Synthetic fibers are more polluting than natural fibers.

CONTESTED PARTIAL
Recorded sources
6 sources for · 1 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that synthetic fibers are more polluting than natural fibers?

Partly. Several reviews describe synthetic fibers and polymers as polluting and natural fibers as more environmentally friendly, though mostly in composites or specific applications. One review notes that extracting natural bamboo fibers also generates highly polluting acid and base waste, so the comparison is not one-sided.
