After harvesting, the biomass is typically dried and incinerated to produce a "bioore" prior to the product recovery process (Chaney et al., 1998, van der Ent et al., 2021, Vaughan et al., 2017). At first, the product recovery process has focused on crude metal extraction from the 'bioore' using pyrometallurgy (Chaney et al., 2007).
