Plastic Pollution: Takeout's Dark Side Revealed

Takeout food is a major contributor to the world's plastic waste problem. While the exact amount of plastic waste from takeout is unknown, a study by the University of Cadiz, Spain, found that nearly half of the 12 million pieces of litter collected from oceans, rivers, shorelines, the sea floor, and open waters were related to takeout food and drinks. This includes single-use bags, plastic bottles, food containers, and food wrappers, as well as plastic caps, lids, and disposable cutlery. Restaurants account for 78% of all disposable packaging, with an estimated 282 billion napkins used annually in the United States alone. While some restaurants are trying to reduce their plastic footprint by adopting reusable containers and buy-back schemes, the problem is far from solved.

Plastic takeout containers

Plastic pollution is a pressing issue, with plastic waste accumulating at a rapid rate. While plastic has many valuable applications, its pollution is an unnecessary and unsustainable waste of resources. The production of plastic is energy-intensive, derived from fossil fuels, and has severe environmental consequences.

Take-out containers are a significant contributor to plastic waste. In 2017, plastic take-out containers were among the top 10 kinds of trash collected during the International Coastal Cleanup. The convenience and popularity of take-out food result in a high consumption of these containers, which are often single-use and quickly discarded. While some end up in landfills, many find their way into oceans, becoming marine debris.

The impact of plastic take-out containers on the environment is twofold. Firstly, they contribute to the vast amount of plastic waste that enters our oceans each year. Marine animals ingest or become entangled in plastic debris, causing an estimated 100,000 deaths annually. Secondly, the production and incineration of plastic waste contribute to the climate crisis. Plastic production is energy-intensive, accounting for around 8% of global annual oil and gas use. Incineration, a common method of plastic waste disposal, releases carbon dioxide and other greenhouse gases into the atmosphere.

To address the issue of plastic take-out containers, individuals can make conscious choices to reduce their plastic consumption. Reusable containers are a more sustainable alternative for storing leftovers. Supporting restaurants that use compostable or recyclable containers is also a step in the right direction. Policy instruments, such as taxes on single-use plastics and incentives for reusable options, are necessary to encourage businesses and consumers to reduce plastic consumption and promote circularity.

Education is a powerful tool in the fight against plastic pollution. Spreading awareness about the consequences of plastic waste and promoting sustainable alternatives can foster a collective effort for a greener planet.

Plastic waste in oceans

Plastic waste is a significant contributor to ocean pollution, with an estimated 8 million metric tons of plastic entering the ocean annually. This plastic waste comes from various sources, including single-use items such as take-out containers, water bottles, and plastic bags. These items are often designed to be thrown away after a single use, and if not properly disposed of or managed, they can find their way into the ocean.

Plastic waste in the ocean has severe consequences for marine ecosystems, wildlife, and even human health. It affects the health of marine species, food safety, human health, and coastal tourism, contributing to climate change. Marine life can become entangled in plastic debris, leading to injury or death. Additionally, animals may mistake plastic debris for food, causing ingestion and potentially fatal blockages.

The impact of plastic waste in the ocean is not limited to the marine environment. Coastal communities bear the brunt of the consequences, facing high cleanup costs and negative effects on the fishing and tourism industries. The economic costs associated with plastic pollution in the ocean are substantial, with estimates ranging from $6 billion to $19 billion USD annually.

Addressing the issue of plastic waste in the ocean requires a multifaceted approach. While individual actions, such as reducing plastic use, reusing and recycling, and proper waste disposal, are crucial, systemic changes are also necessary. This includes improving waste management systems, particularly in low- to middle-income countries, where plastic usage is increasing and inadequate waste management systems struggle to keep up with the rising consumption. Additionally, holding plastic producers accountable for the harmful waste they generate is essential.

While the exact amount of plastic waste in the ocean is challenging to determine, it is clear that the problem is significant and requires immediate action. By working together and implementing sustainable practices, we can reduce the amount of plastic entering our oceans and mitigate the harmful impacts on our planet's health and the well-being of future generations.

Plastic recycling

The recycling process typically involves melting and reforming plastic into new items, which can cause polymer degradation. Sorting plastic waste by colour and polymer type is a complicated and expensive step, and errors can result in material with inconsistent properties. Although filtration can reduce microplastic release, even the most advanced filtration systems cannot completely prevent the release of microplastics into wastewater. Feedstock recycling, which converts waste plastic into its starting chemicals, carries higher energy and capital costs.

