Plastic Production: An Annual Concern For Washington Post Readers

Plastic is a versatile and affordable material used in a wide range of applications, from food packaging to medical instruments. However, the world's annual plastic production has become an environmental concern, with an estimated 350 to 460 million tons of plastic waste generated each year. While the United States has a low rate of burning plastic due to its waste disposal system, other countries like India, Indonesia, and Russia have been noted for their open burning of plastic, contributing to air pollution and health issues. The crisis in the recycling industry and the mismanagement of plastic waste, particularly in low-to-middle-income countries, further exacerbate the problem.

Plastic burning and health risks

Plastic burning has been linked to a range of health risks, and it is a significant issue globally, with a recent study showing that a large proportion of the world's plastic waste is burned in the open air. This is particularly prevalent in several countries in the Global South, with India, Indonesia, and Russia being among the top five contributors. The open burning of plastic generates fine particulate pollution, contributing to approximately 7 million deaths annually. It also releases toxic chemicals, such as carbon monoxide and hydrogen cyanide, which have severe health implications, including cancer, birth defects, and respiratory and neurological issues.

The toxic chemicals released from plastic burning can cause both immediate and long-term health problems. Short-term exposure to the fumes from burning plastic can lead to respiratory issues, eye and skin irritation, and headaches. Long-term exposure to these toxic chemicals has been linked to more severe health issues, including various types of cancer, heart disease, endocrine disruption, thyroid problems, and reproductive system complications.

In addition to the direct health risks of plastic burning, there are also indirect consequences. The fine particulate matter and toxic chemicals released into the atmosphere can contaminate the air, water, and soil, leading to environmental degradation. This pollution can have a detrimental impact on ecosystems, particularly marine life, and can also affect agricultural productivity and food security.

Furthermore, plastic burning contributes to climate change, which is recognized as a significant threat to human health. The emissions from plastic burning add to greenhouse gas concentrations, leading to global warming and associated health risks, such as heat stress and the increased incidence of mosquito-borne illnesses.

The health risks associated with plastic burning highlight the urgency of improving waste management practices and reducing plastic pollution. It is crucial to develop sustainable alternatives to plastic, implement effective recycling programs, and promote global cooperation to address this pressing issue.

Plastic production and waste

Plastic is a rapidly growing segment of municipal solid waste (MSW). The world produces around 350 million tons of plastic waste each year, with some estimates reaching 450 million tons. The annual production of plastics has increased nearly 230-fold since 1950, when only two million tons were produced. The proliferation of plastic products has been extraordinary, with humans producing more plastic in the last ten years than during the whole of the last century.

Plastic is a versatile and affordable material used in various applications, including construction, home appliances, medical instruments, and food packaging. However, when plastic waste is not properly managed—through recycling, incineration, or sealed landfill disposal—it becomes an environmental pollutant. It is estimated that one to two million tons of plastic enter our oceans each year, affecting wildlife and ecosystems.

The United States, a top producer of plastic waste, has a low rate of burning plastic due to its waste disposal system. However, the country's recycling industry is in crisis, with a large volume of trash making the cost of separation financially unviable. As a result, recyclable materials often end up in landfills, with only about a third of the country's waste being recycled or composted.

Open burning of plastic has been linked to various health issues, including heart disease, respiratory disorders, and neurological problems. It releases fine particulate pollution, which causes approximately seven million deaths annually, as well as toxic chemicals that contribute to cancer, birth defects, and lung issues.

To address the issue of plastic pollution, it is crucial to improve waste management practices, especially in low-to-middle-income countries where most ocean plastics originate due to poorer waste management infrastructure. While reducing plastic production is important, improving waste management can have a more significant impact on reducing plastic pollution.

Plastic recycling crisis

The world produces around 250 million tons of plastic waste in municipalities in a year. Plastic bottles, cigarette butts, plastic packaging, and other plastic products contribute to this waste. While some of it is recycled, a large proportion of plastic waste is burned in the open air or put into landfills.

The plastic recycling industry is in crisis. The cost of separating junk from recyclables is making the business financially unviable. In 2017, only 8.4% of the plastic used in the United States was recycled. The crisis worsened when China stopped accepting foreign recyclables in 2018, leading to a reduction or cessation of recycling services in hundreds of cities. As a result, a significant amount of recyclable material ends up in landfills.

Chemical-based ways of recycling plastic have been proposed as a solution to the crisis. However, there are concerns that these methods may not significantly increase recycling rates and could pose risks to human health and the environment. Mechanical ways of recycling plastic involve the sorting, chopping, and grinding of waste products, but plastic is harder to sort than ever due to the increasing number of plastic varieties and the lower cost of producing new plastic from oil.

The focus should be on reducing overall single-use plastic consumption and scaling up reuse, rather than solely relying on recycling as a solution to the plastic crisis.

Plastic in the ocean

According to a study published in the PLOS One journal, there are more than 170 trillion pieces of plastic in the world's oceans, weighing around 2.4 million metric tons. This plastic smog, as researchers call it, is doubling in size about every six years. If this trend continues, the amount of plastic in the ocean will outweigh fish pound for pound by 2050.

The plastic pollution in the ocean is not limited to microplastics. Large pieces of plastic waste also wash up on beaches and remote islands, transported across long distances by wind, rivers, or wastewater outflows. The Great Pacific Garbage Patch is one such example, where plastics float slightly below the surface in one of the world's five major gyres, or current systems.

Addressing the issue of plastic in the ocean requires a multifaceted approach. While recycling is important, it is not a feasible solution on its own due to the volume of plastic waste generated and the challenges in the recycling industry. Instead, a combination of improved waste management, incentives for waste collection and recycling, more efficient packaging, and better infrastructure to prevent plastic from entering waterways is necessary.

Plastic waste management

One of the primary challenges in plastic waste management is the low recycling rate. Despite recycling efforts, only about a third of the trash generated in 2017 was recycled or composted, with similar rates in subsequent years. The recycling industry faces financial viability issues due to the high cost of separating recyclables from non-recyclables. Additionally, the cessation of recyclable imports by China in 2018 exacerbated the crisis, leading to a reduction or cessation of recycling services in hundreds of cities.

To improve plastic waste management, a range of strategies must be employed. Firstly, Extended Producer Responsibility (EPR) policies can be implemented, holding producers accountable for the entire life cycle of their products, including proper disposal and recycling. Deposit Return Systems (DRS) can also be introduced, incentivizing consumers to return plastic products for recycling or reuse. Secondly, the informal "waste picker" sector should be recognized and supported. These individuals play a crucial role in waste management, particularly in developing countries, by collecting and sorting recyclable materials.

Additionally, it is essential to focus on reducing plastic waste generation in the first place. This can be achieved by promoting reusable alternatives, such as cloth bags instead of plastic bags, and encouraging consumers to refuse single-use plastics whenever possible. Education and awareness campaigns can play a vital role in empowering individuals to make more sustainable choices and understand the importance of proper waste management.

While there is no one-size-fits-all solution, a combination of regulatory policies, infrastructural improvements, and behavioral changes is necessary to address the complex issue of plastic waste management effectively. By working together and prioritizing sustainable practices, we can reduce the environmental and health impacts of plastic pollution.
