Abstract:
Using woody biomass from public lands could attract private investments, increase carbon dioxide emission reductions from sustainably harvested low-grade wood to mitigate climate change, provide benefits for the environment, and support rural community economies. Available for use are about 210 million oven dry tons (in the western U.S. alone) of small-diameter wood and harvest residues that could be removed through hazard-fuel treatments and used for bioenergy and bioproducts; representing an economic value of approximately USD 5.97 billion (109). Reaching that utilization goal requires an assessment of current U.S. policies, regulations and directives influencing the use of forest biomass and identification of barriers, challenges, and potential opportunities associated with the use of woody biomass from public lands. One objective of this review is to support the implementation of the U.S. Department of Agriculture, Forest Service (USDA-FS) new effort called “Confronting the Wildfire Crisis: A Strategy for Protecting Communities and Improving Resilience in America’s Forests”, but greater coordination of public policies (regulatory legislation, government subsidies, support programs) at different government levels could increase adoption of forest biomass for bioenergy and bioproducts while also promoting different supply chains for long-term biomass supplies and industry investments. Harmonizing the definition of key biomass terms used by different programs that support using forest biomass for bioenergy and other bioproducts, including the Renewable Fuel Standard, may increase forest biomass use from public lands.

Abstract:
The bioeconomy is expected to replace the current information economy and will depend heavily on the manufacturing and trade of bioproducts, which are all commodities generated by living organisms through the use of technology and biotechnology, as well as non-timber forest products. In Canada alone, markets for bioproducts are in excess of $100 billion annually. The bioeconomy should impact most of Canada's economic sectors: energy and transportation, food and agro-food, pharmaceuticals, nutraceuticals, forestry, materials and manufacturing, waste management and a large variety of consumer goods. The bioeconomy holds promises to wean the Canadian economy from its dependence on fossil fuels as a primary source of energy as well as platform chemicals in materials and manufacturing, while meeting the Kyoto commitments on greenhouse gas reductions. Finally, the bioeconomy will reduce the environmental impact of economic growth by increasing the use of industrial and urban wastes and developing goods that are biodegradable.

Abstract:
Advanced Hardwood Biofuels Northwest (AHB), a USDA NIFA-funded consortium of university and industry partners, identified southwestern Washington as a potential location for a regional bioproducts industry using poplar trees (Populus spp.) as the feedstock. In this qualitative case study, we present the results of an exploratory feasibility investigation based on conversations with agricultural and natural resources stakeholders. This research complements a techno-economic modelling of a hypothetical biorefinery near Centralia, WA, USA. Interviews and group discussions explored the feasibility of a poplar-based bioproducts industry in southwestern WA, especially as it relates to converting land to poplar farms and the potential for poplar to provide ecosystem services. Stakeholders revealed challenges to local agriculture, past failures to profit from poplar (for pulp/sawlogs), land-use planning efforts for flood mitigation and salmon conservation, questions about biorefinery operations, and a need for a new economic opportunity that “pencils out”. Overall, if the business model is convincing, participants see chances for win-win situations where landowners could profit growing poplar on otherwise low-value acreage and achieve ecosystem services for wastewater or floodplain management.

Abstract:
Forest site classification is a prerequisite to successful integrated forest resources planning and management. Traditionally,site classification has emphasized a phytocentric approach, with tools such as the site index having a rich and longhistory in forest site evaluation. The concept of site index was primarily devised to assess site productivity of an even-aged,single-species stand. Site index has been the primary method of forest site evaluation in support of management for traditionalforest products. However, this method of site classification has been criticized as the needs, perspectives andsocial values of the public regarding forest management have changed the emphasis from timber production to multiplevalueforestry practices. There are alternative approaches to forest site classification that have the potential to meet thegrowing demands placed on forest information for inventory and modeling purposes. Ecological Land Classification(ELC), is a phytogeocentric approach that stratifies the landscape into ecologically meaningful units (ecosites) based onsubstrate characteristics, moisture regime and canopy composition. This approach offers a more holistic view of site productivityevaluation; however, until recently it has been difficult to acquire data to support widespread mapping ofecosites. Remote sensing technology along with predictive modeling and interpretive mapping techniques make the applicationof an ecosite-based approach at the forest landscape level possible. As forest management moves towards the considerationof a broader set of resources (e.g., woody biomass), there is an opportunity to develop new tools for linking forestproductivity to the sustainable production of forest bioproducts with forest ecosites as a solid foundation forsegmenting the landscape.

