This study presents a novel thermal technology (high-frequency heating, HFH) for the decontamination of soil containing per- and polyfluoroalkyl substances (PFAS) and aqueous film-forming foams (AFFFs). Ultra-fast degradation of short-chain PFAS, long-chain homologs, precursors, legacy PFAS, emerging PFAS was achieved in a matter of minutes. The concentrations of PFAS and the soil type had a negligible impact on degradation efficiency, possibly due to the ultra-fast degradation rate overwhelming potential differences.

Gathering and injecting CO into shale reservoirs is an effective way to reduce the CO amount in the air and thus, release the greenhouse effect. CO injection into organic-rich shales could provide dual benefits of incremental oil or gas recovery and secure CO storage.
