Biomass, wood in particular, is one of the main renewable energy sources. The authors’ point of interest is the use of the orchard biomass, produced annually as a result of pruning the trees and shrubs, for the heating purposes, as such biomass is used for this purpose only to a little extent both in our country and in Europe. Such biomass, consisting mainly of branches and shoots, is usually shredded and left in the orchard interrows to serve as a natural fertilizer. This paper focuses on the reasons why it should be collected and removed from the orchard. It presents the technologies of pruning and collecting such biomass, and analyses the newest machine constructions that allow for fast collection and compaction of dendromass to the form which facilitates its storage and natural drying.
