However, there is uncertainty regarding the suitability of biomass from bioremediation as a feedstock for production
of biochar as pyrolysis has effects on the speciation and
bioavailability of metals in biochar (Farrell et al., 2013).
In this study a world-first validation of large-scale macroalgal
cultivation and bioremediation is conducted at an Australian coalfired
power station demonstrating a sustainable means of producing
biomass for value-added applications. First, the productivity
of biomass, the bioremediation of AW and biological C capture is
quantified in ponds using a native species of freshwater macroalgae
(genus Oedogonium). Second, biochar is produced from the biomass
and its physico-chemical characteristics, suitability for soil
amelioration, and ability to retain the metals accumulated by
Oedogonium from the AWare assessed.
