Background (1)Background (1)

Context of this paper - research project “Wood Supply and Economic Crisis: Impacts on the Forest-based Sector and Bio-Energy Production” [ECri-Wood; No. 13617] financed by the “Jubiläumsfond der Österreichischen Nationalbank” (Anniversary Fund of the Austrian National Bank).




Sciences




• Increasing competition between the uses of wood for energy and material purposes

• Need to have a complete picture of potentials

• Lack of data and lack of understanding of existing and potential wood flows (wood sources) sometimes produce wrong projections/predictions regarding the development of wood markets.




Sciences




• Many “traditional” forest sector models do not cover all wood flows relevant for physical purposes (manufacturing of goods) or for energy.

• Identification of wooden biomass flows most likely not covered in existing forest sector models

• based on the “Wood Resource Balance (WRB)” scheme developed by Mantau et al. (e.g. 2008a, 2008b) and on the Austrian “Wood Flow” scheme developed by the Austrian Energy Agency (Hagauer et al, 2007)

Waste PaperWaste Paper

Not taken into account by either WRB nor Austrian Wood Flow scheme, but would be important, because

• waste paper competes with wood pulp as an input in paper & paperboard production. This has an impact on the competition between as well as the availability of pulpwood and fuel wood.

• Waste paper contains a substantial amount of energy and can be (is) used directly for energy production itself.




Sciences



Waste PaperWaste Paper

• In the EU27 the recycling rate of consumed paper is about 67%, resulting in 48 mill. tons of recovered paper in 2009

• One ton of waste paper roughly represents 3.2 m3 roundwood equivalents. Therefore, in absolute figures, recycled (waste) paper in the EU27 represents approximately 154 mill. m3 roundwood equivalents.

• Waste paper largely (> 90%) consists of cellulose, while the share of cellulose in roundwood is only 30%+, the rest is lignin and hemicellulose. The latter two components cannot be recovered by the use of waste paper.




Sciences



• During the last years, the European data situation on wooden biomass has improved considerably regarding the possible linkage of forest sector and energy models – not the least through the introduction of the “Wood Resource Balance”.

• In order to develop an even more complete picture of wood-based fiber flows, it is recommendable to also include waste paper in the considerations.
