What Are the Most Polluting Industries?

Despite what some global leaders may say and think, the world is in danger. Pollution levels are at an all time high and governments are not doing enough to limit the amount of carbon that is being emitted into the atmosphere. Pure Earth, a non-profit organisation that is dedicated to fighting pollution, released a list a few years ago of the most polluting industries in the world.
Here is what its study brought to light.

10. Dyeing

The dye industry was placed at number ten on the list. Dyes can be found in all manner of products, including plastics, paper, textiles, paint etc. Artificial dyes are often used instead of more expensive and less durable natural dyes, and contain a range of hazardous chemicals that are harmful to humans and the environment.

9. Product Manufacturing

The manufacturing of consumer goods contributes a lot of pollution to the atmosphere. Factories use a range of dangerous chemicals and their waste disposal methods are often not monitored sufficiently stringently.

8. Chemical Manufacturing

‘Chemicals’ encompasses a broad range of products, from petrochemicals to pharmaceuticals and explosives. Waste products of this manufacturing often include toxic chemicals that cause environmental contamination and degradation of human health to those that live near the factories.

7. Industrial Estates

Industrial estates are areas designated for industrial activities, such as plants, warehouses and infrastructure facilities. While these estates are usually a safe distance for residential zones, compliance with contamination regulations is not always of the highest quality and seepages of chemicals are known to happen.

6. Industrial Dumpsites

Is there anything more depressing than seeing trash piled up at a landfill? The mishandling of waste products, including hazardous substances causes serious detriment to the surrounding environment and health of local residents.

5. Artisanal and Small Scale Gold Mining

When small scale gold mining operations occur, they often lack the funding needed to use state of the art extraction technology. Thus, more primitive methods are used. These methods increase the chance of toxic wastes, such as mercury, being generated and irresponsibly disposed of.

4. Tanneries

The tanning process involves transforming raw animal hides into leather for use in a variety of consumer products. Pure Earth, during its research, uncovered over 100 toxic tanning sites that do not have appropriate waste management systems in place for the dangerous chemicals tanning produces.

3. Lead Smelting

Lead smelting is when pure lead is extracted from its ore. While important, the process creates substantial waste in the form of solid waste, air-borne waste and wastewater. These toxic substances are released into the atmosphere and can have far-reaching effects on the health of humans and the planet.

2. Mining and Ore Processing

It probably won’t surprise you to see mining near the top of this list. Mining has come under fire by a number of green activist groups because of the enormous amount of waste produced from the industry. Around 7 million people across the globe are in danger health-wise because of irresponsible mining practices.

1. Used Lead-Acid Batteries

Finally we come to the main culprit of industrial pollution: used lead-acid batteries. Lead-acid batteries are most commonly used in vehicles and although they are rechargeable, eventually they lose their ability to hold any electrical charge. These batteries then become highly hazardous waste and are often poorly dealt with, leading to contamination of nearby air and water.

The largest solar farms in the world

Image
Solar energy is gaining in popularity. Most people know solar power as the rooftop panels that are being installed on more and more houses; or projects like Elon Musk’s Solar Roof. However, there are many different applications for solar and many ways energy can be generated using the power of the sun. Electricity is the most common use, but solar energy can also be used to heat water for use in the home, or a swimming pool, etc. Solar arrays can also be used to redirect the beams of the sun to a central point which is then converted to heat energy to drive turbines, much like a coal plant would use a burner – only this time there are no emissions, and just clean energy. A large array of solar panels, be it photovoltaic or thermal, is called a solar farm. Here we take a look at a few of the biggest in the world. Tengger Desert Solar Park Located in China, the world’s largest solar farm uses solar PV panels to generate 1,500MW of electricity. This plant covers 43 square kil

Building Smart Cities, an Energy Transition

Image
Smart cities were once thought to have been a $1.6 trillion market by 2020. Everything from housing, transportation, urban planning, management, would contribute to a smarter neighbourhood enriching the lives of the citizens and residents. From self-driving cars to automated delivery drones, IT networks will become the backbone of the interconnected world. We are not there, yet. Technology is developing and evolving but there is a lack of a common direction, and funding, for many of the players in the market bridging that final implementation gap. Often overlooked by the general public in their desire for a smarter city is also the technical feasibility. Not only do information networks play an important part; but energy is the driver of all of our smart ambitions. To foster the growth of smart cities and to facilitate the transition we must also critically evaluate our energy production and consumption pattern. On a local scale, Electric Vehicles are gaining in popularity

The World’s Longest Transmission Lines

Image
Some of the world’s largest power plants are in some of the most remote locations compared to where the electricity they generate is consumed. The technology of choice for many of these lines is HVDC or High Voltage Direct Current, which allows the electricity generated to be supplied up to hundreds of kilometers away. As the technology is not inexpensive, and requires a stable reliable generation supply in order to be effective. With increasing power demands and strain on electricity systems , developing High, and Ultra High Voltage power lines is only set to increase as new generation projects come online. As population centers are usually located far from hydro-electric plants, it is no surprise that most of the long-distance projects supply power from these dams to large population centers. Rio Madeira transmission link, Brazil Coming in at 2,385km, the Rio Madeira Transmission Link in Brazil tops the chart as the world’s longest. Supplying power from the Santo Antônio an
