What You'll Learn
Plastic waste in oceans
The world produces around 350 to 400 million tons of plastic waste each year. While it is difficult to determine the exact amount of plastic that ends up in the oceans, it is estimated that at least 1 million tons of plastic enter the oceans annually, with some estimates ranging from 1.1 to 1.7 million tons. This amounts to 2,000 truckloads of plastic being dumped into the ocean, rivers, and lakes every day.
The fate of plastics in the ocean has puzzled researchers, as the amount of plastic floating on the surface is significantly less than the estimated amount entering the ocean. This has been termed the 'missing plastic problem'. One possible explanation is that our estimates are inaccurate, as plastic waste can take various forms, including microplastics and microfibers, which are difficult to track.
Addressing the issue of plastic waste in oceans requires a multifaceted approach. Implementing waste collection and recycling infrastructure globally can help reduce plastic pollution and improve public health. It is also essential to reduce the volume of plastic produced and used, holding plastic producers accountable for the harmful waste they generate. Strategies such as passing policies to reduce single-use plastic and promoting reusable alternatives can also help mitigate the problem.

Plastic waste in landfills
Plastic waste is a critical global issue. The world produces over 450 million tons of plastic annually, with rich countries producing the most waste per person. However, the amount of plastic waste that ends up in the ocean is more closely linked to how waste is managed. When plastic waste is not recycled, incinerated, or stored in sealed landfills, it becomes vulnerable to polluting the environment.
In the United States, plastic waste has increased fivefold from 1980 to 2018, reaching 35.7 million tons. Despite the availability of recycling bins, the recycling rate has decreased since 2018, with only 5-6% of plastic recycled in 2021. The rest ends up in landfills or is incinerated. This is due to a "decades-long misinformation campaign to perpetuate the myth that plastic is recyclable," according to Judith Enck, the president of Beyond Plastics.
The issue is not limited to the United States. A global study found that only 9% of all plastic ever made has likely been recycled, with the vast majority (79%) accumulating in landfills or sloughing off in the natural environment as litter. By 2050, it is predicted that there will be 12 billion metric tons of plastic in landfills, a staggering amount that highlights the urgency of the situation.
To address plastic pollution, waste management strategies must be improved, especially in low-to-middle-income countries where waste management infrastructure is often lacking. Reducing single-use plastic items and switching to systems of reuse and refill are also crucial steps in tackling this global issue.

Plastic waste incineration
Plastic waste is a pressing global issue, with over 450 million tons produced annually, and up to 50% used for single-use purposes. While incineration may seem like a viable solution, it comes with significant drawbacks and risks.
Incineration, or burning plastic waste, is a method of waste treatment that generates electricity. However, it is not a sustainable solution due to the release of harmful pollutants and the encouragement of continued plastic production. The burning of plastics contributes to air pollution, releasing toxins such as microplastics, bisphenols, and phthalates, dioxins, heavy metals, and greenhouse gases. These emissions pose risks to human health, affecting neurodevelopment, endocrine, and reproductive functions, and impacting communities located near incinerators.
In addition, the constant feeding required by incinerators competes with recycling and composting initiatives. The high cost of building and operating incinerators, coupled with the need for long-term contracts, often results in local councils prioritizing incineration over waste reduction and recycling efforts. This further perpetuates the plastic crisis.
Furthermore, the electricity generated from plastic incineration is highly polluting, even dirtier than coal. With global plastic production projected to triple by 2060, the urgency to address the plastic crisis cannot be overstated.
To effectively tackle the plastic waste problem, a comprehensive approach is necessary. This includes reducing plastic production, promoting circular economy solutions such as reuse and refill, improving waste management infrastructure, and investing in renewable energy sources. While incineration may seem like a convenient solution, it ultimately exacerbates the environmental and health impacts of plastic pollution.
In summary, plastic waste incineration is not a sustainable solution to the global plastic crisis. It contributes to air pollution, poses health risks, and distracts from more effective strategies focused on reduction, reuse, and recycling. Addressing the plastic waste problem requires systemic changes and a commitment to transitioning to renewable energy sources.

Plastic pollution in ecosystems
Plastic pollution is a pressing issue for ecosystems around the world. The proliferation of plastic products in recent decades has been extraordinary, with humans producing over 350-400 million tons of plastic annually. While plastic is cheap and versatile, it has become an environmental issue due to its persistence and accumulation in nature.
The mismanagement of plastic waste is a significant concern. Nearly a quarter of all plastic waste is mismanaged or littered, amounting to around 82 million tonnes globally. This waste is not securely landfilled, recycled, or incinerated, leading to 19 million tonnes of plastic leaking into terrestrial and aquatic environments.
One of the most affected ecosystems is the ocean. While the exact amount of plastic entering the oceans is uncertain, it is estimated that more than 1 million tonnes, and possibly up to 8 million tonnes, of plastic end up in the oceans annually. This plastic pollution has severe consequences for marine life and ecosystems. For instance, plastic debris can entangle marine animals, leading to injury or death, and it can also be ingested, causing health issues and even death.
In addition to the direct impacts on marine life, plastic pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change. This has indirect effects on millions of people's livelihoods, food production capabilities, and social well-being. For example, plastic pollution can damage coral reefs, which are vital habitats for numerous marine species and provide coastal protection from storms and erosion.
To address plastic pollution in ecosystems, it is crucial to reduce plastic consumption and improve waste management practices. This includes increasing recycling rates, properly disposing of plastic waste, and advocating for policies that promote sustainable plastic use and hold plastic producers accountable for their waste. By taking collective action, we can mitigate the harmful impacts of plastic pollution on ecosystems and work towards a more sustainable future.

Plastic pollution in food and drink
Plastic is a synthetic, organic polymer made from fossil fuels, such as gas and petroleum. Over 450 million metric tons of plastic are produced annually, according to the United Nations Environment Programme. The production of plastic has sharply increased over the last 70 years, with global production doubling in the last two decades. The world produces around 350 million tons of plastic waste each year, with an estimated 10 million tons of plastic dumped into our oceans annually.
Plastic pollution is a pervasive and escalating global environmental problem, named among the most serious issues globally, after climate change. It affects nearly every ecosystem, threatening wildlife, public health, and economic activities that depend on healthy marine ecosystems. Plastic waste pollutes and harms the environment, becoming a widespread driver of biodiversity loss and ecosystem degradation. It threatens human health, affects food and water safety, burdens economic activities, and contributes to climate change.
The food and beverage sector is a major user of single-use plastic packaging, and while consumer concerns have driven some changes in food packaging trends, the transition to sustainable packaging in this sector is slow and inconsistent. Most corporate sustainability reports fail to address plastic pollution, focusing instead on collection and recycling. However, some larger companies are moving towards using cans and glass packaging, and some innovative solutions such as edible films and coatings with additional functions like antioxidant and antimicrobial properties are being developed.
Microplastics have been found in human food and drinks, including bottled water, tap water, beer, salt, and various processed foods. Heating food in plastic containers, storing food in sunlight or warm environments, and the consumption of highly processed foods can increase the presence of microplastics. Beverages are also affected by plastic pollution, with carbonated drinks facing the issue of CO2 leaking out of the headspace of sealed drinks over time, causing them to go flat. Initiatives from major brands include establishing sustainability policies that promise innovation in the direction of less plastic use and greater resources to support reusability.
