Abstract
The work solves scientific problem of decontamination of the soil using biomass. Our investigation was subject to Cu, Pb, Hg and As with aim to examine whether plants are able to accumulate heavy metals. The laboratory experiment was performed in order to determine heavy metals content is the soil before plast sowing and after is harvesting. Amaranth (amaranthus) was used as a bioaccumulator. As significant amount of the heawy metals is accumulated in the root, there arise task to harvest plant and its root. Roots leaving in the soil mean retrograde contamination after the plant decomposition. But, there is lack of agricultural machinery able to harvest amaranth together with the root. Next part of the study is focused on the amaranth utilization as energy. Energy value is comparable with other biomass materials as wooden sawdust, grain straw etc. The final phase of the research is dealing with means suitable to trip the solid remainders after burning in the smoke.
