ClearOptimizing multilevel interactions of paper straws using modified cellulose nanocrystal-based coatings to enhance PLA crystallization and microplastic capture efficiency
Researchers developed a novel coating for paper straws using modified cellulose nanocrystals combined with PLA to improve durability and water resistance. The coating also demonstrated the ability to capture microplastics from beverages during use. The study offers a dual-benefit approach: creating a more practical paper straw alternative while simultaneously reducing microplastic exposure from drinking.
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.
Biodegradable, Water‐Resistant, Anti‐Fizzing, Polyester Nanocellulose Composite Paper Straws
Researchers developed a biodegradable paper straw coated with poly(butylene succinate) and cellulose nanocrystals that resists water absorption and prevents the fizzing typical of conventional paper straws in carbonated drinks. Unlike PLA-coated alternatives, the coating is fully ocean-degradable and the nanocrystals improved coating adhesion.

This study evaluated bio-based alternatives to conventional plastic drinking straws, assessing the environmental footprint of paper and polylactic acid straws versus plastic and comparing their functional properties including user experience.
A hydrophobic and degradable straw based on the ethyl cellulose-coated bacterial cellulose
Researchers developed a hydrophobic and biodegradable straw made from ethyl cellulose-coated bacterial cellulose as a microplastic-free alternative to conventional disposable plastic straws. The cellulose-based straw achieved the hydrophobicity needed for beverage use while remaining biodegradable, offering a sustainable substitute that avoids microplastic shedding during use and disposal.
Ultrastrong, Hydrostable, and Degradable Straws Derived from Microplastic-Free Thermoset Films for Sustainable Development
Researchers developed strong, moisture-stable drinking straws from all-natural thermoset materials derived from plant-based resins, demonstrating that the resulting straws are microplastic-free, fully biodegradable, and mechanically superior to paper straws which collapse in beverages.
Investigating interface adhesion of PLA-coated cellulose paper straws: Degradation, plant growth effects, and life cycle assessment
Researchers developed polylactic acid-coated cellulose paper straws as an alternative to single-use plastic straws and evaluated their environmental impact. The straws decomposed 35-40% within 4 months in soil and compost, though microplastics were detected in surrounding soil and plant tissues. Life cycle assessment showed that the manufacturing improvements reduced the ecological footprint compared to conventional plastic straws, though the release of microplastics during degradation warrants further study.
Production of Cost-Effective Biodegradable Straw
Researchers developed a biodegradable drinking straw made from natural, chemical-free materials as an alternative to plastic straws. Plastic straws are a common source of single-use plastic pollution and potential microplastic generation in marine environments.
An ethyl cellulose-coated bacterial cellulose based hydrophobic and degradable straw-like materials towards drinking straws
Researchers developed a microplastic-free drinking straw by coating bacterial cellulose with ethyl cellulose, achieving strong mechanical performance (66.82 MPa bending strength), water-repellent surfaces, and complete soil biodegradation within 20 days — outperforming conventional polylactic acid straws on both durability and environmental decomposition.
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. The straw achieved strong hydrophobicity, worked well in cold beverages including tea, coffee, and milk, and fully degraded in soil within 50 days. The study offers a promising green alternative that avoids both the microplastic pollution from plastic straws and the chemical additives used in conventional paper straws.

Researchers developed edible straws made from bacterial cellulose and starch using a biomanufacturing approach, as an alternative to plastic straws that contribute to microplastic pollution. The straws demonstrated strong mechanical performance, maintaining their structure in both hot and cold beverages for extended periods. The study suggests that bio-manufactured food-contact materials could help reduce reliance on conventional plastics and the associated microplastic risks.
