Life cycle assessment (LCA) is a tool used to assess the full environmental impact of a product’s life. This includes the impact due to raw materials production, materials processing, manufacturing, customer end use, and the final disposal of a given product. An LCA is required for approved pathways of the California Low Carbon Fuel Standard (LCFS) as well as the US EPA Renewable Fuel Standard (RFS). In addition, the energy and mass balances performed during an LCA are the starting point for process flow analysis, which provides vital information for process improvements energy and cost efficiency. MicroBio Engineering has extensive experience in the analysis of biofuels, algal animal feeds, and wastewater treatment. We offer full life cycle analysis of your product which includes:

  • Definition of System Boundaries and functional units

  • Life Cycle Inventory

  • Energy Balance

  • Mass Balance

  • Impact Assessment

  • Interpretation of Results

MicroBio Engineering uses its proprietary Environmental Sustainability and Process Economics (ESPE) model to assess biofuel and wastewater treatment processes in addition to openLCA software with the ecoinvent life cycle inventory database.
