The World's Plastic Production: A Historical Overview

Plastic was first invented in 1907 by Leo Baekeland, who named his product Bakelite. Since then, the world has produced a staggering amount of plastic. In the last 70 years, the annual production of plastics has increased nearly 230-fold, from two million tonnes in 1950 to over 450 million tonnes in recent years. If current trends continue, there may be irreversible consequences, including contributing to climate change and threatening marine life.

Plastic production has increased nearly 230-fold since 1907

Plastic was first invented in 1907 by Leo Baekeland, who named his discovery 'Bakelite'. Bakelite was the first fully synthetic plastic, and Baekeland also coined the term 'plastics'. However, the mass production of plastic only began in the 1950s, and since then, the annual production of plastics has increased by nearly 230-fold. In 1950, the world produced just two million tonnes of plastic, but by 2019, this figure had skyrocketed to 460 million tonnes. This exponential growth in plastic production has had a significant impact on the environment, with plastic waste becoming an increasingly pressing issue.

The proliferation of plastic products has been remarkable, with humans becoming addicted to this nearly indestructible material. Plastic is cheap, versatile, and sterile, making it ideal for a wide range of applications, from construction and home appliances to medical instruments and food packaging. However, the convenience and functionality of plastic come at a cost. Plastic waste that is not properly managed—through recycling, incineration, or sealed landfill storage—becomes an environmental pollutant.

The consequences of plastic pollution are far-reaching and detrimental. Plastic waste contributes to climate change, as it releases greenhouse gases when exposed to heat, raising global temperatures. Additionally, plastic ends up in oceans and other bodies of water, posing a significant threat to marine life and ecosystems. It is estimated that one to two million tonnes of plastic enter our oceans annually, and plastic waste accounts for one million deaths of marine animals each year.

Compounding the issue is the fact that plastic does not biodegrade in any meaningful way. While sunlight can weaken plastic materials over time, causing them to fragment into microplastics, these microplastics continue to persist in the environment. If current production and waste management trends continue, the situation will only worsen. By 2050, it is estimated that approximately 12,000 million metric tons of plastic waste will be in landfills or the natural environment.

Plastic waste in landfills and bodies of water

Since the invention of the first synthetic plastic, Bakelite, in 1907, the world has witnessed a rapid increase in plastic production, with annual production soaring to 450-460 million tonnes in recent years. This surge in production has inevitably led to a corresponding rise in plastic waste, which has become one of the most pressing environmental issues.

Plastic Waste in Landfills

The disposal of plastic waste in landfills is a common practice worldwide. However, this method raises significant environmental and health concerns. Landfills near waterways, a common occurrence, increase the risk of plastic leakage into aquatic ecosystems. As plastic waste degrades, it breaks down into microplastics, which can be transported by air and leachate, contaminating the surrounding environment. This degradation process can also release harmful volatile organic compounds (VOCs) and non-biodegradable pollutants, posing risks to both the environment and human health.

The management of plastic waste in landfills is crucial. While microbial degradation shows promise in breaking down plastics, improved waste management practices and policies are urgently needed to mitigate the harmful effects. The best approach is to limit plastic use through substitution or reuse, with separate collection and recycling as the second-best option. Controlled landfills, where the exchange with the surrounding environment is prevented, are also essential to minimise the release of harmful substances.

Plastic Waste in Bodies of Water

Plastic waste in bodies of water, including rivers, streams, lakes, and oceans, is a global issue. Most plastic enters the ocean from middle-income countries, particularly in Asia, due to inefficient waste management infrastructure. Once in the ocean, plastic waste is challenging, if not impossible, to retrieve, especially when it breaks down into microplastics.

The primary sources of plastic entering bodies of water are storm drains, stormwater runoff, and marinas. Plastic waste in these water bodies can be contained using debris booms and intercepted with mechanical systems like litter interceptors. However, the most effective solution is to prevent plastic waste from reaching these water sources in the first place, through improved waste management, recycling, better product design, and reduced manufacturing of single-use plastics.

Plastic recycling rates

Plastic was invented in 1907, and since 1950, about 9 billion tons of plastic have been produced. The world now produces over 450 million tons of plastic annually, with global production doubling in the last two decades.

The recycling rates for plastic are low compared to other materials. The US, for example, recycled only 3 million tons of plastic in 2018, an 8.7% recycling rate. This is in contrast to paper, which had a 66% recycling rate in 2020. The recycling rate for plastic has always been low, never reaching 10%. In 2021, the US recycling rate fell to 5-6%.

