Abstract:
Sorghum stem bagasse waste is one of the materials with high cellulose content. It can be utilized in glucose production through enzymatic hydrolysis of cellulose by Trichoderma viride. This study aims to determine sorghum stem bagasse’s potential in producing glucose, assessing the time and concentration of sorghum stem bagasse in the hydrolysis process to produce glucose optimally and following SNI. Hydrolysis was carried out using a concentration of 5%, 8%, and 11% sorghum stem bagasse for 10, 15, and 20 days. The results showed that sorghum stem bagasse waste could produce glucose with an average glucose yield of 10.09% to 24.40 %. There is a tendency that increasing substrate concentration and hydrolysis time will increase the yield of liquid glucose. The treatment of 5% concentration of sorghum stem bagasse with a long hydrolysis time of 10 days can produce the highest liquid glucose, namely 24.40% with total dissolved solids of 7.40% Brix, the ash content of 0.26%, but 47.54% water content has not met SNI standards.Â

Abstract:
Utilization of sugarcane bagasses for butanol, ethanol and acetone production was studied by acid hydrolysis and bacterial fermentation. Glucose, xylose and arabinose contents of sugarcane bagasse hydrolyzed in 5% (v/v) sulfuric acid solution were investigated in respective range of 5 to 60 min. Results showed glucose and xylose released during hydrolysis at 121 C and long treatment time of 60 minutes had high concentrations of 18.7 and 19.8 g/l, respectively. The sugarcane bagasse hydrolysate was then used for butanol, ethanol and acetone production by anaerobic fermentation using C.butyricum, C. sporogenes, C.beijerinckii and C.acetobutylicum. The maximum production based on solvent yield was 4.7 g/l butanol, 6.3 g/l ethanol and 9.7 g/l acetone obtained from fermentation of sugarcane bagasse hydrolysate using C. beijerinckii for 48 hours in the presence of 0.5% (w/v) sugarcane bagasse.

Abstract:
HighlightsJuice extraction resulted in a decrease in the nutritive value of the bagasse as compared with the initial biomass.Silages made from the second pressing bagasse were well conserved.Sweet sorghum silage has a better nutritive value than sweet pearl millet.Abstract. Pressing the biomass of sweet sorghum and sweet pearl millet in-field is one of the suggested options for bioethanol production. The extracted juice can be delivered to an ethanol plant, and the bagasse (pressing residue) can be used for ruminant feeding. Efficient carbohydrate extraction is highly important for good ethanol yield. However, enough carbohydrates must remain in the bagasse for its adequate conservation as silage. In this study, the ensilability and the chemical composition of the second pressing bagasse of sweet sorghum and sweet pearl millet were investigated. The bagasse was obtained following a second pressing of the first pressing bagasse after its impregnation with water based on three water:bagasse ratios (0.5, 1, and 1.5). Results indicated that water:bagasse ratio did not affect water-soluble carbohydrate (WSC) extraction for both crops. The second pressing bagasse of sweet sorghum and sweet pearl millet contained 80.5 ±4.6 and 60 ±4.6 g of WSC kg-1 dry matter (DM), respectively. The second pressing bagasse of both crops had reduced nutritive value compared to the initial biomass, i.e., higher neutral detergent fiber (NDF) and acid detergent fiber (ADF) concentrations along with lower non-structural carbohydrate (NSC) concentration, in vitro true digestibility of DM (IVTD), and in vitro NDF digestibility (NDFd). The second pressing bagasses of both crops also showed good ensilability, but sweet sorghum bagasse silages were of better nutritive value than sweet pearl millet bagasse silages (ADF = 446.2 ±3.7 vs. 463.2 ±3.7 g kg-1 DM, IVTD = 813.8 ±3.4 vs. 708.8 ±6.8 g kg-1 DM, and NDFd = 741.8 ±4.8 vs. 596.2 ±8.5 g kg-1 NDF, respectively). The water:bagasse ratio used for bagasse impregnation before the second pressing only affected the NDF concentration of silages, as a higher NDF concentration was obtained with a water:bagasse ratio of 1.5. Sweet sorghum and sweet pearl millet can be considered dual-purpose crops; the extracted juice can be fermented into ethanol, and the second pressing bagasse can be used to make good-quality silage. Keywords: Bagasse impregnation, Nutritive value, Silage, Sweet pearl millet, Sweet sorghum, Water-soluble carbohydrates.

Abstract:
The resources and reserves of oil which is a non renewable energy are very limited, while the oil consumption is increasing continuously. It is necessary to look for alternative energy. Etanol, a liquid energy, is a renewable alternative energy. Glucose can be used as raw material for etanol production. Glucose can be obtained by enzymatic hydrolysis of bagasse which is a solid waste of sugar canefactory. The objective of this research was to get the optimum condition of etanol production using bagasse as raw material. The experimental research consisted of 2 steps. First step : enzymatic hydrolysis of bagasse with chemical pretreatment process, and the second step was fermentation process using Zymomonas mobilis bacteria. Variables of thefirst step were the NaOH concentration (5%, 7% and 9%) as a pretreatment agent, and cellulase enzyme used (30, 40 and 50 cellulase enzyme units/gram bagasse). For the second step, the variables were glucose concentration (I2.5%, 15%, 20%, 22.5%, and 25%) and the fermentation time (20, 24, 28, 32, 36, 40 and 48 hours). The experiment showed that the best result of the enzymatic hydrolysis could be obtained by NaOH 7% as chemical pretreatment agent and using 50 units of cellulase enzyme/gram bagasse. The cellulose conversion of bagasse was 87% within 42 hours period time. The highest etanol concentration of the fermentation process was 9.238% (weight %) and the yield was 0.4912 grams etanol/gram glucose. It was reached by using 22.5% glucose during 48 hours fermentation time.Keywords: etanol; fermentation; Zymomonas mobilis; glucose; hydrolysis; cellulase enzyme; pretreatment;bagasse AbstrakCadangan minyak bumi yang merupakan non renewable energy (energi tak terbarukan) sangat terbatas, sedang konsumsinya terus meningkat.

