Health risks of plastic to-go containers
Plastic to-go containers have become a significant part of modern life, with the Foodservice Packaging Institute estimating that half of all prepared food comes in plastic. However, the use of these containers has raised concerns about their environmental impact and potential health risks. An increasing number of cities are considering laws restricting or banning single-use plastics for food packaging due to their adverse effects.
Plastic to-go containers pose several health risks, primarily due to the presence of toxic chemicals that can contaminate food. These chemicals include bisphenols, phthalates, and PFAS, which have been linked to adverse health effects. Bisphenols, specifically Bisphenol A (BPA), are endocrine disruptors and have been associated with obesity, fertility issues, and an increased risk of miscarriage. Phthalates are also endocrine disruptors and can interfere with hormones, potentially impacting sexual function and fertility and increasing the risk of cancer. PFAS, or per- and polyfluoroalkyl substances, are highly persistent chemicals that can contaminate soil and waterways, further emphasising the environmental impact of plastic waste.
Additionally, plastic containers can leach metals and chemicals into stored food, especially when subjected to elevated temperatures. Research has detected microplastics in carotid artery plaques, suggesting a potential link between plastic consumption and cardiovascular health issues. Studies have also found that humans ingest a significant number of microplastic particles annually, with takeout containers being a major contributor. The specific health consequences of microplastic ingestion are still being studied, but the presence of chemicals like BPA, phthalates, and PFAS in these plastics is concerning.
To minimise health risks, it is recommended to avoid heating food in plastic containers, as high temperatures can increase the leaching of chemicals and microplastics. Instead, transferring food to glass or ceramic dishes before microwaving or storing is advisable. Reusable containers are also preferable to single-use plastics, reducing both environmental impact and potential chemical exposure. While some alternatives, like compostable packaging, exist, they may also contain toxic chemicals or be challenging to properly compost. Overall, reducing the use of plastic to-go containers and opting for safer alternatives can help mitigate potential health risks associated with plastic food packaging.

Environmental impact of plastic to-go containers
Plastic to-go containers have a significant environmental impact. They contribute to global warming, with plastic production emitting the same amount of emissions as 116 average-sized coal-fired power plants in the United States in 2020. Plastic waste ends up in landfills, where it can take centuries to break down, or in natural environments, including the ocean, where it threatens wildlife, alters ecosystems, and poses risks to human health. Less than 6% of plastic in the United States is effectively recycled, and studies have found that nearly half of the plastic litter in the ocean comes from take-out food and drink containers.
The production of plastic to-go containers also has environmental implications. Plastic is derived from fossil fuels, such as natural gas, crude oil, and coal, and the extraction of these resources has long-lasting effects on the environment, including deforestation and fracking. Additionally, plastic manufacturing is energy-intensive and emits greenhouse gases, contributing to global warming.
The containers themselves can also be a source of contamination. While plastic food containers are asserted to be safe, they are not entirely inert and can leach metals and chemicals into the food they store, especially when subjected to high temperatures. Research has identified numerous chemicals in plastic packaging, many of which have been assessed for toxicity, and some of which are known to be highly toxic and neurotoxic.
The environmental impact of plastic to-go containers has led to a growing movement to reduce, ban, or replace them. Some restaurants are partnering with companies that provide reusable containers for takeout, and several cities and countries are considering or implementing laws to restrict or ban single-use plastic for food. Alternatives to plastic to-go containers include reusable containers, compostable packaging, and traditional materials like clay and glass. While there are challenges to adopting these alternatives, such as the convenience and cost associated with plastic, the environmental benefits of reducing plastic waste are significant.

Regulations and alternatives to plastic to-go containers
Plastic to-go containers have been a significant part of modern life, but they have also contributed to environmental and health concerns. While some countries and municipalities have moved to ban single-use plastics, others are encouraging the use of alternatives like glass, stainless steel, cardboard, and plant-based compostables.
Regulations
Towns, states, and countries have been taking initiatives to ban single-use plastics, including plastic checkout bags, straws, food containers, and takeaway serviceware. For instance, California lawmakers aim to reduce single-use plastic packaging and ensure it is recyclable or compostable by 2032. Similarly, the European Union has banned certain single-use plastics when alternatives are available. Washington State has also introduced legislation for better labelling of compostable products and banning deceptive labelling of plastics.
Alternatives
- Glass containers: Glass is chemically inert and will not leach harmful toxins or substances into food, regardless of temperature. It is safe for the microwave and dishwasher, non-porous, and sustainable as it is made from organic materials like sand, soda ash, calcium carbonate, and recycled glass.
- Stainless steel containers: Stainless steel is lightweight, airtight, and leakproof. It does not contaminate food with damaging chemicals and is suitable for all types of food except acidic foods, which can react with the metal.
- Cardboard containers: Cardboard is breathable, moisture-proof, and heat-resistant, making it suitable for the microwave. It is also 100% compostable and recyclable, making it a more environmentally friendly option than plastic.
- Plant-based compostables: Municipalities are encouraging restaurants and coffee shops to switch to plant-based compostables for takeaway meals. However, some researchers caution that compostable tableware and packaging may not be a perfect solution, as they may contain toxic "forever chemicals" like PFAS, which can contaminate soil and waterways.
It is worth noting that while alternatives exist, some individuals and businesses may face challenges in completely eliminating plastic. For example, a restaurant owner from Southern California expressed the difficulty in finding alternatives to plastic gloves, plastic film wrap, and takeout containers for soups, as plastic provides insulation to keep food hot.
