Tubby, a Labrador from Torfaen, UK died here yesterday.
The dog, won the title of 'world's greenest dog' by Guinness Book of Records in 2011 after picking up 26,000 plastic bottles on his twice daily walks and crushing them in his mouth.
He would carry them over to his owner Sandra Gilmore, to be recycled, BBC reported.
"It was a pleasure to have Tubby feature in the book. It was a unique record and we are honoured to have been able to verify his achievement in the community," a spokesman of Guinness World Records said.
"He meant so much to us and the local community and he had friends all over the world. He didn't let it all go to his head though as he was always the keenest, greenest recycling canine around with the smallest carbon paw print ever," Gilmore added.
"He was a remarkable dog and did a great job sniffing out rubbish to recycle, and helping to improve the environment for everyone in Torfaen," Torfaen council's waste and recycling manager Cynon Edwards said.
