In this contribution, the results of experimental works assessing the share of bark in energy chips of selected clones of short rotation coppice of Salix viminalis and poplars with 5-year harvesting cycle, grown in the region of Slovakia and Moravia, are shown. Energy chips made of dendromass from fast growing trees grown on plantations is a bio-fuel consisting of juvenile wood and juvenile bark. The share of bark in energy chips influences the environmental properties and ash content of a bio-fuel.

The share of bark in energy chips from clones RAPP, OLM, ULV and Inger of Salix viminalis in bio-fuel is XB = 16,8 ÷ 19,7 % and the share of bark in chips from clones Max5, Oxford, AF2 a Monviso of poplars grown on plantations is XB = 20,97 ÷ 26,67 %.
