Abstract
This paper describes the greening of ash dumps from two thermal power plants located in Romania, in the villages of Mintia and Doicești, two rural areas neighboring middle-sized cities, both with architectural, archaeological and landscape heritage. Currently, the two Romanian villages have different fates in the context of shrinking cities, and solutions from the industrialized country of Germany that are more advanced in closing polluting thermal power plants are examples of this. Thus, the greening of industrial waste is one of the current challenges of the energy shift towards renewable energy. Nature-based solutions such as the proposed use of the biodegradable geo-textile in the greening is one of the current trends. The development of the biodegradable geo-textile was contemporary with the creation of the International Building Exhibition (Internationale Bauaaustellung—IBA) Emscher Park in the ancient industrial coal mining Ruhr area, in Germany; later research, around 10 years ago, explored soil pollution at these two Romanian thermal power plants. A recent research study investigated the conversion of the industrial buildings of the thermal power plant in Doicești, however, these buildings were demolished at the end of last year. Mintia thermal power plant continues to function. This paper explores the current challenges of industrial brownfields, energy shift, ecology, the 21st yearly session of the Conference of the Parties (COP21) in Paris and “Laudato si”, spanning 30 years of history and the legacy of the research over this time.
Highlights
One of the uses of geo-textiles is to reinforce and stabilize steep slopes, for example, in the vicinity of transportation routes
Mintia is a village in the commune of Vetel, while Doices, ti is a commune with several villages
This paper presented a proposed solution to build blue-green infrastructure, by discussing this solution in the greening of two thermal power plants from the rural hilly areas of Romania
Summary
One of the uses of geo-textiles is to reinforce and stabilize steep slopes, for example, in the vicinity of transportation routes. This paper presents the safety measures and nature-based solutions for a different kind of slope stabilization: that of the ash dumps of thermal power plants, a fossil type of energy use, intended to be replaced by the above-mentioned renewable ones. Since the experiments were carried out to reduce the environmental impact of thermal power plants, the shift in energy transformed many such places into brownfields, and nature-based solutions for a blue-green infrastructure are considered suitable. A later study of greening solutions from the 1990s was conducted in the first decade of the millennium [5] and dealt with soil degradation from fly ash. The use of a biodegradable geo-composite was examined to see if the ash dumps can be covered to prevent environmental pollution. The two thermal power plants chosen for the studies were the ones in Mintia-Deva and in Doices, ti by Târgovis, te
