Uncovering the Environmental Consequences: A Dive into Industrial Pollution

Industrial pollution refers to the negative environmental impact caused by industrial activities. These activities release various pollutants into the air, water, and soil, leading to environmental degradation.

Here are some key points about industrial pollution and its impact on the environment:

Air Pollution
  • Impact of Undesirable Gases: Air pollution is caused by the presence of a high concentration of undesirable gases such as sulphur dioxide and carbon monoxide.
  • Airborne Particulate Matter: This comprises both solid and liquid particles, such as dust, sprays, mist, and smoke.
  • Smoke: It is a common emission from various sources, including chemical and paper factories, brick kilns, refineries, smelting plants, and the combustion of fossil fuels in both large and small factories that disregard pollution regulations.
  • The Bhopal Gas tragedy: It is a notable example of such an incident.
  • The Widespread Impact: Air pollution has detrimental effects on human health, as well as on animals, plants, buildings, and the overall atmosphere.
Water Pollution
  • Contributions to Water Pollution: Water pollution is caused by organic and inorganic industrial wastes and effluents discharged into rivers.
    • The main culprits in this regard are paper, pulp, chemical, textile and dyeing, petroleum refineries, tanneries and electroplating industries that let out dyes, detergents, acids, salts.
    • Heavy metals like lead and mercury pesticides, fertilisers, synthetic chemicals with carbon, plastics and rubber, etc. discharged into the water bodies.
    • Fly ash, phospho-gypsum and iron and steel slags are the major solid wastes in India.
Thermal Pollution
  • Understanding Thermal Pollution: Thermal pollution of water occurs when hot water from factories and thermal plants is drained into rivers and ponds before cooling.
  • Wastes from nuclear power plants, nuclear and weapon production facilities cause cancers, birth defects and miscarriages.
Noise Pollution
  • Noise pollution not only results in irritation and anger, it can also cause hearing impairment, increased heart rate and blood pressure among other physiological effects.

Industrial pollution poses significant environmental challenges, affecting air, water, and noise levels, necessitating comprehensive solutions for sustainable practices.

Industrial Disaster

  • Accidents and disasters in industries often occur due to technical failures or irresponsible handling of hazardous materials.
  • One of the most devastating industrial disasters in history occurred in Bhopal on December 3, 1984, around 00:30 a.m. This tragic incident was a result of a technological failure when highly poisonous Methyl Isocyanate (MIC) gas, along with Hydrogen Cyanide and other reaction products, leaked from the pesticide factory operated by Union Carbide.
  • The official death toll in 1989 was reported at 3,598 lives lost.
  • However, thousands of survivors still suffer from a range of ailments, including blindness, impaired immune systems, gastrointestinal disorders, and more.

Mitigating Industrial Pollution: Sustainable Practices and Innovations for a Cleaner Environment

Every litre of waste water discharged by our industry pollutes eight times the quantity of freshwater. This industrial pollution can be reduced by following the below suggestions:

  • Water Conservation in Industrial Processes: Minimising water use for processing by reusing and recycling it in two or more successive stages. 
  • Rainwater harvesting to meet water requirements. 
  • Treatment of hot water and effluents before releasing them in rivers and ponds. This can be done in three phases:
    • Primary Treatment: It can be done by mechanical means, which involves screening, grinding, flocculation and sedimentation.
    • Secondary Treatment: It is done by biological process
    • Tertiary Treatment: It can be done  by biological, chemical and physical processes, which involves recycling of wastewater.
  • Legal Imperatives: Overdrawing of groundwater reserves by industry where there is a threat to ground water resources also needs to be regulated legally.

  • Use of Advanced Technologies: Particulate matter in the air can be reduced by fitting smoke stacks to factories with electrostatic precipitators, fabric filters, scrubbers and inertial separators.
  • Transitioning from Coal to Oil : Smoke can be reduced by using oil or gas instead of coal in factories.
  • Innovative Redesign: Machinery can be redesigned to increase energy efficiency and reduce noise

NTPC 

NTPC(National Thermal Power Corporation) is a major power providing corporation in India. It has ISO certification for EMS (Environment Management System) 14001. The corporation has a proactive approach for preserving the natural environment and resources like water, oil and gas and fuels in places where it is setting up power plants. This has been possible through:

  1. Optimum utilisation of equipment adopting latest techniques and upgrading existing equipment.
  2. Minimising waste generation by maximising ash utilisation.
  3. Providing green belts for nurturing ecological balance and addressing the question of special purpose vehicles for afforestation.
  4. Reducing environmental pollution through ash pond management, ash water recycling system and liquid waste management.
  5. Ecological monitoring, reviews and online database management for all its power stations.

Conclusion

  • The various industries in India encompass a wide spectrum, from traditional and labour-intensive sectors to high-tech and rapidly advancing ones. 
  • These industries are distributed across the country, each with its unique characteristics and significance. They contribute significantly to the nation’s economy, job creation, and technological advancement. 
  • However, they also bring challenges, such as environmental concerns related to industrial pollution, which necessitate responsible and sustainable practices. 
  • As India continues to evolve and diversify its industrial landscape, finding a balance between economic growth and environmental stewardship, particularly in addressing issues of industrial pollution, will be critical for its future prosperity.

Glossary

  • Mechanisation: The mechanisation approach involves the utilisation of devices to perform tasks. Automation represents the evolved phase of mechanisation, where human cognitive input is not required in the manufacturing process.
  • Agglomeration: Many industries benefit from nearness to a leader-industry and other industries. These benefits are termed as agglomeration economies. 
  • Foot-loose Industries: These are not dependent on any specific raw material such as weight losing or otherwise, but mainly depend on component parts which can be obtained anywhere. They produce in small quantities and also employ a small labour force.
  • Cottage Manufacturing: This represents the smallest-scale production unit, where artisans utilise local raw materials and basic tools to create everyday items within their homes, often with the assistance of family members or occasional part-time labour. 
  • Synthetic Fibre: They are fibres made by humans through chemical synthesis, as opposed to natural fibres that are directly derived from living organisms, such as plants (like cotton) or fur from animals.
  • Manufacturing Hubs: The manufacturing hubs idea reflects an emerging consensus among a large number of industry leaders, technology analysts, and economic development professionals that regions are the place to work on technology-based development and that regions need to be anchored by hubs of collaborative R&D where industry can work with academia and government to solve tough problems and foment technology gains. 
  • White-collar Workers: A white-collar worker is a person who performs professional service, desk, managerial, or administrative work. White-collar work may be performed in an office or other administrative setting.
  • Smelting: It is the process in which metals are extracted from their ores by heating beyond the melting point
  • Technopolis: A technologically advanced city, or one heavily involved in mechanised manufacture of goods, especially of microelectronics.
  • Environmental Degradation: Environmental degradation is the deterioration of the environment through depletion of resources such as air, water and soil, and the destruction of ecosystems and the extinction of wildlife. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
