law had authorized research and development of voluntary water standards, and had provided limited financing for state and local government efforts. The 1972 law prohibited, for the first time, uncontrolled discharges of industrial waste, as well as municipal sewage, into waters of the United States. EPA was required to develop national standards for industrial facilities and standards for municipal sewage treatment plants. States were required to develop water quality standards for individual water bodies. Enforcement is mainly delegated to state agencies. Major amendments to the law were passed in 1977 and 1987. [31]

A pollutant or novel entity is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. These can be both naturally forming or anthropogenic in origin. Pollutants result in environmental pollution or become public health concerns when they reach a concentration high enough to have significant negative impacts.

<span class="mw-page-title-main">Hazardous waste</span> Ignitable, reactive, corrosive and/or toxic unwanted or unusable materials

Hazardous waste is waste that must be handled properly to avoid damaging human health or the environment. Waste can be hazardous because it is toxic, reacts violently with other chemicals, or is corrosive, among other traits. As of 2022, humanity produces 300-500 million metric tons of hazardous waste annually. Some common examples are electronics, batteries, and paints. An important aspect of managing hazardous waste is safe disposal. Hazardous waste can be stored in hazardous waste landfills, burned, or recycled into something new. Managing hazardous waste is important to achieve worldwide sustainability. Hazardous waste is regulated on national scale by national governments as well as on an international scale by the United Nations (UN) and international treaties.

<span class="mw-page-title-main">Chemical waste</span> Waste made from harmful chemicals

Chemical waste is any excess, unused, or unwanted chemical. Chemical waste may be classified as hazardous waste, non-hazardous waste, universal waste, or household hazardous waste, each of which is regulated separately by national governments and the United Nations. Hazardous waste is material that displays one or more of the following four characteristics: ignitability, corrosivity, reactivity, and toxicity. This information, along with chemical disposal requirements, is typically available on a chemical's Safety Data Sheet (SDS). Radioactive and biohazardous wastes require additional or different methods of handling and disposal, and are often regulated differently than standard hazardous wastes.

<span class="mw-page-title-main">Toxic waste</span> Any unwanted material which can cause harm

Toxic waste is any unwanted material in all forms that can cause harm. Mostly generated by industry, consumer products like televisions, computers, and phones contain toxic chemicals that can pollute the air and contaminate soil and water. Disposing of such waste is a major public health issue.

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants. Most industrial processes, such as petroleum refineries, chemical and petrochemical plants have their own specialized facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the regulations regarding disposal of wastewaters into sewers or into rivers, lakes or oceans. This applies to industries that generate wastewater with high concentrations of organic matter, toxic pollutants or nutrients such as ammonia. Some industries install a pre-treatment system to remove some pollutants, and then discharge the partially treated wastewater to the municipal sewer system.

In environmental law, the polluter pays principle is enacted to make the party responsible for producing pollution responsible for paying for the damage done to the natural environment. This principle has also been used to put the costs of pollution prevention on the polluter. It is regarded as a regional custom because of the strong support it has received in most Organisation for Economic Co-operation and Development (OECD) and European Union countries, and has a strong scientific basis in economics. It is a fundamental principle in US environmental law.

To protect the environment from the adverse effects of pollution, many nations worldwide have enacted legislation to regulate various types of pollution as well as to mitigate the adverse effects of pollution. At the local level, regulation usually is supervised by environmental agencies or the broader public health system. Different jurisdictions often have different levels regulation and policy choices about pollution. Historically, polluters will lobby governments in less economically developed areas or countries to maintain lax regulation in order to protect industrialisation at the cost of human and environmental health.

An ash pond, also called a coal ash basin or surface impoundment, is an engineered structure used at coal-fired power stations for the disposal of two types of coal combustion products: bottom ash and fly ash. The pond is used as a landfill to prevent the release of ash into the atmosphere. Although the use of ash ponds in combination with air pollution controls decreases the amount of airborne pollutants, the structures pose serious health risks for the surrounding environment.

