Subcritical water hydrolysis (SWH) | Subcritical water hydrolysis (SWH), also called h''ydrothermal liquefaction'', ''hydrothermolysis'', or ''aquathe''rmolysis, has potential for breaking down the cellulose and hemicellulose biopolymers into simple sugars and small molecules. The technique uses water at high temperatures and pressures to keep it in a liquid form. SWH can reduce reaction time and thereby degradation product formation, generates less waste water and lower corrosion requirements.<ref>{{Cite journal|title=Subcritical water hydrolysis of sugarcane bagasse: An approach on solid residues characterization|year=2016-02-01|author=D.
