Miscanthus Giganteus as an Auxiliary Raw Material in NSSC Birch Pulp Production

“…The average lengths of miscanthus fibers (1185.8 µm), fiber diameters (16.2 µm) and lumens (8.64 µm) were similar to those reported in the literature data. 9,17 The results obtained for the measurements of the mean values for the slenderness coefficient (77.2), flexibility (49.3) and Runkel coefficient (1.3) were also similar to those in the paper by Ververis et al 17 Comparative statistical analyses showed that the miscanthus fibers were characterized by similar flexibility and Runkel coefficient, but had a higher slenderness index than that of birch fibers. The average value of Runkel coefficient was higher for miscanthus, but differences in the cell wall thickness resulted in measured values that were characterized by a high coefficient of variation (Fig.…”

“…So far, relatively little research has been dedicated to obtaining pulp from miscanthus, including mainly via sulfate, sodium and high-yield TMP and CTMP processes. [4][5][6][7][8][9] The production of neutral sulfite pulps has been the subject of an even smaller number of studies. 10,11 The results of our previous comparative studies on neutral sulfite pulping of Miscanthus giganteus and birch wood indicated that this raw material is subjected to relatively rapid delignification and has a slightly lower pulp yield as compared to birch.…”

Forest Dendromass as Energy Feedstock: Diversity of Properties and Composition Depending on Systematic Genus and Organ

“…Given the non-uniformity of the dendromass composition, with the simultaneous exhaustion of the fossil fuel resources, forest area shrinking (and deterioration of its condition), as well as striving (also of the society) for a transition to forests performing ecological functions [23,24], studies need to be taken up covering the diversity of the thermophysical properties and elemental composition of that bioenergy feedstock. This is especially so since the chemical composition of forest trees is not only affected by the systematic genus but also by the plant organ, morphological part, age, time of acquisition, origin, and environmental conditions of growth.…”

Phytostabilisation of tailing ponds with use of water absorbing geocomposites and organic and mineral additives

“…The most important of which are ash and moisture content. In this study, the results are lower, on average by 2.5 MJ•kg -1 DM than the typical values from grass grown in arable land (Table 4) [21]. The conducted experiment demonstrated a significant influence of tailing additives on the calorific value of reclamation plants.…”
