The World's Plastic Weight Problem

Plastic pollution is a pressing issue that affects the entire world. The world generates approximately 400 million tonnes of plastic waste each year, with a significant amount ending up in our natural environment and landfills. This plastic waste comes from various sources, including disposable products such as diapers, trash bags, cups, utensils, and packaging materials. While plastic has added value to our lives due to its cheap, versatile, and sterile nature, its mismanagement contributes to environmental pollution. The impact of plastic pollution is far-reaching, with marine animals ingesting or becoming entangled in plastic waste, and microplastics making their way into our food and water systems.

Plastic pollution in the ocean

The accumulation of plastic in the ocean has severe consequences for marine wildlife. Animals, including seabirds, sea turtles, seals, and other marine mammals, often ingest plastic or become entangled in it, leading to thousands of fatalities each year. The problem extends beyond the initial ingestion, as the plastic travels up the food chain, eventually reaching humans. According to a 2019 Reuters infographic, humans ingest about five grams of plastic every week, amounting to a full dinner plate's worth of plastic in a year.

The sources of plastic pollution in the ocean are diverse. A significant contributor is nonpoint source pollution, resulting from runoff from human activities along coastlines and far inland. This includes runoff from septic tanks, vehicles, farms, livestock ranches, and timber harvest areas. Additionally, a 2017 study estimated that Asian countries contributed 86% of plastic emissions to the ocean. Furthermore, the management of plastic waste is crucial in preventing ocean pollution. Improper waste management, such as failing to recycle, incinerate, or dispose of plastic in sealed landfills, increases the risk of plastic leaking into rivers, lakes, and the ocean.

To address the issue of plastic pollution in the ocean, a multifaceted approach is necessary. Firstly, improving waste management practices globally, especially in low-to-middle-income countries, is essential. This includes implementing domestic policies and foreign investments in waste management infrastructure. Secondly, reducing the production of virgin plastic and investing in recyclable plastics can significantly curb plastic pollution. Additionally, intercepting plastic in rivers before it reaches the ocean is a crucial strategy, as rivers are a significant source of ocean plastic pollution. Organizations like The Ocean Cleanup are actively working towards this goal, aiming to remove 90% of floating ocean plastic by 2040 through river interception technologies and ocean cleanup systems.

In conclusion, plastic pollution in the ocean is a critical issue that demands immediate attention. By improving waste management, reducing plastic production, and investing in river interception and cleanup technologies, we can significantly reduce the devastating impact of plastic on our oceans, marine life, and ecosystems.

Plastic waste in landfills

Plastic is a cheap, versatile, and sterile material used in various applications, including construction, home appliances, medical instruments, and food packaging. The world produces over 450 million tonnes of plastic annually, with a sharp increase in production over the last 70 years. Unfortunately, the disposal and management of plastic waste have not kept pace with its production, resulting in significant environmental and health risks.

Microplastics, formed through the breakdown of larger plastic debris, are invisible to the human eye and can be ingested by marine animals, eventually making their way up the food chain to humans. According to a 2019 Reuters infographic, humans ingest about five grams of plastic every week, equivalent to a full dinner plate's worth of plastic in a year. The presence of MPs in the environment further exacerbates health risks by leading to the accumulation of non-biodegradable pollutants.

To address the issue of plastic waste in landfills, improved waste management practices and policies are urgently needed. This includes promoting the circular economy concept, where waste is minimized through reuse and recycling. While microbial degradation and controlled contaminant release landfills are potential solutions, the best option is to limit plastic use through substitution or reuse, followed by separate collection and recycling. Partnerships between companies and recycling facilities can also help establish reliable plastic supply chains for recycling and repurposing.

Plastic recycling rates

The low recycling rates of plastic are concerning given the sharp increase in plastic production over the last 70 years. In 1950, the world produced just two million tonnes of plastic, compared to over 450 million tonnes today. This mass production of plastic has resulted in a significant amount of plastic waste, with the world now generating approximately 400 million tonnes of plastic waste each year.

