The World's Plastic Problem: Yearly Waste Crisis

Plastic waste is one of the most pressing issues facing the planet today, with its impact felt from the tallest mountains to the deepest ocean trenches. Humans currently produce over 350 million metric tons of plastic waste per year, with some reports indicating that up to 50% of this is for single-use purposes. The plastic waste problem has been exacerbated in recent decades as the consumption of this versatile material has continued to rise. While the lifespan of plastic products averages around 10 years, they can take up to 500 years to decompose, depending on their composition and disposal method. The majority of plastic waste is either landfilled or incinerated, releasing harmful pollutants into the atmosphere. Mismanaged plastic waste, which is not recycled, incinerated, or stored in sealed landfills, often ends up in illegal dumpsites or burned in open pits, and can leak into the environment, including rivers and oceans. It is estimated that between 1 and 2 million tons of plastic enter our oceans each year, threatening marine life and ecosystems.

Global plastic waste generation is projected to triple by 2060

Plastic waste is one of the most pressing issues facing the planet today. The world currently produces around 350 million metric tons of plastic waste each year, with global plastic production doubling since the turn of the century. The average lifespan of plastic products is around 10 years, but they can take up to 500 years to decompose, depending on their composition and disposal method. This means that plastic waste is accumulating at an alarming rate.

The problem of plastic waste has been exacerbated by the sharp rise in plastic consumption in recent decades. Without significant changes to current policies, the amount of plastic waste generated globally is projected to triple by 2060, reaching a staggering one billion metric tons. This increase in plastic waste will have devastating consequences for the environment, with a significant impact on human health, ecosystems, and wildlife, particularly marine species.

The 2022 OECD report, Global Plastics Outlook: Policy Scenarios to 2060, highlights the urgent need for radical action to address the issue of plastic pollution. According to the report, almost two-thirds of plastic waste in 2060 will be from short-lived items such as packaging, low-cost products, and textiles. The report also emphasizes the critical role of public authorities in promoting reuse systems for takeaway packaging.

While recycling rates are expected to improve, rising from 9% in 2019 to a projected 17% in 2060, this will still be outpaced by the increase in plastic waste generation. Landfilling and incineration are expected to account for 50% and 18% of plastic waste disposal, respectively. Population growth and economic development, particularly in emerging economies, are key drivers of the projected surge in plastic waste.

To address this pressing issue, ambitious measures and policies must be implemented. This includes increased taxes on plastic use and a significant improvement in global recycling systems. By taking decisive action, the amount of plastic waste generated can be reduced, mitigating the environmental impact and preserving the planet for future generations.

Plastic waste in the oceans

Plastic waste is one of the biggest issues facing the planet today, with its impact felt everywhere from the tallest mountains to the deepest ocean trenches. The world produces around 350 million tonnes of plastic waste each year, and it is estimated that between 1 and 2 million tonnes of plastic enter the oceans annually. This means that 0.5% of plastic waste ends up in the ocean, although this still equates to over 1 million metric tons of pollution.

One of the primary sources of plastic waste in the oceans is improper waste management. In many countries, particularly low- to middle-income countries, waste management infrastructure is lacking, leading to mismanagement of plastic waste. This includes practices such as illegal dumping, open burning, and littering, which increase the risk of plastic leaking into rivers and oceans. It is estimated that half of the world's plastic waste goes into landfills, while another fifth is mismanaged, contributing to environmental pollution.

Another factor contributing to plastic waste in the oceans is the increasing consumption of plastic products. Plastic is a versatile and affordable material used in various applications, including food packaging, construction, home appliances, and medical instruments. However, many plastic products are designed as single-use items, leading to a rapid increase in plastic waste. The consumption of plastic is projected to continue rising, with the fossil fuel industry planning to increase plastic production by 40% over the next decade.

The impact of plastic waste in the oceans is devastating for marine life and ecosystems. Marine animals, such as seabirds, sea turtles, seals, and whales, ingest plastic or become entangled in it, leading to injuries and mortality. Plastic debris can also absorb harmful pollutants, such as pesticides and dyes, and release them into the ocean, further exacerbating the problem. Additionally, plastic waste can accumulate in convergences that make up about 40% of the world's ocean surfaces, and it is predicted that by 2050, plastic will outweigh all the fish in the sea.

Plastic waste in rivers and lakes

The world produces around 350 million tonnes of plastic waste each year. Of this, it is estimated that between 1 and 2 million tonnes of plastic enter the oceans annually. This plastic waste enters the oceans through various pathways, and one of the major pathways is rivers.

