Use of Roadside-green-cuttings for Anaerobic Digestion as a Potential Phytoremediator to Hinder Biogas Production Inhibition Through High Lead (Pb) Concentrations

The utilization of roadside-green-cuttings (grass) for anaerobic digestion increases the possibilities of using organic wastes as a renewable energy source. Grass can be used as a substrate to increase biogas yield. Nevertheless, the anaerobic digestion of this kind of wastes can be limited due to the fact that they could be contaminated with heavy metals, caused especially from traffic emissions and industrial activity. For this reason the biogas production of grass from a busy road...
