Ecological restoration studies of some biological inert, hazardous waste

In this study, the results of research on ecological restoration of a deposit of 150ha of fly ash and
boiler slag are presented. The nutrients for plant growth were done with organic fertilizer,
slaughterhouse sludge. Stimulation of vegetation was done with an agent based on brown algae
extract. The study was conducted over two successive years. Plant growth was performed in
fertilization variants with optimum amount of10t/ha slaughterhouse sludge with growth stimulus.
The stimulus advantages have been the increase of seed amount of up to 37% and reduction of
plant toxic metal content i.e. for Pb with 62.1%.