In this paper, bagasse (de-pithed bagasse) and bagasse pith were treated respectively, the process of hemicelluloses extraction was optimized, and some parameters which may affect the hemicelluloses yield were discussed, such as alkali charge, temperature and time of extraction. The results showed that the hemicelluloses yield of bagasse was obviously affected by the alkali charge and temperature of extraction increasing at the same liquid-to-solid ratio and time, and the maximum reached 18.47% (base on o.d.) . To bagasse pith, it could obtain hemicelluloses of 15.37% by the same treatment with bagasse. Therefore, both bagasse and bagasse pith were the good materials for hemicelluloses extraction.

Abstract:
In recent years, partial replacement of cement with bagasse ash has been given attention for construction application due to its pozzolanic characteristics. Sugarcane bagasse ash and fine bagasse particles are abundant byproducts of the sugar industries and are disposed of in landfills. Our study presents the effect of burning bagasse at different temperatures (300 °C and 600 °C) on the compressive strength and physical properties of bagasse ash-blended mortars. Experimental results have revealed that bagasse produced more amorphous silica with very low carbon contents when it was burned at 600 °C/2 h. The compressive strength of mortar was improved when 5% bagasse ash replaced ordinary portland cement (OPC) at early curing ages. The addition of 10% bagasse ash cement also increased the compressive strength of mortars at 14 and 28 days of curing. However, none of the bagasse ash-blended portland pozzolana cement (PPC) mortars have shown improvement on compressive strength with the addition of bagasse ash. Characterization of bagasse ash was done using XRD, DTA-TGA, SEM, and atomic absorption spectrometry. Moreover, durability of mortars was checked by measuring water absorption and apparent porosity for bagasse ash-blended mortars.

Abstract:
The sugar cane industry in Brazil is expanding, leading to great interest in using the leftover bagasse for other uses, beyond burning it for its energy. A thorough physical and chemical characterization of bagasse, particularly regarding its lignin structure, is relevant for a more rational utilization of the bagasse in the production of printing and writing pulp grades, dissolving pulp, ethanol, and power. The main goals of this study were characterizing the chemical (pith and fibers fractions) and morphologic (fibers fraction) properties of the sugar cane bagasse and the structure of the depithed bagasse lignin by two-dimensional nuclear magnetic resonance spectroscopy. Industrial whole bagasse was separated into two fractions: pith and depithed bagasse. The pith was only characterized chemically. The depithed bagasse was chemically and morphologically characterized. The cellulose, hemicelluloses, and lignin contents of the two materials varied significantly. The lignin composition of the depithed bagasse showed very high contents of phenolic cinnamic acids (PCAs). The depithed bagasse lignin presented fractions with different structural monomer distributions. The morphological analyses of the depithed bagasse indicated a short fiber material, similar to hardwoods.

Abstract:
The sugar industry is an ideal sector for electricity cogeneration due to a large amount of burnable bagasse produce as a by-product. Bagasse produced in the sugar industry always consists of moisture affecting the efficiency of a boiler in the cogeneration plant. In our case study, a cogeneration plant run by bagasse burning found with bagasse moisture problem and suffocating with low power generation for the last few years. The boiler efficiency per tonne of bagasse is currently lower than optimal due to the substantial percentage of water present in the bagasse. A bagasse dryer design for this industry can improve the efficiency of a boiler as well as the cogeneration plant. In this paper, a pneumatic bagasse drying system is proposed to reduce the moisture content of bagasse from 48% to 30%. This work provides a full analysis of bagasse dryer design parameters, including specifications for dryer system components, such as feeders, fan, drying tube, and cyclone. The total bagasse drying system proposed is expected to be fitted within a 6 × 6 × 25 m space to dry 60 tph of bagasse, reducing the moisture content from 48% to 30%, in full compliance with all relevant Australian and company standards.

