In a recent article published in Advanced Sustainable Systems, researchers developed an all-natural alternative to plastic straws using a top-down molecular welding approach. This straw is made from de-lignified natural wood infused with chitosan, resulting in a flexible, moldable material that can be shaped as needed.​​​​​​​ Plastic straws are widely used consumer products, prompting significant efforts to develop biodegradable alternatives to replace petroleum-based plastics. However, existing options like polylactic acid and paper straws come with notable drawbacks, making them less-than-ideal substitutes. To effectively replace plastic straws, there is an urgent need for biodegradable, environmentally friendly materials that offer both mechanical durability and water resistance. …Overall, the researchers successfully prepared microplastic-free, ultra-strong, hydro-stable, and biodegradable all-natural bendable straws through a top-down method using earth-abundant natural wood and edible chitosan.
