Blue Category of Industries

Source:  DTE

Context: The Central Pollution Control Board (CPCB) has introduced a new ‘Blue Category’ of industries under Essential Environmental Services (EES), controversially including Waste-to-Energy (WTE) incinerators, previously classified as highly polluting Red Category industries.

About Blue Category of Industries:

  • What is the Blue Category of Industries?
    • The Blue Category was introduced by the CPCB to classify sectors that are essential for environmental management but are relatively low on pollution—however, this has sparked debate.
  • Key Features of Blue Category Industries:
    • Recognized as part of Essential Environmental Services (EES).
    • Granted extended validity of ‘Consent to Operate’ (CTO)—up to 2 years.
    • Intended for projects that produce minimal hazardous waste.
    • Expected to align with circular economy goals.
  • Industries Included: Sewage Treatment Plants (STPs), Composting units, Biogas plants, Material Recovery Facilities (MRFs), and Waste-to-Energy (WTE) incinerators.
  • Colour-Based Industrial Classification Methodology:

The MoEFCC, in collaboration with CPCB, introduced colour-coded industrial categorisation to guide zoning, surveillance, and pollution control.

  • Classification Basis:
    • Pollution Index (PI): Ranges from 0 to 100
      • PI 0–20: White (least polluting)
      • PI 21–40: Green
      • PI 41–59: Orange
      • PI 60–100: Red (most polluting)
  • Establishment:
    • Launched under the ‘Re-categorization of Industries’ framework in 2016.
    • Empowered by the Environment (Protection) Act, 1986.
    • CPCB and State Pollution Control Boards (SPCBs) have authority to classify industries.
  • Procedural Criteria for Blue Category Inclusion:
    • No generation of hazardous waste or toxic emissions.
    • Must promote circular economy (reuse, recycle, resource efficiency).
    • Must align with Sustainable Waste Management Rules, 2016.
