Surface regeneration of coal tips: 15 years of mine rehabilitation in a former coal mining region in Southwest Germany
This paper presents observations centered on an EU project dealing with coal spoil re-vegetation,emphasizing the use of sewage sludge mixed with wastes from other industries to form artificial top soil for field emplacement—specifically on both flat surfaces and slopes on coal tips at Reden and Duhamel in the Saarland region of Germany.It indicates that stable fertile soil can be created even on steep slopes.From developments over some 15 years (particularly at the Reden site),time has shown the original restoration on the tips was largely successful with planted species providing a lasting green surface with progressive replacement of planted species by natural ruderals.Some woody shrubs became naturally established,but,within the time frame of the development,there was little evidence of substantive natural succession to include woodland trees.Even though regulation in Germany now discourages spreading of sewage products,the success of the technology provides a potentially economic methodology for the effective long-term surface restoration of brownfield dumps elsewhere.