ENGLISH ABSTRACT: The world’s depleting fossil fuels and increasing greenhouse gas emissions have given rise to much research into renewable and cleaner energy. Biomass is unique in providing the only renewable source of fixed carbon. Agricultural residues such as Sugarcane Bagasse (SB) are feedstocks for ‘second generation fuels’ which means they do not compete with production of food crops. In South Africa approximately 6 million tons of raw SB is produced annually, most of which is combusted onsite for steam generation. In light of the current interest in bio-fuels and the poor utilization of SB as energy product in the sugar industry, alternative energy recovery processes should be investigated. This study looks into the thermochemical upgrading of SB by means of pyrolysis. Biomass pyrolysis is defined as the thermo-chemical decomposition of organic materials in the absence of oxygen or other reactants. Slow Pyrolysis (SP), Vacuum Pyrolysis (VP), and Fast Pyrolysis (FP) are studied in this thesis. Varying amounts of char and bio-oil are produced by the different processes, which both provide advantages to the sugar industry. Char can be combusted or gasified as an energy-dense fuel, used as bio-char fertilizer, or upgraded to activated carbon. High quality bio-oil can be combusted or gasified as a liquid energy-dense fuel, can be used as a chemical feedstock, and shows potential for upgrading to transport fuel quality. FP is the most modern of the pyrolysis technologies and is focused on oil production. In order to investigate this process a 1 kg/h FP unit was designed, constructed and commissioned. The new unit was tested and compared to two different FP processes at Forschungszentrum Karlsruhe (FZK) in Germany. As a means of investigating the devolatilization behaviour of SB a Thermogravimetric Analysis (TGA) study was conducted. To investigate the quality of products that can be obtained an experimental study was done on SP, VP, and FP. Three distinct mass loss stages were identified from TGA. The first stage, 25 to 110°C, is due to evaporation of moisture. Pyrolitic devolatilization was shown to start at 230°C. The final stage occurs at temperatures above 370°C and is associated with the cracking of heavier bonds and char formation. The optimal decomposition temperatures for hemicellulose and cellulose were identified as 290°C and 345°C, respectively. Lignin was found to decompose over the entire temperature range without a distinct peak. These results were confirmed by a previous study on TGA of bagasse. SP and VP of bagasse were studied in the same reactor to allow for accurate comparison. Both these processes were conducted at low heating rates (20°C/min) and were therefore focused on char production. Slow pyrolysis produced the highest char yield, and char calorific value. Vacuum pyrolysis produced the highest BET surface area chars (>300 m2/g) and bio-oil that contained significantly less water compared to SP bio-oil. The short vapour residence time in the VP process improved the quality of liquids. The mechanism for pore formation is improved at low pressure, thereby producing higher surface area chars. A trade-off exists between the yield of char and the quality thereof. FP at Stellenbosch University produced liquid yields up to 65 ± 3 wt% at the established optimal temperature of 500°C. The properties of the bio-oil from the newly designed unit compared well to bio-oil from the units at FZK. The char properties showed some variation for the different FP processes. At the optimal FP conditions 20 wt% extra bio-oil is produced compared to SP and VP. The FP bio-oil contained 20 wt% water and the calorific value was estimated at 18 ± 1 MJ/kg. The energy per volume of FP bio-oil was estimated to be at least 11 times more than dry SB. FP was found to be the most effective process for producing a single product with over 60% of the original biomass energy. The optimal productions of either high quality bio-oil or high surface area char were found to be application dependent.
AFRIKAANSE OPSOMMING: As gevolg van die uitputting van fossielbrandstofreserwes, en die toenemende vrystelling van kweekhuisgasse word daar tans wêreldwyd baie navorsing op hernubare en skoner energie gedoen. Biomassa is uniek as die enigste bron van hernubare vaste koolstof. Landbouafval soos Suikerriet Bagasse (SB) is grondstowwe vir ‘tweede generasie bio-brandstowwe’ wat nie die mark van voedselgewasse direk affekteer nie. In Suid Afrika word jaarliks ongeveer 6 miljoen ton SB geproduseer, waarvan die meeste by die suikermeulens verbrand word om stoom te genereer. Weens die huidige belangstelling in bio-brandstowwe en ondoeltreffende benutting van SB as energieproduk in die suikerindustrie moet alternatiewe energie-onginningsprosesse ondersoek word. Hierdie studie is op die termo-chemiese verwerking van SB deur middel van pirolise gefokus. Biomassa pirolise word gedefinieer as die termo-chemiese afbreking van organiese bio-materiaal in die afwesigheid van suurstof en ander reagense. Stadige Pirolise (SP), Vakuum Pirolise (VP), en Vinnige Pirolise word in hierdie tesis ondersoek. Die drie prosesse produseer veskillende hoeveelhede houtskool en bio-olie wat albei voordele bied vir die suikerindustrie. Houtskool kan as ‘n vaste energie-digte brandstof verbrand of vergas word, as bio-houtskoolkompos gebruik word, of kan verder tot geaktiveerde koolstof geprosesseer word. Hoë kwaliteit bio-olie kan verbrand of vergas word, kan as bron vir chemikalië gebruik word, en toon potensiaal om in die toekoms opgegradeer te kan word tot vervoerbrandstof kwaliteit. Vinnige pirolise is die mees moderne pirolise tegnologie en is op bio-olie produksie gefokus. Om die laasgenoemde proses te toets is ‘n 1 kg/h vinnige pirolise eenheid ontwerp, opgerig en in werking gestel. Die nuwe pirolise eenheid is getoets en vegelyk met twee verskillende vinnige pirolise eenhede by Forschungszentrum Karlsruhe (FZK) in Duitsland. Termo-Gravimetriese Analise (TGA) is gedoen om die ontvlugtigingskenmerke van SB te bestudeer. Eksperimentele werk is verrig om die kwaliteit van produkte van SP, VP, vinnige pirolise te vergelyk. Drie duidelike massaverlies fases van TGA is geïdentifiseer. Die eerste fase (25 – 110°C) is as gevolg van die verdamping van vog. Pirolitiese ontvlugtiging het begin by 230°C. Die finale fase (> 370°C) is met die kraking van swaar verbindings en die vorming van houtskool geassosieer. Die optimale afbrekingstemperatuur vir hemisellulose en sellulose is as 290°C en 345°C, respektiewelik, geïdentifiseer. Daar is gevind dat lignien stadig oor die twede en derde fases afgebreek word sonder ‘n duidelike optimale afbrekingstemperatuur. Die resultate is deur vorige navorsing op TGA van SB bevestig. SP en VP van bagasse is in dieselfde reaktor bestudeer, om ‘n akkurate vergelyking moontlik te maak. Beide prosesse was by lae verhittingstempo’s (20°C/min) ondersoek, wat gevolglik op houtskoolformasie gefokus is. SP het die hoogste houtskoolopbrengs, met die hoogste verbrandingsenergie, geproduseer. VP het hootskool met die hoogste BET oppervlakarea geproduseer, en die bio-olie was weens ‘n dramatiese afname in waterinhoud van beter gehalte. Die meganisme vir die vorming van ‘n poreuse struktuur word deur lae atmosferiese druk verbeter. Daar bestaan ‘n inverse verband tussen die kwantiteit en kwaliteit van die houtskool. Vinnige pirolise by die Universiteit van Stellenbosch het ‘n bio-olie opbrengs van 65 ± 3 massa% by ‘n vooraf vasgestelde optimale temperatuur van 500°C geproduseer. Die eienskappe van bio-olie wat deur die nuwe vinnige pirolise eenheid geproduseer is het goed ooreengestem met die bio-olie afkomstig van FZK se pirolise eenhede. Die houtskool eienskappe van die drie pirolise eenhede het enkele verskille getoon. By optimale toestande vir vinnige pirolise word daar 20 massa% meer bio-olie as by SP en VP geproduseer. Vinnige pirolise bio-olie het ‘n waterinhoud van 20 massa% en ‘n verbrandingswarmte van 18 ± 1 MJ/kg. Daar is gevind dat ten opsigte van droë SB die energie per enheidsvolume van bio-olie ongeveer 11 keer meer is. Vinnige pirolise is die mees doeltreffende proses vir die vervaardiging van ‘n produk wat meer as 60% van die oorspronklike biomassa energie bevat. Daar is gevind dat die optimale hoeveelhede van hoë kwaliteit bio-olie en hoë oppervlakarea houtskool doelafhanklik is.

