Abstract:
In Romania there are large areas of land necessary to be greened and rehabilitated. By using the sludge a valuable land can be created from a degraded land, with the great advantage of allowing the fast fixation of the vegetation and reduces the soil erosion. The costs of capitalizing the treated sludge in land conversion and obtaining biomass is 210 ÷ 250 euro / ton dry. Development of pilot areas for the use of sludge in agriculture, forestry and land conversion and degradation and obtaining biomass are absolutely necessary. The use of sludge for the reconversion of degraded lands (closed mines, tailings dumps, etc.) is a feasible, recommended option; locally there is a special potential considering the existence of mining operations that have ceased their activity. The material from the mining tailings dump consists of clay-sandstone rocks, marls, coal shale and sandstones. The particle size of the material is very different, from millimetre dimensions to fragments of rocks with dimensions of centimetres or even tens of centimetres for the tailings from the mine. Forms of degradation identified on the tailings dump were: surface erosion, deep erosion, landslides, submerged surfaces, settlements and discharges.