Abstract:
Abstract There is growing interest in harvesting forest biomass to meet the needs of bioenergy and bioproducts facilities in the Northeast. This interest is accompanied by increased concern over the potential impacts of biomass removals on forest ecosystems. Debates over biomass proposals have revealed a considerable level of confusion over the term biomass harvest, much of which stems from ambiguity surrounding the term forest biomass. Indeed, all forest material removed during harvest is forest biomass, yet many view only a small portion of this—typically low-value chipped material—as biomass. Since much of this material is destined for use as energy, we feel that communication among the public, foresters, academics, and industry representatives would improve by referring to forest biomass of this nature as what it really is: energy wood. Once terms are clarified, it is easier to understand how concerns with market dynamics, soil productivity, water quality, and forest biodiversity can be addressed through forest policy development.

Abstract:
The use of by-products from agricultural and forestry activity, apart from many other environmental benefits, constitutes an alternative source of income, cost reduction, and support for the principles of the circular economy. The bobal grape is a variety of red grape that is cultivated on 65 thousand hectares only in Spain. Periodic maintenance of the crop must be carried out through winter pruning from December to March. The pruning biomass is burned or crushed and incorporated into the soil, producing environmental contamination and disease transmission. The objective of this work was to use the biomass from vineyard residues in the production of binderless particleboards without using any adhesives, thereby obtaining an ecological product that would benefit the environment. In the manufacturing process, the press temperature (130 °C) and pressure (2.6 MPa) were fixed, varying the particle size (<0.25, 0.25 to 1.00, and 1.00 to 2.00), and the pressing time (15, 30, and 45 min). The results showed that by using particles smaller than 0.25 mm and applying 45 min in the hot press, panels were manufactured that are suitable for general use in a dry environment and for the manufacture of furniture according to European standards.

Abstract:
Essential oils (EOs) are natural and economically valuable aromatic compounds obtained from a variety of crops and trees, including forest trees, which have different therapeutic and biological activities. This project aims to assess the impact of different residual forest biomass pretreatments on the yield and the properties of EOs, including their antibacterial and antioxidant characteristics. Forest biomass from black spruce (BS, Picea mariana Mill.), balsam fir (BF, Abies balsamea), and jack pine (JP, Pinus banksiana Lamb.) was processed mechanically by (i) shredding, (ii) grinding, (iii) pelletizing, and (iv) bundling. EOs were then extracted by hydro- and steam distillation. The densification into bundles was found to improve EOs yield compared to the other residual forest biomass pretreatments. For example, the yield of bundled BF was improved by 68%, 83%, and 93% compared to shredded, ground, and granulated biomass, respectively. The highest yield was obtained when densification into bundles was combined with extraction through hydrodistillation. As for EOs’ chemical composition, JP had the highest polyphenol content and consequently the greatest antioxidant activity. EOs derived from BS inhibited the growth of Gram-positive Staphylococcus aureus bacteria and Gram-negative Salmonella typhimurium and Escherichia coli bacteria. The densification of forest biomass into bundles did not affect the antioxidant capacity or the antibacterial activity of EOs, thereby preserving both properties. Thus, the pretreatment of forest biomass residue could have an impact on the volume and the transport costs and therefore improve the bioproducts market and the bioeconomy in Canada.

