WASTE

Waste according to the Basel convention: Wastes are substances or objects which are disposed or are intended to be disposed or are required to be disposed of by the provisions of national laws.

WHAT IS INDUSTRIAL WASTE?

Industrial waste is a type of waste produced by industrial activity, such as that of factories, mills and mines. It has existed since the outset of the industrial revolution

TYPES OF INDUSTRIAL WASTES

Slag Slag is a partially vitreous by-product of smelting

ore to separate the metal fraction from the worthless fraction. It can be considered to be a mixture of metal oxides; however, slags can contain metal sulfides and metal atoms in the elemental form. While slags are generally used as a waste removal mechanism in metal smelting, they can also serve other purposes, such as assisting in smelt temperature control and minimizing re-oxidation of the final liquid metal product before casting.

Fly ash Fly ash is one of the residues generated in the

combustion of coal. Fly ash is generally captured from the chimneys of coal-fired power plants, and is one of two types of ash that jointly are known as coal ash; the other, bottom ash, is removed from the bottom of coal furnaces. Depending upon the source and makeup of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline) and calcium oxide (CaO), both being endemic ingredients in many coal bearing rock strata.

Sludge Sludge is a generic term for solids separated

from suspension in a liquid. This 'soupy' material usually contains significant quantities of 'interstitial' water (between the solid particles). Commonly sludge refers to the residual, semi-solid material left from industrial wastewater, or sewage treatment processes. It can also refer to the settled suspension obtained from conventional drinking water treatment, and numerous other industrial processes.

TYPES OF INDUSTRIAL POLLUTIONS

Air pollution

Water Pollution

Soil Pollution

AIR POLLUTION Air pollution is defined as the addition

of various hazardous chemicals, particulate matter, toxic substances and biological organisms into the Earth's atmosphere. There are various factors causing air pollution, but what comes from industries and factories is often considered a prime factors in air pollution. According to a study conducted by the Environmental Protection Agency, or EPA, it has been found that industrial pollution accounts for approximately 50 % of the pollution.

AIR POLLUTION

The World Health Organization estimates that about two million people die prematurely every year as a result of air pollution, while many more suffer from breathing ailments, heart disease, lung infections and even cancer.Fine particles or microscopic dust from coal or wood fires and unfiltered diesel engines are rated as one of the most lethal forms or air pollution caused by industry, transport, household heating, cooking and ageing coal or oil-fired power stations.

IMPACT OF AIR POLLUTION

Acid Rain Global warming Respiratory Disorders Ozone layer Depletion Other common effects often associated with

air pollution caused due to industrial emissions include increasing risk of occupational diseases such as pneumoconiosis and asbestosis.

WATER POLLUTION When toxic substances enter lakes,

streams, rivers, oceans, and other water bodies, they get dissolved or lie suspended in water or get deposited on the bed. This results in the pollution of water whereby the quality of the water sources, affecting aquatic ecosystems. Pollutants can also seep down and affect the groundwater deposits.

WATER POLLUTION

According to a United Nations report released on March 22, 2010 on World Water Day that calls for turning unsanitary wastewater into an environmentally safe economic resource. According to the report -- titled "Sick Water?" -- 90 percent of wastewater discharged daily in developing countries is untreated, contributing to the deaths of some 2.2 million people a year from diarrheal diseases caused by unsafe drinking water and poor hygiene.

IMPACT OF WATER POLLUTION

Affecting not only to people but also to animals, fish, and birds.

Polluted water is unsuitable for drinking, recreation, agriculture, and industry.

It diminishes the aesthetic quality of lakes and rivers.

Contaminated water destroys aquatic life and reduces its reproductive ability

SOIL POLLUTION

Soil pollution comprises the pollution of soils with materials, mostly chemicals, that are out of place or are present at concentrations higher than normal which may have adverse effects on humans or other organisms. However, soil pollution is also caused by means other than the direct addition of xenobiotic (man-made) chemicals such as agricultural runoff waters, industrial waste materials, acidic precipitates, and radioactive fallout.

Mithun.M, Manu E.P

SOIL POLLUTION

Both organic (those that contain carbon) and inorganic (those that don't) contaminants are important in soil. The most prominent chemical groups of organic contaminants are fuel hydrocarbons, polynuclear aromatic hydrocarbons ( PAHs ), polychlorinated biphenyls ( PCBs ), chlorinated aromatic compounds, detergents, and pesticides. Inorganic species include nitrates, phosphates, and heavy metals such as cadmium, chromium and lead; inorganic acids; and radionuclide's (radioactive substances). Among the sources of these contaminants are agricultural runoffs, acidic precipitates, industrial waste materials, and radioactive fallout.

Mithun.M, Manu E.P

IMPACT OF SOIL POLLUTION

Soil pollution can lead to water pollution if toxic chemicals leach into groundwater, or if contaminated runoff reaches streams, lakes, or oceans

Soil also naturally contributes to air pollution by releasing volatile compounds into the atmosphere

Nitrogen escapes through ammonia volatilization and denitrification

The decomposition of organic materials in soil can release sulfur dioxide and other sulfur compounds, causing acid rain.

Heavy metals and other potentially toxic elements are the most serious soil pollutants in sewage

Sewage sludge contains heavy metals and, if applied repeatedly or in large amounts, the treated soil may accumulate heavy metals and consequently become unable to even support plant life.
