Hydrothermal production of algal biochar for environmental and fertilizer applications: a review

Climate change and pollution induced by fossil fuel consumption is calling for alternative, renewable organic products in the context of the future circular economy. For instance, biochar has emerged as a versatile material produced during pyrolysis, hydrothermal liquefaction and gasification of bio...

Zusammenfassung:	Climate change and pollution induced by fossil fuel consumption is calling for alternative, renewable organic products in the context of the future circular economy. For instance, biochar has emerged as a versatile material produced during pyrolysis, hydrothermal liquefaction and gasification of biomass such as algae, plant and organic waste. Here, we review algal biomass, biochar production by hydrothermal liquefaction, biochar properties and biochar fertilizer value for plant growth.