Full text
Abstract:
With an apparent abundance of idled and under-utilized agricultural land in Northern Ontario, there is interest in the ability of short-rotation forests to supply bioenergy and other possible bioproducts. Once established, Short Rotation Coppice (SRC) plantations can be harvested on (roughly) three-year cutting cycles until about age 22. Purpose-grown plantations such as these could be used as stand-alone sources of fibre or used in conjunction with sources such as natural forests or woody residues. Using a recently developed land cover model we found that approximately 405 500 ha of agricultural-type land exists across Northern Ontario. Numerous scenarios were developed to calculate SRC profitability on these areas. The analyses are intended to reflect a broad range of expectations on physical yields and prices, including management costs. Although SRC involves a considerable up-front investment, our simulations suggest a significant amount of land could have a break-even biomass price of $85/oven-dried tonnes (ODT) (+/- $5/ODT) at farm gate. This farm gate biomass price represents roughly current traditional biomass prices paid. Thus SRC would need to produce biomass at a comparable cost to be a competitive option. A number of technological and price changes could increase the attractiveness of SRC systems in Northern Ontario, including decreases in establishment and management costs (while maintaining yield expectations) and improved cultivars offering increased yields.

Abstract:
Technological development has enabled the production of new value-added products from lignocellulosic residues such as lignin. This has allowed the forest industry to diversify its product portfolio and maximize the economic returns from feedstock, while simultaneously working towards sustainable alternatives to petroleum-based products. Although previous research has explored industrial-scale production opportunities, many challenges persist, including the cost of woody biomass and its supply chain reliability. While numerous studies have addressed these issues, their emphasis has traditionally been on bioenergy, with little focus on biochemical, biomaterials, and bioproducts. This review seeks to address this gap through a systematic study of the work recently reported by researchers. A lot of work has been published from United States and Canada with an emphasis on bioenergy production (84.8%), 4.6% of the work is focused on biomass to materials and chemicals, and 10.6% addressed both. Between 2012 and 2015, the majority of published research focused on biomass to materials and chemicals and both biomass to energy and biomass to materials and chemicals. This fact highlights recent interests in diversified biorefinery portfolios. However, further work concerning forest biomass supply chain optimization and new high-value bio-based materials and chemicals is necessary.

Abstract:
Despite the negative effects of fossil fuels on the environment, these remain as the primary contributors to the energy sector. In order to mitigate global warming risks, many countries aim at reducing greenhouse gas emissions. Bioenergy crops are being used as a substitute for fossil fuels and short rotation forestry is a prime example. In order to examine the sustainability of energy crops for fuel, typical European short rotation forestry (SRF) biomass, willow (Salix spp.) and poplar (Populus spp.) are examined and compared to rapeseed (Brassica napus L.) in respect to various aspects of soil respiration and combustion heat obtained from the extracted products per hectare. Various approaches are used to look at an As-contaminated site not only in the field but also in a soil-column experiment that examines the fate of trace elements in SRF soils, and in an analysis using MICMAC to describe the driving factors for SRF crop production. Based on the cause-effect chain, the impacts of land-use change and occupation on ecosystem quality are assessed when land-use is changed from degraded land (grassland) to willow and poplar SRF. A manual opaque dynamic closed chamber system (SEMACH-FG) was utilized to measure CO2 emissions at a willow/poplar short rotation forest in Krummenhennersdorf, Germany during the years 2013 and 2014, and at a rapeseed site in 2014. Short rotation forest soils showed higher CO2 emission rates during the growing season than the dormant season – with a CO2 release of 5.62±1.81 m-2 s-1 for willows and 5.08±1.37 µmol CO2 m-2 s-1 for poplars in the growing season. However, during the dormant season the soil sites with willow emitted 2.54±0.81 µmol CO2 m-2 s-1 and with poplar 2.07±0.56 µmol CO2 m-2 s-1. The highest emission rates for the studied plantations were observed in July for both years 2013 and 2014, during which the highest air and soil temperatures were recorded. Correlations between soil emission of CO2 and some meteorological parameters and leaf characteristics were investigated for the years 2013 and 2014. For example, for the willow clone (Jorr) and poplar clone (Max 3), high correlations were found for each between their soil emission of CO2 and both soil temperature and moisture content. Fitted models can explain about 77 and 75% of the results for Jorr and Max 3 clones, respectively. Moreover, a model of leaf area (LA) can explain about 68.6% of soil CO2 emission for H275. Estimated models can be used as a gap-filling method, when field data is not available. The ratio between soil respiration and the combustion heat calculated from the extracted products per hectare was evaluated and compared for the study’s willow, poplar and rapeseed crops. The results show that poplar and willow SRF has a very low ratio of 183 kg CO2 GJ 1 compared to rapeseed, 738 kg CO2 GJ 1. The soil-column experiment showed that by continuing the SRF plantation at the As-contaminated site, remediation would need only about 3% of the time needed if the site was left as a fallow field. In order to understand the complex willow and poplar short rotation forestry production system, 50 key variables were identified and prioritized to describe the system as a step to enhance the success of such potentially sustainable projects. The MICMAC approach was used in order to find the direct and the indirect relationships between those parameters and to classify them into different clusters depending on their driving force and interdependency. From this, it can be summarized that in order to enhance the success of a SRF system, decision makers should be focussing on: ensuring a developed wood-fuel market, increasing farmers’ experience/training, improving subsidy regulations and recommending a proper harvesting year cycle. Finally, the impacts of land-use change and occupation on the ecosystem quality were assessed. Results show that establishing SRF plantations on degraded lands improved the ecosystem structural quality (ESQ) by about 43% and ecosystem functional quality (EFQ) by about 12%. Based on overall results, poplar and willow SRF biomass can be recommended as renewable and sustainable sources for bioenergy.

