E.8. Plastic Pollution

  • The marine ecosystem spans approximately 70% of the Earth’s surface, making it an essential component of the planet’s biosphere. 
  • Out of the nearly 1.5 million documented species, around 250,000 are found in oceanic environments. 
  • Remarkably, nearly half of the world’s primary production takes place in the sunlit surface layers of the sea.
  • Seafood constitutes 20% of the world’s protein in global diets.
  • The health of the marine food web and fisheries relies on the long-term viability of autotrophic algae (phytoplankton) and zooplankton.
  • Plastic pollution is a significant contemporary threat to the marine environment.
  • Increased plastic use leads to negative environmental impacts.
  • Plastic pollution can interfere with plankton species, affecting the foundation of the food web.
  • Adverse effects on other organisms disrupt the delicate balance in the marine ecosystem.

Important Topics 

Details

Plastics as a Waste Material in the Marine Environment

  • Annual estimation of plastic waste introduced into the marine environment is unavailable.
  • Plastic waste primarily results from fishing-related activities and non-point source influx from beaches.
  • Differences in the fate of plastics in the ocean environment compared to on land: a) UV-induced photo-oxidative degradation is slower at sea. b) Lack of easy retrieval, sorting, and recycling mechanisms for plastic waste in the ocean.
  • Extended lifetimes for plastics at sea due to these factors.
  • Accumulation of plastic waste in the world’s oceans, with potential disintegration into microparticulate debris.
  • Impact of microparticles on Antarctic krill and zooplankton, with ingestion rates dependent on particle concentration.

Impact of Plastics in the Marine Environment

  • Plastics are bio-inert, not conventionally toxic, but can concentrate toxic and non-toxic organic compounds from seawater.
  • Plastic-related distress is documented in over 250 species worldwide, particularly focused on larger surface water and beach species.
  • Negligible research by government agencies or the plastics industry on plastic issues in the marine environment.

Plastics as a Waste Material in Land Environment

  • Problems with uncollected plastic waste, include choking of drains, illness in animals, and non-biodegradable nature.
  • The presence of additives and chemicals in plastics poses health and groundwater pollution risks.
  • Plastic Waste Management Rules, 2016: 15,000 tonnes of plastic waste generated daily, with 6,000 tonnes uncollected.
  • Lack of an eco-friendly alternative to plastic; the challenge is to improve plastic waste management systems.

Salient Features of Plastic Waste Management Rules, 2016

  • Increase the minimum thickness of plastic carry bags for easier collection and recycling.
  • Promote the use of plastic waste for road construction or energy recovery.
  • Extension of rules to rural areas with responsibility given to Gram Panchayat.
  • Waste generators, including individuals and industries, must segregate and manage plastic waste.
  • Organizers of public events are responsible for waste management from their events.
  • Regulation of plastic sheets for packaging, ensuring proper collection and channelization.
  • Introduction of Extended Producer Responsibility (EPR) for producers and brand owners.
  • State Pollution Control Boards (SPCBs) to regulate plastic bags and packaging.
  • Retailers and street vendors are assigned the responsibility not to provide non-compliant plastic bags.
  • Restriction on the availability of plastic carry bags to registered vendors.

Amendment Rules, 2018

  • Phasing out of Multilayered Plastic (MLP) for non-recyclable, non-energy recoverable, or with no alternative use.
  • The central registration system for producer/importer/brand owner.
  • National registry for producers with a presence in more than two states, state-level registration for smaller producers/brand owners.
  • Omission of explicit pricing of carry bags.

Plastic Waste Management Amendment Rules, 2021

  • Prohibition of manufacture, import, stocking, distribution, sale, and use of certain single-use plastics from 1st July, 20.
  • Increase in thickness of plastic carry bags from fifty microns to seventy-five microns in September 2021 and to one hundred and twenty microns in December 2022.
  • Collection and management of plastic packaging waste through Extended Producer Responsibility (EPR).
  • The legal force is given to guidelines for EPR through Plastic Waste Management Amendment Rules, 2021.
