5 Ways Factories Cause Pollution & Harm Environment
If you are wondering after reading the title of this article, “well, factories are essential for economy and industry, what are you saying?” then rest assured, the article isn’t about the importance of factories or lack thereof, it is about the pollution they cause and how best to minimize that.
There has been a great debate for the last few decades over the phenomenon of global warming itself the effects it has on the atmosphere. The key note to take from it is that there is a way to lessen the wholesale temperature rise by being more careful as a society and on a personal level.
In this article, we will be discussing the five main ways factories are causing air, water and noise pollution which is ending up harming the environment. The best way to avoid that is to invest in energy efficient cooling and heating systems.
Burning Fossil Fuels for Energy
By far the biggest reason for global warming and factories are in no way the only culprit in this. Vehicles, ammunition and military gear, as well as power generation units are only culpable in this. However, the industries and factories’ share in some of the biggest, less than power generating units to be fair. When coal or gas is burned to create energy, it release dangerous pollutants in the air, including gases and metal fumes, some of them are nitrogen, lead, arsenic, different oxides and hydrogen fluorides and chlorides.
Burning natural gas not only produces less pollutants compared to coal but also produces it in less quantity.
Petrochemical smog is created when the pollutant compounds like nitrogen oxides, which are dispersed in the air from the processes of heating, cooling, painting and cleaning, react with other volatile organic compounds in the sunlight. The sunlight is the most important factor in this phenomenon happening. Apparently, this petrochemical smog looks like a brown hazy clod which can linger in the atmosphere, usually in cities, for weeks.
Smelting of Metals
Metal is used to create different metallic, read vehicles, instruments, machinery, infrastructure, and other things. Sometimes we use ores for it but sometimes base metals are required for specific reasons. The process of produce a base metal out of an ore is called metal smelting. Heating the ores in this process creates carbon and sulfur oxides which are dangerous for the atmosphere. Whereas other pollutants like arsenic, lead, aluminum, mercury and cyanide are also a possibility.
Non-Ideal Waste Disposal
Waste disposal in several countries in the world is not regulated according to the modern standards. There are still places in the world that dump the waste in the rivers or in the ocean because it is easier and cheaper than to invest in proper waste disposal systems. The chemicals and reactive materials in the industrial waste is not only dangerous for the humans but also for the aquatic life.
Similarly, the food processing plants should have a proper mechanism to dispose of the leftovers as most of them end up producing dangerous gases and pollutants in the atmosphere.
