Demolition began Monday at a corn mill plant that exploded, killing five employees.
The Didion Milling company says demolition could take at least a week as crews have to take the building down piece by piece.
Once demolition is complete, the company's president says they will first focus on resuming ethanol production and then they will rebuild.
"It's best for everyone involved if that just comes down and you start clean," said Riley Didion, the president of the company.
The explosion took place May 31 but the cause is still being investigated. OSHA and the Chemical Safety Board are on-site compiling interviews and reviewing data. They have six months to complete the investigation.
Five employees died and several others were injured.
Those killed were Carlos Nunez, Angel Reyes, Robert Goodenow, Pawel Tordoff and Duelle Block.
All of the injured employees were released from the hospital.
The rest of the employees are back to work, either on clean-up efforts or at other Didion locations in the state.
Crisis counselors have been meeting with employees since the incident.
"What happened happened and now is kind of a new slate," said Didion. "The canvas is clean for us to recreate that facility and to come back in a different way."
