Type 7 plastic is a catch-all category for plastics that don't fit into the other six recycling categories (1-6). This means it includes a variety of plastics with different chemical compositions, properties, and recyclability.
Because of the diversity within this category, type 7 plastics can be made up of:
- Recyclable Plastics: Some type 7 plastics are recyclable, although their recyclability often depends on local facilities and the specific resin used.
- Non-Recyclable Plastics: Many type 7 plastics are difficult or impossible to recycle through conventional methods.
- Biodegradable Plastics: Some newer type 7 plastics are made from bio-based materials and are designed to be biodegradable or compostable under specific conditions.
- Multi-Layer or Mixed Resin Plastics: This refers to products made by combining multiple different types of plastics or layering them together.
Here's a breakdown to further illustrate:
Feature | Description |
---|---|
Definition | A "catch-all" category for plastics not categorized as types 1 through 6. |
Composition | Can include a variety of plastics like polycarbonate, acrylic, nylon, and bio-plastics. Often contains multiple resins. |
Recyclability | Varies greatly. Some are recyclable, but many are not accepted by local recycling programs. |
Common Uses | Baby bottles, water cooler bottles, plastic CDs, eyeglasses, computer cases, some food containers, car parts, exterior lighting fixtures. |
Health Concerns | Some type 7 plastics, particularly those containing bisphenol A (BPA), have raised health concerns due to potential leaching of chemicals. |
Examples of Items Made from Type 7 Plastic:
- Baby bottles (often made with polycarbonate containing BPA, though BPA-free alternatives are increasingly common)
- Water cooler bottles
- Plastic CDs and DVDs
- Eyeglasses
- Computer cases
- Car parts
- Exterior lighting fixtures
Important Considerations:
- Check Local Recycling Guidelines: Always check with your local recycling program to determine if they accept specific type 7 plastics.
- Look for BPA-Free Alternatives: If you are concerned about BPA, look for products specifically labeled as "BPA-free."
- Consider Alternatives: Where possible, consider using products made from more easily recyclable materials like glass, aluminum, or certain types of plastic (like PET or HDPE) that are widely recycled.
- Understanding Symbols: The #7 plastic symbol may include abbreviations for the specific plastic type within it (e.g., "OTHER," "PC" for polycarbonate, or "PLA" for polylactic acid, a bioplastic).
In summary, type 7 plastic is a mixed bag, requiring careful consideration of its specific composition and recyclability before disposal.
