Based in Downers Grove, IL, Sara Lee Corporation is a global manufacturer and marketer of high-quality food, beverage, household, and body care products for consumers throughout the world. Many of its product lines have become household names, including such brands as Ball Park, Endust, Hillshire Farm, Jimmy Dean, Kiwi, and Sara Lee, among others. Collectively, these brands generate more than $13 billion in annual net sales across 200 countries.

Since its inception, Sara Lee has prided itself on conducting its business with integrity. In recent years, this commitment has extended to a comprehensive, global program focused on sustainability. In this exclusive interview, Glenn Ventrell, director of packaging innovation and development for Sara Lee, shares with Packaging World how Sara Lee is confronting the complexities of sustainability throughout its business and throughout the world. Serving in his position for more than two years, Ventrell is a member of Sara Lee’s Global Sustainability Team and is responsible for overseeing the development of food packaging for all of the company’s North American business.

PW: How does Sara Lee define sustainability?
Ventrell: We are a food and household products company. So our definition of sustainability revolves around promoting wellness and nutrition, supporting our communities, and protecting our planet in a manner that is consistent with our values. We have basically three legs that we look at: wellness and nutrition, environmental responsibility [see sidebar, page 36], and social responsibility.

PW: Does Sara Lee have any specific, quantifiable goals related to sustainability?
Ventrell: We are just in the process of finalizing those now. Our year runs from July 1 through June 30, so our next goals will go into place in July. We will have goals for package reduction, for water usage, and for energy that will be part of each Sara Lee employee’s goals for 2010. These goals are not only corporate goals, but they are also goals for each person in the business area affected. For example, the goals surrounding packaging will be part of my goals, my team’s goals, the chairman’s goals, the brand’s goals, and the supply chain’s goals. So we will all be working toward the same set of numbers throughout the company.

PW: When you are looking at designing a new package or redesigning an existing package for greater sustainability, what are some of the most important considerations?
Ventrell: We use the five Rs—reduce, reuse, recycle, renew, and remove—as the premise of all design. Also we are members of the Sustainable Packaging Coalition (www.sustainablepackaging.org), so we use their guidelines, as well. We put those two together, and we see where they marry up, and that’s how we design our packages. Of course, there are economic and other concerns that come into play. But first we design the packaging based around those guidelines.

PW: When you evaluate a package with the five Rs in mind, do you start at the beginning and look at each element to see if the package can be, for example, reduced, reused, recycled, etc., in that order?
Ventrell: It depends whether it is an existing package, because then we may know the answers to some of the five Rs already. If it already exists, and we know that there is no renewable material available for that application, then that would come off the plate pretty quickly. We would probably look at remove and reduce first. And then, if the package is not recyclable today, if we can get it to be recyclable, that would really be a big change.

If we are designing something new, where we have more of a blank sheet of paper to some extent, then we would look at more of the recycle, reuse, renew materials strategy, because we wouldn’t really be removing or reducing at that point.

PW: What role do you see alternative materials such as biopolymers playing in your sustainability efforts?
Ventrell: We definitely see a bigger role as these materials continue to evolve. That may include some of the sugar- or tapioca-based starches that are coming onto the scene more and more, with production plants being built predominantly outside the U.S. We will also likely consider these materials when they have been tested to the same quality levels as the materials that they are replacing. And, we also have to look at the economics. But certainly, if those things start coming into line, which they will over time, then we will be testing those materials.

PW: Can you share an example of a package that was developed or redesigned to be more sustainable?
Ventrell: Sure. One example is the Hillshire Farms lunchmeat in a tub. Last October, we reduced the height of the tub by 3⁄16 of an inch. It doesn’t sound like much. When we first talked about it, most people said, “What does 3⁄16 of an inch really mean?” It means quite a bit when you think about it differently.

The reason we reduced the height of the tub by 3⁄16 of an inch was because we were trying to figure out how to make that package more sustainable after talking with some of our customers. We backed into that number by asking ourselves, “How can we get more packages onto a truck?” What that did for us was it added one more layer per pallet, and the pallets are double-stacked. So that’s equivalent to something like 60 more layers per truck, which took about 900 trucks off the road a year. It also took out of the system about 6,500 pallets, and it reduced the amount of plastic used by about 625,000 pounds, the amount of fuel used by more than 79,000 pounds, and the amount of corrugated by more than 630,000 pounds.

I would say that is one of the things that has changed about designing for sustainability. People were always looking at the front end of design, at the primary selling unit. When you start looking at it from both ends, sometimes you come up with some pretty big sustainability savings. You need to look at it from the truck going backwards, as opposed to looking at it from the container going forwards.

PW: Can you explain how Sara Lee has been redesigning the pallet configuration of more than 1,200 of its items to allow operations to better utilize the space available on trucks and in warehouses?
Ventrell: Up until a couple of years ago, Sara Lee was a group of companies that worked somewhat independently of one other, and so did their factories. As you can imagine, there were all different height and pallet-pattern designs based on local conditions, such as their palletizers, the height of a factory door, whatever. When we went to a central distribution system, what we noticed is that we were either constantly re-palletizing or not being very efficient with trucking.

So we launched a program called Standard Unit Load and, based on standard height and weight guidelines, we were able to maximize the amount of product per trailer, both at the factory level, and, more important, at the distribution center before product was sent to our customers. It really changed the way we did things and the way we shipped to our customers.

To put the program in place, we had to touch almost all of our items to change the pallet patterns. In some cases, we were then able to reduce the corrugated; in other cases, we had to strengthen corrugated. But the end result is that we were able to reduce the amount of trucks on the road by putting more uniform loads on each truck.

PW: Do you have a specific example of a package or pallet pattern that was redesigned for this project?
Ventrell: A good example is our Jimmy Dean breakfast sandwiches. In that case, they were building pallets of product to height. So there was a lot of space above the pallet in the truck, because when you only build one-pallet high, if you build it too high, it’s going to fall over. So, by putting two pallets in the truck, one on top of the other, we were able to extend the height inside the trailer and make more use of the space.

By going to this format, we were able to increase the weight we put on each truck by about 14%. This eliminated 800 truckload shipments, resulting in a reduction of about 532,000 food miles and around 2.3 million pounds of CO2.

The logic in the past would have been, “The more I can get on one pallet to put on the truck, the more money I will save.” The reality is that how much you can cube-out a truck is much more important from a cost and sustainability standpoint.
