As established from our 2011 base year, our target is to reduce greenhouse gas (GHG) emissions by 77,000 metric tons of carbon dioxide equivalent (CO2-e) by 2020. In fiscal 2013, we implemented projects that resulted in a reduction of 17,000 metric tons of GHG emissions from our manufacturing operations, reaching 22 percent of our goal when combined with our 2012 progress. Of the total GHG emissions, direct GHG emissions were approximately 30 percent and indirect GHG emissions were approximately 70 percent. Normalized GHG emissions for manufacturing plants were .31 metric tons CO2-e per ton of production, down 1.5 percent from the prior year level. We are currently on pace to reach our 2020 goal.
Recent projects to reduce air emissions include the following:
Converting farms from LP to natural gas:
Our Jennie-O Turkey Store live production team implemented an initiative to convert several farms from liquid propane (LP) to cleaner burning natural gas. In 2013, 22 farms and one feed mill were converted from LP to natural gas, which included 122 individual buildings, 12,000 heaters, and the installation of approximately 81 miles of underground pipeline. By converting these farms, the team lowered emissions by 979kg CO2-e / 1,000 gallons of LP converted to natural gas. The anticipated emissions reduction from this project will be equivalent to taking more than 675 cars off the road.
Implementing heat recovery technology:
The team at the Fremont (Neb.) Plant identified an opportunity to recover waste heat from the cooking and cooling process of select products. Water and heat recovery equipment were integrated into the recently installed retort cooker addition. This project reduced GHG emissions by 2,300 metric tons CO2-e in 2013.
