pre-consumer food and organic waste into non-renewable energy.The company released a statement through the Village of St. Bernard's social media, stating that this past weekend, organic material from the wastewater treatment tank foamed over the top of the tank. They said windy conditions and cold temperatures led to the foam coming out of the tank.A spokesperson for the company told us the material is nonhazardous and was contained within the plant site.However, residents nearby are dealing with a stinky consequence."It smells like someone's been in the dumpster for quite some time, but like a million times worse," said Elmwood Place resident Tom Swafford.WATCH: We looked into what happened at the facility and how it's impacting nearby residents Waste facility material foams over, residents describe strong odorWe spoke to Swafford Tuesday about what happened.

We dont need to be dealing with that kind of situation walking out of our door," Swafford said.Swafford said he wants the company to find a fix fast.Hopefully they learn from this, and in two weeks were not talking again, because this is kind of ridiculous at this point," Swafford said.
