What Plastic Recycling Symbol Means: How to Choose Safer Plastic
Plastic is ubiquitous in the modern world, from food packaging to household items to electronics. While it’s convenient and inexpensive, plastic can also be harmful to our health and the environment. That’s why it’s important to understand the different types of plastic and how to choose safer options.
The Plastic Recycling Symbol
Most plastic items have a recycling symbol with a number from 1 to 7 inside it. This symbol indicates the type of plastic used in the product.
- PET or polyethylene terephthalate is commonly used in food and drink packaging, such as water bottles and soda bottles. PET is considered to be relatively safe, but it’s important to avoid reusing it, as this can lead to the leaching of toxic chemicals.
- HDPE or high-density polyethylene is used in a variety of products, including milk jugs, detergent bottles, and toys. HDPE is considered to be safe and recyclable, making it a good choice for everyday use.
- PVC or polyvinyl chloride is used in a variety of products, including pipes, siding, and food packaging. PVC is considered to be harmful to human health and the environment, so it’s best to avoid it if possible.
- LDPE or low-density polyethylene is used in a variety of products, including plastic bags, wrapping film, and food packaging. LDPE is considered to be relatively safe, but it’s not very environmentally friendly, as it’s not recycled very often.
- PP or polypropylene is used in a variety of products, including yogurt cups, ketchup bottles, and food storage containers. PP is considered to be safe and recyclable, making it a good choice for everyday use.
- PS or polystyrene is used in a variety of products, such as disposable cups, foam packaging, and insulation. PS is considered to be harmful to the environment and difficult to recycle, so it’s best to avoid it if possible.
- Other is used for all other types of plastic that don’t fit into the other categories. This includes new plastics, bioplastics, and mixed plastics.
Choosing Safer Plastic
When choosing plastic products, it’s best to opt for those made from HDPE, PP, or LDPE. These plastics are considered to be relatively safe and recyclable. Avoid products made from PVC or PS, as these plastics are considered to be harmful to human health and the environment.
Here are some additional tips for choosing safer plastic:
- Avoid heating plastic, as this can lead to the leaching of toxic chemicals.
- Don’t reuse plastic food packaging, unless it’s specifically designed for reuse.
- Choose glass, metal, or paper packaging whenever possible.
