Environmental Sustainability
Unlike fossil carbon sources, soybeans capture carbon dioxide from the atmosphere. They also fix their own nitrogen for plant food, which provides an initial life-cycle advantage over other oilseeds that require nitrogen fertilizer made from natural gas. Most soybean acreage in the U.S. uses conservation tillage, which disturbs less soil and reduces fuel use.
A Life Cycle Assessment Study shows environmental benefits of manufacturing products using soy feedstock, including:
- Lower carbon dioxide emissions
- Reduced energy costs
- Lower VOCs of some products
- Reduced exposure to toxic chemicals by workers
- Supply chain sustainability
- Credits toward LEED certification of some finished products
- Reduced processing costs and environmental compliance fees
