1. Conceptual Framework, Background & Evolution

Plastic pollution represents one of the most pervasive environmental crises in India, with annual plastic waste generation reaching approximately 9.3 million tonnes (~25,000 tonnes per day). Packaging alone accounts for nearly 59% of total plastic consumption, much of it comprising short-lived or single-use plastics (SUPs) and hard-to-recycle multi-layered packaging (MLPs). Out of India's total plastic waste, only a small fraction is formally recycled, while millions of tonnes accumulate in landfills, block urban drainage networks, or leak into marine and riverine ecosystems.

2. Single-Use Plastic (SUP) Ban & Micron Thickness Trajectory

A. Definition of Single-Use Plastics

Single-Use Plastics (SUPs) are defined under the 2021 Amendment as plastic commodities intended to be used once for the same purpose before being disposed of or recycled. These items possess low utility and high littering potential.

B. The 19 Banned Single-Use Plastic Items (Effective July 1, 2022)

The manufacture, import, stocking, distribution, sale, and use of the following 19 single-use plastic commodities, including polystyrene (thermocol) and expanded polystyrene, are strictly prohibited nationwide:

1. Earbuds with plastic sticks
2. Plastic sticks for balloons
3. Plastic flags
4. Candy sticks
5. Ice-cream sticks
6. Polystyrene (thermocol) for decoration
7. Plastic plates
8. Plastic cups
9. Plastic glasses
10. Plastic cutlery (forks, spoons, knives, straws, trays)
11. Wrapping or packing films around sweet boxes
12. Wrapping or packing films around invitation cards
13. Wrapping or packing films around cigarette packets
14. Plastic or PVC banners less than 100 microns
15. Plastic stirrers

3. Extended Producer Responsibility (EPR) & 5 Packaging Categories

The Extended Producer Responsibility (EPR) framework shifts the financial and physical burden of waste management from local municipalities to Producers, Importers, and Brand Owners (PIBOs) and Plastic Waste Processors (PWPs).

THE 5 STATUTORY PLASTIC PACKAGING CATEGORIES

┌───────────────────┬───────────────────┬───────────────────┬───────────────────┬───────────────────┐
│   CATEGORY 1      │   CATEGORY 2      │   CATEGORY 3      │   CATEGORY 4      │   CATEGORY 5      │

└───────────────────┴───────────────────┴───────────────────┴───────────────────┴───────────────────┘

1. Category I — Rigid Plastic Packaging: PET bottles, HDPE containers, rigid drums, and water carboys.
2. Category II — Flexible Plastic Packaging: Single-layer or multilayer plastic sheets, covers, sachets, and carry bags made entirely of plastic.
3. Category III — Multi-Layered Plastic (MLP) Packaging: Packaging containing at least one layer of plastic and at least one layer of non-plastic material (such as aluminum foil, paper, or cardboard).
4. Category IV — Compostable Plastic Packaging: Plastic carry bags and commodities made from plant-based starches that undergo industrial composting under IS/ISO 17088:2021.
5. Category V — Biodegradable Plastic Packaging (Added in 2024): Materials capable of complete degradation by biological processes in natural environments without leaving any persistent microplastics.

A. CPCB Trading Portal & Surplus Certificates

• Digital Registration: All PIBOs operating across states must register on CPCB's centralized online portal. Operating without registration is illegal.
• Certificate Trading: PIBOs fulfill their EPR obligations by purchasing tradable EPR certificates online from registered Plastic Waste Processors (recyclers, waste-to-energy plants, co-processing cement kilns).
• Deficit Carry-Forward: Unfulfilled EPR targets for a given year can be carried forward for up to 3 years, provided at least one-third of the deficit is cleared annually.

4. Mandatory Recycled Content Targets & Traceability (2025–2026 Norms)

MANDATORY RECYCLED PLASTIC CONTENT TRAJECTORY

Category I (Rigid Plastics)     ──► 30% (FY 2025–26)  ──► Escalates to 60% (FY 2028–29 onwards)
Category II (Flexible Plastics)  ──► 10% (FY 2025–26)  ──► Escalates to 20% (FY 2028–29 onwards)
Category III (Multi-Layered)     ──► 5%  (FY 2025–26)  ──► Escalates to 10% (FY 2028–29 onwards)

1. Mandatory Minimum Recycled Content: PIBOs must mandatorily incorporate a prescribed minimum percentage of recycled plastic resin into new packaging materials, helping reduce reliance on virgin petrochemical plastics.
2. Category I Reuse Obligations: Mandates minimum reuse cycles for Category I rigid packaging (e.g., large water carboys must achieve up to 85% reuse in closed-loop supply chains).
3. Digital QR Code & Barcode Traceability: Every plastic packaging unit must carry an indelible barcode or QR code to enable end-to-end digital tracking from manufacturing through retail to final recycling.

5. Microplastics, Bio-Plastics & Mandatory Labeling Standards

• Microplastics Definition: Any solid plastic particle insoluble in water with dimensions between 1 µm and 5 mm (or 1 µm to 1,000 µm for manufactured microbeads). Microplastics bioaccumulate in marine species and human organs (blood, lungs, placenta, liver).
• Biodegradable Plastic Definition (2024 Rule): Materials capable of biological degradation in soil, landfills, or water that leave no microplastics or toxic chemical residues behind.
• Mandatory Labeling Rules:
  • Recycled Content: Packaging containing recycled plastic must bear a label indicating the exact percentage of recycled resin used, conforming to IS 14534:2023.
  • Compostable Plastics: Must be clearly labeled "100% Compostable" with the manufacturer's CPCB registration number and certification under IS/ISO 17088:2021.
