MATERIAL FLOWS IN PRIMARY WOOD PROCESSING IN SLOVAKIA

Abstract

Material flow analysis was used to reveal and quantify relations between the resources and the primary uses of wood. The paper deal with the analysis of raw wood flows in Slovakia in two approaches to wood flow modelling were utilised - wood balance and wood resource balance. Wood balance was presented to demonstrate a general view of the resources and primary uses of roundwood without analysing internal flows. The wood resource balance, as a more detailed analysis, takes into account the uses of wood as a material and also the by-products and waste generated by the production that could be used as inputs for further uses in wood processing or energy sectors. The latter balance was compiled using available official statistics supplemented by a questionnaire to estimate missing data for waste streams with a total consumption of 10.78 mil. m3 roundwood.
