The gasification of microalgae in supercritical water was investigated in this work. The product gas contained mainly H2, CO2, CH4, and C2H6. Operation at high temperatures and lower biomass concentrations resulted in the highest carbon gasification efficiency and the lowest total organic carbon levels in the residual water. Due to its content of inorganic nutrients, the residual water was applied as cultivation medium for microalgae. However, algal growth in the untreated residual water was… 
Reutilization of Algal Supercritical Water Gasification Waste for Microalgae Chlorella vulgaris Cultivation
TLDR
Effluents obtained through a supercritical water gasification (SCWG) process at 400 and 600 °C were mixed with Bristol Medium to cultivate Chlorella vulgaris, indicating the possibility of using a combination of C. vulgaris and SCWG for nutrient recycling processes.
New Application of Supercritical Water Gasification to Palm Oil Mill Effluent: Gasification and Phosphorus Recovery
The simultaneous production of fuel gas and inorganic phosphorus from palm oil mill effluent (POME) in supercritical water was experimentally studied herein. A laboratory-scale continuous reactor was
