Reusing plastic containers from restaurants is a complicated topic. While it may seem like a simple way to save money and reduce waste, there are safety concerns to consider. The type of plastic a container is made of determines its suitability for reuse. Some plastics, such as #1 (polyethylene terephthalate), #3, and #6 (styrofoam), should not be reused and should only be recycled. Other plastics, like #2, #4, and #5, are generally considered safe for storing food and can be reused until they show signs of wear and tear. It is important to avoid using any containers with scratches or discolouration as this may indicate the presence of harmful chemicals or microplastics. Glass containers, on the other hand, can be safely reused indefinitely as long as they are cleaned and free from cracks or damage.

What You'll Learn
Plastic containers should not be used to reheat food
Plastic containers are not suitable for reheating food. While they are convenient for storing food, they are not designed for repeated use and can pose health risks when used for reheating.
Firstly, it is important to identify the type of plastic a container is made of. Different types of plastics are created for different uses, and some types, such as #1 (polyethylene terephthalate or PET), #3, and #6 (styrofoam), should not be reused at all. To determine the type of plastic, one can refer to the recycling symbol on the bottom of the container, which corresponds to the specific type of plastic.
When plastic containers are reheated, they can leach out plasticizers and other harmful chemicals over time. This is because plastics are made up of strong chemical bonds that break down into microplastics and nanoplastics, which can end up in your food. Additionally, heat can damage the packaging, causing it to degrade and increasing the likelihood of chemical leaching. Even if a container is labelled as "microwave-safe", it does not guarantee that it is safe for your health.
Furthermore, plastic containers should not be washed in the dishwasher as the high temperatures and abrasion from washing can cause further breakdown of the plastic. If you intend to reuse plastic containers, it is recommended to hand-wash them with a sanitizing solution and avoid using them for reheating food.
Instead of reusing plastic containers for reheating, it is safer to use alternative materials such as glass or ceramic. Glass containers are durable, non-reactive, easy to clean, and suitable for reheating in the microwave. Ceramic containers are also strong, reusable, and microwave-safe. These alternatives provide a safer option for reheating food without the risk of chemical leaching associated with plastic containers.

Glass containers are safe to reuse indefinitely
Reusing plastic containers from restaurants requires careful consideration and investigation. Firstly, it's important to determine what type of plastic the container is made of, as some plastics are safer for reuse than others. For instance, plastics #1, #3, and #6 are not recommended for reuse and should be recycled instead. On the other hand, plastics #2, #4, and #5 are considered safer for reuse and food storage. However, it is advised to avoid using any plastic containers for reheating food, especially in the microwave, as they may leak harmful chemicals. Additionally, plastic containers should be discarded once they show signs of wear and tear, such as scratches, discolouration, or cloudiness, to prevent the leaching of chemicals or microplastics into food.
Now, let's focus on glass containers, which offer a safer and more sustainable alternative for reuse.
Glass containers, including jars and bottles, can be safely reused indefinitely. Glass is chemically inert, meaning it does not react with or leach into its contents, ensuring your food remains safe and uncontaminated. Unlike plastic, glass does not contain harmful chemicals like BPA and phthalates, which can pose potential health risks when leached into food, especially when heated. Glass is also non-porous, so it doesn't absorb odours, flavours, or stains, making it ideal for storing a variety of foods without worrying about lingering smells or discolouration.
Glass containers are incredibly versatile and durable. They can go from the freezer to the oven or microwave without any concerns about releasing harmful chemicals. Many glass containers are also dishwasher-safe, making cleaning convenient. Additionally, glass containers often have timeless and elegant designs that complement various kitchen aesthetics.
By choosing to reuse glass containers, you not only reduce your environmental impact by decreasing the demand for single-use plastics but also contribute to a more sustainable and eco-friendly lifestyle. Glass is 100% recyclable, and its durability ensures it can be reused for years without losing quality, making it a cost-effective and environmentally conscious choice for kitchen storage.
In summary, while it is possible to reuse plastic containers from restaurants with caution and knowledge of the plastic type, glass containers are the safer and more sustainable option for indefinite reuse, offering peace of mind and a reduced environmental footprint.

