PLASTIC POLLUTION – ENVIRONMENT

News: How plastics affect our daily life

 

What's in the news?

       Two papers published in Nature have found evidence for widespread plastic contamination of coral reefs and freshwater lakes.

       The reef study finds that larger fragments (mostly debris from the fishing industry) make up most of the plastic found and these macro plastics are especially abundant in deep reefs.

       The assessment of freshwater lakes and reservoirs reveals that all assessed bodies of water were contaminated with microplastics.

 

Key takeaways:

       According to UN data, more than 400 million tonnes of plastic is produced every year worldwide, half of which is designed to be used only once.

       Of that, less than 10 per cent is recycled. Consequently, an estimated 19-23 million tonnes end up in lakes, rivers and seas annually.

       Around the world, one million plastic bottles are purchased every minute, while up to five trillion plastic bags are used worldwide every year.

       In total, half of all plastic produced is designed for single-use purposes – used just once and then thrown away.

 

Plastic pollution:

       It includes plastic waste that is mismanaged (e.g. open-burned and dumped in uncontrolled dumpsites) and leakage and accumulation of plastic objects and particles that can adversely affect humans and the living and non-living environment.

 

Issues of Plastic Pollution:

1. Slow decomposition rate:

       Plastics are hard to eradicate due to their slow decomposition rate in natural ecosystems.

2. Microplastics:

       Plastics break down into their smaller units called microplastics – officially defined as plastics less than five millimetres in diameter.

       These microplastics find their way across the planet, from the depths of the Pacific Ocean to the heights of the Himalayas.

       According to the most recent global estimates, an average human consumes at least 50,000 microplastic particles annually due to contamination of the food chain, potable water, and air.

3. Effect on Human Health:

       Microplastics contain a number of toxic chemicals which pose severe risks to human health. The biggest health risk associated is with the chemical BPA or Bisphenol A , which is used to harden the plastic.

       BPA contaminates food and drinks, causing alterations in liver function, insulin resistance, foetal development in pregnant women, the reproductive system and brain function.

4. Marine pollution:

       The largest collection of plastics and microplastics in the ocean is in the Great Pacific Garbage Patch – a collection of marine debris in the North Pacific Ocean. Also known as the trash vortex, it is located between California and Japan, and formed due to converging ocean currents.

       As per estimates, the GPGP covers a surface area of 1.6 million sq.km– roughly half the size of India! There are other, smaller such garbage patches in other oceans.

       It floats on the sea surface and ends up clogging the marine animals.

5. Plastisphere:

       Plastics are becoming part of the Earth’s fossil record and a marker of the Anthropocene, our current geological era. They have even given their name to a new marine microbial habitat called the “plastisphere”.

6. Climate change:

       Plastic, which is a petroleum product, also contributes to global warming. If plastic waste is incinerated, it releases toxic fumes and carbon dioxide into the atmosphere, thereby increasing carbon emissions.

7. Tourism and Economy:

       Plastic waste damages the aesthetic value of tourist destinations, leading to decreased tourism-related incomes and major economic costs related to the cleaning and maintenance of the sites.

 

Global Initiatives to Tackle Plastic Pollution:

1. The 1972 Convention on the Prevention of Marine Pollution by Dumping Wastes and Other Matter (or the London Convention)

2. The 1996 Protocol to the London Convention (the London Protocol)

3. The 1978 Protocol to the International Convention for the Prevention of Pollution from Ships (MARPOL).

4. The United Nations Environment Program (UNEP) considers plastic marine debris and its ability to transport harmful substances as one of the main emerging issues affecting the environment.

5. Glo Litter Partnerships (GLP) - It is a project launched by the International Maritime Organization (IMO) and the Food and Agriculture Organization of the United Nations (FAO) and initial funding from the Government of Norway.

6. Clean Seas Campaign:

       The United Nations Environment Programme launched the Clean Seas Campaign in 2017

       Aim:  The goal was to galvanize a global movement to turn the tide on plastic by reducing the use of unnecessary, avoidable and problematic plastics including single-use plastics and phasing out intentionally added microplastics.

7. Greenpeace - It is an environmental NGO that is dedicated to conserving the oceans and marine life across the globe. Its grassroots efforts have resulted in the ban of destructive fishing practices, companies changing their fishing policies, and the creation of whale sanctuaries.

8. United Nations resolution - 124 countries which are party to the United Nations Environment Assembly including India signed a resolution to draw up an agreement which will in the future make it legally binding for the signatories to address the full life of plastics from production to disposal, to end plastic pollution.

 

Indian Initiatives to Tackle Plastic Pollution:

1. Ban on single-use plastics:

       India has banned the production, use and sale of single-use plastics such as bags, cups, plates, cutlery and straws in many states.

2. Extended Producer Responsibility (EPR):

       The Indian government has implemented EPR, making plastic manufacturers responsible for managing and disposing of the waste generated by their products.

3. Plastic Waste Management Rules:

       India introduced the Plastic Waste Management Rules in 2016, which provide a framework for managing plastic waste through various measures, including recycling and waste-to-energy initiatives.

4. Plastic Waste Management (Amendment) Rules, 2022:

       The guidelines on EPR (Extended Producer Responsibility) coupled with the prohibition of identified single-use plastic items.

       It banned the manufacture, import, stocking, distribution, sale and use of carry bags made of virgin or recycled plastic less than seventy-five micrometers.

5. Swachh Bharat Abhiyan:

       The Indian government launched the Swachh Bharat Abhiyan, a national cleanliness campaign, which includes the collection and disposal of plastic waste.

6. Plastic Parks:

       India has set up Plastic Parks, which are specialized industrial zones for recycling and processing plastic waste.

7. Beach clean-up drives:

       The Indian government and various non-governmental organizations have organized beach clean-up drives to collect and dispose of plastic waste from beaches.

8. Awareness campaigns:

       India has launched awareness campaigns to educate people about the harmful effects of plastic pollution and encourage them to use sustainable alternatives.

9. The “India Plastic Challenge – Hackathon 2021":

       It is a unique competition calling upon start-ups /entrepreneurs and students of Higher Education Institutions (HEIs) to develop innovative solutions to mitigate plastic pollution and develop alternatives to single-use plastics.

 

WAY FORWARD:

       Global plastic production must be capped and reduced to prevent plastic pollution from tripling by 2040.

       Adopt a circular economy approach for tackling the problem of plastic pollution.

       Circular economy solutions can reduce pollution by 80% by 2040.

       Financial mechanisms and capacity-building are essential for participation and national legislation implementation.

       Ensure Accountability - Governments and businesses must be held accountable through mandatory disclosure and reporting.

       Global North countries that export their waste to Global South countries must be held accountable for supporting infrastructure development in importing countries by at least the volume they export annually.

       Strengthen Waste Management Infrastructure - Financial support is required to invest in robust waste collection and recycling infrastructure across cities and towns.

       Implement effective segregation systems, establish recycling centers, and promote the adoption of advanced technologies for plastic waste processing.

       This can involve collaboration between the government, private sector, and civil society to develop innovative solutions.

       Investing in waste-to-energy plants using advanced technologies can reduce fossil fuel dependence and generate electricity while effectively managing plastic waste.

       India has the capacity to process 14.2 million tonnes of plastic waste annually, accounting for 71% of primary plastic production.

 

Plastic pollution is perhaps the biggest threat facing the planet after climate change. Government ministries at the national and local levels must collaborate in the development, implementation and oversight of policies, which includes participation from industrial firms, non-governmental organisations and volunteer organisations to reduce the impacts of plastic pollution.
