Available in PDF, EPUB and Kindle. Book excerpt: Woody biomass materials which include timber harvest residues, such as tree tops and small diameter trees, have the potential to be an important source of renewable energy. Their use as an energy feedstock or use as an input for other products is partly dependent on whether the materials can be harvested and transported to markets in a cost-efficient manner. In order to supplement the current knowledge base on woody biomass harvest systems, two integrated harvest systems, a whole tree harvest that extracted tops and a whole tree harvest that extracted tops and small diameter trees, simultaneously harvested woody biomass and conventional solid hardwood products (SHWP) on 30 acres of Missouri forestland. A mechanized system consisting of a feller-buncher, grapple skidder, and loader was used in both harvesting systems. Activity sampling and time-in-motion data were collected on all harvest machinery to determine system efficiency. Joint cost analysis was used to separate costs associated with harvesting SHWP and woody biomass. Marginal cost analysis was used to treat the tops of SHWP that were brought whole tree to the landing as a by-product of the SHWP. A sensitivity analysis was used to test the effects of changes of different costs on the cost per green ton of SHWP and woody biomass. Total cost estimates per green ton of material delivered to the landing at a 5% interest rate were $35.25 for SHWP and $5.76 for woody biomass in the whole tree (WT) harvest and $32.82 for SHWP and $8.81 for woody biomass in the whole tree with small diameter tree (WTSD) harvest. With the addition of a chipper, woody biomass costs increased to $11.11 per green ton in the WT harvest system and $14.16 per green ton in the WTSD harvest system.

Book excerpt: Questions have risen in recent years regarding the impacts of biomass harvesting for renewable energy production and on the cost and efficiency of biomass harvesting using different harvest equipment configurations. Missouri has a set of Best Management Practices (BMPs) to guide woody biomass harvesting. This study will address the different results (mainly cost and production data) that come with incorporating various BMPs and how costs and revenues can vary when implementing these different management practices. This study applied two silvicultural treatments and a control to 72 acres of oak-hickory stands comprising poles and small sawtimber-sized stems of primarily white oak (Quercus alba) and low quality black oaks (Quercus velutina) in the Missouri Ozark highlands. Treatments were: 1) clearcut to establish a new cohort of trees and 2) intermediate thin in an attempt to improve residual stand quality, in which both small diameter trees and merchantable sawlogs were removed. Both treatments used a mechanized, integrated harvest approach. Each treatment had 3 sub-treatments (clearcut had 4 sub-treatments) that called for leaving varying levels and types of residues on the ground to maintain soil nutrient pools. Trees were merchandized for the highest value possible, with biomass chips produced from limbs and tops or stems that were otherwise unmerchantable. A system feasibility analysis was implemented to determine productivity, costs, and prices needed for economic feasibility. An average of 49.4 tons of SHWP and 10.9 tons of fuel chips were removed per acre at an average cost per ton of $27.70 and $48.62 in the clearcut treatments, respectively. An average of 19.1 tons of SHWP and 3.7 tons of fuel chips were removed per acre at an average cost per ton of $32.87 and $64.84 in the intermediate thinning treatments, respectively.

