Creative Ways To Upcycle Plastic Caps For Fun And Function

how to repurpose non recyclable plastic caps

Plastic bottle caps are a significant source of pollution, especially in the oceans, and are often not recycled properly. While some recycling programs accept caps, others do not, due to the different types of plastic resin used in caps and bottles, and the small size of caps, which can cause them to get lost during the recycling process. To avoid this, some programs require caps to be removed from bottles, while others require them to be left on. To avoid your caps ending up as waste, it's important to check your local program's rules. If your local program doesn't accept caps, you can try to repurpose them for various creative and practical applications, such as using them as containers for starting seeds, or for organising small household items.

Use plastic caps for storage

Plastic caps, often designed for single use, can be reused and repurposed for storage in a variety of ways. Repurposing plastic caps can help to reduce waste and find innovative uses for them in your home.

One way to use plastic caps for storage is to transform them into containers for small items. First, clean and dry the caps thoroughly to remove any residue. Then, you can use the caps to store and organise various small household items. For example, in the bathroom, you can use them to store hairpins, rubber bands, or small jewellery pieces. In the office, they can be used to organise paper clips, push pins, or binder clips. In a craft room, keep beads, buttons, or sewing needles sorted. You can even use them in the laundry room to measure out powdered detergent, or in the kitchen to scoop and portion dry goods like rice or flour.

Another way to use plastic caps for storage is to create educational aids for children. Write letters or numbers on the caps to assist with literacy and numeracy skills. You can also paint the caps in different colours for sorting and matching activities, or use them for stacking toys to develop fine motor skills.

Additionally, you can use plastic caps for seed starting. Puncture small holes at the bottom of each cap to allow excess water to escape. Then, fill the caps with a seed-starting mix, plant your seeds, and water them appropriately. Place the caps in a sunny location and keep the soil moist until the seedlings are ready for transplantation.

It's important to note that plastic caps are made from different types of plastic resins, such as polypropylene (#5 plastic) or high-density polyethylene (#2 plastic), and may not be accepted by your local recycling program. However, there are creative ways to repurpose them for storage and organisation.

Create artwork with plastic caps

Plastic bottle caps can be used to create artwork in a variety of ways. One way is to create a butterfly mosaic using bottle caps. First, seal the front surface of a plywood board with two coats of white paint. Then, make a rough sketch of a butterfly on the plywood using a light pencil. Paint the butterfly using acrylic craft paint. The paint job doesn't have to be perfect as it is only meant to add a pop of colour in the spaces that peek through between the bottle caps. Paint the remaining background area as well. After the paint is dry, start filling in the spaces with bottle caps to create your butterfly mosaic. Once you have an arrangement that you like, adhere the bottle caps one by one to the plywood using E-6000 (in a well-ventilated area) or a hot-glue gun.

You can also create artwork using plastic bottle caps by assembling them into realistic images. American artist Mary Ellen Croteau uses this method, employing the caps' original colours to create realistic shading and hues in her images. Alternatively, you can create a grid using plastic bottle caps and use this grid to represent an image, such as a human face. You can use Adobe Illustrator software to design the image and create the grid. Then, paint each of the stages in colours, following the image you have chosen.

Another way to create artwork with plastic caps is to use them as stamps. You can cut out circles from cardstock or cardstock-weight patterned paper and stick them to the inside of the caps using ultra-thin glue dots. This will create a dramatic visual change in your art piece. You can also pre-drill holes in the caps and screw them into a piece of wood to create a sculpture or 3D artwork.

If you are looking for a more functional form of art, you can create a pincushion using a plastic detergent cap. Simply clean and dry the cap thoroughly, then fill it with pincushion filling and attach a fabric top. You can also use plastic detergent caps as measuring scoops for various household tasks, such as measuring out powdered detergent, scooping dry goods like rice or flour, or portioning pet food accurately. Label the caps with the corresponding measurements for convenience.

