Additionally, paper straws are often more cost-effective than plastic straws, making them a more economical choice for many businesses.</s>\ <s>[INST] But paper straws do melt and ruin the drink at times. Isn't there a substitute material that is also biodegradable? [/INST] It is correct that there are more suitable materials when concidering how long the straw last in a drink. This could include materials like metal straws, bamboo straws, or even some made of seaweed, a variety of other woods, or even coffee grounds pressed into straws under high pressure.
