    Opis:
    Biologiczna metoda utylizacji przez kompostowanie odpadów o dużej zawartości substancji organicznej, do których zalicza się wszelkie odpady drzewne, jest sposobem ponownego włączenia materii do naturalnego obiegu w przyrodzie. Celem doświadczeń było określenie wpływu dwóch wariantów kompostów (OPA) i (OPB) uzyskanych z pokonsumpcyjnych odpadów drzewnych na wzrost oraz stan odżywienia sałaty i bazylii. Rośliny uprawiano w samym kompoście i w podłożach, w których komposty mieszano z glebą mineralną w stosunkach objętościowych 1:1 lub 1:3. Kontrolę stanowiły rośliny uprawiane w glebie mineralnej oraz w substracie torfowym TS-1. Największe plony sałaty i bazylii otrzymano z uprawy roślin w substracie torfowym, a najmniejsze w samych kompostach OPA i OPB. W podłożu z dodatkiem 50% lub 25% kompostów plon roślin był większy lub porównywalny do uzyskanego w glebie mineralnej. Zawartość makroskładników zarówno w liściach sałaty jak i bazylii zależała od rodzaju zastosowanego podłoża.
    Biological utilization of waste with a high content of organic matter, which include all the wood waste, by method of composting is a way to re-enable the matter to the natural cycle of nature. The aim of experiments was to determine the effect of two variants of the compost (OPA) and (OPB) obtained from post-consumer wood waste on the growth and nutritional status of lettuce and basil. Plants were grown in the compost or in substrates in which the compost was mixed with mineral soil in the relations of 1:1 or 1:3 by volume. Control plants were grown in mineral soil and peat substrate TS-1. The highest yields of lettuce and basil were obtained from plants growing in peat substrate, and the smallest in the pure composts OPA and OPB. In the substrate with 50% or 25% compost plant yield was greater than or comparable to that of the mineral soil. Macronutrient content of both lettuce and basil depend on the type of substrate.

    Opis:
    No separate legislative acts are in force in Poland or the European Union that would regulate waste wood issues directly. Therefore, the analysis presented in this paper concerns legislation applying generally to waste, including waste wood. The issues discussed include terminology, classification and waste wood management. Pursuant to Directive 2008/98/EC, waste is any substance or object which the holder discards or intends or is required to discard. This definition of waste has remained unchanged in the amended Waste Act in Poland. Waste classification issues are partly resolved in the European Waste Catalogue. A national waste catalogue has been created, in which waste has been divided into 20 groups, depending on the source from which it is generated. Waste wood has been allocated to seven groups, and in particular to group 03. It is worth mentioning that the catalogue does not include a number of wood waste groups, namely OSB, fibreboard, plywood, board cutting waste, as well as products made from them, etc. This leads to problems with the interpretation of regulations concerning, in particular, the combustion of biomass. The priority task in waste management is waste prevention, followed by the preparation of waste for reuse, its recycling and finally other recovery methods, i.e. energy recovery or waste disposal. In view of the above, energy recover, as well as the reprocessing of waste into materials to be used as fuel or for backfilling or landfilling operations, is not a form of recycling. In spite of these assumptions, legislative acts are in force which regulate actions aimed at increasing the use of waste wood for energy recovery purposes. Regulations promoting the use of waste wood for energy recovery purposes can also be found in Polish legislation. The paper points out to the absence of clear and comprehensive legal solutions concerning waste wood management. This situation results in serious difficulties in the rational use of waste wood as one of the main sources of timber. It also leads to problems with estimating the quantity of waste wood and, consequently, prevents the correct assessment of its potential for use by particular sectors of the economy.

    wastes from forestry
    post−industrial waste wood
    post−consumer waste wood
    Opis:
    Timber harvesting and wood processing are inseparably accompanied by various waste production. Waste wood, in the form of remains of tree care and correctly conducted logging operations, may be a product of forestry activities. It includes branches, boughs or rootwood. Post−industrial waste wood varies in form and the degree of shredding, and in terms of its contamination with both chemical compounds and mechanical or mineral pollutants. Daily living activities are a source of post−consumer waste wood, including demolition wood and furniture, the management of which is the most challenging task. Agricultural crop waste is a category that is often overlooked. It includes pruning waste, waste being an effect of plant regeneration in orchards and soft fruit plantations, or field or roadside shrub removal. The difficulty with assessing potential quantity of waste wood is to large extent caused by the lack of rational and comprehensive legal solutions. It should be noted that waste holders generating up to 10 t of sawdust, wood particles, wood, waste particleboards or veneer, or up to 10 t of waste bark or cork annually, are not obliged to keep a record of such waste. Another important factor hindering the determination of the supply of waste wood in Poland is the lack of a clear system of its classification. Consequently, there is no data concerning waste wood quantity. Considering the supply of wood materials and products, their characteristics and intended use, we can assumed that the greatest quantity contaminated waste is generated by furniture and wood−based panels industry. The paper also points out the inconsistencies in the literature regarding the determination of the potential waste wood base. In general, approximately 8.0 million m3 of post−industrial waste wood are generated in Poland every year. The supply of post−consumer waste wood is at a level of approximately 5.3 million m3. The supply of wastes from forestry and agricultural crop waste equals 3.8 million m3 and 0.4 million m3, respectively. So approximately 18.0 million m3 of waste wood, varying in terms of origin, form and properties, may be generated in Poland annually. Considering the wood shortage that can be observed in Poland, as well as the substantial quantities and availability of waste wood, these two latter factors may constitute an alternative source of wood raw materials for a number of sectors of the economy.