<span class="mw-page-title-main">Waste management law</span> Area of law regarding waste

Waste management laws govern the transport, treatment, storage, and disposal of all manner of waste, including municipal solid waste, hazardous waste, and nuclear waste, among many other types. Waste laws are generally designed to minimize or eliminate the uncontrolled dispersal of waste materials into the environment in a manner that may cause ecological or biological harm, and include laws designed to reduce the generation of waste and promote or mandate waste recycling. Regulatory efforts include identifying and categorizing waste types and mandating transport, treatment, storage, and disposal practices.

Solid waste policy in the United States is aimed at developing and implementing proper mechanisms to effectively manage solid waste. For solid waste policy to be effective, inputs should come from stakeholders, including citizens, businesses, community-based organizations, non-governmental organizations, government agencies, universities, and other research organizations. These inputs form the basis of policy frameworks that influence solid waste management decisions. In the United States, the Environmental Protection Agency (EPA) regulates household, industrial, manufacturing, and commercial solid and hazardous wastes under the 1976 Resource Conservation and Recovery Act (RCRA). Effective solid waste management is a cooperative effort involving federal, state, regional, and local entities. Thus, the RCRA's Solid Waste program section D encourages the environmental departments of each state to develop comprehensive plans to manage nonhazardous industrial and municipal solid waste.

There are many exemptions for fracking under United States federal law: the oil and gas industries are exempt or excluded from certain sections of a number of the major federal environmental laws. These laws range from protecting clean water and air, to preventing the release of toxic substances and chemicals into the environment: the Clean Air Act, Clean Water Act, Safe Drinking Water Act, National Environmental Policy Act, Resource Conservation and Recovery Act, Emergency Planning and Community Right-to-Know Act, and the Comprehensive Environmental Response, Compensation, and Liability Act, commonly known as Superfund.

<span class="mw-page-title-main">Solid Waste Disposal Act of 1965</span>

The Solid Waste Disposal Act (SWDA) is an act passed by the United States Congress in 1965. The United States Environmental Protection Agency described the Act as "the first federal effort to improve waste disposal technology". After the Second Industrial Revolution, expanding industrial and commercial activity across the nation, accompanied by increasing consumer demand for goods and services, led to an increase in solid waste generation by all sectors of the economy. The act established a framework for states to better control solid waste disposal and set minimum safety requirements for landfills. In 1976 Congress determined that the provisions of SWDA were insufficient to properly manage the nation's waste and enacted the Resource Conservation and Recovery Act (RCRA). Congress passed additional major amendments to SWDA in the Hazardous and Solid Waste Amendments of 1984 (HSWA).

<span class="mw-page-title-main">Environmental cleanup law</span> Area of law

Environmental cleanup laws govern the removal of pollution or contaminants from environmental media such as soil, sediment, surface water, or ground water. Unlike pollution control laws, cleanup laws are designed to respond after-the-fact to environmental contamination, and consequently must often define not only the necessary response actions, but also the parties who may be responsible for undertaking such actions. Regulatory requirements may include rules for emergency response, liability allocation, site assessment, remedial investigation, feasibility studies, remedial action, post-remedial monitoring, and site reuse.

Water in Arkansas is an important issue encompassing the conservation, protection, management, distribution and use of the water resource in the state. Arkansas contains a mixture of groundwater and surface water, with a variety of state and federal agencies responsible for the regulation of the water resource. In accordance with agency rules, state, and federal law, the state's water treatment facilities utilize engineering, chemistry, science and technology to treat raw water from the environment to potable water standards and distribute it through water mains to homes, farms, business and industrial customers. Following use, wastewater is collected in collection and conveyance systems, decentralized sewer systems or septic tanks and treated in accordance with regulations at publicly owned treatment works (POTWs) before being discharged to the environment.

Brook Industrial Park (BIP) is an industrial area occupying 4.5 acres of the Borough of Bound Brook, New Jersey, in the United States of America. It is located on the northern bank of the Raritan River. Industrial, chemical and pesticide operations began in 1971 and eventually lead to the contamination of groundwater and exposure of workers to harmful dioxins. Throughout 1980 to 1988 the United States Environmental Protection Agency (EPA) and the New Jersey Department of Environmental Protection (NJDEP) conducted studies to determine if there were any threats being posed on the workers, community or environment by the BIP companies in their disposal of processed and stored chemicals.
