Plastic waste is a pressing issue, with single-use plastics being a major contributor. However, making the most of what you already have is a core principle of sustainability. There are many ways to reuse plastic containers, such as plastic bottles and bags, at home. For example, plastic bottles can be cut and used as planters for flowers and herbs, while plastic bags can be reused as wastebasket liners or cooking utensils. Plastic containers can also be reused for storage, such as keeping tiny tools and craft supplies, or as mixing containers for sauces or salad dressings. It is important to note that not all plastics are safe for reuse, especially when exposed to heat, so it is recommended to check the Resin Identification Code on the bottom of containers to ensure they are safe for reuse.

What You'll Learn

Plastic containers can be reused as planters for flowers and herbs
Firstly, it is important to disinfect old plant pots to prevent the spread of fungal and other diseases to new plants. You can then reuse these larger containers to repot plants that are outgrowing their current home. For example, you can grow potatoes in a container that formerly housed a larger plant, like a tree.
If you are looking to add colour to your garden, you can create a permanent planting hole by digging a hole and inserting a black plastic pot that is larger than the containers you plan to swap out. You can then easily sink and lift seasonal plants as needed. The black colour will help the pot blend in with the surrounding foliage.
You can also use smaller plastic containers as shakers for fertilizer, animal repellent, and other granular materials. Simply scoop up what you need and wave the container to start the flow.
For plants that tend to spread aggressively, like mint, you can sink the entire container into the ground to achieve the look of an in-ground herb without the worry of invasion into other areas of the garden.
Finally, you can use plastic containers as mini greenhouses for young plants. Invert small pots over the plants to protect them from birds, rabbits, and other critters, as well as providing extra warmth and frost protection.

Plastic containers can be used for storing food
Plastic containers can be reused to store food, but there are some important considerations to keep in mind. Firstly, it is recommended to avoid using plastic containers for hot food or drinks, as heat can cause chemicals from the plastic to leach into your food or drink. This includes avoiding microwaving plastic containers. Instead, plastic containers are best suited for storing cold or room-temperature food and drinks, such as leftovers, dried goods, or meal-prepped vegetables.
When reusing plastic containers for food storage, it is important to properly clean and sterilize them to prevent the growth of bacteria and the contamination of food. This can be done by soaking the containers in warm, soapy water, gently cleaning them with a sponge or brush, and then allowing them to air dry. Additionally, spraying the containers with isopropyl alcohol can help ensure they are sanitized. To prevent food stains and the degradation of the plastic, it is recommended to spray the containers with a non-stick cooking spray before adding food, especially if the food is acidic.
While plastic containers can be reused for food storage, it is worth noting that they do have a shelf life and will eventually break down into microplastics, which can contaminate food. As an alternative, glass, stainless steel, or ceramic containers are recommended for food storage as they are safer, tend to last longer, and are better for the environment. However, plastic containers can be a more convenient and affordable option for storing food, especially when it comes to takeout containers.
To extend the life of plastic containers and reduce waste, it is recommended to follow proper care instructions. This includes avoiding exposing the containers to high temperatures, harsh cleaning chemicals, or sharp objects that could scratch the surface and create crevices for bacteria to grow. Additionally, it is important to periodically inspect the containers for any signs of degradation, such as cracks or cloudiness, and dispose of them responsibly when they can no longer be safely reused.
Overall, plastic containers can be reused for food storage, but it is important to be mindful of the potential risks associated with plastic degradation and chemical leaching. By following proper cleaning and care instructions, you can safely reuse plastic containers for storing cold or room-temperature food and reduce waste. However, for a more sustainable and long-lasting option, glass, stainless steel, or ceramic containers are recommended.

Plastic containers can be used for storing craft supplies
Plastic containers are a great way to store and organise craft supplies. They are versatile and can be used to store a variety of items, from art supplies to sewing kits.
For art supplies, you can use plastic containers to organise crayons, markers, feathers, beads, and paint jars. Label each container and store them in a drawer to keep your art supplies neat and tidy. You can also use plastic containers to store spools of ribbon and string. To take it a step further, cut small holes in the container and feed the ribbon through, creating a homemade dispenser that keeps the ribbons tangle-free.
For sewing supplies, plastic containers can be used to store buttons, needles, threads, and other notions. Keep your sewing kit organised and easily accessible by using multiple containers for different items. You can also use plastic containers to store fabric scraps, keeping them clean and tidy until you're ready for your next project.
Smaller plastic containers, such as pill bottles or lipstick containers, can be useful for storing tiny items like paper clips, staples, and other desktop essentials. Keep your workspace organised and clutter-free by utilising these small containers for easy access to your most-used items.
Additionally, plastic containers can be used to create an emergency craft kit. Fill a larger container with essential supplies like glue, scissors, a pencil sharpener, an eraser, and a small notebook. This way, you have a portable kit ready for any last-minute projects or creative endeavours on the go.
By reusing plastic containers for craft supply storage, you're not only keeping your craft space organised but also reducing waste and contributing to a more sustainable lifestyle.

Plastic containers can be used for storing tiny tools
Plastic containers are versatile and can be reused in numerous ways to organise and store tiny tools. For instance, old ice cube trays can be used to store small items such as thumbtacks, nails, screws and buttons. Each cube can be designated for a different item using a permanent marker. Plastic containers with lids, such as ice cream tubs, can be used to store small toys, kitchen gadgets, and other small items.
In a home office setting, plastic storage containers can be used to organise desk drawers and store office supplies. They can also be used in conjunction with shelving units to create additional storage space. For example, plastic containers can be placed on shelves or in drawers to store paper files, backup supplies, and other small items.
Plastic containers can also be used to create a stylish and functional space in a home office. Vintage, retro, or antique pieces can add charm and character to the room. For instance, a sleek plastic bathroom makeup storage caddy can be used to store pens, pencils, and other desk clutter. Old cassette cases can be repurposed to store gift cards, business cards, or customer loyalty cards.
Additionally, plastic containers can be used for gardening purposes. Clamshell-style plastic containers that berries are typically packaged in can be used as mini-hothouses for seedlings. These containers come in various sizes and provide an effective way to nurture young plants. Plastic containers help create a controlled environment for seedlings, protecting them from extreme temperatures and providing easy access for watering and care.
