Why in the News?
The Central Pollution Control Board (CPCB) has recently updated its classification of industries, introducing a new category known as the ‘Blue Category.’
Classification of Industries by CPCB:
- The CPCB classifies industries based on their environmental impact, focusing on air pollution, water pollution, and hazardous waste generation.
- Industries are classified using the Pollution Index (PI), which is calculated by considering air, water, and waste pollution, with equal weight given to each factor.
- PI Categories:
-
- White: PI < 25 (least polluting industries)
- Green: 25 ≤ PI < 55
- Orange: 55 ≤ PI < 80
- Red: PI > 80 (most polluting industries)
- This system helps determine industry locations, inspection norms, and pollution-related health impacts.
- It is regulated by the Ministry of Environment, Forests, and Climate Change (MoEFCC) to improve environmental standards.
- Presently 419 industrial sectors are categorized into Red, Orange, Green, White, and Blue.
About the ‘Blue’ Category (Newly Introduced):
- The Blue Category was introduced for industries providing Essential Environmental Services (EES) like pollution management and waste control.
- It recognizes industries involved in critical environmental management, such as waste-to-energy plants, sewage treatment plants, and landfill management.
- Industries in the Blue category receive a 2-year extension on their consent to operate as an incentive for their role in managing pollution.
- Scope: Includes industries that manage waste from both domestic and industrial sources, such as:
- Waste-to-Energy (WTE) Plants: Now in the Blue category despite their high PI, due to their role in waste energy recovery.
- Compressed Biogas (CBG) Plants: Classified as Blue for their low environmental impact when processing municipal waste and agro residue.
- Sewage Treatment Plants & Landfills: These facilities manage environmental hazards through controlled waste disposal.
- Blue category industries must comply with all environmental norms, and their Pollution Index is still calculated as per the standard formula.
- Industries showing successful management may receive extended operating permits and other incentives.
