He said he works in the building himself and that it isn't unsafe for workers.
"I'm not going to do anything to put myself, or my employees, in danger," he said.
The roof is the only major structural issue but it isn't ready to cave in, he said. The state of the roof is more of an inconvenience than anything, he said.
"There are holes in the roof, so water leaks into the building, but that's it," he said.
Watkins agreed, saying Hunyadi is not operating heavy equipment inside. Watkins was told by the Charleston building commissioner and fire chief that the building was structurally sound except for the roof.
He added that the combustible dust would only become an issue when Hunyadi begins to process office paper, which he currently isn't doing.
"He'll have to address the ventilation in that building before long, but I'm confident he'll do that," Watkins said.
Sayre pointed to an engineering report from last year that showed the building was unsafe.
Russell also said she believes Hunyadi will provide a safe work environment for his employees.
Russell and Watkins both said they were surprised by Sayre's abrupt resignation. Sumemrs said she saw it coming.
"I knew he was unhappy with the direction we were taking," she said. "He was opposed to this from the start."
Hunyadi believes Sayre was opposed to him taking over the center from the beginning, pointing out that one of his clients, West Virginia Cashin Recyclables, filed a lawsuit against him the day after he signed the lease with the authority.
The company sued West Virginia Recycling Services based on name infringement.
The lawsuit is still pending before Kanawha County Circuit Court Judge Carrie Webster.
Hunyadi does not believe the name of his company will become an issue.
"The Secretary of State reviewed the name when I filed with the office and said it was OK," he said.
The state Department of Environmental Protection appointed Sayre to the board for a four-year term in 2009. His term was slated to end on in June, DEP spokeswoman Kathy Cosco said.
The state agency is asking any person interested in serving on the Kanawha County Solid Waste Authority to contact the office at 304-926-0440. The agency will likely appoint someone to the seat at the beginning of July, she said.
Cosco also said the DEP had no prior knowledge of Sayre's impending resignation.
