Increasing procurement volumes of forest biomass for energy require improved information systems to control and manage transportation. Moisture content of the biomass is the most important quality parameter to follow. Transportation of water in solid biofuels increases both costs and CO 2 emissions. Procurement operations need to be directed to sto...

Procurement systems and supply chains for industrial-scale forest fuel recovery are still immature. Business process improvement techniques can significantly improve system performance. The present study applies business process modeling and reengineering approaches to an integrated industrial roundwood and energywood supply chain in Germany. The e...

The EU should produce 20% of their energy from renewable sources, including bioenergy, by 2020. Each member state has their own target, for example, Finland should produce 38% and Sweden 49% of their energy from renewable sources by 2020. In this context, the development of forest energy utilization and more effective and economic supply systems pl...

Forest chips are becoming an important alternative resource for energy in Europe. The aim of this study is to review and analyze the current procurement methods and potentials of forest chips in Europe, based on questionnaires sent to relevant experts in different countries as well as a literature review of existing literature. The compilation of c...

This research analyses the productivity of energy wood chipping operations at several sites in Austria and Finland. The aim of the work is to examine the differences in productivity and the effects of the operational environment for the chipping of bioenergy at the roadside. Furthermore, the study quantifies the effects of different variables such...

There is common agreement that thinnings are necessary to achieve healthy and valuable stands. Thus, especially in intensively managed forests of the Scandinavian countries thinnings are an everyday practice. Furthermore, thinning removals have become an important source of energywood. That is why e.g. in Finland thinning operations are supported b...

At present, the utilization of timber in the Northern part of the Scottish Highlands is low due to a lack of a wood utilizing industry. As a consequence, the majority of forest owners do not receive any income from timber and in some cases stumpage prices can even be negative. At the same time, increasing prices of oil, gas and electricity pose a g...

Finland and Sweden have been forerunners in the development of wood harvesting machinery and methods. In both countries, small- and large-scale supply systems for wood chips have been in operation for several decades. More recently, the production and use of forest chips from logging residues and small diameter trees has been growing rapidly.The Eu...

The demand of woody biomass both for industrial and energy use in the EU is estimated to increase markedly in the coming decades to satisfy the material and energy supply of bio-based economy. Moving towards more mechanized harvesting technology induces needs to invest in harvesting machinery, which may decrease the labour input/harvested volume...

Wood storage Roundwood a b s t r a c t Research into the methods of producing high quality wood chips for a rapidly growing energy sector is becoming increasingly important. For example, small wood chip heating plants require high quality wood chips to ensure efficient operation, thereby minimizing maintenance costs. Moisture content is considered...

It is commonly agreed that logistics is very demanding in forest fuel business. Even though logistics and supply chain management (SCM) tools already have found their way into forestry business, for example, in roundwood operations, they are not yet very widespread in the field of forest fuel procurement. The present study investigates if modern su...

Due to fluctuating fossil fuel prices the use of forest biomass for energy is expected to increase considerably in the future. Today, the demand for high quality wood fuel products such as chopped firewood or pellets has increased price pressure on these products. In order to make the production more cost-effective new methods to optimize their pr...

Wood pellets have become an important fuel in heat and power production. The pellet market and supply structures are currently undergoing rapid development. Ensuring the quality of pellets through the whole production, delivery and handling chain is important in order to increase the use of pellets and sustain its ability to compete with other fuel...

In other chapters of this book, different economic, environmental and social aspects of forest fuel harvesting and wood ash recycling are treated and recommendations are given. However, national recommendations have already been elaborated by authorities in Sweden, Finland, Denmark and Lithuania (Billeschou & Klitgaard 1985, Danish Forest Agency 19...

This chapter introduces the principles of decision making at private forest ownership level and presents a decision support tool, EnerTree, for simple analysis of benefits and limitations of different forest residue recovery alternatives in Norway spruce and Scots pine monocultures. EnerTree is a forest stand level application which combines the av...

Forests provide an abundant, locally available and environmentally renewable source of fuel. However, their utilization has to be sustainable on an ecological, economic and social basis to ensure that future generations can utilize the forest resources with the same intensity. The benefits of wood as a fuel have been known throughout history and fo...

Bioenergy projects must be economically viable for the different actors in the value chain. Forest biomass used for energy purposes must be able to compete with other uses of the biomass, and at the same time the energy produced from biomass must be as cheap as or cheaper than energy produced from competing energy systems. The costs in these calcul...

The aim of the study was to investigate the effect of work experience on the accuracy and variation of observers recording the operation time of a harvester. A simulated thinning operation using a harvester, shown as video via a television screen in laboratory conditions, was observed by 20 inexperienced students and 10 experienced work study resea...

The substitution of biomass for fossil fuels in energy consumption is a measure to mitigate global warming, as well as having other advantages. Political action plans for increased use exist at both European and national levels. This paper briefly reviews the contents of recommendations, guidelines, and other synthesis publications on sustainable u...

The extraction of residues from the harvesting processes for energy production is common practice particularly in Finland and Sweden. Furthermore, the removal is expected to increase also in Central European and the Baltic countries. The extraction of forest biomass provides an extra source of income for the forest owner and positively affects the...

Harwarders, in which the work of a one-grip harvester and a forwarder is combined into one machine in CTL-loggings, are starting to compete for some logging operations with conventional machines. This new logging concept has opened a way to reduce logging costs for the contractors by allocating the logging sites to different machine concepts in a c...
