That was the message Oct. 15 at “By the Numbers: The ROI of Sustainability,” a workshop at the Produce Marketing Association’s Fresh Summit 2011.

“All over the world, companies are talking about sustainability — consumers are talking about sustainability,” said session moderator Mary Shelman, director of the agribusiness program at the Boston-based Harvard Business school.

Nikki Rodoni, director of sustainability for Oxnard, Calif.-based Gills Onions LLC, talked about the process Gills developed to convert waste from its fresh peeled onion product into a source of renewable energy and cattle feed (which the company sells). Gills produces about 300,000 pounds of onion waste a day, Rodoni said, and previously ejected it onto fields to dispose of it.

“We spent $450,000 a year on fuel and labor just for that,” Rodoni said.

She said it was sometimes difficult to get support or approval for the energy system from financial backers and government regulators, but that Gills’ owners saw the program as necessary for the company’s continued growth.

The system, which began operating in 2009, has allowed Gills Onions to virtually elminate the waste stream from its onion processing, Rodoni said, and saves about $700,000 a year on energy costs.

Ad Klaassen, secretary general of the Dutch Produce Association, Breda, The Netherlands, talked about a partnership formed in 2009 between the government and private sector companies to use glasshouse growing as a source of energy. He said there are currently 5,000 hectares (12,355 acres) of glasshouse fruit and vegetable production in Holland, and the project’s goal is to make glasshouses energy neutral by 2020.

He said the program is exploring multiple ways to limit overall energy use, use renewable energy and make fossil fuel use more efficient. Those include optimizing the temperature, humidity and CO2 levels in glasshouses, better use of natural and LED lighting, geothermal energy and research into bio energy techniques.

Hugh Mowat, technical manager of fresh produce and flowers for London-based Marks and Spencer PLC, gave an overview of Marks & Spencer’s effort to make the firm the world’s most sustainable retailer.

“It was called Plan A because there was no Plan B,” Mowart explained.

As a consumer I'm not so much interested in sustainability as more in having safe food for my family and if something is happened it's taken off the market immediately. All those sustainability talk is watering down the real problems. What is sustainability in the produce industry and how do you prove it anyway? Farming is a sustainable system as it is for generations. If this wouldn’t be true there wouldn’t be farming!
