In the context of a joint research project in collaboration with the municipal water works of Leipzig, BioPlanta optimizes the phytoremediation process. This Phytotechnology has been applied since 1996 to a former sewage sludge dewatering plant in Schladitz near Leipzig (Fig 1). At the time of closing in 1990 about 300,000 m3 of heavy metal‐ and hydrocarbon‐contaminated sludge were stored on this site. It is the biggest phytoremediation project of this kind in Europe. An extensive monitoring and analysis program was established to evaluate the progress of the remediation (ending in 2012). Up to now the contamination of the site could be considerably decreased. The removal of heavy metals sums up to several kilograms with an increasing tendency over the last years (Fig 2). The aim of ongoing research activities is to set up improved conditions for an even more efficient extraction of heavy metal ions from contaminated soil and sediments. Optimizing this process should reduce the remediation period by up to two thirds. The technology is to be implemented not only in the Leipzig region but also in future remediation projects.
