Biomass potential in Slovakia

Energy potential of biomass is high and it can reach theoretical 15 % of annual energy consumption in Slovak Republic, which is 800 PJ. Utilisable potential of solid biomass for heat and electricity in Slovakia is about 73 - 75 PJ, from that dendromass is about 45-47 PJ. From that about 17 PJ presents forest biomass, 18 PJ is biomass from wood-processing industry. About 47 % is covered by forestry biomass and 40 % by wood-processing industry.

Table 21: Utilizable potential of biomass for combustion

Kind of biomass	Amount in thousands tons	Potential in PJ
Forest biomass residues from forest management	1810	17
Wood-processing industries - mechanical processing (bark, off-cuts, sawdust)	950	12
Wood-processing industries - chemical processing	460	6,5
Biomass from communal sphere (urban biomass, communal wood waste)	300	3,2
Wood from selected energy forests and new short rotation plantation on cca 45 thous.ha	660	6,3
Dendromass	-	45
Solid agricultural biomass (straw, grain, vineyards) for combustion	2031	28,6
Total solid biomass	2031	73,6

The energy potential of biomass produced in agriculture is 12, 89 TWh or 46, 5 PJ (including 11 PT of biofuels for transport and 6, 9 PJ from biogas production). The utilizable biomass potential from agricultural plants (straw from cereals and rape seed, sunflower blades, the wood waste from gardens and vineyards) has a energy value 28, 6 PJ. The rest of vineyard sticks and rest from gardens are utilizable raw material too. According to the present quantification of agricultural biomass, approx. 2 mil. tons of a mass utilisable for energy purposes are disposable. The more detailed distribution is presented in database table 36.

Biomass from agricultural occurs mainly in the southern parts of Slovakia, which are the most productive in planting crops like rape seed, maize, and cereals. Permanent surplus straw are in the south part of Central Slovakia, region of Upper Nitra, Spiš and in lowlands of the East Slovakia.
