Material Standards Affect Degradability: Some paper straws are made of composite materials (such as paper + coating). The degradability of these materials is significantly reduced, and they may even be difficult to decompose naturally due to the presence of coating components (such as plastic).
Environmental Costs of the Production Process: Paper production itself generates pollution emissions, including energy consumption and wastewater discharge. If the production process of paper straws does not strictly adhere to environmental standards, its overall environmental impact may offset its degradation advantages.
Life Cycle Perspective: Environmental friendliness requires comprehensive consideration of the entire process of a product, from raw material extraction, production, transportation, use to disposal. For example, if paper straws experience increased carbon emissions due to long transportation distances, or if high production energy consumption offsets their degradation advantages, their environmental friendliness may not be as expected.
