What You'll Learn
Sorting and cleaning PET plastics at home
Sorting and cleaning your PET plastics at home is a great way to ensure you are recycling correctly and reducing waste. Here is a step-by-step guide to help you get started:
Sorting:
First, identify which plastics are PET. Look for the #1 recycling symbol on the product, this is usually found on the bottom of the plastic item. It is important to separate PET plastics from other types of plastic as they have different recycling processes. Thermoformed PET plastics, such as egg cartons and fruit containers, are chemically different from PET bottles and cannot be recycled in the same load. Check with your local recycling provider to see if they accept thermoformed PET plastics and if there are any specific instructions for their recycling.
Removing Attached Items:
Before cleaning, remove any items that are physically attached to the PET plastic bottles or containers. This includes plastic cups on the bottom of carbonated beverage bottles (known as base cups), labels, and caps. Adhesives used for labels can be particularly tricky, so try to remove as much as possible to avoid gumming up recycling machinery.
Cleaning:
Rinse or wash the PET plastics with water to remove any remaining residue or contaminants. Ensure they are clean and dry before placing them in your recycling bin. This step is crucial as it helps prevent the growth of bacteria and keeps your recycling load hygienic.
Drying:
After cleaning, dry the PET plastics thoroughly. Place them in a well-ventilated area or use a cloth to speed up the drying process. It is important that the plastics are completely dry before being placed in the recycling bin to avoid potential issues during the recycling process.
By sorting and cleaning your PET plastics at home, you are contributing to a more sustainable future and reducing the amount of waste that ends up in landfills. Remember to also check with your local recycling company to understand their specific guidelines and ensure your efforts align with their processes.

Removing items physically attached to PET bottles
Removing items that are physically attached to PET bottles is an important step in the recycling process. This process can be done at home, but it requires some time and effort. Here are some ways to remove these items and prepare your PET bottles for recycling:
Plastic cups on the bottom of carbonated beverage bottles, known as base cups, can be removed by softening the plastic with heat. Place the bottle upside down in a container and fill it with boiling water. Wait for a couple of minutes, then remove the bottle. The plastic base cup should now be soft enough to be removed easily. You can use a small screwdriver or the handle of a teaspoon to pry it off gently without damaging the PET bottle.
Labels can be removed by soaking the bottle in hot water. Use a scrubber or sponge to remove any remaining glue. If there is still glue residue, a mild bleach solution (1 teaspoon of bleach per quart of water) can be used to sanitise the bottle and remove any remaining glue or residue. Soak the bottle in the bleach solution for around 10 minutes, then gently shake the bottle before dumping out the liquid.
Caps and rings are typically made from polypropylene plastic (PP) and can be removed by hand. If the cap is not a screw top, it can be softened with heat and pried off gently with a small screwdriver. An electrostatic separator can be used to separate the PET bottle from any aluminium that may be present as a result of bottle caps. This step is usually done at a reclaiming facility, but if you have access to an electrostatic separator, you can use it to ensure a more comprehensive removal of attached items.
It is important to rinse out any residue or liquids originally stored in the PET bottle and to wash the bottle in hot, soapy water. Use a scrubber or sponge to remove any caked-on residue, and let the bottle dry completely before placing the lid back on to prevent bacterial growth.

Checking which #1 plastics your recycling company accepts
When it comes to recycling PET plastic at home, it's important to first check which #1 plastics your recycling company accepts. While most curbside recyclers accept PET plastic bottles, it's worth noting that not all types of #1 plastics can be recycled together. For example, PET bottles and thermoformed packaging containers, such as egg cartons and fruit containers, are both categorized as #1 plastic but have different chemical compositions and melting temperatures, so they require separate recycling streams.
To ensure you're recycling your #1 plastics correctly, start by contacting your local recycling company. Ask them specifically about the types of #1 plastics they accept and any special instructions for their collection and preparation. Some companies may have specific guidelines for handling and sorting these materials. It's important to follow these instructions carefully to avoid contaminating the recycling stream.
Additionally, keep in mind that not all recycling programs accept thermoformed PET plastics. These plastics are used for packaging items like salad greens, berries, bakery goods, and medical supplies. Due to their unique properties, they often require separate recycling facilities. If your local recycling program doesn't accept these materials, inquire about alternative drop-off locations or recycling centers that can handle thermoformed PET plastics.
By taking the time to understand the specific recycling guidelines in your area and separating your #1 plastics accordingly, you can play a crucial role in increasing the circularity of PET recycling. Remember, recycling companies often update their accepted materials and guidelines, so it's a good idea to stay informed and adapt your recycling habits as needed.

Buying products made with recycled #1 plastics
When buying products made from recycled plastics, you're contributing to the reduction of virgin plastic production and strengthening the market for recycled plastics. Recycled plastic is much more eco-friendly than sourcing raw materials, and it's just as good in terms of quality and longevity. In fact, by choosing recycled plastics, you lose nothing in terms of quality or longevity compared to virgin plastics. Most plastic products can be made from recycled plastic.
Common products made from recycled plastics include clothing, toys, tableware, shoes, bags, and home furnishings like chairs and rugs. For example, Green Toys sells toys that are made from 100% recycled materials, including recycled milk jugs and yogurt containers. Similarly, the Buffy Cloud comforter is made from BPA-free recycled PET fibres that come from plastic bottles, preventing approximately 50 plastic bottles from landing in the trash.
You can also look for recycled plastic in less obvious places, like in your electronics. For example, Gomi, a company based in Brighton, UK, makes portable and wireless chargers from 'non-recyclable' waste, and even their batteries are reclaimed and repurposed from waste electronics. If you're looking for something to protect your phone, Lifeproof makes the eco-conscious WAKE case for iPhones, which is made from sustainably obtained, 85% ocean-based recycled plastic.
By choosing to buy products made from recycled plastics, you're creating a market and a demand for more sustainable goods. This contributes to a social, political, and economic context that supports cleaner consumerism and the transition away from a throwaway society.
