Less use of water also plays into energy reduction. "We do more dry clean-up – simply picking pieces off the ground. Before that, some employees would stand with a hose all day and flush debris down the floor drains," says McLeod. That reduces both electrical and natural gas needed to heat and pump the water.
Water also is saved by proper use of nozzles and pressure, and making sure hoses are completely turned off after use. "It really was a people education thing," says McLeod. Managers also found they could reduce some sanitation cycles. Altogether, water use was reduced by 3 million gallons in 2017 alone (over 2016), "and it's going down every year," McLeod adds. "When you save 3 million gallons of water a year, you're also saving energy."
But perhaps the Orange City plant's biggest environmental accomplishment has been in waste reduction. "In 2016 we began working toward zero landfill status," says McLeod. "We were sending more than a million pounds a year to landfill."
It didn't involve a big capital outlay and it took two years to work out – there was a lot of coordination with recyclers and education of employees. But plant officials found recyclers for all the corrugated, plastic, metals and paper. "We found a home for everything," says McLeod.
"One of our biggest waste streams is wastewater residuals," says Meyer. "We run all our wastewater through dissolved air flotation units, but the solids, the grease, we skim away and it gets land-applied in the spring and fall. The farmers love it. That's a big amount of waste material that goes to a beneficial reuse."
Corrugated totes and their plastic liners formerly were reusable somewhat, but eventually wore out and became waste. They were replaced with plastic totes that are reusable and easy to clean.
For the 10th year, we asked readers to help us honor the best recent examples of green or sustainable processing plants. Back in July, we whittled down a handful of nominations to three: Chobani's Twin Falls, Idaho, yogurt-making plant; ISO Group's Riverside, Calif., facility; and Smithfield Foods' Orange City, Iowa, pet food plant.
We asked each facility for 200-word essays to help familiarize readers with their efforts. Then we put all three essays and a poll on our web site, and nearly 500 readers picked the winner: Smithfield Foods. That plant joins our previous winners, which you can find in our Green Plant of the Year Award section.
In nominations and the final vote, we listed several points we were looking for in a Green Plant of the Year:
- Is it energy efficient?
- Does it use innovative or alternative sources of energy?
- It is minimally polluting?
- Does it minimize water use?
- Were green building materials and practices used in its construction?
- Is the design innovative?
- Is it economically sustainable?
"Any material we can't find a recyclable home for goes to a private company in Manketo, Minn., that burns the material to generate electricity.
"A lot of people, companies in the local community, are asking them how they did it, wanting to emulate what they did," says Meyer. "The plant has become a shining star for sustainability in the Orange City area."
In addition to the environmental benefits, "we even receive money back for some of the recyclables," notes McLeod.
In 2013, the plant qualified for ISO 14001, an international quality standard for effective Environmental Management Systems (EMS). The standard provides a framework an organization can use to enhance its environmental performance, managing its environmental responsibilities in a systematic manner that contributes to the environmental pillar of sustainability. An effective EMS should provide value for the environment, the organization itself and other interested parties.
Last year, the Orange City plant was among 43 Smithfield facilities recognized by North American Meat Institute (NAMI) for environmental achievements (as well as 24 company locations NAMI cited for workplace safety accomplishments). The NAMI Environmental Awards program recognizes companies that go beyond compliance by developing and implementing innovative environmental programs. It is a four-tiered program beginning with simple environmental compliance policies in Tier 1 and culminating with the more complex ISO 14001 Environmental Management Systems (EMS) as Tier 4.
The facility’s sustainability efforts extend into the local community with the ongoing support of the National Conservation Foundation Envirothon program, which engages students in environmental problem-solving.
"There is another benefit: employee pride," adds Meyer. "Leadership takes great pride in these efforts and so does every employee. It makes them proud of everything they do. It comes down to culture and leadership, and Paul and his team have ingrained this mindset in all their employees. It helps with morale and it helps with retention. When employees have pride in their job, they do a better job."
