Plastic is a common material used for storing leftovers, but it can be harmful to the environment and our health. Plastic wrap, for example, is hard to recycle and can leach toxins into food. To store leftovers without using plastic, there are several alternatives, such as beeswax wraps, cloth dish covers, glassware, stainless steel containers, and foil. These options are reusable, washable, and eco-friendly, making them ideal for storing leftovers in the refrigerator or freezer. Proper storage of leftovers helps reduce food waste, saves money, and prevents foodborne illnesses.

Glass jars and containers
When storing leftovers in glass containers, it is important to use shallow dishes and smaller containers to cool food quickly before placing it in the refrigerator. It is also recommended to use airtight containers and to label and date the contents before refrigeration. This helps to ensure that leftovers are eaten or discarded within a safe timeframe.

Beeswax wraps
To use beeswax wraps, simply lay one over a bowl, dish, or jar and gently press around the edges. The warmth of your hands will help soften and slightly melt the beeswax, creating a protective seal. You can also use them to wrap fruits, vegetables, cheese, bread, and sandwiches. Beeswax wraps are perfect for covering leftovers and storing them in the refrigerator.

Stainless steel containers
There are several options for stainless steel containers available. IKEA 365+ containers are super affordable and come in a range of materials, including stainless steel with interchangeable plastic lock lids. While these containers are microwave-safe, it's important to note that exposing plastic to high heat can cause harmful micro- and nanoplastics to shed into food. Therefore, it is recommended to hand-wash these containers instead of dishwashing them to minimise exposure to heat.
Another option is the Snapware set, which comes in a variety of shapes and sizes, with larger containers for storing leftovers and smaller ones for dressings or sauces. The Snapware lids are leakproof and easy to snap shut.
When storing leftovers, it is important to follow food safety guidelines to prevent foodborne illness. Leftovers should be refrigerated promptly, ideally within four hours, and can be kept in the refrigerator for 3 to 4 days or frozen for 3 to 4 months. When reheating leftovers, ensure that they reach a temperature of 165° F to guarantee food safety.

Aluminium foil
For bread, wrapping the loaf tightly in aluminium foil can help extend its shelf life by up to 6 months in the freezer. Similarly, cakes can be stored in the freezer using aluminium foil, helping to preserve their frosting.
When using aluminium foil, it is important to maximise its reuse. For example, foil can keep salad greens, celery, and broccoli crisp for weeks when wrapped tightly and refrigerated. However, it is worth noting that while foil can be recycled, many recyclers do not bother to do so. Therefore, it is essential to extend the lifespan of foil by reusing it as many times as possible.
