Significant efforts are afoot to reduce plastic waste and one way of doing so is to revert to using natural straws as drinking straws.
This example uses wheat straws but it doesn't matter which plant is used, particularly as the word 'straw' is non-specific (see Cambridge) and can relate to any grain producing a hollow stalk.
So if a non-specific straw is used as a drinking straw can we call it a 'straw straw' ?
Or is there a better description ?
Edit Note : The term 'natural straw' would not be specific to usage as a drinking straw. It could be used for other things. The term 'straw straw' makes clearer both composition and use, I believe.
