TABLE OF CONTENTS

Industrial emissions are one of the causes of environmental pollution. As industries grow, so does the generation of industrial emissions. Let’s learn about industrial emissions and effective industrial waste treatment solutions.

Introduction to industrial emissions

Industrial emissions are industrial wastes that exist in the form of gases and dust. They arise through stages and operations in factories and industrial parks. It is then released into the environment. And cause serious harm to the environment and human health.

Industries that generate a lot of harmful emissions

Many industries have the characteristics of generating a lot of industrial emissions. The source of emissions in each industrial park is different, leading to different compositions and concentrations of industrial emissions. The following industries are typical of the large emitters of industrial emissions.

Thermal power industry

Electricity plays an important role in all activities of life. What if the whole world lost power for 1 hour? Can’t imagine, right? Thermal power plants must work at full capacity to provide enough electricity needed for all operations. Thermal power plants produce a mixture of harmful gases such as CO, CO2, NOx, SO2… The emissions from thermal power plants are considered “accomplices” causing the greenhouse effect. Pollution levels of PM 2.5 fine dust caused by coal-fired power plants are warned to reach serious levels by 2030.

Coal mining and processing industry

Coal is one of the important fuels for many industries. Typically, coal is used for thermal power plants, steel mills, or the cement production industry… Coal mining is a big challenge for global climate change. The average coal mining output of the world is about 5 billion tons/year. According to statistics, more than 40% of electricity in the world is produced from coal-fired power plants. Each year in China, about 1 million people die from air pollution caused by industrial smog related to coal use. It can be said that the coal mining industry is a direct threat to the existence of the Earth.

Cement manufacturing industry

Cement is a material that plays an extremely important role in the construction field. In 2020, the world consumes more than 4 billion tons of cement. In particular, cement contains oxides that cause negative impacts on the environment and human health. Silica dust in cement is ranked 2nd on the list of toxic substances in the construction industry (after asbestos).

Steel manufacturing industry

Steel is also one of the extremely important and indispensable building materials in the construction industry. According to statistics, 60% of global steelmaking capacity uses blast furnace production method – oxygen blast furnace. This method of making steel releases huge amounts of carbon into the environment. Emissions in the steel industry contain many pollutants such as acids, alkalis, alloying elements, etc. To produce 1 ton of steel, about 10,000 m2 of exhaust gas and 100 kg of dust are generated. Carbon emissions from the steel industry contribute to global warming.

Industries using boilers

Boilers have high applications in many different industries such as confectionery production, monosodium glutamate production, beverage production such as beer, soft drinks, etc. Using a boiler needs to burn a large amount of fuel at high temperatures. The amount of exhaust gas generated from the combustion of a fuel produces a large amount of exhaust gas that pollutes the environment.

Transportation

Emissions from vehicles will account for 27% of greenhouse gas emissions in 2020. Emissions from burning fossil fuels for vehicles such as ships, cars, and trucks. , airplanes … More than 90% of the fuel is used for transportation such as gasoline, oil …

Effects of industrial emissions

Industrial emissions have adverse effects on the environment and people. As follows:

Negative impact on the environment

The production of industrial emissions into the environment is increasing, leading to serious environmental pollution. The accumulation of industrial emissions is the main cause of acid rain. The reaction of industrial exhaust gases with moisture in the air forms an acid precipitate. Acid rain changes the pH of ponds and lakes. For plants, acid rain can cause plants to burn. Many forests are also affected because of that.

In large concentrations, industrial emissions cause the greenhouse effect. This leads to increasing global warming, causing a hole in the ozone layer. Climate change appears more and more, causing storms, floods, melting ice …

The environment is increasingly polluted, which has serious effects on the ecosystem. Changing the living environment of animals and plants affects their growth and development.

Impact on human health

When people have to live in a severely polluted environment. With daily inhalation of harmful gases in the environment, the amount of fine dust PM 2.5 is increasing day by day. They are dangerous agents that cause potential diseases to human health.

For workers directly working in industrial zones, their health is threatened by polluting emissions.

The workers must be in direct contact with the exhaust gas through the skin, eyes, nose, mouth… When in contact with the eyes, they can immediately see symptoms such as eye pain, burning eyes, burning eyes, red eyes… And it is extremely dangerous to inhale harmful emissions. Exhaust gases and industrial dust pass through the respiratory tract and go deep into the body parts. This is the cause of dangerous diseases. Even cancer.

When people live in a polluted environment, it will gradually affect their health and quality of life.

Therefore, it is necessary to take measures to reduce industrial emissions and protect the living environment as well as human health.

Measures to reduce industrial emissions

Here are some measures to reduce industrial emissions:

For industrial zones

– Some factories use outdated machinery and equipment, causing a lot of emissions during operation. New machinery and equipment should be replaced to reduce emissions.

– Replace harmful fuel sources with clean ones. Replacing coal-fired thermal power plants with clean raw materials that do not generate or generate low industrial emissions.

– Do not discharge industrial emissions directly into the environment. To reduce industrial emissions, regulations on industrial emissions of countries were introduced. Ensure that industrial parks comply with regulations on industrial emissions, minimizing emissions to the environment. Factories and industrial parks need to design exhaust gas treatment systems, convert harmful emissions, and minimize emission concentrations according to the regulations of each country before discharging them into the environment. The exhaust gas treatment systems from which are known. So that the concentration of exhaust gas discharged into the environment is as low as possible.

For life

– Replacing vehicles that use burning fuel with vehicles using clean materials. For example, reducing the number of motorbikes and cars powered by gasoline and oil into vehicles such as electric motorbikes and electric cars.

– Limit the use of plastic, non-biodegradable items. To reduce waste in the environment. Reduce environmental pollution.

– Reuse waste to become useful items.

– Planting trees helps the surrounding environment reduce pollution, supplement oxygen, and clean air for people living around.
