There are many different types of plastics, generally categorized into seven major types. These plastics vary based on their composition, size, colour, applications, and appropriate disposal methods. Understanding these differences is crucial to determine whether a specific plastic material or item is recyclable.
Understanding the Plastic Codes:
- PETE (Polyethylene Terephthalate): Commonly used in soft drink bottles, condiment bottles, and peanut butter containers.
- HDPE (High-Density Polyethylene): Found in milk and juice bottles, detergent bottles, and shampoo bottles.
- PVC (Polyvinyl Chloride): Used in pipes, toys, and garden hoses.
- LDPE (Low-Density Polyethylene): Typically used in ice cream lids, garbage bags, sandwich bags and industrial applications such as stretch film and shrinkwrap
- PP (Polypropylene): Found in bottles, tubs, and clothing.Â
- PS (Polystyrene): Common in cups, foam food trays, and packing materials.
- Other Plastics: This category includes plastics that are typically not recyclable through regular programs.
What Can Be Recycled?
Plastics with codes 1, 2, and 5 are typically accepted by most Australian councils. However, recycling processes can vary by location, so it's important to check with your local council for specific guidelines.
What Can't Be Recycled?
Plastics with codes 3, 4, 6, and 7 are generally more difficult to recycle. Expanded polystyrene foam (code 6) and plastic bags (often codes 2 or 4) cannot be recycled through kerbside bins. For accurate disposal, you can refer to the Australasian Recycling Label (ARL) for further instructions.
A product may come in several packaging parts. This labelling system tells you what to do with each part.
The Significance of Recycling Procedures
Recycling procedures vary depending on your location. These procedures dictate which materials can be recycled and the specific methods for recycling them, such as plastic bags and stretch films. Your first step is to reach out to your local recycling authority to understand the processes in your area.
Separating the Recyclables
Some recycling programs require you to separate different materials like glass, aluminium, and plastics into different bins, while others may ask you to separate paper from other recyclables. Be sure to familiarize yourself with your local recycling system to ensure you're separating items properly.
Major Types of Recyclable Plastics
-
PET: PET is one of the most recycled plastics worldwide, particularly for plastic bottles. Countries like India, Europe, and South Korea have recycling rates over 50%, while others are still catching up. Recycled PET is often used in fashion products like polar fleece, backpacks, and rugs. PET is processed into flakes and spun into yarn for textile applications. PET will Display a type one recycling code 1 PETE
-
LDPE: While LDPE is widely used, especially in plastic bags, it is difficult to recycle. Plastic bags often get tangled in recycling equipment, disrupting the process. LDPE recycling is not economically viable in many regions, though scientists are working on innovative, eco-friendly solutions. LDPE will displayu the Type 4 recycling code.Â
-
HDPE: HDPE is one of the easiest plastics to recycle. Most recycling facilities accept HDPE, and it has a recycling rate of about 30% in the US. This plastic is used for non-food bottles like those for detergent and motor oil. HDPE is often downcycled into durable products such as plastic lumber, park benches, and curbs. HDPE will display the type 2 recycling code.Â
-
PP: Polypropylene (PP) is widely used but challenging to recycle. Recycled PP can have a strong odor from its previous contents, and it often ends up in lower-value products like plastic lumber, park benches, and automobile parts. Polypropylene will display the type 5 product code.Â
Using a Recycling Bin Efficiently
When recycling, it's important to place items in the appropriate bins. For example, avoid putting plastic bags in recycling bins as they can jam equipment. Be mindful of the guidelines for your local recycling program.
How are these recycled plastics used in packaging?
At MPS Packaging Australia, sustainable packaging solutions are a key focus, and the use of recycled materials plays a significant role in reducing environmental impact.
Recycled PET bottle flakes are commonly used in PET strapping, providing a durable and eco-friendly option for securing goods. PET strapping, made from these recycled flakes, is used in a variety of industries to ensure load stability and product security during transport.
HDPE and LDPE plastics, after being recycled, are typically remilled into new materials that are used for manufacturing plastic sheeting, plastic bags, and other industrial applications. These products are designed for situations where food contact is not a concern, making them ideal for packaging and general industrial use.
Recycled PP, on the other hand, is often processed into PP strapping. This type of strapping, made from recycled polypropylene, is widely used to secure products in industries like logistics and manufacturing, ensuring efficient and sustainable packaging.
By utilizing these recycled materials, MPS Packaging Australia contributes to a more sustainable packaging industry while maintaining the strength and reliability needed for secure transportation and storage.
Final Thoughts
As awareness about sustainability grows, the global recycling rate continues to rise. It is essential for both plastic manufacturers and consumers to be mindful of the different types of plastics and ensure that recyclable materials, like plastic bags and stretch wraps, are properly processed. By doing so, we can all contribute to a more sustainable future.
