“…Similar results were found by Lehtikangas (2001), who found that besides suitability, bark pellets have excellent durability and tolerate moisture well. Melekhov et al (2015) studied the energy potential of bark in a resource-saving program, suggesting the thermomodification of birch bark for changes in physical-mechanical properties, which greatly simplifies further technology to turn it into pelletized fuel. Gil (1997) suggested using the waste and dust produced during cork processing to generate energy because it has high calorific value.…”

“…According to Feng et al (2013), in Canada more than 17 million m 3 of bark is produced yearly, and more than half of it is burned or delivered to dumps. The amount of bark removed from lumbered wood in Hungary reaches 500 to 600 thousand m 3 (Molnár 2004), and, in Russia, approximately 30 million m 3 yearly (Ushanova 2012;Melekhov et al 2015). Quantifying the exact amount of bark produced annually is a complicated problem; despite strenuous efforts, its quantification involves considerable uncertainty, as only a small proportion of bark is traded.…”

The utilization of natural raw materials has been practiced for centuries. Of raw materials, wood and its bark have outstanding significance because of their special chemical components and unusual structure. Annual bark production is estimated to be between 300 and 400 million m3. The bark of different tree species has been used extensively in or in conjunction with modern technologies. This article presents a comprehensive summary of these methods of utilization and their results. The diversity of bark utilization derives from the variety of the bark of different species and from the possibilities encoded in the material. Following the anatomic summary, the protective role of the bark is discussed, highlighting its physical-chemical properties and the different methods of medical, energetic, and industrial utilization.

The problem of industrial use of tree bark is relevant and has practical importance for complex processing of wood raw material. Barks are available in Hungary and Russia in large quantities, but they are not widely used for different purposes than producing energy. One of the perspective areas of utilization of tree bark is its use as raw material for the production of thermal insulation panels. The present study focuses on the thermal insulation capacity of tree bark. Thermal conductivity properties of two broadleaved (black locust (Robinia pseudoacacia), pannónia poplar (Populus euramericana cv. Pannónia)) and three coniferous (larch (Larix decidua), spruce (Picea abies) and scots pine (Pinus silvestris)) tree species were examined. Based on these results, the scopes of the tested species were further narrowed, while the best results showing black locust was used for pressed insulation panel. Three different fractions were produced made of grained black locust bark. Furthermore, the heat insulation capacities of bark were investigated by compressing the chipped bark particles until the lowest heat conductivity was reached. Results show a competitive thermal insulation property to the traditionally used insulation materials, the value was 0.0613 W/mK reached by black locust bark chips. The broadleaved tree bark chips have a lower thermal conductivity than coniferous species. By using fine, mid, and coarse fraction of black locust bark were produced and the difference of thermal conductivity between them was negligible. Although the fine fractionated black locust bark chip thermal conductivity was 0.042 W/mK.
