Lesni sekanci - pomembna oblika biomase v Sloveniji

Dominika Gornik Bučar (Author), Bojan Gospodarič (Author)

Abstract

Slovenija se je obvezala, da bo do leta 2020 v strukturi končne porabljene energije, delež energije, pridobljene iz obnovljivih virov, dosegel 25 %. Lesna biomasa poleg hidroenergije predstavlja najpomembnejši del obnovljivih virov energije v Sloveniji. Kljub temu, da je uporaba lesne biomase tradicionalna in da v zadnjih letih postaja vse pomembnejša, obstaja še vedno precej nejasnosti in nedoslednosti tako pri proizvodnji in prodaji, kot tudi pri nakupu različnih kategorij lesne biomase. Prispevek podaja informacije o spremenjenih kriterijih za lesne sekance različnih kakovosti, skladno z aktualnimi standardi. Preučili smo tudi različne načine trgovanja z lesnimi sekanci in prikazali prednosti in slabosti posameznega načina. Z izvedeno anketo smo želeli ugotoviti, na kakšen način trenutno nakupujejo lesne sekance večje kotlovnice v Sloveniji in v kakšnem obsegu se izvaja kontrola kakovosti lesnih sekancev. Ugotovili smo, da se z lesnimi sekanci večinoma trguje na osnovi volumna, ter da se kontrola lesnih sekancev ne izvaja sistematično.

Secondary title:	Wood chips - an important source of biomass in Slovenia
Secondary abstract:	Slovenia has committed to achieve a 25% share of energy from renewable sources in the structure of final energy consumption by 2020. Wood biomass, besides hydropower, is the most important part of renewable energy in Slovenia. Despite the fact that the use of wood biomass is traditional and has become increasingly important in recent years, there is still a lot of uncertainty about insufficient production in the sale as well as in the purchase of various categories of wood biomass. The article presents information on the changed criteria for wood chips of different quality, in accordance with the current standards. We also studied various ways of trading wood chips and pointed the strengths and weaknesses of each. With a survey we wanted to find out the current trading pattern of wood chips and implementation of wood chip quality control in larger boiler plants in Slovenia. We have found that most-used trading method of wood chips is on the basis of volume, and that the quality control of wood chips is not systematically performed.
