Lowering Greenhouse Gas Emissions
Heinz surpassed our 20% reduction target in greenhouse gas (GHG) emissions two years before the target of April 2015. As a global food company, Heinz recognizes that climate change is a significant environmental concern and that reducing GHG emissions can help protect the planet. During the reporting cycle, we continued to evaluate innovative and sensible opportunities at our factories and within our Supply Chain to contribute to further reductions.
Through our Global Utility Optimization Program, Heinz assesses facilities in each of our business units and identifies potential energy-saving projects. In 2012 and 2013, Heinz employees continued to execute utility-focused factory assessments (Kaizen Events) at many of our facilities globally. The objective of these employee-led events was to identify and initiate opportunities to improve energy efficiency, which in turn can directly and indirectly help reduce GHG emissions. These assessments resulted in the following projects to drive improved energy utilization in our manufacturing facilities:
- Boiler/steam optimization
- Compressed air optimization
- Process heat recovery
- Water reclamation
- Waste recycling optimization
An added benefit of these projects included a projected 2% to 4% reduction in energy/utility consumption per year per factory.
Global Utility Optimization Program
Global Utility Optimization (GUOP) is an integral process Heinz follows to save on energy, utilities, and costs both for the present and the future. In large plants, such as Muscatine Iowa and Fremont Ohio, our staff of engineers and environmental professions conduct assessments to determine where additional utility savings can be generated. In most cases, Heinz identifies several projects at each location which range from reusing hot and cold water, heated make up air, compressed air, steam condensate, essentially any form of energy. Once viable projects are identified estimated savings, project costs, and the simple payback are calculated. This information helps prioritize which projects to implement first. An example of a project in Muscatine, Iowa includes revising how the water in the hot well reclaim tank is utilized. Currently, there is some mixing of warm water with the hot water which negates the effectiveness of the energy reclaim. Our analysis indicates that by spending an estimated $50,000 an estimated savings of $62,000 would be realized over 9.6 months. This is just one example of several projects that are leveraged to save energy and optimize utility usage.