Abstract:
Sugarcane is a major crop in many countries. It is the most abundant lignocellulosic material in tropical countries such as South Africa. It is one of the plants with the highest bioconversion efficiency. The sugarcane crop is able to efficiently fix solar energy, yielding some 55 tons of dry matter per hectare of land annually. After harvest, the crop produces sugar juice and bagasse. Sugarcane bagasse is a residue that results from the crushing of sugarcane in the sugar industry. It is a renewable feedstock that can be used for power generation and manufacturing cellulosic ethanol. As biomass, sugarcane bagasse holds promise as a fuel source since it can produce more than enough electricity and heat energy to supply the needs of a common sugar factory. However, in the sugarcane industry the bagasse is currently burnt inefficiently in boilers that provide the heating for the industry. This project seeks to investigate the possibility of gasifying sugarcane bagasse as an efficient conversion technology. The investigation is necessary because fuel properties govern the gasifier design and ultimately, the gasification efficiency. Proximate and ultimate analysis of sugarcane bagasse was conducted after which the results were used to conduct a computer simulation of the mass and energy balance during gasification. The kinetic investigation undertaken through the TGA and DTG analyses revealed the activation energy and pre – exponential factor which were obtained by the model – free Kissinger method of kinetic analysis and were found to be 181.51 kJ/mol and 3.1 × 103/min respectively. The heating value of sugarcane bagasse was also measured and found to be 17.8 MJ/kg, which was used in the calculation of the conversion efficiency of the gasification process. Fuel properties, including moisture content and gasifier operating parameters were varied in order to determine optimum gasifier operating conditions that results in maximum conversion efficiency. The highest conversion efficiency was achieved at low moisture content after computer simulation of the gasification process. Moisture content also affected the volume of CO and H2 as the former decreases with increasing moisture content while the latter increases with increasing moisture content, accelerating the water – gas reaction. Scanning electron microscope fitted to an Energy dispersive X – ray spectroscopy was also used in order to view the shape and size distribution as well as determine the elemental composition of sugarcane bagasse. The results obtained established that the fuel properties and gasification conditions affect the conversion efficiency. During computer simulation, it was established that smaller particle size resulted in higher conversion efficiency. The smaller throat diameter also resulted in higher conversion efficiency. The throat angle of 25° also resulted in higher conversion efficiency. The temperature of input air was also found to be one of the major determining factors in terms of conversion efficiency. The dissertation presents the proximate and ultimate analysis results as well as the kinetic analysis results. The SEM/EDX analysis as well as the computer simulation results of the gasification process is also presented. The major contribution of this project was on the investigation of the gasification characteristics of sugarcane bagasse and the utilization of these in the design of a laboratory scale sugarcane bagasse gasifier with enhanced conversion efficiency through computer simulation.

