Which statement is true about the recycling of plastics?

The statement regarding the recycling of plastics that is true is that only certain types of plastics are recycled. This reflects the reality of plastic recycling, where not all plastics are accepted in recycling programs due to variations in plastic types, compositions, and the economic feasibility of recycling them.

Certain plastics, such as PET (often used for water bottles) and HDPE (common in containers), are widely recycled, while others, like polystyrene (used in some packaging and disposable utensils) or certain types of multi-layer plastics, often are not accepted because they require different processing methods or have low market demand for recycled material. This selective recycling process can vary by region and depends on local recycling facilities and capabilities, which further underscores the truth of this statement.

The other options present a generalized view of plastic recycling that does not accurately capture the complexities involved, such as the misconception that all or most plastics can be easily recycled, or the incorrect assertion that plastics are easily composted, which is not the case for most plastic types.
