Food Processors Baking Profits into Energy Savings

P&L meets environmental sustainability in the baking business as Energy Star and associations put energy savings at the forefront.

Ready to put his Purdue University degree to work, Dave Van Laar, dug into one of his first assignments as an industrial engineer: to cost-justify the purchase of a cardboard bailer. "When I did the initial justification, we were going to make $10,000 a year selling the cardboard scrap. But by the time we got it purchased and installed, the board market had changed so much we had to pay someone to haul it off."

That was the 1970s. Since then the board market has changed. A lot. Also since then, Van Laar's career took off with operations and management positions leading him to baking companies including Pepperidge Farm and ultimately, Oak State Products, a Wenona, Ill.-based contract baker of cookies and bars. As president and CEO at Oak State, he again presides over a compacting-and-baling operation that is decidedly more profitable than using open-top containers and loose hauling of waste. One truck does the work of seven, eliminating an annual 213 truckloads and 6,390 gallons of diesel a year to save him $44,730.

"We're saving fuel, we're saving transportation costs, and we're also eliminating trips to the landfill," he says, adding that one of the company's goals is "zero landfill" by 2013. To help him reach that goal, the company also is bumping up recycling and vendor packaging reductions.

Another company shares the same zero-landfill dream: that granddaddy of the supply chain, Walmart. Picking through its waste stream, literally and figuratively, to donate usable goods and streamline its suppliers' packaging materials, the company reduced its landfill load more than 80 percent; a national rollout is now planned.

"You go through your P&L," Bill Simon, president and CEO of Walmart U.S., said at the company's Global Sustainability Milestone Meeting in March, "and you see this big line that's called 'waste removal' and it's a negative charge." Through commitment analysis and teamwork, "that line, that was a big negative on our P&L, is now turning into actually a fairly large positive."

Anyone doing business with Walmart or any company with global brand recognition knows that environmental sustainability isn't just a marketing ploy. It's a prerequisite for doing business -- as well as a mandate, and opportunity, to make wise capital investments. The environmental aspect of sustainability, alongside financial and corporate responsibility initiatives, is prominent on Wall Street and tracked in the Dow Jones, Ethibel and other sustainability indexes.

Another index, Walmart's Sustainability Index (, hits lesser-known companies who rank among the mega-retailers’ 100,000-plus suppliers now subject to sustainability assessments, measurements and improvements. Walmart requires suppliers not only reduce their own carbon footprint, but ensure that their own suppliers are in line with those efforts. This includes ingredient and material suppliers as well as, say, contract bakers.

Oak State's profitable sustainability
Oak State Products had been working on sustainability "for several years because it was the right thing to do," says Van Laar. "As we did that, we found it also became the profitable thing to do."

In addition to its landfill reduction efforts, Oak State has made investments in several areas:

  • Electricity: A switch to high-efficiency fluorescent T5 and T8 lighting saved the company an annual 1 million-plus kilowatt hours for a 45 percent reduction in operating costs and a one-year payback. Motors continue to be replaced as needed with "the highest-efficiency motors we can get," says Van Laar, which is a "no brainer" in light of advances in technology.
  • Natural gas: Usage gauges, burner efficiency tests, meters on individual zones and data loggers as well as tuning individual oven burners "give us a better handle on what we're using per zone," says Van Laar. Tuning burners has improved burner efficiency by 10 percent. Oven exhaust and heat recapture and reuse may be in the cards.
  • Water: Reductions in consumption include a switch from using water for cleaning to dry cleaning and sanitizing as much as possible. A wastewater treatment project is underway targeting biological oxygen demand reduction to less than 200 mg/L.

Oak State's environmental efforts gained steam when one large customer who had requirements to meet, in turn, helped the bakery along the way.

"From there it just took off to looking at everything in the plant," Van Laar says.

Such assistance from larger companies is commonplace, according to Walt Tunnessen, national program manager for the U.S. Environmental Protection Agency's Energy Star program for Industry. He says large companies in the program have been "very active" in mentoring others in their journey into compliance and sustainability.

Oak State's sustainability efforts earned the company an Energy Star certificate in 2010 that has proved to be a "huge boost," says Van Laar, noting that customers familiar with the company "don't even ask us about sustainability anymore. They know we 'get it,' that we know what we're doing and we get it done," he continues.

The marketing value of brandishing an Energy Star logo is just an echo of the operational and financial benefits gained, because being "green" in public is a result, not the cause, of significant operational efficiency improvements. Oak State's example is as inspiring as -- perhaps more so than -- the efforts of industry giants, because the single-plant company shows that you don't have to be PepsiCo to be – to borrow a term – an Energy Star.

Energy Star provides the tools
Under Energy Star's industry partnership program, companies that reduce energy consumption 10 percent over five years or less can become an Energy Star Partner and earn certification and rights to promote the Energy Star logo in company materials.