Abstract:
With rapidly increasing interest in a cleaner world environment, biomass com­bustion is becoming a very real alternative energy source to the more traditional coal-fired power stations. Sugar cane bagasse is one such material that is readily available and moreover, has been used as a fuel in the Australian sugar industry for well over thirty years. Today, the most widely utilised bagasse-fired furnace is the 'pneumatic spreader suspension fired furnace'. In this particular design, the solid bagasse particles are blown into the furnace by high velocity air jets, where the majority of the fuel is entrained vertically by a large flow of pre-heated air. This stream is termed 'combustion air' and enters the furnace via a grate spanning the entire furnace floor. Combustion of bagasse in these furnaces has its own special set of problems which appear to be due largely to the high moisture content of the fuel (45 - 55% as fired (wet basis)). Combustion instability in bagasse-fired furnaces is a key issue for operation but is presently not well understood. During periods of instability, there is a con­siderable dulling of the flame, the furnace pressure oscillates, large mounds of wet fuel accumulate on the grate and it becomes impossible to maintain the mill steam requirements. Dixon (1984) describes this as the 'single factor limiting the further development of bagasse suspension firing'. Since the early eighties, the majority of the research into this problem has been on a 'trial and error' basis with only lim­ited success. More recently an in-depth theoretical and computational investigation was undertaken into modelling of bagasse-furnaces (Luo, 1993; Luo and Stanmore, 1994). The work of Luo and Stanmore (1994) and the work of Dixon (1983,1984) provide the starting point for this current research.

The economics of implementing bagasse-based charcoal manufacturing in Haiti was investigated. From these main inputs, three different manufacturing economic scenarios were modeled using a simple, dynamic excel spreadsheet. The first model reflects single family implementation, which reasonable found that a family would be able to make back their start up costs within a month of production. The second model examined sugarcane bagasse charcoal production as an entrepreneurial endeavor for a small community. The third model is similar to the second model, but reflects large-scale factory production. The potential of the second and third models primarily depend on the cost of raw materials and transportation. These models are easily adjusted to reflect market rates and can be generalized to address similar start-up economies.

The present work aimed at the production of lignosulfonate, based in the lignin extracted from sugarcane bagasse-cane for using in phenolic resins. The extraction of lignin was carried out using the acetosolv process, which was optimised with a central composite design 22 to evaluate the effects of reaction time and temperature on the extraction yield, weight-average (M ̅w) and number-average (M ̅n) molecular weights, relative content of total hydroxyl, phenolic hydroxyl and methoxyl groups. The lignins obtained under conditions that maximized the extraction yield and showed better structural and thermal characteristics were sulfonated to obtain the lignosulfonates. The structural and thermal characteristics of the lignins and lignosulfonates were determined by FT-IR, GPC, 1H-NMR and 13C-NMR, DSC and TGA. The results show that the best extraction yield (64.5%) was obtained with 95% (w/w) of acetic acid, the addition of 0.1% HCl, at a temperature of 187 ÂC and reaction time of 40 min. However, with the same concentration of acetic acid and reaction time of 15 min at 187 ÂC, the extraction yield decreased to 55.6% Â 4.5%, without significant reduction. Furthermore, the increase in temperature of 187 ÂC to 205 ÂC was not enough to cause a significant increase in the relative content of hydroxyls and reduction of the relative content of methoxyl. These results show that the most appropriate conditions for adequate extraction of lignin for application in resins are: 95% (w/w) of acetic acid, addition of 0.1% of HCl, temperature of 187 ÂC and reaction time of 15 min. The acetosolv lignins showed p-hidroxifenila units as major constituent, higher thermal stability and higher purity than the commercial Kraft lignin. The glass transition temperature of the Kraft lignins was lower than that of the acetosolv lignin. This is due to the hydrophilic character and the presence of carbohydrates in the Kraft lignin. The lignosulfonates obtained in this study showed structural characteristics suitable for application in phenolic resins, because they showed high reactivity due to the greater presence of p-hidroxifenila units as major constituent, low molecular weights (40234878 g/mol), greater stability and greater purity compared to commercial sodium lignosulfonate. Therefore, lignosulfonates obtained in this work are more suitable for use in phenolic resins than commercial sodium lignosulfonate used for comparison.
O presente trabalho teve por objetivo a produÃÃo de lignossulfonato, a partir da lignina extraÃda do bagaÃo da cana-de-aÃÃcar para aplicaÃÃo em resinas fenÃlicas. Foi realizada a otimizaÃÃo da extraÃÃo da lignina do bagaÃo de cana-de-aÃÃcar utilizando o processo acetosolv. Para tanto, empregou-se um delineamento composto central 22 para analisar os efeitos do tempo de reaÃÃo e da temperatura no rendimento de extraÃÃo, massa molar ponderal mÃdia, massa molar numÃrica mÃdia, e conteÃdo relativo de hidroxilas totais, hidroxilas fenÃlicas e metoxilas. As ligninas obtidas nas condiÃÃes que maximizaram o rendimento de extraÃÃo e que mostraram melhores caracterÃsticas estruturais e tÃrmicas foram sulfonadas para obtenÃÃo dos lignossulfonatos. As caracterÃsticas estruturais e tÃrmicas das ligninas e dos lignossulfonatos foram determinadas por FT-IR, GPC, RMN-1H e 13C, TGA e DSC. Os resultados mostram que o melhor rendimento de extraÃÃo (64,5 % 4,2%) foi obtido com 95% (m/m) de Ãcido acÃtico, adiÃÃo de 0,1% de HCl, a uma temperatura de 187 C e tempo de reaÃÃo de 40 min. No entanto, com a mesma concentraÃÃo de soluÃÃo de Ãcido acÃtico e com tempo de reaÃÃo de 15 min a 187ÂC, o rendimento de extraÃÃo diminuiu para 55,6%  4,5%, nÃo sendo significativa esta reduÃÃo. AlÃm disto, a elevaÃÃo da temperatura de 187ÂC para 205ÂC nÃo foi suficiente para causar um aumento significativo no conteÃdo relativo de hidroxilas e reduÃÃo do conteÃdo relativo de metoxila. Esses resultados mostram que as condiÃÃes mais adequadas para extraÃÃo da lignina a ser aplicada em resinas sÃo: 95% (m/m) de Ãcido acÃtico, adiÃÃo de 0,1% de HCl, temperatura de 187 C e tempo de reaÃÃo de 15 min. As ligninas acetosolv apresentaram unidades p-hidroxifenila como constituinte majoritÃrio, maior estabilidade tÃrmica e maior pureza em relaÃÃo à lignina Kraft comercial. A temperatura de transiÃÃo vÃtrea da lignina Kraft foi menor do que à das ligninas acetosolv, devido à sua caracterÃstica hidrofÃlica e à presenÃa de carboidratos na lignina Kraft. Os lignossulfonatos obtidos no presente trabalho apresentaram caracterÃsticas estruturais adequadas para aplicaÃÃo em resinas fenÃlicas, pois mostraram alta reatividade devido a maior presenÃa de unidades p-hidroxifenila como constituinte majoritÃrio, baixas massas molares (4023 a 4878 g/mol), maior estabilidade e uma maior pureza em relaÃÃo ao lignossulfonato de sÃdio comercial. Portanto, os lignossulfonatos obtidos no presente trabalho sÃo mais adequados para aplicaÃÃo em resinas fenÃlicas do que o lignossulfonato de sÃdio comercial utilizado no presente trabalho.

