A reported 29 percent reduction means less material should be rejected, though nearly one item in five remains a costly problem.

What happened
Tucson reported that contamination in its recycling stream declined by 29 percent to roughly 19 percent. Contamination includes plastic bags, food, liquids and other materials that do not belong in curbside recycling and can damage equipment or spoil otherwise marketable loads.
Why it matters in Tucson
A lower contamination rate can reduce processing costs and improve the value of recovered material. The remaining rate is still significant, showing that recycling labels and packaging claims continue to confuse residents. Reducing unnecessary packaging and reusing materials remain more effective than relying on recycling alone.
What to watch next
The city should publish a consistent year-over-year method, identify the most common contaminants and target education accordingly. Residents need simple, Tucson-specific instructions because accepted materials differ among communities and processors.
