“…[11][12] As for plantbased straws like paper straws, although they are the most commonly used alternatives to plastic straws, their mechanical properties are still relatively limited. They also need the binder and additional hydrophobic coating to compensate for the poor water-resistant ability, [13][14] which increases the cost. Nevertheless, paper straws still soften quickly and collapse easily in drinks, leading to an unpleasant user experience.…”

The widespread use of disposable plastic straws cause serious environmental problems and poses potential threats to human health, while paper straws, their most used alternatives, are not so satisfactory due to poor mechanical performance and unpleasant user experience. Here, a new kind of edible and microplastic-free straw made from bacterial cellulose (BC) by biosynthesis is reported. Through the alginate coating, this BC-based straw achieves better mechanical performance than paper straws and avoids additional adhesives. Owing to the 3D nanofiber network and strong interlayer connection, the comprehensive performance of this BC-based straw surpasses that of commercially available counterparts, satisfying the requirements for practical use. Of particular note, the edible character provides a better user experience and a new end-of-life option for the straws, making the BC-based straw a healthier and more eco-friendly substitute for plastic straws.

“…1). At the three temperatures(4℃, 20℃, and 90℃) about two-thirds of the extractable PFAS dissolved in water, without statistically significant difference between them [28]. These substances give the paper straws water-resistant properties, and although they have hazardous and bioaccumulative nature and are being phased out voluntarily in the United States, they are still continuously detected [28].…”

“…Paper straws will biodegrade within a few weeks in nature if the straws are made out of pure paper with no traces of any toxic chemicals or plastic lining. Unfortunately, many products advertised as biodegradable, especially paper products, have been confirmed to contain PFAS [28]. Whether it is sent to a landfill or a commercial composting facility, the PFAS in these products is difficult to separate.…”

In recent years, plastic pollution has become one of the environmental issues of concern. This article explores the hazards of plastic straws and analyzes whether the decision to replace plastic straws with paper straws in the context of plastic restriction is entirely environmentally friendly. The results show that plastic films used in agricultural production remain in the soil after weathering and degradation, affecting soil structure, water and nutrient transfer processes, secondary salinization, and hindering plant growth. Microplastics in terrestrial and marine ecosystems are taken up by and accumulate in organisms and enter the human food web, affecting the human central nervous system and reproductive system. This article concludes that paper straws contain harmful additives, are challenging to recycle and degrade, are costly to build, are not environmentally friendly, and have a low promotional rate by studying their life cycle, content, recycling rate, degradation rate, usage problems, and applying. The paper also introduces the advantages of some new green straws, such as bamboo straws, wheat straws, PLA straws, and stainless-steel straws, which are environmentally friendly, durable, biodegradable, recyclable, and reusable. This essay aims to find better alternatives to address the potential environmental problems associated with plastic straws and mitigate the environmental hazards associated with the use of plastic products.
