Membrane and Electrochemical Based Technologies for the Decontamination of Exploitable Streams Produced by Thermochemical Processing of Contaminated Biomass

Phytoremediation is an emerging concept for contaminated soil restoration via the use of resilient plants that can absorb contaminants. The harvested biomass be thermochemically converted to energy carriers/chemicals, linking decontamination with biomass-to-energy and aligning circular economy principles. Two thermochemical conversion steps biomass, both used treatment/exploitation, are considered: Supercritical Water Gasification Fast Pyrolysis. For former, vast majority contaminants transferred into liquid gaseous effluents, thus application purification necessary prior further processing. In Pyrolysis, mainly retained in solid phase, but a part appears phase due fine solids entrainment. Contaminants include heavy metals, particulate matter, hydrogen sulfide. purified streams allow in-process re-use water Super Critical Gasification, sulfur-free catalytic fuel-rich stream same process fuels recovery exploitable bio-oil rich from Considering fundamental importance purification/decontamination exploit aforementioned integrated context, review available such technologies conducted, options shortlisted. Technologies choice polymeric-based membrane gas absorption desulfurization, electrooxidation/electrocoagulation product microfiltration ceramic membranes removal Pyrolysis bio-oil. Challenges, risks, suitable strategies implement these context discussed recommendations made.
