Introduction to Life Cycle Analysis (LCA)

Farm Energy March 30, 2012|Print

How much energy does it take to produce biodiesel, compared to the energy in the fuel itself? And what is the total environmental impact of biodiesel production? These questions can be answered using a technique called "life cycle analysis."

Life cycle analysis (LCA) is a relatively recent tool, growing in popularity, that is used to estimate the environmental, energy, and economic performance of a product or a system. In essence, it is a budgeting process that accounts for all inputs (raw materials and energy) and outputs (products, waste materials, and environmental impacting components such as CO2).
