PLA (polylactic acid) straws are derived from renewable resources like corn starch and offer a compostable alternative to petroleum-based plastic straws. Unlike traditional plastic, which can persist in the environment for hundreds of years, PLA straws break down in commercial composting facilities—typically within 90 to 180 days.
However, they require specific heat and moisture conditions to decompose properly, meaning they won’t break down effectively in backyard compost or landfills.
While not perfect, PLA straws offer a clear environmental improvement over conventional plastics—especially when part of a broader compostable packaging strategy.