Abstract:
A busca por segurança energética tem feito com que a maioria dos países empenhe-se na busca por fontes alternativas de energia, procurando mitigar problemas econômicos, sociais e ambientais. Espera-se que a biomassa, disponível de forma geograficamente dispersa, venha a tornar-se um dos principais recursos renováveis na produção de alimentos, materiais, produtos químicos, combustíveis e energia. Nesse cenário, o desenvolvimento de biorrefinarias representa a chave para uma produção integrada, combinando rotas de conversões químicas, bioquímicas e termoquímicas, no processamento da biomassa, visando à utilização otimizada dos recursos disponíveis. As biorrefinarias com estruturas descentralizadas são uma alternativa à centralização de produções em grandes plantas industriais e à monocultura, pois utilizam biomassas disponíveis regionalmente, integram sistemas de produção, potencializando os recursos locais, reduzem custos com logística e impactos ambientais, além de melhorarem a distribuição da renda. O presente trabalho apresenta uma revisão da disponibilidade de biomassa no Brasil e no mundo, com especial interesse no aproveitamento de microalgas e resíduos orgânicos, dos principais produtos de interesse e conceitos de biorrefinarias existentes. O objetivo é discutir qual é o conceito que melhor se adapta às necessidades do cenário brasileiro, bem como propor um modelo com estrutura descentralizada em duas ou três etapas, visando à otimização de um processamento sustentável de biomassa para obtenção de vários produtos comerciáveis e energia, além de delinear diretrizes para investimentos na área. É apresentada uma metodologia para a tomada de decisões na concepção e análise de viabilidade do projeto conceitual de uma biorrefinaria, considerando-se também as restrições de ordem ecológica, econômica e tecnológica. Como estudo de caso, é proposta uma biorrefinaria a partir de microalgas. A escolha por microalgas como matéria-prima é baseada nas vantagens que sua utilização apresenta frente à de outras biomassas, dentre elas cita-se a capacidade de produção rápida e durante todo o ano, a captura do CO2 necessário ao seu crescimento, a necessidade de menos água do que plantas terrestres, são cultiváveis em água salobra e terras não aráveis, apresentam elevado teor de óleo, seus nutrientes podem ser obtidos a partir de águas residuais, sua composição bioquímica pode ser modulada por diferentes condições de crescimento e são capazes de produção fotobiológica de bio-hidrogênio. Das alternativas de rotas possíveis para seu processamento, são apresentadas duas que apontam como sendo as mais promissoras: o uso da microalga como substrato de algum outro microorganismo, visando à obtenção de compostos com maior valor agregado, tais como biopolímeros, e o uso do processo de pirólise rápida para obtenção de bio-óleo, que deve ser processado posteriormente, visando à especificação em biocombustível. As vantagens da otimização do cultivo, colheita, rotas viáveis de processamento e a análise do potencial econômico desse modelo, indicam uma excelente oportunidade para obtenção de um espectro de produtos de alto valor agregado e energia e um grande potencial de aplicação.
The search for energy security has been doing with that most of the countries strive to seek alternative sources of energy that allows mitigating economic, social and environmental problems. It is expected that biomass, available on a geographically dispersed way, will become one of the major renewable resources for food, materials, chemicals, fuels and energy production. Additionally, the development of biorefineries represents the key to an integrated production, combining chemical, biochemical and thermochemical conversion routes for biomass processing, aiming the optimized use of available resources. Biorefineries with decentralized structure are an alternative to the centralization of production in large industrial plants and to the monoculture because it uses biomass regionally available, integrates production systems potentiating local resources, reduces logistics costs and environmental impacts, as well as improves income distribution. This work presents a review of: i) biomass availability in Brazil and in the world, focus on the use of microalgae and organic wastes; ii) the main products of interest; and; iii) concepts of existing biorefineries. The objective is to discuss which one is the concept that better fits the needs of the Brazilian scenario and propose a new model with decentralized structure in two or three stages, seeking to an optimized and sustainable biomass processing to obtain various marketable products and energy, and delineate guidelines for investment in the area. It is presented a methodology for making the conceptions decisions and feasibility analysis of the conceptual design of a generic refinery, considering also the ecological, economic and technological constraints. As a case study, it is proposed a biorefinery from microalgae. The choice of microalgae as a raw material is based on the advantages that their use offers over the others biomasses. Among the advantages it can be cited the ability for rapid production and during all the year, the capture of CO2 for its growth, the need for less water than land plants, they can be cultivated in brackish water and non-arable land, have a high oil content, nutrients can be obtained from waste water, their biochemical composition can be modulated by different growth conditions and are capable of producing photobiology bio-hydrogen. Of the possible alternative routes for microalgae processing, are presented two as the most promising: the use of microalgae as a substrate for some other microorganism in order to obtain compounds with high added value, biopolymers as an example, and use the process of fast pyrolysis for obtaining bio-oil, which will be processed later in order to specify biofuels. The advantages of the cultivation optimization, harvesting, processing viable routes and analyzing the economic potential of this model indicate an excellent opportunity to obtain a spectrum of value-added products and energy and its great potential for application.