The recycling rates for plastic lag behind those of other materials like aluminium, glass, and paper. From the start of plastic production until 2015, the world generated approximately 6.3 billion tonnes of plastic waste, with only 9% recycled and only 1% recycled more than once. The remaining waste was incinerated, sent to landfills, or contributed to environmental pollution. Plastic waste that is not properly managed, through recycling, incineration, or sealed landfills, becomes an environmental pollutant, with an estimated 1 to 2 million tonnes of plastic entering our oceans each year.

To address the issue of plastic waste, it is crucial to improve waste management practices, especially in poorer countries, from which most ocean plastics originate. Efforts to reduce, reuse, and recycle plastics are essential to minimise the environmental impact. While plastic recycling has its challenges, advancements in technology and increased investment in research are expanding the scope of recyclable plastic materials. Additionally, initiatives by supermarkets and retailers to collect a wider range of plastic bags and wrappings, known as soft plastics, have enhanced recycling efforts.

Plastic waste in landfills

Plastic waste is a critical global issue, with a vast amount ending up in landfills. The problem is growing, and the environmental impact is severe.

Landfills are a common method for dealing with plastic waste, but they are not a sustainable solution. The plastic waste in landfills is subjected to severe environmental conditions, including varying pH levels, high salinity, fluctuating temperatures, and microbial degradation. These factors contribute to the breakdown of plastics into microplastics (MPs), which are then released into the surrounding environment through air and water. Even when landfills are sealed, they can still be a source of MPs, as plastic debris continues to break down over time. The abundance of MPs in landfill refuse is estimated to be 20,000–91,000 items per kg, which is significantly higher than the concentrations found in sediments, sewage sludge, and agricultural soil.

The amount of plastic waste in landfills is staggering. In the United States alone, it is estimated that 40 million tons of plastic waste were generated in 2021, with 85% ending up in landfills. This is a significant increase from previous years, with plastic waste in the US increasing fivefold from 1980 to 2018. The recycling rate for plastic waste in the US has been declining, with only 5-6% recycled in 2021, down from 8.7% in 2018. The situation is similar in other parts of the world, with global plastic production doubling in the last two decades. It is estimated that 91% of plastic is not recycled, with 79% accumulating in landfills or littering the natural environment.

The impact of plastic waste in landfills extends beyond the environmental consequences of microplastics. Plastic waste also represents a significant loss of energy and economic value. Scientists have calculated that the energy value of landfilled plastic waste in the US in 2019 was enough to supply a considerable portion of the power used by the transportation or industrial sectors. The market value of this wasted plastic is estimated to be in the billions of dollars. Additionally, the management of plastic waste is a challenge, especially in low-to-middle-income countries, where a significant portion of plastic waste enters the oceans, affecting wildlife and ecosystems.

To address the issue of plastic waste in landfills, a comprehensive global approach is necessary. This includes rethinking plastic chemistry, product design, recycling strategies, and consumer use. Developing new recycling techniques and reducing the use of single-use plastics are crucial steps towards a more sustainable future.

Plastic waste incineration

Plastic waste is a critical global issue, with plastic production increasing nearly 230-fold between 1950 and 2019. While incineration may seem like a viable solution to eliminate plastic waste, it comes with significant drawbacks and risks. Incineration, or burning plastic waste, is a method of waste treatment that generates electricity. However, it is crucial to understand that incineration does not address the root cause of plastic pollution and has adverse effects on human health and the environment.

Burning plastic waste releases toxic pollutants, including microplastics, bisphenols, and phthalates, dioxins, heavy metals, and other harmful particles and gases. These toxins can contaminate the air, disrupt neurodevelopment, and impair endocrine and reproductive functions. Additionally, the toxins released during incineration can accumulate in nearby areas, rendering items like chicken eggs unsuitable for consumption.

The drawbacks of incineration go beyond the immediate health and environmental risks. Incinerators are expensive to construct and operate, requiring substantial investments from communities. They also compete with recycling and composting facilities, as they need a constant supply of waste to remain operational. This competition can hinder efforts to reduce plastic consumption and promote recycling, as communities may prioritize feeding the incinerators to justify their investment.

Furthermore, the electricity generated from plastic incineration is highly polluting. It is even dirtier than coal, contributing to the climate crisis. With global plastic production projected to triple by 2060, the urgency to address plastic waste is undeniable. However, incineration is not a sustainable solution, as it encourages more plastic production to replace what is burned, leading to a continuous rise in emissions.

To effectively tackle plastic waste, it is essential to focus on reducing plastic production and promoting a circular economy through reusing, repurposing, and recycling. While incineration may seem like a convenient solution, it is a short-sighted approach that exacerbates environmental pollution and poses risks to human health. Addressing the plastic crisis requires systemic changes and a commitment to sustainable alternatives.