This book was released on 2010 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: An integrated mechanized timber harvest thinning treatment to remove small diameter trees and merchantable saw logs was conducted on 30 acres of the Missouri, Ozarks in the summer of 2009. Two silvicultural treatments (single tree selection and shelterwood strips) were applied to reduce basal area to different levels. A harvest system feasibility analysis was completed to estimate productivity, costs, and prices needed to attain economic viability (breakeven point). Time in motion data was collected on all system components to understand how the extra efforts to gather small diameter and slash material affect the cost structure of a mechanized timber harvest thinning. A sensitivity analysis was conducted to find breakeven points at varying diesel input costs, equipment purchase costs, hauling distances, stumpage costs and government subsidy. Results indicate that an average of 15.50 tons of fuel chips and 35.72 tons of solid hardwood products was removed per acre. The cost per ton to harvest, skid and process at road side for the fuel chips and solid hardwood products was $19.20 and $11.17 per ton respectively. Contracted fuel chips hauling cost was $12.00 per ton and solid hardwood hauling averaged $4.16 per ton. Stumpage was assumed to be $5.00 and $9.95 per ton, respectively. Average price at the gate for these two products were $26.00 per ton and $32.64 per ton leading to a profit/loss of $-10.20 per ton and $7.36 per ton for the fuel chips and solid hardwood products respectively. Losses from fuel chips were less than the profits from the solid hardwood products resulting in a net profit of $3,131.76 dollars. Keywords: woody-biomass, forest thinning, integrated harvest, single tree selection, shelterwood strips, economic feasibility, sensitivity analysis.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The importance of bioenergy, particularly woody biomass, continues to gain significance in Missouri. Although physical estimates of standing wood have been used to assess and project total above-ground woody biomass, these estimates fail to explore its social availability. Over 85% of Missouri's forests are privately owned, indicating that without the state's private landowners' acceptance utilizing woody biomass as bioenergy feedstock to the energy industry is impossible. Data was collected through focus groups and a mail survey, following the Tailored Design Method, to determine the states level of social acceptance towards woody biomass harvesting. Factor and cluster analysis were conducted to provide a current typology of Missouri's Non-industrial Private Forest Landowners (NIPFLs) as well as analyze the impacts of dominant timber prices and government incentive payments. Ordinal probability regression models and a marginal effects analysis determined the percentage of socially available woody biomass feedstock in Missouri as a function of timber and biomass prices, subsidy payments, and demographic profiles. Although results indicate many landowners are not knowledgeable about woody biomass for energy, they are interested in learning more about its potential uses. Results also suggest that landowners will sell their timber and woody biomass if the prices are sufficiently high enough in those markets. Today's market prices however are not deemed adequate to interest NIPFLs whose primary objectives include conservation/recreation rather than forest management.

This book was released on 2015-01-03 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Woody biomass can be used for the generation of heat, electricity, and biofuels. In many cases, the technology for converting woody biomass into energy has been established for decades, but because the price of woody biomass energy has not been competitive with traditional fossil fuels, bioenergy production from woody biomass has not been widely adopted. However, current projections of future energy use and renewable energy and climate change legislation under consideration suggest increased use of both forest and agriculture biomass energy in the coming decades. This report provides a summary of some of the existing knowledge and literature related to the production of woody biomass from bioenergy with a particular focus on the economic perspective. The most commonly discussed woody biomass feedstocks are described along with results of existing economic modeling studies related to the provision of biomass from short-rotation woody crops, harvest residues, and hazardous-fuel reduction efforts. Additionally, the existing social science literature is used to highlight some challenges to widespread production of biomass energy.

Available in PDF, EPUB and Kindle. Book excerpt: Non-industrial private forest (NIPF) landowners control 58% of all forests in the U.S. Great Lakes States consisting of Michigan, Minnesota and Wisconsin. A regional assessment of the availability of woody biomass for bioenergy will therefore be incomprehensive without a consideration of supply from the most dominant ownership group. This study aimed to evaluate the social availability of woody biomass for renewable energy in the U.S. Great Lakes States by examining NIPF landowners' willingness-to-harvest (WTH) their woodlands. Following the Tailored Design Method, surveys were mailed to 4,190 NIPF landowners from Michigan, Minnesota and Wisconsin. Results identified two latent factors summarizing landowners' bioenergy perceptions: (a) bioenergy support and (b) environmental degradation and four latent factors behind woodland ownership: (a) amenity, (b) personal use, (c) production and (d) legacy. A two-step cluster analysis approach was used to construct a landowner typology for the region based on landowners' bioenergy views and reasons for woodland ownership. Four types of landowners were consequently identified: recreationist, indifferent, preservationist and multiple-objective. Recreationists were found to own the majority or 51% of the total woodlands reported by sample respondents and were also most willing to harvest their woodlands with an estimated 38% potentially available for timber harvest and 46% for biomass harvest. A comparison of WTH by landowner type and state revealed that the greatest level of acceptance as indicated by potential acreage availability were from recreationists owning NIPFs in Michigan. Binary logit regression models were also used to determine significant factors influencing landowners' WTH timber and woody biomass. Findings indicated that non-timber objectives decreased the odds of harvesting and timber and biomass prices increased those odds. However, marginal probability effects of prices on WTH highlighted the substantial impact that timber price, rather than biomass price had on landowners' choice to harvest. These results suggested that the availability of woody biomass will be contingent upon timber prices.
