Fulfilling LCA’s Promise
LCA XIII International Conference edition:13 location:Orlando, Florida, United States date:1-3 October 2013
LCA is widely applied to compare multiple scenarios of supply chains in all the variety of operations needed for handling and transporting biomass. Due to the large number of product and operation types, supply chain planning requires choosing the best alternative combination of products and operation types in a decision environment with specific, pre-defined objectives.
To ensure a comprehensive evaluation of the biomass-for-bioenergy supply chain, all operations from crop harvest to delivery in conversion facilities are identified in a cradle-to-gate life cycle inventory. Each operation is characterized by attributes related to energy use, economic cost and GHG emissions. Then, the mixed integer linear programming model is applied to define the strategic design with the maximal cumulative energy output, the maximal cumulative profit or the minimal cumulative GHG emissions determined through life cycle impact assessment. The
approach is applied to a supply chain of low input high diversity biomass in Belgium.