Abstract:
The goal of this research study was to contribute to a better understanding of the challenges and opportunities of developing a woody biomass industry that includes non-industrial private forest (NIPF) landowners. Surveys were administered to 475 forest landowners before and after a forestry extension education program on emerging woody biomass markets in ten counties across North Carolina. We predicted that landowners would have low knowledge levels of woody biomass but, as a result of participating in the training, would increase knowledge, have more positive attitudes, and develop aspirations to harvest woody biomass on their land. Results, based on 395 returned surveys, confirmed these hypotheses, thus strengthening the perception of the importance of woody biomass educational programs as a component of renewable energy adoption plans. However, while the majority of landowners reported that the information gained was beneficial, we found that landowners would like more specific information before committing to participate in emerging woody biomass markets. Outreach to minority and traditionally underserved landowners also requires considerable development. If Extension professionals do not make a conscious effort to reach out to these populations they will be effectively excluded from this woody biomass market opportunity. These findings will assist Extension agents and other adult educators, policy makers, and energy or timber industry professionals to make informed decisions when developing policies and programs concentrated on woody biomass harvesting for energy.

Abstract:
Forests in boreal and temperate forest-ecosystems have an important function since they sequester atmospheric carbon by uptake of carbon-dioxide in photosynthesis, and transfer and store carbon in the forest ecosystem. Forest material can be used for bio-fuel purposes and substitute fossil fuels, and supply wood products, which can replace carbon- and energy-intensive materials. Therefore it is vital to consider the role of forests regarding today´s aim to mitigate climate change. This thesis assess (i) how climate change affects future forest carbon balance, (ii) the importance of different strategies for forest management systems, and biomass production for the carbon balance, (iii) how the use of forest production affect the total carbon balance in a lifecycle perspective, and (iv) how the Swedish carbon balance is affected from the standpoint of both the actual use of forest raw material within Sweden and what Swedish forestry exports. The analysis was made mainly in a long-term perspective (60-300 year) to illustrate the importance of temporal and also the spatial perspective, as the analysis includes stand level, landscape level, and national level. In this thesis, forestry was considered a system. All activities, from forest regeneration to end use of forest products, were entities of this system. In the evaluation, made from a systems perspective, we used life-cycle analysis to estimate carbon stock in different system flows. Different forest management systems and forest production were integrated in the analyses. Different forest management scenarios were designed for the Swedish forest management in combination with the effect of future climate change; (i) intensive forest practice aiming at increased growth, (ii) increased forest set-aside areas, changes in forest management systems for biomass production, and (iii) how the use of forest production affect the total carbon balance (construction material, bioenergy and other domestic use). The results showed that future climate changes and intensive forest management with increased production could increase the biomass production and the potential use of forest raw material. This has a positive effect on carbon storage for the forest carbon stock, litter production and carbon storage in the ground etc. and help mitigating carbon-dioxide. Increased forest set-aside areas can increase the short-term carbon stock in forest ecosystems, but will reduce the total long-term carbon balance. The net carbon balance for clear-cut forestry did not differ significantly from continuous-cover forestry, but was rather a question of