This study investigated the feasibility of extracting and chipping hardwood crowns for energy after motor-manual thinning in stands of common beech. Large crowns were extracted and chipped from stands where only sawlogs had been produced, while small crowns were extracted and chipped from stands where sawlogs and firewood had been harvested. The fuel chip yield was 15 m3 solid ha-1 when extracting and chipping large crowns, while it was 8 m3 solid ha-1 when extracting and chipping small crowns. The productivity for extracting and chipping large crowns was 8.5 m3 solid per workplace hour, and for small crowns was 5.9 m3 solid per workplace hour. Extracting and chipping large crowns gave a net income of €167 ha-1 (€11 m-3 solid), while extracting and chipping small crowns gave a lower net income of €23 ha-1 (€3 m-3 solid). The study showed that extracting and chipping large hardwood crowns is feasible and can make a substantial contribution to woody biomass feedstocks. Four product-mix alternatives were considered, but the marginal differences in outcome led the authors to recommend that in addition to sawlogs only one product, firewood or chips, should be produced in each stand.

Abstract
Development in surface mould growth on painted/unpainted wooden claddings and acting climatic factors were investigated over a period of 3 years. Eight wood substrates, including modified, preservative-treated and untreated wood, were tested in combination with three types of paint: (1) water-borne alkyd modified acrylic paint without fungicide; (2) solvent-borne alkyd paint without fungicide; and (3) ICP (internal comparison product). One set of samples was exposed unpainted. The samples were tested according to a modified version of EN 927-3. A logistic regression model was fitted to the data. The degree of mould growth varied with exposure time, coating typology, wood substrate, temperature and relative humidity. Exposure time and coating typology contributed most to the model. After 3 years of outdoor exposure unpainted panels and panels coated with solvent-borne paint without fungicide had more mould growth than panels coated with ICP and water-borne paint without fungicide. Unpainted oil/copper–organic preservative-treated claddings had higher resistance to mould growth than other unpainted wood substrates. Coated untreated pine and coated acetylated pine were more susceptible to mould growth than other coated wooden substrates.
