Opis:: Co-pyrolysis characteristics of sludge with coal and sludge briquetted with coal were studied by the TG-FTIR method. From TG data, weight loss of sludge briquetted was higher than that of sludge and sludge and coal which means that thermal reaction effect of sludge briquetted is better than those of other two materials. Gas products of pyrolysis were CO, CO2, H2O, alcohol, ketone, acid, hydrocarbon, amine and azine from the FTIR analysis. At last, evolving patterns of the pyrolyses and the yields of their gas products have been recorded, providing extremely important data on the mechanism of the process.

Opis:: Sewage sludge management in Poland is a major environmental problem. The preferred solution to this problem may be co-combustion of sludge with coal in existing power plants. The paper presents the current legal basis and the benefits associated with the recognition of sewage sludge as renewable energy carrier and biomass with zero CO2 emission factor in the processes of coal cocombustion. Energy parameters of sewage sludge resulting from its organic fraction, which is mostly biodegradable material, have been characterized. The results of investigation of the biodegradable fraction content in sewage sludge by the method of selective dissolution have also been presented.

Opis:: The presented work aimed at evaluating a fertilizing mixture of sewage sludge, brown coal and brown coal ash enriched with potassium mineral fertilizer on mobility of heavy metals. The effects of fertilization were compared with the effects obtained from fertilization with: sewage sludge, mixture of sewage sludge and mineral fertilizer, mixture of brown coal and mineral fertilizers and mineral fertilizers. Soil was slightly contaminated with zinc and cadmium (II°) and showed elevated concentration of lead (I°). The uptake of heavy metals by plants depended on the concentration of bioavailable metal forms determined with 0.01 M CaCl2 and 1 M HC1. Fertilization with the mixture of sewage sludge, brown coal, brown coal ash enriched with potassium mineral fertilizer resulted in the reduction in the concentrations of zinc by 30-38%, cadmium by 28-34% and lead by 11-50% in plant biomass compared to soil with no fertilization.