level of growth. Most important, in the long term, was according to our analysis, how forest raw material is used. Present Swedish forestry and use of forest raw material, both within Sweden and abroad, reduce carbon-dioxide emissions and mitigate climate change. The positive effect for the total carbon balance and climate benefit take place mostly abroad, due to the Swedish high level of export of wood products and the higher substitution effects achieved outside Swedish borders. One strategy is to increase production, harvest and change the use of Swedish forest raw material to replace more carbon intensive material, which can contribute to significant emission reduction. Carbon-dioxide mitigation, as a result of present Swedish forestry, was shown to be almost of the same level as the total yearly emission of greenhouse gases. The total carbon benefit would increase if the biomass production and felling increased and if Swedish wood products replaced carbon intensive materials.This thesis shows also that, by changing forest management, increase the growth and the use of forest raw material and export of forest material we can contribute to even larger climate benefits. In a long-term perspective, the substitution effects and replacement of carbon- and energy-intensive materials are of greater significance than carbon storage effects in forests. A more production oriented forestry needs to make balances and increase the prerequisite for biological diversity, improve recreation possibilities, and protect sensitive land areas and watersheds.Climate benefits, from Swedish forestry, are highly dependent on policy decision-making and how that can steer the direction for the Swedish forestry.

Abstract:

There has been an unusual shift in timberland ownerships in the United States over the past few decades, in which mostly Forest Product Companies have divested properties to institutional owners, like Timber Investment Management Organizations and Real Estate Investment Trusts. Northeast region of the country has been influenced by this trend. Studies have suggested changes in harvesting, silviculture, and conservation efforts under new ownerships may alter forest structure and resiliency. However, there is little documentation on the spatial pattern of such ownership change and its effect on forest dynamics. This dissertation tries to address some of these knowledge gaps by applying a variety of spatial and statistical analyses to Forest Inventory and Analysis (FIA) data from 2003 to 2012. In Chapter 2, I assessed spatial pattern of change in timberland ownerships and linked these incidences with socio-ecological variables. Largest observed shift was from industrial to institutional ownership, a net increase of only 1% in institutional timberlands. However, there was a significant clustering pattern, and clusters were significantly related to forest type, distance from urban center and distance from road. In Chapter 3, I explored changes in aboveground biomass (?AGB) among different ownerships, harvesting, and forest types, and other selected factors. Overall, a positive ?AGB (671 lb/ac/yr) was observed, with Non Industrial Private Forest (NIPF) timberlands having higher growth than industrial and institutional timberlands. Among forests, Elm-Ash-Cottonwood had the best growth, and among harvesting regimes, plots harvested before first measurement had highest growth. Ownership, harvest, disturbance, silvicultural treatment, forest type, stand age, site index, and precipitation were significantly related to ΔAGB. In Chapter 4, I compared three indices used to characterize similarity between overstory-understory tree species composition and assessed potential future change in forest composition. Ownership, forest types, precipitation, stand age, site index, stand origin, slope, elevation, proximity to road and urban centers all contributed to explaining variation in change in similarity indices. Among ownership categories, industrial and institutional ownerships had greater dissimilarity over time, in contrast to other ownerships. The final chapter discusses some potential implications of these results to northern forest structure, resiliency and sustainable production.

