Signing an executive order on Monday to reverse federal purchasing policies which encourage paper straws and restrict plastic ones, Mr Trump said: "It’s a ridiculous situation.
The order directs federal agencies to stop buying paper straws "and otherwise ensure that paper straws are no longer provided within agency buildings.".
However, by contrast Mr Biden, 82, wanted to phase out federal purchases of single-use plastics, including straws, from food service operations, events and packaging by 2027, and from all federal operations by 2035.
More than 390 million straws are used every day in the United States, mostly for 30 minutes or less, according to advocacy group Straws Turtle Island Restoration Network.
Speaking at the White House on Monday, Mr Trump said he thinks "it's OK" to continue using plastic straws.
