Police are investigating whether a man whose remains were found at a recycling depot fell asleep in one of the bins.
The body of Matthew Symonds, 34, was found on Friday morning at the Biffa operated site next to Avonmouth docks near Bristol.
Detectives believe he had been transported 45 miles in a recycling bin from his home town of Swindon.
His death is being treated as unexplained and officers are waiting for the results of a post-mortem examination.
Senior investigating officer DCI Gareth Bevan said: "Police enquiries so far suggest the body was transported with commercial recycling waste collected in Swindon and therefore the focus of the investigation will be in that area going forward.
"The investigation is at an early stage and we are keeping an open mind about the circumstances leading to his death. Our thoughts are with his family and friends at this very difficult time."
A police team has been working at the waste plant examining machinery and the area where he was found.
Mr Symonds' relatives are being supported by family liaison officers from Wiltshire Police.
