Castletown commissioners say they've asked a local business to clear up after itself.
The company, which hasn't been named, had dumped commercial waste in litter bins.
The local authority says it offers a waste collection service for commercial customers but business rubbish shouldn't be put into bins.
On Facebook, the board posted a photo of the waste, saying it was returned to the company for disposal.
