speech how to save nature from industrial bio and chemical waste
Answers
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, industries, 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, liquid or gaseous. It may be hazardous or non-hazardous waste. Hazardous waste may be toxic, ignitable, corrosive, reactive, or radioactive. Industrial waste may pollute the air, the soil, or nearby water sources, eventually ending up in the sea.[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 every year.[2] Most countries have enacted legislation to deal with the problem of industrial waste, but strictness and compliance regimes vary. Enforcement is always an issue.
Toxic waste, chmical waste, industrial solid waste and municipal solid waste are designations of industrial wastes. 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]
Waste in solid form, but some pollutants within are in liquid or fluid form, e.g. crockery industry or washing of minerals or coal
Waste in dissolved and the pollutant is in the liquid form, e.g. dairy industry
Environmental Impact
Factories and power plants are typically located near bodies of water due to the need for large amounts of water as an input to the manufacturing process, or for equipment cooling. Many areas that are becoming industrialized do not yet have the resources or technology to dispose off the waste with lesser effects on the environment. 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.[4] Effective manners in properly removing waste
Wastewater containing nitrates and phosphates often causes eutrophication which can kill off existing life in the water. 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.[5]
Another obvious effect of industrial waste is air pollution resulting from fossil fuel burning. This affects the lives of many people because this spreads illnesses. Over time, this issue that has been widespread. Several environmental issues have a devastating effect on third world countries because they don't have sufficient resources to solve this particular issue.[6] This also effects the quality of soil because farmers have to try and deal with this massive issue. In addition, nitrogen dioxide is a common air pollutant found in the air. Air pollutants have a devastating effect on the human population because it causes sicknesses. Ammonia also causes a lot of respiratory problems that can be contracted from the air. "Illnesses that can occur from air pollution range from irritation to eyes, skin, nose, or throat. There is also a chance to get Pneumonia or Bronchitis both being very dangerous. Commonly, people have reported to have gotten headaches, nauseam and dizziness from air pollution."[7] The WHO or The World Health Organization has stated that air pollution is the worst risk in terms of human health.[8] Air pollution has been around for a long time. Indoor air pollution is also a risk for humans. This type of air pollution is caused of the burning of solid fuels mostly from cooking or heating.[9]
