Hydrothermal liquefaction (HTL) represents a versatile and promising thermochemical process that
exhibits the capacity to effectively convert wet biomass and organic waste into a valuable liquid
bio-oil. The hydrothermal liquefaction process operates on the principles of high temperature,
high pressure, and the presence of water. Biomass or organic waste feedstock, typically with a
high moisture content, is subjected to temperatures ranging from 250 to 400 degrees Celsius
and pressures between 10 and 25 megapascals (MPa). At these conditions, the complex organic
compounds within the feedstock undergo thermal decomposition and chemical reactions, leading
to the formation of a liquid bio-oil. This technology holds immense potential across various
domains, including biofuel production, chemical feedstocks, waste recycling, and resource
efficiency. Consequently, HTL plays a pivotal role in sustainable waste management and the
advancement of an environmentally conscious and resource-aware society. The applications of
HTL encompass a wide array of fields, encompassing biofuel production, chemical raw materials,
waste evaluation, resource efficiency, and sustainability. Notably, during HTL experimentation,
residual wastewater following the extraction process contains numerous chemical compounds that
cannot be effectively recovered through conventional chemical methodologies. The accumulation
of these chemical compounds poses environmental challenges, necessitating mitigation strategies.
One viable solution involves the utilization of this waste process water in agricultural applications,
including fungi control and algae cultivation. This approach serves the dual purpose of preventing the release of harmful chemicals into the environment while concurrently generating economic
benefits.