Styrofoam containers should be avoided
Reusing plastic containers from restaurants is complicated and requires investigation and consideration. It is important to determine what type of plastic a container is made of, as some types of plastic are safer for reuse than others. Plastic containers should not be used to reheat food or washed in the dishwasher, and they should be recycled once they start to show signs of wear and tear.
However, Styrofoam containers, which are made of polystyrene, should be avoided altogether. Polystyrene is a non-biodegradable, synthetic, hard plastic commonly used to make household items and food packaging. It is terrible for the environment and human health due to its toxicity. Study after study shows that chemicals from polystyrene, especially styrene, leach into foods and beverages, particularly when exposed to high temperatures and foods with high fat content. Styrene exposure increases the risk of leukemia and lymphoma and is a neurotoxin. It has also been associated with respiratory problems and "styrene sickness," which includes headaches, fatigue, and feelings of drunkenness. In addition, polystyrene products cannot be broken down or consumed by living organisms, so they often end up polluting our land and waterways, causing harm to fish and other animals.
Due to the known health and environmental hazards of polystyrene, it is best to avoid using Styrofoam containers. Instead, opt for reusable containers made from safer materials, such as glass or certain types of plastic, to reduce your impact on the environment and potential exposure to harmful chemicals.
To identify Styrofoam containers, look for the recycling symbol on the bottom, which will indicate the type of plastic. Styrofoam containers are typically made of expanded polystyrene (EPS) or extruded polystyrene (XPS). These containers are often used for takeout food, drinks, and single-use utensils and dinnerware in restaurants.
In summary, while it may be tempting to reuse plastic containers from restaurants, it is important to exercise caution. Styrofoam containers, in particular, should be avoided due to their negative impact on human health and the environment. By choosing reusable and recyclable alternatives, you can make a more sustainable and safe choice.

Plastic containers should be hand-washed with a sanitiser solution
Reusing plastic containers from restaurants is a complicated matter. It is important to determine what type of plastic a container is made of before reusing it. The safest plastics to reuse are plastics #2, #4, and #5. Plastic containers should not be used to reheat food or washed in the dishwasher. If you intend to reuse plastic containers, it is best to hand-wash them with a sanitiser solution.
To create a sanitiser solution for hand-washing plastic containers, Shawn Matijevich, the lead chef of online culinary arts and food operations at the Institute of Culinary Education, recommends using a solution with 200ppm chlorine bleach. He suggests putting the solution in a spray bottle and misting the containers after washing, allowing them to air-dry.
It is important to note that plastic containers should only be reused for a short period of time and for storing cold or room-temperature items. They should not be used for acidic or saucy foods, as these can encourage leaching. Additionally, plastic containers should be discarded once they start to show signs of wear, such as scratching, discolouration, or cloudiness, to prevent the risk of bacterial build-up or leaching plastic.
While reusing plastic containers may not be as straightforward as one would hope due to the uncertainty about what goes into plastic products, taking the necessary precautions can help ensure safe reuse. However, it is always important to check the manufacturer's recommendations and guidelines for reusing specific types of plastic containers.

Plastic containers should be recycled when scratched or discoloured
Reusing plastic containers from restaurants is not as straightforward as one would hope. While it is technically possible to reuse them, there are several factors to consider, and it is generally recommended to recycle them instead.
Firstly, it is important to identify the type of plastic the container is made of. Most food containers, including takeout containers, are made of low-density polyethylene or polypropylene. These plastics are labelled with a number surrounded by a triangle, known as the Resin Identification Code, which denotes the base plastic used. Polyethylene is labelled as "4", and polypropylene as "5". It is recommended to refer to guides such as the Tufts University Plastics by the Numbers to determine if a specific type of plastic can be reused.
Once the type of plastic is identified, it is crucial to follow the recommended guidelines for that particular plastic. Some plastics, such as #1 (polyethylene terephthalate or PET), #3, and #6 (styrofoam), should not be reused and should only be recycled. Plastic #7 may contain BPA, which can be harmful to health, according to the National Institute of Environmental Health Sciences. The safest plastics to reuse are #2, #4, and #5, which are safe for storing food.
However, even for plastics that are deemed safe for reuse, there are important precautions to take. It is recommended to avoid using plastic containers for hot foods or reheating purposes, as heat can cause the plastic to break down and leach unknown chemicals into the food. Oily and fatty foods should also be avoided, as many chemicals in plastic are fat-soluble and can leach into fatty foods. Additionally, plastic containers should not be washed in the dishwasher, as this can contribute to their degradation.
Signs of wear and tear, such as scratches or discolouration, indicate that it is time to recycle the container. This is because chemicals can more easily leach into food from worn containers. Glass containers, on the other hand, can be safely reused indefinitely as long as they are cleaned between uses and are free from cracks or other damage.
In summary, while it is possible to reuse plastic soup containers from restaurants, it requires careful consideration and adherence to guidelines. To ensure food safety and reduce the risk of chemical exposure, it is generally recommended to recycle plastic containers when they show signs of scratching or discolouration and opt for glass containers for reuse whenever possible.
