- PET (Polyethylene Terephthalate): Used for bottles.
- HDPE (High-Density Polyethylene): Used for containers.
- PVC (Polyvinyl Chloride): Used for pipes.
- PP (Polypropylene): Used for packaging.
- PS (Polystyrene): Used for disposable items.
- LDPE (Low-Density Polyethylene): Used for bags.
- ABS (Acrylonitrile Butadiene Styrene): Used for toys.
- PC (Polycarbonate): Used for optical discs.
Types of Rubber:
- Natural rubber: Derived from rubber trees.
- Synthetic rubber: Manufactured.
