Simplot's Moses Lake potato processing plant received Environmental Excellence award

Several green initiatives in place at J.R. Simplot's Moses Lake facility were highlighted during a recent Association of Washington Business meeting. 

The potato processing plant received an AWB Environmental Excellence award in Spokane earlier this week. Simplot was one of seven Washington businesses to win an award this year. 

According to AWB president Don Brunell, Environmental Excellence awards are given to businesses that implement progressive and environmentally sensitive practices. 

"These award winners are meeting the needs of their customers and taking care of their communities while showing that environmental sustainability is a smart way to do business,"he said. Simplot's use of its anaerobic digester was one reason the company received the award. The digester, nicknamed Bertha, allows the company to recycle wastewater from their potato processing into high nutrient irrigation water. 

The digester began operating in 2007, according to a previous Columbia Basin Herald article. It holds up to 20 million gallons of process water. 

A storage pond also holds about 220 million gallons of processed water during non-irrigation periods. The water is recycled by irrigating about 9,600 acres of crops, including sweet corn, potatoes, wheat and alfalfa. 

The irrigation water saves growers about $800,000 a year, according to the AWB. The digester also produces up to half a million cubic feet of biogas a day. The biogas is pumped back to the plant to produce steam necessary for French fry production, according to the article. 

Plant manufacturing manager Mark Knight said the work of employees at the facility helped them win the award, not just the state-of-the-art equipment.