Abstract:
Sugarcane is considered as the most abundant plant based crop grown in the tropics and part of the temperate climates. Its by-product, sugarcane bagasse, constitutes 30% of the total production. In the past, it was considered as waste material but contemporaries through innovative research projects over the years have found uses for it. Among these projects is soil reinforcement, which provides an alternative application to industrial by-products and natural fibres as a way of reducing their environmental footprints and contributing to sustainable geotechnics. Although bagasse morphological composition contains structural elements ideal for reinforcement and composite materials, it has received little research as a standalone reinforcement material. Because of this, a direct shear test was therefore initiated to establish the usefulness of using sugarcane bagasse as a soil reinforcement material by comparing the extent of shear strength and stiffness response due to its inclusion to unreinforced soil. Three different types of bagasse, fibre, millrun and pith, were added to unreinforced soil in percentage by weight content of 0.3 - 1.7. The bagasse was added to Klipheuwel sand, Cape Flats sand and Kaolin Clay at both dry and moist conditions. In addition, durability studies involving 12 cycles of wetting and drying, and soaking for a period of 14 days were constituted.

Abstract:
This work was stimulated by the fact that supplies of fossil fuels are finite, while there are abundant renewable forms of energy waiting to be tapped. The current fossil fuels store is reviewed before identifying usable forms of renewable energy which could replace or supplement fossil fuels. Bagasse - a solid byproduct in sugarcane milling - is then described in detail as a typical lignocellulosic waste which forms part of a larger class of renewable energy sources called biomass. The chemical and physical characteristics, as well as world-wide regions of production of bagasse are described. The research work therefore concerned itself with investigating various physical methods of conserving renewable energy by improving on the extraction efficiency of such energy from bagasse. The equipment used for carrying out the research work is described in detail in chapter two. The methods employed in carrying out the investigations are similarly described in the same chapter, detailing every step in the investigations, including any precautions which had to be taken. The crude results from the investigations are analysed in detail in chapter three so that fuel combustion, combustion oxygen demand, heat and mass balances for the process are considered. An analysis of the boiler system - the main equipment in the investigations - is also carried out in chapter three so that temperatures, gas flow patterns, particle elutriations and size distributions of the fuel in the system are established. Conclusions of the investigations are then drawn from the analyses of chapter three. As a prelude to the conclusion of the work, an industrial biomass survey carried out in Tanzania is analysed to show that bagasse is not the only lignocellulosic which is produced industrially, and that reasonable financial savings can be obtained from these other lignocellulosics. The work concludes by describing a few areas of related research interest for further investigation.

Abstract:
In the Australian sugar industry, sugar cane is smashed into a straw like material by hammers before being squeezed between large rollers to extract the sugar juice. The straw like material is initially called prepared cane and then bagasse as it passes through successive roller milling units. The sugar cane materials are highly compressible, have high moisture content, are fibrous, and they resemble some peat soils in both appearance and mechanical behaviour. A promising avenue to improve the performance of milling units for increased throughput and juice extraction, and to reduce costs is by modelling of the crushing process. To achieve this, it is believed necessary that milling models should be able to reproduce measured bagasse behaviour. This investigation sought to measure the mechanical (compression, shear, and volume) behaviour of prepared cane and bagasse, to identify limitations in currently used material models, and to progress towards a material model that can predict bagasse behaviour adequately. Tests were carried out using a modified direct shear test equipment and procedure at most of the large range of pressures occurring in the crushing process. The investigation included an assessment of the performance of the direct shear test for measuring bagasse behaviour. The assessment was carried out using finite element modelling. It was shown that prepared cane and bagasse exhibited critical state behaviour similar to that of soils and the magnitudes of material parameters were determined. The measurements were used to identify desirable features for a bagasse material model. It was shown that currently used material models had major limitations for reproducing bagasse behaviour. A model from the soil mechanics literature was modified and shown to achieve improved reproduction while using magnitudes of material parameters that better reflected the measured values. Finally, a typical three roller mill pressure feeder configuration was modelled. The predictions and limitations were assessed by comparison to measured data from a sugar factory.

