ClearAll-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.
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.
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.
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.
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.
An Innovative Alternative to Plastic Straws with Bacterial Cellulose
This study developed biodegradable bacterial cellulose as an alternative material for drinking straws, replacing conventional plastic. Bacterial cellulose straws are fully biodegradable, offering a practical solution to reduce the single-use plastic that fragments into microplastics in the environment.
Edible Straws as Promising Biodegradable Alternatives to Single-Use Plastics: A Comprehensive Review
Single-use plastic straws are a small but symbolic part of the microplastics problem, and this review surveys research into edible straws as a biodegradable alternative, covering materials ranging from cassava starch and seaweed to cellulose and proteins. Lab results are promising — cellulose-based versions show good strength, seaweed-based ones biodegrade quickly, and life cycle analyses confirm ecological advantages over plastic — but challenges including high production costs, short shelf life, and lack of regulatory standards are holding back commercial adoption. The review concludes that realizing the potential of edible straws will require coordination across material science, food engineering, and policy.
Microplastic and adhesive free, multifunctional, circular economy approach-based biomass-derived drinking straws
Researchers developed drinking straws made from rice straw waste that are free of microplastics and adhesives. The study suggests these bio-based straws are water-stable, heat-resistant, antibacterial, and biodegradable, with a dramatically lower carbon footprint than metal or polylactic acid alternatives, turning agricultural waste into a useful consumer product.
Growing Strong Polysaccharide-Derived Edible Straws with an Inherent Structural Binder via Biomanufacturing
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.
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.
Bio-based alternatives to plastic drinking straws: are they more environmentally benign and consumer preferred?
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.

Researchers developed edible drinking straws from Guso seaweed (Eucheuma cottonii) with different plasticizer concentrations and evaluated their biodegradability, strength, and water resistance.

Researchers developed a new type of drinking straw made from bacterial cellulose that is edible, free of microplastics, and mechanically stronger than paper straws. The straw uses an alginate coating instead of adhesives and has a three-dimensional nanofiber structure that outperforms commercially available alternatives. This biosynthesized straw offers a healthier and more environmentally friendly replacement for disposable plastic straws.

Steam Transmission of Bioplastic Straw based Carrageenan and Gelatin
This study developed bioplastic straws made from carrageenan (seaweed extract) and gelatin as an alternative to conventional plastic straws. The researchers found an optimal gelatin concentration that gave the best water resistance and shelf life. This matters because regular plastic straws are a major source of microplastic pollution in oceans and waterways, and biodegradable alternatives could help reduce that contamination.