Abstract:

Biomass district heating (BDH) has the potential to stimulate rural economies in the Tug Hill region of New York State by establishing a local industry and providing lower cost heat compared to the local alternative, #2 fuel oil. However, the competitiveness and economic impact of BDH networks in rural villages is largely unknown. This study proposes a methodology to provide initial assessments of the feasibility of BDH in rural communities. BDH would deliver heat below the cost of the local alternative in eight of the ten study villages examined. Capital costs comprised over 80% of the project costs, illuminating the importance of reaching a sufficient heat density; however, specific building heat was a stronger determinant of a village's feasibility. An input-output analysis determined that BDH would generate $18.6 million in output and create 143 jobs throughout the three county region, a significant impact if concentrated around the study villages.

Linnig, William A. III. "IS DENSIFIED BIOMASS FUEL FROM AGRO-FORESTRY WASTE A SUSTAINABLE ENERGY OPTION?" UKnowledge, 2012. http://uknowledge.uky.edu/me_etds/7.

Full text
Abstract:
Raw biomass material is bulky, high in void fraction, and very low in transportation efficiency. Furthermore, biomass dissipates quickly in harsh environments of high heat furnaces because of its relatively low calorific value (BTU/lb) and has grinding or size degradation properties highly dissimilar from commonly-used fossil fuels like coal. Therefore, the development of transformational technologies are necessary to convert raw biomass into high-value and useful products of high hardness and calorific value without requiring excessive process energy. This thesis investigates the sustainability of densified biomass fuels. In addition, a procedure that converts raw biomass from agro/forest industry waste into a fuel source known as semi-carbonized densified biomass (SCDB) is shown to have the necessary performance qualities that are conducive to applications involving the harsh conditions of high heat furnaces. The SCDB is produced at temperatures between 115-230°C and pressures between 8-25 MPa. The raw biomass is transformed into a densified fuel source with maximum compressive strengths between 60-200 MPa and calorific values between 18-23 MJ/kg, which are essential to operating in high heat furnace environments. The procedural steps and equipment used to manufacture this densified fuel source are outlined in detail along with experimental results and discussions of initial testing.

Abstract:
Abstract Biomass-based products (bioproducts) have been introduced as a means to address food-energy-water nexus challenges. However, the existing approaches have not been integrated to convert biomass into market-competitive bioproducts (e.g., biochar and bio-oil). Pretreatment and conversion processes represent the most substantial portion of the total bioproduct cost. This study proposes a portable conversion process for high-quality biochar and bio-oil production, using mixed reactors and advanced cyber-physical infrastructures to promote cross-cutting technological and commercialization opportunities. The proposed portable process converts biomass to bioproducts near the collection sites, which can address collection, staging, and logistics challenges. The fundamental novelty of this study lies in utilizing cyber-physical technologies for advancing pre-/post-conversion processes and crossing the boundaries to meet the market needs. A case study for biochar production from various biomass feedstocks is used to demonstrate and verify the application of the conversion process and the cyber-based advances. The results indicate that the integrated cyber-physical conversion pathway can increase process yield and quality. It is also found that biomass properties and conversion process configurations play a crucial role in determining the process yield and biochar quality in terms of the physical-chemical structure.