O bagaço da cana-de-açúcar é uma biomassa vegetal que possui muito potencial de uso devido aos seus três elementos estruturais: celulose, hemicelulose e lignina. Para servir como matéria prima na produção de insumos, o bagaço da cana-de-açúcar precisa passar por um processo de pré-tratamento. Nesse estudo, duas metodologias para o processo de pré-tratamento do bagaço da cana-de-açúcar foram utilizadas: a deslignização via peróxido de hidrogênio (H2O2) e via dióxido de carbono supercrítico (ScCO2). Para o estudo utilizando H2O2, foram desenvolvidos modelos a partir de planejamento experimental, Algoritmos Genéticos (GA, do inglês Genetic Algorithms), Redes Neurais Artificiais (RNA) e Neuro-Fuzzy (ANFIS). As variáveis independentes foram temperatura (25 – 60 graus Celsius), concentração de H2O2 (2 – 15 por cento m/v) e pH (10 – 13), tendo como resposta os teores de lignina residual e oxidada no processo, através de análises de FT-IR e análise pelo método de Klason. Para o estudo utilizando ScCO2 foram construídos modelos a partir de RNA e ANFIS. As variáveis estudadas no processo foram: temperatura (35 – 100 graus Celsius), pressão (75- 300 bar) e teor de etanol na solução de co-solvente (0 – 100 graus Celsius). De modo geral, para os dois processos, os modelos desenvolvidos consideram as variáveis independentes como sendo neurônios na camada de entrada e as variáveis dependentes como sendo neurônios na camada de saída. Todos os modelos neurais e ANFIS desenvolvidos neste trabalho foram avaliados pelo coeficiente de correlação e índices de erro (SSE, MSE e RMSE), além do número de parâmetros. Os resultados mostraram que, dentre estas estratégias estudadas, os modelos neurais se mostraram mais satisfatórios para predição das respostas do pré-tratamento com H2O2, já que se encaixa nos índices de performance estipulados. O mesmo ocorreu no modelo neural para predição do teor de lignina residual no pré-tratamento com ScCO2. Para cada modelo polinomial e neural desenvolvido, foi realizada a investigação das superfícies de respostas e das curvas de contorno. Com esse recurso, foi possível a identificação dos melhores pontos operacionais para os processos, visando a minimização dos teores de lignina residual e oxidada na biomassa.
Sugarcane bagasse is a plant biomass that has a great potential for use due to its three structural elements: cellulose, hemicellulose and lignin. To serve as raw material in the production of other products, sugarcane bagasse needs to undergo a pre-treatment process. In this study, two methodologies for the sugarcane bagasse pretreatment process were used: delignification via hydrogen peroxide (H2O2) and via supercritical carbon dioxide (ScCO2). The models for study the process with H2O2 were developed from experimental planning, Genetic Algorithms (GA), Artificial Neural Networks (ANN) and Neuro-Fuzzy (ANFIS). The independent variables were: temperature (25- 60 degrees Celsius), H2O2 concentration (2 - 15 percent m/v) and pH (10-13). The residual and oxidized lignin contents in the process were evaluated from FT-IR and Klason method analysis. The models for study the process with ScCO2 were developed from RNA and ANFIS. The variables studied in the process were: temperature (35-100 degrees Celsius), pressure (75-300 bar) and ethanol content in the aqueous solution of co-solvent (0-100 percent). In general, for the two processes, the developed models consider the independent variables to be neurons in the input layer and the dependent variables to be neurons in the output layer. All the neural and ANFIS models developed in this study were evaluated by the correlation coefficient and error indexes (SSE, MSE and RMSE), as well as the number of parameters. From the stipulated indices of performance, among the results obtained by the different strategies, the neural models were the most satisfactory for the prediction of pretreatment responses with H2O2. The same occurred in the neural model for prediction of the residual lignin content in the pre-treatment with ScCO2. Response surfaces and the contour curves were investigated for each polynomial and neural model developed. With this resource, it was possible to identify the best operational points for the processes, pointing at minimizing the residual and oxidized lignin contents in the biomass.

In this paper, the distribution of pressure on the bagasse layer in the sugar cane mills and an automatic regulation proposal to increase the efficiency in the extraction of sugar cane juice is approached. An analysis that considers the top shaft-roller as a beam on elastic foundation is carried out. It is possible to determine the pressure distribution on the bagasse layer and the mill bearing reactions. The behavior of the bagasse layer reaction is analyzed for different hydraulic pressures in each side of the mill; being demonstrated, an optimal relationship of pressures to achieve a uniform compression on the bagasse layer. The optimal hydraulic pressure rate is calculated with the help of the outlined method. Finally, once this pressure relation is known, a control strategy is developed for each hydraulic cylinder.

