POLLUTING FACTORIES: CHARACTERISTICS AND TYPES - ENVIRONMENT - 2025

The polluting factories are industrial sources made by the man whose generating pollution emissions have profound effects on the health of living organisms. They are one of the main sources of environmental pollution on the entire planet.

Human activity emits a wide range of pollutants in factories and industries, such as carbon monoxide, nitrogen oxides, ammonia, particulates, lead, hydrocarbons, organic compounds, and other chemicals.

Global factory process emissions are increasing year after year and although it has become a public health problem, countries are reluctant to regulate these tremendous industries.

Inhalation of fumes in factories and industries is very dangerous for human health, which increases the probability of various diseases. The world is in permanent disease due to this problem, and climate change will not stop if manufacturing industries are not regulated.

The lack of control policies, the use of old technologies and the inefficient disposal of waste drive this process of massive contamination.

characteristics

Polluting factories have increased steadily since the Industrial Revolution, due to consumer demand and dependence on conventional energy resources such as coal and oil.

Pollution from factories is often considered to be just emissions from the most visible stacks.

Some factories also pollute the water and land around them. Although not all contaminants can be visibly detected, after they enter the atmosphere or water they can spread beyond the factory.

Air pollution

Factories need a source of energy to drive their production processes. This is the electricity generated by burning fossil fuels.

Power generation for factories can cause more air pollution than factory processes themselves.

This pollution occurs when substances that shouldn't be there are added to the air. For example, when burning fuels release particles.

Air pollutants emitted from coal-fired power plants include carbon dioxide, sulfur oxides, and hydrogen chloride, as well as arsenic, lead, and other metals.

Acid rain

Acid rain occurs when emissions from the factory combine with moisture in the air to form acid precipitation. Acid rain changes the pH of lakes and ponds.

Ozone

Chemical reactions create another air pollutant, ozone. It is formed by sunlight, nitrous oxide, and volatile organic compounds in the air, such as emissions from fossil fuels, chemical solvents, and by-products of industrial processes.

When ozone stays close to the earth's surface, it becomes detrimental to human and environmental health.

Climate change

Air pollution caused by factories is one of the main causes of climate change. Air is directly affected, but the effects go far beyond air quality problems.

Greenhouse gas emissions can cause physical damage to plants and reduce crop yields.

Solid waste

Much of it is classified as non-hazardous, such as construction material (wood, concrete, bricks, etc.) and medical waste (bandages, gloves, etc.).

Factory waste is a significant portion of hazardous solid waste, as it contains potentially dangerous properties for human health and the environment.

Factories generate hazardous wastes in mining, oil refining, pesticide manufacturing, and other chemical productions.

Water contamination

It occurs when foreign substances are introduced into the water, such as chemicals, sewage, pesticides and fertilizers from agricultural spillways, or metals such as lead or mercury.

Water pollution can seriously affect marine life. For example, sewage causes pathogens to grow. On the other hand, organic and inorganic compounds in water can change its composition.

Most polluting types of factories

Animal production

Animal production factories are used to produce meat or dairy products in large quantities.

They produce a huge amount of waste, such as blood, feces, and pesticides, causing a great deal of air, land, and water pollution.

These factories produce gases such as methane and ammonia, which lower the quality of the air and are harmful to health.

Excess animal feces and fertilizers can alter the natural level of nutrients in the water. This causes a decrease in the level of oxygen, dissolved by the excessive growth of decomposers, causing the death of fish.

Agricultural pesticides also end up in the soil, water, and air, and can be toxic to living things with which they come in contact.

Metal melting

Metal foundries that process and refine minerals and scrap create silica and metal powders during their initial crushing.

Heating and smelting processes produce emissions of sulfur and carbon oxides. Cast aluminum can emit arsenic particles. On the other hand, the refining of lead and gold produces emissions of mercury and cyanide.

Food processing

Food processing factories use a wide range of methods for the preparation, cooking and packaging of food products. With these methods they release particles into the atmosphere.

The handling of bulk material such as grains and flour produces dust. The frying and smoking processes release soot into the air. Processing and washing in meat and fish processing plants produces volumes of liquid waste that leave behind mold and bacterial residues that also pollute the air.

Electronic products

The popularity of cell phones and mass-produced electronics has increased the amount of heavy metals in the environment.

Heavy metals like lead, mercury, and arsenic enter the environment during factory production. In the same way they do it when a consumer discards them.

Textile factories

Textile factories are second only to agriculture in the amount of pollution they generate and the large amounts of water they use.

The toxic chemicals used to create textiles are the main sources of contamination from textile mill operations.

Factories use polyvinyl chloride to classify fabrics, chlorine bleach to lighten the color of the fabric. On the other hand, benzidine and toluidine as dyeing agents, which are carcinogens.

Other toxic chemicals used are formaldehyde, lead, and mercury. Fabrics are continuously washed as they move through the production line. The release of this chemical mixture from wastewater can contaminate waterways.