Rivers are a significant conduit for plastic waste to reach the oceans, and it is estimated that between 1.15 and 2.41 million tonnes of plastic waste enter the oceans from rivers every year. This plastic waste in rivers comes from a variety of sources, including mismanaged waste, population density, and hydrological factors. The probability of plastic waste being emitted into the ocean from rivers is influenced by factors such as terrain, winds, precipitation, and river patterns.

A study found that 88-95% of all river-borne plastic comes from just 10 rivers, with eight of these rivers located in Asia: the Yangtze, Indus, Yellow, Hai He, Ganges, Pearl, Amur, and Mekong. These rivers are characterized by a high population in the surrounding region and less-than-ideal waste management processes. The Yangtze, Asia's longest river, is considered one of the world's most ecologically important rivers, and its river basin is home to almost 500 million people.

The accumulation of plastic waste in rivers and lakes has significant impacts on marine life and ecosystems. It is estimated that more than 100 million tons of plastic waste had accumulated in rivers and lakes between 1970 and 2019. This plastic waste in freshwater systems can have adverse consequences for both the environment and human health.

To address the issue of plastic waste in rivers and lakes, effective mitigation strategies are necessary. This includes improving waste management practices, raising public awareness, and implementing policies to reduce plastic consumption and improve recycling systems.

Plastic waste in the EU

Plastic waste is a pressing issue in the EU, with far-reaching environmental and health consequences. The average annual plastic consumption in Western Europe is around 150kg per person, more than twice the global average of 60kg. In 2021, each person living in the EU generated an average of 36.1kg of plastic packaging waste, with the total plastic waste produced in the EU that year reaching 16.13 million tonnes. While EU countries have been recycling more plastic waste, they also generate more of it.

The EU's main approach to dealing with plastic waste is energy recovery, which involves turning plastic waste into usable heat, electricity, or fuel through incineration or other processes. However, this method has its drawbacks, as incineration contributes to air emissions and climate change. Recycling is the second most common way the EU deals with plastic waste. In 2021, about 6.56 million tonnes of plastic waste were recycled in the EU, with the Republic of Ireland leading the way in plastic recycling within the bloc, recycling 20.70kg of plastic waste per capita. However, the diversity of raw materials used in plastics complicates the recycling process, making it costly and affecting the quality of the end product. As a result, the demand for recycled plastics is growing rapidly, with the EU adopting new rules to increase the recycled content in plastic bottles to 25% by 2025 and 30% by 2030.

The EU is taking action to tackle plastic pollution and marine litter, with specific rules, targets, and guidelines for single-use plastics, plastic packaging, microplastics, and biodegradable plastics. Despite these efforts, plastic waste continues to find its way into the oceans, with an estimated 10 million tonnes of plastic dumped into the oceans annually. Microplastics, which can contaminate soil, air, and water, pose a significant threat to marine life and human health through the food chain. The EU's plastics strategy, as part of the circular economy action plan, aims to address these challenges and find more sustainable ways to manage plastic waste.

Plastic waste in the US

Plastic waste is a significant environmental issue, and the United States is a major contributor to the growing global problem. In 2019, the US generated an estimated 73 million metric tons of plastic waste, which equates to more than 220 kilograms per person. This was approximately five times the global average per capita.

The demand for plastics in the US does not appear to be slowing, and the country's waste generation is projected to exceed 140 million metric tons by 2060. This issue has been exacerbated by the stagnation of the domestic plastic recycling rate, which remains relatively small. While certain types of plastic containers, such as PET bottles and jars, and HDPE natural bottles, have higher recycling rates (29.1% and 29.3% respectively in 2018), the overall US recycling system is struggling.

The US exports large volumes of plastic waste to other countries, particularly Canada and Mexico, its North American neighbours. However, since China restricted foreign waste imports, US plastic waste exports have decreased, further straining the domestic recycling system. Plastic waste has numerous negative consequences for the environment and health, with Americans most concerned about its impact on marine life. It is estimated that more than 10 million tons of plastic are dumped into the oceans annually, and with 57% of plastic waste coming from plastic bottles, this is a significant concern.

Plastics are found in a wide range of products, from nondurable items like disposable diapers, trash bags, cups, utensils, and medical devices to durable goods such as appliances, furniture, and casings for batteries. The containers and packaging category, which includes bags, sacks, wraps, bottles, and jars, had the highest plastic tonnage in 2018, at over 14.5 million tons. With the US consuming far more plastic than it can recycle, the issue of plastic waste is a pressing one that requires urgent attention.
