Download or read book Woodchip Supply System Options for Remote Communities written by Bruce McCallum and published by Sault Ste Marie, Ont. : Great Lakes Forestry Centre. This book was released on 1999 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is intended to assist Aboriginal communities, particularly in remote areas, to examine whether fuelling small heating systems with wood biomass is a viable option. It provides the basis for communities to begin to design and explore wood chip supply operations which suit their individual needs. The report defines biomass energy and describes some of the benefits of biomass energy heating systems, as well as some of the challenges of supplying wood chips in remote communities. Two wood chip supply options are examined: using conventional forest machines such as skidders, dump trucks, and wood chippers; and using conventional agricultural machines, such as tractors, with forestry attachments. Information on these options is presented with respect to planning & selecting a wood chip supply system, advantages, limitations, and estimated costs. Chipping of wood and the operation of wood chippers are also described. Includes glossary.

Download or read book How Wood Chip Size Affects Pretreatment Effectiveness of Woody Biomass for Biological Processing written by Jerry Tam and published by . This book was released on 2013 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Woody biomass is particularly resistant to breakdown and must be size reduced to make pretreatment with steam, acid, or other chemicals effective. However, because mechanical size reduction of woody biomass can consume significant amounts of energy, it is important to understand how to minimize size reduction, while still realizing high sugar yields from the combined operations of pretreatment and enzymatic hydrolysis. Thus, this study focused on determining how sugar yields change with particle size. Downscaled composition analysis and enzymatic hydrolysis were applied to different sized wood chips and powder of Populus tremuloides to examine whether wood chips could perform similarly to powder. It was found that above a certain pretreatment severity range (R0=3.8), large wood chips could give higher enzymatic sugar yields, so that size reduction is not always required, thus saving energy. Furthermore, models were applied to better understand whether heat transfer affected pretreatment effectiveness and establish maximum dimensions for high sugar release.
Download or read book Bioenergy from Wood written by Thomas Seifert and published by Springer Science & Business Media. This book was released on 2013-12-02 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for scientists and practitioners interested in deepening their knowledge of the sustainable production of bioenergy from wood in tropical and sub-tropical countries. Utilising the value chain concept, this book outlines the necessary aspects for managing sustainable bioenergy production. A wide range of topics is covered including biomass localization, modelling and upscaling, production management in woodlands and plantations, and transport and logistics. Biomass quality and conversion pathways are examined in order to match the conversion technology with the available biomass. A section is dedicated to issues surrounding sustainability. The issues, covered in a life-cycle assessment of the bioenergy system, include socio-economic challenges, local effects on water, biodiversity, nutrient-sustainability and global impacts. Through this holistic approach and supporting examples from tropical and sub-tropical countries, the reader is guided in designing and implementing a value chain as the main management instrument for sustainable wood.
Download or read book Utilization of Residual Forest Biomass written by Pentti Hakkila and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increase in the demand for wood results in improved recovery and less residual biomass in the forests. Paradoxically, interest in forest residue as a renewable source of raw material seems to be in a reverse ratio to its availability in a certain area. Finland and Sweden are probably more dependent on forestry and forest in dustries than any other developed countries in the world. A sufficiency of raw ma terial for integrated forest industries is vital for the national economy of both countries, and a great deal of attention is being paid to the long-term potential of unutilized biomass left behind in logging operations. Furthermore, since these countries possess no reserves of fossil fuels, and since their per-capita consump tion of primary energy is exceptionally high, they also consider unmerchantable forest biomass a realistic source of indigenous energy. A joint Nordic research project on harvesting and utilization of logging residue was carried out in 1969-1976 under the auspices of the Nordic Research Council on Forest Operations. This fruitful cooperation soon gave rise to related national projects in Sweden, Finland, Norway, and Denmark, stimulating further research and producing practical applications. Concurrently, particularly after the worldwide energy crisis in 1973, research on all aspects of utilization of forest bio mass mushroomed in the United States, Canada, and the Soviet Union. An ex plosive increase occurred in both the number and diversity of biomass studies.

This book was released on 2013-11-08 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2011 in the subject Business economics - Investment and Finance, grade: 1,5, The University of North Carolina at Wilmington (Cameron School of Business), course: Master of Business Administration, language: English, abstract: The European demand for wood chips and wood pellets is strongly increasing in the course of a new energy policy. This new policy limits the use of non-renewable energy sources to a maximum of 80 % in favor of a 20 % renewable energy mix by 2020. Besides the main renewable energy sources, wind and hydro, woody biomass shall contribute the largest part of the generation of heat and power. As North West European wood resources are not sufficient for this sudden demand, the region relies on imports from abroad. The large renewable wood resources of the North American continent could be used increasingly to supply woody biomass to North West European countries like Germany. This thesis analyzes the profitability of US American exports of woody biomass to Germany. To see under which conditions the transport has its maximum rate of return, four trans-porting categories are investigated. Firstly, it will be analyzed whether the woody biomass should be compressed to pellets, secondly which type and cargo handling features the vessel should have, thirdly which charter conditions, harbors, trade terms, and routes should be taken and fourthly, which market conditions under current market prices for energy wood, variation of exchange rates and fuel oil prices are favorable, to improve the efficiency of the transport. Be-yond that, also the Canadian exports have been analyzed in order to benchmark the market leader against the USA.

Download or read book Wood Energy in Developed Economies written by Francisco X. Aguilar and published by Routledge. This book was released on 2014-08-27 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a recent resurgence of interest in wood energy as part of a sustainable range of renewable energy options. This book addresses the current gap in the energy and public policy literature for a reference book that compiles the most-recent wood energy assessments, and evaluates current and potential future wood energy uses and the role for public policy to foster efficient use of the most-widely consumed renewable energy in the world. It brings together a group of expert authors covering topics from forest management, operations and engineering, to socio-economics and energy policy perspectives. It thus covers practical issues such as silviculture, harvesting, processing, comparative cost estimates, public policy tools and market effects. As such the book provides a comprehensive review of the complex dimensions of wood energy as well as practical guidance for professionals, researchers and advanced students. It will also provide invaluable guidance for economic development agencies, practitioners and policy-makers, when evaluating the impacts of wider wood energy adoption as part of a strategy for sustainable energy generation. The main focus is on industrialised production and developed economies, particularly the USA and Europe.
