    A new type of renewable energy source derived from forestry

  • Original language description

    In forestry, dendromass for energy purposes can be obtained in the form of firewood. Alternatively, it can be sourced as so-called logging debris, which remains in the forest after logging trees, among other things, as stumps or roots. Stumps and roots are difficult to transport and contain a large proportion of soil and stones. One of the possible ways of stump extraction is with grubbing heads. Therefore, a new prototype of a grubbing head has been developed and it will be used to obtain logging waste from forest clearance areas. The advantage of this grubbing head is that it is possible to move the stump after it has been torn out, so that the soil is separated from the stump. The surface is then adjusted and aligned with the head. With the help of the excavator boom, parts of the stump are stored in piles, from which they are transported to the dendromass storage. After reaching 30% moisture, they are pulverized into energy chips, which are then taken to an incinerator or power plant. The resulting wood chips have an optimal calorific value and are presented as a renewable energy source produced from logging debris. After processing all the data, which are based on several field measurements undertaken, the average processing time of one stump was found to be three minutes. In one hour, an experienced operator is able to process up to 20 stumps on average.
