Plastic soft-drink bottles are commonly made of polyethylene terephthalate (PET).
Solid-waste management strategies for plastic waste differ significantly in their environmental impacts and effectiveness:
- Landfills: When well-managed, landfills can contain plastic waste and prevent it from spreading into the environment. However, they do not eliminate the persistence of plastic, as synthetic polymers are largely nonbiodegradable and remain in the environment for centuries.12
- Incineration: This process reduces the volume of plastic waste, but it requires careful emissions controls to manage the release of pollutants. Furthermore, incineration results in the emission of carbon dioxide, a potent greenhouse gas, and can raise public health concerns when synthetic materials are burned.13
- Recycling: While recycling can reduce the demand for new plastic production, it is often hindered by contamination, material properties, and economic factors. Because plastics are difficult to reprocess efficiently, recycled materials often have disadvantages compared to virgin plastics, and recycling rates remain relatively low globally.142
Ultimately, because these methods have distinct trade-offs, many organizations emphasize reducing plastic consumption and designing products for reuse as more sustainable alternatives.1
