Evaluation of paper straws versus plastic straws: Development of a methodology for testing and understanding challenges for paper straws
This study developed a methodology for testing the performance of paper straws as alternatives to plastic straws, evaluating their structural integrity, taste neutrality, and environmental impact under realistic use conditions. The work addresses the need for objective evaluation of plastic straw alternatives as regulations drive substitution away from single-use plastics.
All-natural, hydrophobic, strong paper straws based on biodegradable composite coatings
Researchers developed an all-natural paper straw coated with a biodegradable mixture of sodium alginate, cellulose nanofibers, and stearic acid that avoids the microplastic problem of traditional plastic-coated straws. The coating made the straws water-resistant for over three hours while maintaining good strength, and the straws fully biodegraded in soil within about 45 days. The study offers a practical alternative to plastic straws that does not contribute to microplastic pollution during breakdown.
Evaluation and future development direction of paper straw and plastic straw
This review evaluates the environmental trade-offs of replacing plastic straws with paper straws, examining lifecycle impacts, material properties, and waste management outcomes. The authors find that while paper straws reduce persistent plastic pollution, their production and disposal also carry environmental costs, and that neither option is entirely without impact.
All-natural, hydrophobic, biodegradable cellulose-based straws through simultaneous esterification and filling with stearic acid for cold beverages
Researchers developed a biodegradable, all-natural straw made from bleached bamboo fibers and stearic acid as an alternative to plastic straws that generate microplastics.