The EPA's data on plastic recycling in the US comes from the American Chemistry Council, the National Association for PET Container Resources, and the Association of Plastic Recyclers. While the overall rate is low, the recycling rate for some specific types of plastic containers is more significant. The recycling rate of PET bottles and jars was 29.1% in 2018, and the rate for HDPE natural bottles was 29.3%.

Richer countries have been polluting the oceans for longer, and higher-income countries in Europe and North America have contributed more plastic to the oceans historically. However, most ocean plastic today comes from middle-income countries, particularly in Asia, where waste management infrastructure is poorer.

Mismanaged waste, which is waste that is not recycled, incinerated, or stored in sealed landfills, is at risk of polluting the environment. It is estimated that 1-2 million tons of plastic enter the oceans annually, and about 85% of plastic ends up in landfills.

Plastic waste in oceans

Plastic was first invented in 1907 by Leo Baekeland, who named his product "Bakelite". However, the mass production of plastic only began in the 1950s. Since then, about 9 billion tons of plastic have been produced, with the world currently producing over 450 million tons annually. This rapid increase in plastic production has led to a significant amount of plastic waste, with the world generating around 350 million tons of plastic waste each year. Unfortunately, a large portion of this plastic waste is not properly managed, leading to environmental pollution.

The plastic waste in oceans comes from a variety of sources, including discarded plastic bags, bottles, six-pack rings, cigarette butts, and fishing nets. These larger pieces of plastic, known as macroplastics, can be ingested by marine species, leading them to feel full without receiving adequate nutrition. Additionally, plastic waste can entangle marine animals, restricting their movement and causing starvation, laceration, and infection.

Another significant contributor to plastic waste in oceans is microplastics. Microplastics are tiny particles formed from the breakdown of larger plastic materials. They can be found in products like vehicle tires, textiles, liquid soaps, and shampoos. Once microplastics enter the ocean, they are nearly impossible to filter out and become a permanent part of the marine ecosystem. These microplastics are consumed by marine life, and their potential impact on human health is still unknown.

Addressing the issue of plastic waste in oceans requires a multi-faceted approach. It involves reducing plastic production and consumption, improving recycling practices, and implementing better waste management systems, especially in middle-income countries. Additionally, individuals can play a role by reducing their use of single-use plastics, properly disposing of plastic waste, and participating in cleanup efforts to remove plastic litter from oceans and other water bodies.

Plastic's environmental impact

Plastic was first invented in 1907 by Leo Baekeland, who named his product 'Bakelite'. However, the rapid growth of the global plastics industry didn't occur until the 1950s. Since then, the annual production of plastics has increased nearly 230-fold, with the world now producing over 450 million tonnes of plastic each year.

The environmental impact of plastics is significant and far-reaching. Plastic pollution has become ubiquitous in natural and built environments, with research showing that once plastic enters the environment, it can take between 100 to 1,000 years to decompose, depending on the environmental conditions. This pollution has a detrimental effect on marine wildlife, with more than 1,500 species in marine and terrestrial environments known to ingest plastics. It also damages soil, poisons groundwater, and contributes to the climate crisis. The production of plastic is energy-intensive, and in 2019, plastics generated 1.8 billion metric tonnes of greenhouse gas emissions, accounting for 3.4% of the global total.

The packaging sector is the largest generator of single-use plastic waste in the world, with approximately 36% of all plastics produced being used in packaging. Single-use plastics are common in many products today, and the fashion industry is another major user of plastic, with about 60% of the material made into clothing containing plastic, including polyester, acrylic, and nylon. Every time these clothes are washed, they shed tiny plastic fibres called microfibres, which are a form of microplastic. Laundry alone causes around 500,000 tonnes of plastic microfibres to be released into the ocean every year.

The impact of plastic pollution is not limited to the marine environment. Plastic pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change and directly affecting millions of people's livelihoods, food production capabilities, and social well-being. Furthermore, the mismanagement of plastic waste, particularly in low-to-middle-income countries, exacerbates the problem. This mismanagement includes the lack of recycling, incineration, or proper disposal of plastic waste, leading to its accumulation in the environment and vulnerability to leaking into oceans, rivers, and lakes.

To address the plastic pollution crisis, systemic reform is necessary. This includes encouraging innovation, providing incentives for businesses to reduce unnecessary plastics, and improving waste management infrastructure. Individual choices also play a role, such as avoiding single-use plastic products, reusing and repurposing plastic items, and properly recycling or disposing of plastic waste.
