Petfood manufacturer WellPet recently unveiled the US$20 million expansion of its dry dog food processing plant in Mishawaka, Indiana, USA, according to a report.

When the petfood plant expansion is complete, the company will add 45 jobs, as well as green technology and automated petfood packaging.

"Where we come from we were three or four people running a packaging line and we're now at a point where we can run a packaging line with one person," said Steve Griswold, director of plant operations.

The total plant expansion project should be completed by September.
