HD in recycling typically refers to High-Density Polyethylene (HDPE), a commonly recycled plastic.
Understanding HDPE
HDPE, also known as "PE-HD", is a thermoplastic polymer widely used in both consumer and industrial applications. Its popularity in recycling stems from its desirable properties:
- High tensile strength.
- Impact resistance.
- Strong strength-to-density ratio [1].
Common Uses of HDPE
HDPE is used to make a variety of products, including:
- Milk jugs.
- Detergent bottles.
- Plastic bags.
- Toys.
- Some plastic pipes.
Why Recycle HDPE?
Recycling HDPE offers numerous benefits:
- Resource Conservation: Reduces the need to manufacture new plastic from raw materials.
- Energy Savings: Requires less energy to recycle HDPE compared to creating new plastic.
- Waste Reduction: Diverts plastic waste from landfills.
Identifying HDPE for Recycling
HDPE is typically identified by the recycling symbol number 2 inside the chasing arrows triangle. Check the bottom of plastic containers for this symbol.
