Wieruszewski M. , Mikołajczak E.

2018

tom No. 104

540--548

The work presents the results of character research and the share of by-products generated at the stage of processing the raw material timber in sawmill plants. For identification purposes individual forms of by-products and their participation in sawmill processes is important to separate the basic ones technological features that shape them. Type and quantity of by-products are primarily dependent on the type being processed raw material and production volume determining the technologies used processing. The research was carried out by means of a diagnostic survey, in selected ones wood industry plants processing round hart wood and softwood. Medium and small wood plants were included the most numerous group of sawmill enterprises. An analysis was made indicative and comparative. Depending on the species layout, it was established share of piece products degree of disintegration (chips, sawdust, wood dust, etc.). Factors that influence the quantity have been determined generated by-products for use own and for sale to wood biomass customers.

nr 1

The influence of variable indexes of material prices on costs in an enterprise is a significant element affecting the position of sawmill enterprises in the domestic wood industry. Apart from the price rise factor resulting from the increasing material deficit, the qualitative and dimensional characterisation of processed round wood is also significant. The influence of these factors is particularly important for medium-size enterprises concentrating on gradual technological development in order to maintain competitiveness on the market.
