Increasing the overall carbon and energy efficiency by integration of thermal processes with biological ones has gained considerable attention lately, especially within biorefining. A technology that is capable of processing wet feedstock with good energy efficiency is advantageous. Such a technolog...

By hydrothermal liquefaction (HTL) of organic matter, hydrochars are produced which may be applied to soil for carbon sequestration. From substrates of wild seaweed and organic waste digestate, we measured the distribution of solids (hydrochars) and liquids after HTL at 150 and 200°C, 50 bar fo...
