ABSTRACT
When treating sugar beet by modem mechanical procedures, from the phase of picking up to processing, the considerable amounts of plant refuses are left. The refuses such as sugar beet leaves, fragments, tails and grass, if processed or preserved adequately, can be used as animal feed. The additional economic and ecological problems are created if this refuses are used inadequately. The possible utilization of Ca-ions from CaSO4 in pressing waste biomass from sugar rafineries was investigated in this work. The aim was to obtain the pressed pulp with increased content of dry matter and press juice with satisfactory feeding value. The efficiency of pressing of the organic refuses from sugar industry can be improved by the use of CaSO4 as additional chemical agent and with heating the disintegrated mass. When using 680 g CaSO4/t of biomass and by heating up to 60°C, the yield is 35 t of pressed pulp containing 31% dry matter and 65 t of press clear juice with 11% dry matter from 100 t of processed biomass.
