State of Brownfields in the Northern Bohemia, Saxony and Lower Silesian Regions and Prospects for Regeneration by Utilization of the Phytotechnology with the Second Generation Crops.

The need to achieve the sustainability goals and to reduce the continuous exploitation of the limited urban areas increases requests for the regeneration of brownfields. The current study aims to review the state of brownfields in the Northern Czech Region and neighboring German (Saxony) and Polish (Silesian) Regions which share a common geological background and environmental problems. The peculiarities of the brownfield's properties related to the term, classification, legislative framework, access to available data, degree of contamination, and remediation methods were the focus of this review. It was established that the state with brownfield identification and transformation is better in the Czech Republic, followed by Germany, with lower awareness in Poland. The relevant examples of successful brownfield revitalization and the importance of educational components were introduced. A prospective application of the phytotechnology with the second-generation crops for the remediation of brownfields was discussed. The utilization of Miscanthus spp. for marginal lands with low contamination can provide an economic return by having biomass converted into energy or bioproducts and the utilization of the accompanied waste as carbon-rich biochar which can indeed support phytoremediation, enhance plants' growth and serve as a medium for carbon sequestration. The next steps in the research have to concentrate on comparison of the rehabilitation methods introduced for the targeted regions with the global approach in brownfield redevelopment along with the practical ensuring the phytotechnology potential at the selected brownfields.