While the recycling rates of some specific types of plastic containers are more significant, such as PET bottles and jars, which had a recycling rate of 29.1% in 2018, the overall recycling rate of plastic remains relatively small. In 2018, the United States generated 35.7 million tons of plastic, with only 3 million tons recycled, resulting in 27 million tons of plastic being sent to landfills.

The low recycling rates of plastic are due in part to the challenges associated with recycling plastic compared to other materials. Plastic recycling has always struggled, never reaching above 10% even when millions of tons of plastic waste per year were exported to China. Additionally, the per capita generation of plastic waste has increased by 263% since 1980, further contributing to the low recycling rates.

To address the issue of low plastic recycling rates, it is crucial to improve waste management strategies, particularly in low-to-middle-income countries, where most ocean plastic originates. This includes reducing the growth of virgin plastic production, improving waste collection systems, and investing in recyclable plastics.

Plastic production by country

Plastic production and consumption have had a devastating impact on the environment, with plastic waste wreaking havoc on the soil, water, animals, and people's health. While several countries have made significant progress in reducing plastic waste, it is still a pressing issue. Here is a detailed overview of plastic production by country:

China:

China is the biggest exporter and the largest producer of plastic raw materials, contributing 32% of global plastic raw materials sourcing in 2021. The country's most in-demand plastic types are Polyethylene (PE), Polypropylene (PP), and Polystyrene (PS). Despite being one of the largest overall producers of plastic waste, China has taken steps to reduce single-use plastics, and its per capita production of plastic waste was one of the lowest in the world in 2016.

United States:

The United States is the second-largest producer of plastics and their products. It contributed around USD 15.4 billion, or 21% of the global plastic industry market share in 2019. The country has regional plastic production hubs in states like Louisiana, Texas, and Ohio. However, the U.S. has faced a decline in plastic recycling, and it burns about six times more plastic waste than it recycles, contributing to greenhouse gas emissions.

Germany:

Germany is the third-largest plastic producer, holding the top spot in the European Union. It produced 14.48 million tons of plastic waste in 2010, but by 2016, the country had reduced its plastic waste creation to 6.68 million tons. Germany's Environment Ministry introduced a five-point plan in 2018 to further curb plastic waste.

Other Countries:

Several other countries are notable plastic producers and exporters, including Italy, France, Canada, the United Kingdom, and Brazil. Indonesia, the Philippines, Vietnam, Sri Lanka, Thailand, Egypt, Malaysia, Nigeria, and Bangladesh are also among the top plastic waste-producing nations. While some countries have implemented bans on single-use plastic bags, others like Norway and Germany have excelled in recycling programs, providing models for effective waste management.

Plastic consumption by humans

Plastic is a relatively new invention, with the first commercially available plastic product launched in 1907, and mass production starting in 1952. However, its versatility and low production cost have made it one of the most widely used materials today. Plastic is used in a wide range of applications, including food packaging, healthcare, construction materials, furniture, and textiles.

The global consumption of plastic is accelerating, with over half of the plastic ever manufactured produced since 2000. The average annual plastic consumption in Western Europe is around 150 kg per person, more than twice the global average of 60 kg. The United States is the world's biggest contributor to plastic pollution, generating about 42 million metric tons of plastic waste annually, amounting to 130 kg per person.

Human consumption of plastic occurs through the ingestion of microplastics, which are small plastic particles that are invisible to the human eye. Microplastics are found in commonly consumed foods, drinking water, and even the air we breathe. According to a 2019 Reuters infographic, humans ingest about five grams of plastic every week, which is equivalent to a spoonful or half a rice bowl. In a year, this amounts to a full dinner plate of plastic.

The exposure risk of microplastics to humans is still being studied, but it is estimated that individuals who meet their recommended water intake through bottled sources may ingest up to 90,000 microplastics annually, compared to 4,000 microplastics for those who consume tap water. The average person is estimated to consume between 78,000 and 211,000 microplastic particles annually through food, drink, and inhalation, with bottled water being the biggest source.

To reduce plastic consumption and pollution, it is important to improve waste management practices, such as recycling and incineration, and invest in recyclable plastics. The EU's Zero Pollution Action Plan aims to reduce plastic litter at sea and microplastics released into the environment. By improving waste management and reducing plastic production, we can significantly reduce plastic pollution.
