Environmental court investigates impact of single-use bottle caps in India
Key takeaways
- NGT of India reviews petition on the pollution caused by unrecycled single-use PET bottle caps.
- Petition highlights the gap in waste management regulations for detachable packaging parts like bottle lids.
- There is a growing interest in recycling initiatives and bio-based materials as part of India’s efforts to tackle plastic waste.
The National Green Tribunal (NGT), India’s statutory ecological protection body, has taken up a petition investigating the environmental impact of single-use PET bottle lids.
The petition, filed by climate activist Aakash Ranison through an advocacy group, argues that while plastic bottles are covered under existing waste management regulations, bottle caps are often left unrecycled, causing environmental pollution.
“The Applicant has raised a grievance of plastic pollution being caused by the plastic bottle caps used extensively in packaged drinking water and beverage bottles,” says the petition.
The NGT’s cognizance of the petition indicates that the court has recognized the issue as important and will investigate it further. The NGT also sent notice to the Central Pollution Control Board and other respondents, directing them to file affidavits before a hearing that took place on February 26.
Packaging Insights has contacted the NGT for comment.
Tethered caps
India’s Plastic Waste Management Rules were enacted in 2016, with its EPR scheme set to be implemented in phases through 2027-2028. The petition raises the question of whether this regulation effectively accounts for detachable packaging parts, such as bottle caps.
Ranison highlighted that other countries and regions have adopted tethered caps to curb pollution. Tethered caps were introduced under the EU’s Single-Use Plastics Directive in July 2024. The directive mandates that single-use beverage containers of up to three liters must have lids attached.
Last year, KHS equipped its Innocheck TSI closure inspection unit with an AI-based fault detection system to better identify defect-tethered caps during production.
Recently, Chemco Group commissioned a food-grade PET recycling facility in Gujarat, India, to accelerate the country’s transition toward a circular plastics economy. Meanwhile, the country’s rapidly expanding packaging sector is establishing new opportunities for bio-based materials, said industry experts at the European Bioplastics Conference 2025.
