Title: Tandem biochemical and thermochemical conversion of algal biomass

Abstract

The present invention relates to methods and system configured to convert algal biomass into biofuels, alcohols, nutrients, biochar, chemical building block compounds, and/or other useful by-products. Exemplary methods include an integrated biochemical and thermochemical process that provides high purity biofuels and mixed alcohols, while minimizing waste and/or maximizing efficiency.
