I don’t applaud this as an uplifting environmental story, but maybe an entrepreneurial one. *Many existing brooms are made of plastic anyway so it’s not more detrimental than a current solution.
Either way it smells of a “don’t worry about plastic pollution, this dude will turn it into brooms :)” type jig.
*Edited to clarify many brooms are plastic, before someone jumps on and starts throwing straw brooms at me :)
