Discussion panel concerning the issue of 'Bioenergy'
Wood Technology Institute in Poznań
organized a discussion panel in the research field of
in the Wood Technology Institute
The panel was organized within the framework of the project "Foresight in the wood science and industry - research development scenarios in Poland till 2020" co-financed by the European Union funds within the framework of the Innovation Economy Operational Programme 2007-2013.
The aim of the panel was to conduct an expert discussion which would give a strategic look at the future of the R&D sphere in the field of bioenergy, and especially issues concerning wood-biomass: its sources, market connected with logistic solutions and also economical aspects as well as gaining energy from it.
The meeting was a forum for exchange of thoughts about creating research in the field of bioenergy.

- Summary of the panel discussion
The panel discussion was attended by Observers - the Wood Technology Institute employees who deal with different aspects of bioenergy and a representative of the industry press, i.e. "Gazeta Przemysłu Drzewnego" ("The Wood Industry journal") and "Czystej Energii" ("Pure Energy").
In general participants of the panel emphasized the fact, that there is in Poland a large potential for creating fast growing plantations. They pointed out that there could be circa 2 millions ha of different kinds of areas for plantations (among others planted on formerly arable areas, uncultivated land). It was also claimed that nowadays it is not anticipated to grow plantations of that kind of trees for energy purposes on the The State Forests National Forest Holding's areas in the nearest future.The panel meeting was a animated constructive discussion. In the frame of anticipated in the programme problems concerning sources of the wood-biomass for energy purposes, panel's participants mainly discussed fast growing plantation trees for those purposes. The attention was paid to particular, continual problems connected with plantation running, therein especially: lack of adequate financial solutions (the question of additional payments), other technological problems concerning lack of adequate, modern equipment (used as well for cropping as for collecting trees, and also lack of equipment which is necessary for drying wood pulp, necessity of having adequate soil reach in water during plantation establishment (as weight gain green mass is connected with considerable water consumption).
Wood raw material from forest, which can be used for energy purposes, is fuel wood (a o. cordwood, branchwood). It accounts for about 11% of overall annual gaining of wood raw material from forests which are The State Forests National Forest Holding's property. Against that background it was emphasized, that forests are main source of wood for energy purposes.
The role of other sources of wood-biomass, such as: wood industry (industrial wood residues), households, public facilities, etc. (post-used wood residues, wood recycling) plantations (fast growing trees) even though is very important, is as of yet relatively remote.
During discussion about wood-biomass for energy purposes' market and logistic aspects it was emphasized that general usage of renewable energy sources, therein wood-biomass, as it is relatively new phenomenon, it comes up against many problems. The most important barrier is a capital costs one. In most cases investment outlays are very high and even though maintenance costs are relatively low, limitary investment cost's return period is very long.
The attention was drawn to the fact that main problems connected with usage of wood-biomass for energy purposes results from physical features of this energy medium and its dispersed localization: wood-biomass is very unstable fuel, of large humidity spread, what apart from difficulties with its combustion stabilization, has simultaneously great impact on profitability of its application as fuel. There are considerable territorial limitations in its access (distribution, logistic solutions). It is seasonal product and its too small density makes the transport, storage and dosage to furnace more difficult.
In the frame of subject area concerning technical and technological aspects of energy production from wood-biomass, participants emphasized that wood-biomass is still marginal source of energy in Poland. Wood-biomass direct combustion with acceptable economically and ecologically energy efficiency requires application of adequate technical solutions of energy installation, adjusted to fuel combustion at high share of volatile matter. Co-combustion of fragmented wood-biomass in the mixture with coal can be effectively realized in low power pots, used in individual heating as well as in industrial power engineering. It was also said, that usage of wood-biomass energy potential allows to economize nonrenewable fuel resources and it poses incentive of new technologies development.
In genera,l experts found out that subject of biomass usage for energy purposes, therein wood-biomass, has multi-faceted and prospective character. On one hand those problems are documented by many research studies, which point out positive influence (using biomass as a source of energy) on natural environment condition. They also encourage to work out and implement new technical and technological solutions. However on the other hand, economical inefficiency, connected especially with necessity of securing country's energy needs and natural environment are the reason for lack of further progress. Some organizational activities in the subject of spreading new solutions, rights and finances are required.
