Soil contamination by mixture of compounds represents a challenging environmental problem to face,
especially for the risk connected to the human health, due to the possible diffusion of the pollution in
the groundwater. One of the most used remediation technology is adsorbtion on carbonaceus material
and Activated Carbon (AC) is the most used one, even if it is usually connected to high costs. Biochar (BC)
is proposed as an alternative low-cost material for the removal of wide range of contaminants in the

A sequential reductive-oxidative treatment was developed in this study in a continuous-flow bioelectrochemical reactor to address bioremediation of groundwater contaminated by trichloroethene (TCE) and less-chlorinated but still harmful intermediates, such as vinyl chloride. In order to optimize the anodic compartment, whereby the oxygen-driven microbial oxidation of TCE-daughter products occurs, abiotic batch experiments were performed with various anode materials poised at +1.20 V vs.