Abstract:
Increasing amounts of agricultural and industrial wastes have prompted researchers to re‑use the wastes as prospective cement replacement materials. Sugarcane bagasse is an agricultural waste that is widely available as a by-product of sugar and ethanol industries. As sugarcane bagasse possesses a high pozzolanic reactivity owing to its high silica content, the potential of extracting silica from sugarcane bagasse ash (SCBA) for cement replacement has to be explored. In the present study, analytical and compressive strength tests were performed on concrete samples to determine the effect of replacing cement with silica extracted from SCBA. Influences of treatment and burning temperature for conversion of sugarcane bagasse to SCBA on the analytical and compressive strength test results were also investigated. Raw and treated bagasse were burned in a muffle furnace for one hour at 600, 700 and 800°C to produce untreated and treated SCBA, respectively. Hydrothermal synthesis was performed on the SCBA for extraction of silica gel. Three types of concrete samples were prepared, which are the control sample that does not contain any cement replacement material and samples that contain 5% silica from untreated and treated SCBA. Compressive strength tests were performed on the samples after seven days of curing. Findings indicate that treatment of the bagasse was essential to produce SCBA of adequate silica content that can improve the compressive strength of the concrete. The increase in compressive strength is at its highest at the burning temperature of 700°C, where a change of +8.05% was achieved.

Abstract:
The catalytic indirectly heated gasification of bagasse was investigated in this study. The quality of the gaseous fuel was assessed using the total energy analysis of the gas, in which both heat content and total yields of the gas produced from the gasification of bagasse are analyzed at temperatures ranging from 700 to 1000°C. Untreated bagasse gasification was used as a baseline for the investigation of the effect of catalysts on the gasification process. The total energy analysis showed a significant improvement of gas quality due to increase of temperature and due to the use of alumina-zinc based catalysts at temperatures below 900°C. The presence of these catalysts in the gasification process affected the quality of the gases formed, mainly by increasing the hydrogen production, reduction of the gas dilution by carbon dioxide and a slightly higher production of carbon monoxide. Above 900°C, temperature dominates the gasification reaction mechanisms causing the catalysts to have little or no significant effect. Thermal cracking of tar is of major importance on the gasification process, as the tar yields reduce from 42.1 to 24.7% of the bagasse original weight with the increase of the gasifier temperature from 700 to 1000°C. However, the solid residue reduced only from 16 to 13.3%. Hence, the increase in the gaseous yields at high temperature appeared to be due to the gasification of tar with some contribution from secondary reactions involving char. The result was the production of a medium heat content gaseous fuel.

Abstract:
Environmentally-friendly, biodegradable, “green” composites were fabricated from starch-based matrix and bagasse (sugar cane waste) fibers. Native corn starch was mixed with glycerin and water, emulsified then added to the bagasse fibers previously prepared and treated by NaOH. The composite was preheated, then pressed for 30 minutes at 5 MPa and 170°C. SEM showed good adhesion between fibers and matrix up to 60wt% fibers. Density measurements showed low porosity for all composite samples up to 60wt% fibers. Both the tensile and flexural strengths increased as the fiber weight fraction increased from 0% to 60%. Water Uptake and thermal degradability tests showed higher stability for composite with increasing fiber content. The results show that the 60wt% bagasse fiber starch-based composite is an eco-friendly and inexpensive candidate for many applications.

Abstract:
PårørendeSenteret har gitt Programområdet pårørendeforskning, ved Universitetet i Stavanger, i oppdrag å utføre en undersøkelse av pårørendesamtalen. Tema i undersøkelse er knyttet til:  Hvem er de pårørende og hvorfor søker de hjelp  Å være pårørende er både en ressurs og en byrde  Samtalen som redskap i profesjonsfag som helse- og omsorgsfagene  Ulike typer teoretisk påvirkning i forhold til pårørendesamtalen Det legges særlig vekt på:  Konstruerte case som eksempler på tilnærmingsmåter i pårørendesamtalen  Tilnærming i prosesser med livsproblemer eksemplifisert med casene.  Har rammebetingelse betydning for samtalen  Skillelinjer mellom samtaler ved Pårørendesenteret og samtaler i helseinstitusjoner  Klientifisering av pårørende De pårørende søker hjelp for egen del fordi de har en nærstående person som er fysisk eller psykisk syk, har en funksjonsnedsettelse eller et rusmisbruk. Eller at de får for lite eller for dårlig informasjon fra hjelpeapparatet eller de ikke vet at det er informasjon og få, eller at hjelpeapparatet viser for liten forståelse for deres situasjon, eller at de ikke finner frem til relevant hjelpeinstans. Pårørendesamtalen ser ut for å ha sitt utspring i generell profesjonsteori fra helse- og sosialfagene, men er påvirket av rådgivningsteori, teori om støttesamtaler, kriseteori, terapeutiske samtaler og annen teoretisk og klinisk bagasje den enkelte har i sin bakgrunn. Brukermedvirkning er sentralt. Profesjonsutøverne møter en stor variasjon av problemer i samtalene, noe som krever gode kommunikasjonsferdigheter og kjennskap til hjelpeapparatet. Det er sentralt for profesjonsutøverne og «skreddersy» tilbudet til den enkelte. Det presenteres seks konstruerte case og tilnærmingsmåter for samtaler. I en analyse og tolkning av tilnærmingsmåtene prøver en å vise hvordan profesjonsteori kan anvendes for å forstå pårørende, men og for å vise at casene representerer flere utfordringer enn det som er vist i det enkelte case. Forskjellene i de organisatoriske forholdene for Pårørendesenteret og helseinstitusjoner og kommuner skaper ulike betingelser for pårørendesamtalen. Det kan se ut som uavhengighet i forhold til hjelpeapparatet er viktig når en skal hjelpe pårørende med og «forhandle frem» ulike tilbud.