Make children's learning games

Plastic bottle caps are often non-recyclable and can be extremely harmful to the environment if not disposed of properly. They are also small enough to be choking hazards for children. However, they can be repurposed in a variety of ways to make children's learning games. Here are some ideas:

Literacy and Numeracy Skills

Write letters or numbers on the caps to assist children with their literacy and numeracy skills. Children can match lowercase to lowercase letters, uppercase to uppercase letters, or lowercase to uppercase letters. You can also use the caps to help children learn how to spell and recognize their names. For instance, you can write letters on the caps with Sharpies and use them on letter-sorting mats. Alternatively, you can use printable letters or stickers.

Sorting and Matching Activities

Paint caps in different colours for sorting and matching activities. You can also use stickers to create a thematic game. For instance, you can put two of each sticker on the top of the caps, turn them over, and play a matching game.

Fine Motor Skills

Use plastic bottle caps for stacking exercises to help children develop fine motor skills. You can also add a basket of plastic lids to your block centre and let children use them in their block creations.

Counting Activities

Use plastic lids as counters for counting activities. You can add stickers or pictures to the tops of the lids to make it more interesting for children. Bottle caps are especially useful when using ten frames for one-to-one correspondence practice.

Sensory Bins

Add bottle caps to a sensory bin filled with another material, such as rice, sand, beans, or corn. Children can then find matching lids or match colours. You can also fill the bottle caps with different materials and have children guess what's inside by shaking them.

Outdoor Games

Create a tic-tac-toe game using a large black circle made from paper or cardboard as the board, and mark plastic bottle caps with Xs and Os as the pieces.

Music and Creativity

Seal two caps together with strong tape or glue to make homemade instruments and foster musical creativity in children.

Start seeds in plastic caps

Plastic caps, such as those from detergent jugs, can be repurposed in various ways to start seeds. This method is affordable and eco-friendly, and can be used to kickstart your garden. Here is a step-by-step guide to starting seeds in plastic caps:

Prepare the Caps:

First, collect and clean the plastic caps thoroughly to remove any residue. This is an important step to ensure that your seeds have a clean environment to grow in.

Create Drainage:

Using a sharp object, puncture small holes at the bottom of each cap. This step is crucial as it allows excess water to escape, preventing waterlogging and potential root rot.

Add Soil and Seeds:

Fill the caps with a seed-starting mix or regular soil. Then, plant your seeds and water them appropriately. Make sure to follow the specific instructions for the seeds you are planting, as different seeds have varying requirements for light and soil conditions.

Monitor Growth:

Place the caps in a sunny location, preferably near a window, to ensure the seedlings receive adequate light. Keep the soil moist to provide the necessary hydration for germination. Remember to check on your seeds regularly and transplant them to larger pots once they have grown sufficiently.

Additional Tips:

  • You can use plastic cups or bags to create mini-greenhouses for your seeds, providing warmth and moisture to speed up sprouting.
  • Mark the caps or containers with the type of seeds planted and their specific needs, such as light or soil requirements.
  • Experiment with different varieties of seeds suited to your climate zone, but always start with seeds recommended for your zone to ensure the best results.

Make a pincushion

Plastic caps can be repurposed in many ways, one of which is to make a pincushion. Here is a step-by-step guide on how to make a pincushion from a plastic cap:

Firstly, you will need to clean and dry the plastic cap thoroughly. You can use any plastic cap, but most people use caps from soda bottles. Next, you will need to gather the materials for the pincushion. This includes the fabric for the cushion, embroidery thread, and stuffing for the cushion. You can use regular stuffing or get creative like one person who used crushed walnut shells for the stuffing.

Now, you are ready to start making the pincushion. Take your fabric and cut it into a circle that is slightly larger than the plastic cap. Place the cap in the centre of the fabric and gather the edges of the fabric around the cap, securing it with a running stitch. You can then add some embroidery to the pincushion. One suggestion is to make a daisy stitch in the centre, by making a bunch of isolated chain stitches. You can then add some arrow-like stitches all around it and use the same stitch along the bottom.

Finally, you can add some velcro dots to the bottom of the pincushion so that you can stick it to your sewing machine. Alternatively, you can tie a piece of round elastic through two holes in the cap and tie it to fit your finger, creating a finger pincushion.
