Currently, the ratio of rural electrification by state electricity company (PT. PLN) in Riau is approximately 58.79% which resulted in the slow growth of the rural economy. A total of 277 unit of the electricity generator owned by PT PLN with total installed capacity of 220 thousand KW is only able to meet 19% of electricity in Riau, and 81% of the rest is purchased and acquired from other units. As the region that consists of 61% forestry, Riau has the potency to utilize the biomass energy to meet the electricity in the rural area. Moreover, 43% of forestry area is the industrial production forest that supplied the wood material for two international pulp and paper industry in Riau. Majority planted vegetation to this forest types is Accacia spp and Eucalyptus spp. The leaves litter generated from Accacia and Eucalyptus vegetation reaches 4.4 and 13 tons ha-1 yr-1, respectively. The current utilization of leaves and other litter fall are just left in the area of plantation or burned after harvested. The calorific value of Accacia and Eucalyptus leaves litter are 13.33 MJ/kg and 17.26 MJ/kg, respectively. Utilization of leaves litter from the industrial forestry has a potential to meet the energy needs in Riau by 0.167 EJ/yr.

Phytotoxic Effect

Biomass from cup plant (Silphium perfoliatum L.) is considered a renewable energy source that can be converted into alternative fuel. Calorific syngas, a promising type of advanced fuel, can be produced through thermochemical biomass gasification. In this study, the suitability of cup plant biomass for gasification was assessed, including the process energy balance and environmental impacts of waste from syngas purification. Silphium perfoliatum L. was cultivated as a gasification feedstock in different conditions (irrigation, fertilization). The experiments were performed in a membrane gasifier. All obtained energy parameters were compared to the biomass yield per hectare. The toxic effects of liquid waste were assessed using tests analyzing germination/seed root elongation of Sinapsis alba. Leachates collected from condensation tanks of a gas generator were introduced to soil at the following doses: 100, 1000 and 10,000 mg kg−1 DM of soil. The usefulness of Silphium perfoliatum L. for gasification was confirmed. The factors of plant cultivation affected the biomass yield, the volume and calorific value of syngas and the amount of biochar. It was determined that the components found in condensates demonstrate a phytotoxic effect, restricting or inhibiting germination and root elongation of Sinapsis alba. Due to this potential hazard, the possibility of its release to the environment should be limited. Most of the biomass is only used for heating purposes, but the syngas obtained from the cup plant can be used to power cogeneration systems, which, apart from heat, also generate electricity.

Germination And Growth

Acacia raddiana or Acacia tortilis (Forsk) Hyane subsp. raddiana (Savi) Bernan, (Fabaceae) is characterized by a great ecological plasticity. It is largely used by the local populations as medicinal plants, fodder, wood energy, coal because it high calorific value. This plant thus plays a big role in rural economy because it is also appreciated in craft industry and for the clothes, tools and kitchen utensil manufacture. The study of the intensity osmotic stress effect on the germination of Acacia raddiana seeds reveals that there is a very strong negative correlation between the increase of the concentration of PEG and the germination rate (r = -0.9251). The fact remains that in spite of very small negative potential, Acacia raddiana seeds are very resistant since it coming to sprout at potential matching -6.0 MPa. In otherwise, the foliar  RWC of seedling remained stable during the 25 days of treatment at about 81.61 ± 7.61% (control) and dropped from 17th to 25th day at 32% (stressed). The growth was also affected by stress. Thus, both leaves number and stem height is reduced in stressed plants compared to controls.

Solids Content

Large amounts of wet sludge are produced annually in municipal and industrial wastewater treatment. Already in pulp and paper industry, more than ten million tons of primary sludge, waste activated sludge, and de-inking sludge is generated. Waste activated sludge contains large quantities of bound water, which is difficult to dewater. Low water content would be a matter of high calorific value in incineration but it also has effects on the volume and the quality of the matter to be handled in sludge disposal. In this research waste activated sludges from different pulp and paper mills were chemically characterised and dewatered. Correlations of chemical composition and dewatering properties were determined using multivariate analysis. Chemical characterisation included basic sludge analysis, elementary analysis and analysis of wood-based components, such as hemicelluloses and lignin-derived material. Dewatering properties were determined using measurements of dry solids content, flux and flocculant dosage. The effects of different variables varied according to the response concerned. The variables which were significant regarding cake DS increase in filtration or centrifugation and flocculant dosage needed in filtration were different from those which were significant regarding flux.

Este trabalho teve como objetivo caracterizar energeticamente a madeira e o carvão vegetal obtidos a partir da espécie Eucalyptus benthamii Maiden & Cambage para duas diferentes idades, 5 e 13 anos. Para a madeira de cada idade, foram confeccionados 48 corpos de prova, com aproximadamente 2 x 2 x 2 cm, que foram utilizados para determinação da massa específica, poder calorífico superior, análise química imediata e carbonização. Após a carbonização, as propriedades energéticas do carvão vegetal foram avaliadas a partir da massa específica aparente, rendimento gravimétrico e volumétrico, poder calorífico superior e análise química imediata. Tanto para a madeira quanto para o carvão vegetal houve influência da idade. A madeira com 13 anos apresentou maior massa específica básica e maior poder calorífico. Porém as diferenças nas propriedades físicas e energéticas da madeira das duas idades não justificam a manutenção da floresta até os 13 anos de idade, quando seu uso final é a geração de energia na forma de carvão. Em relação ao carvão, aquele produzido com madeira de 13 anos apresentou maior rendimento, enquanto o carvão vegetal de 5 anos apresentou melhor qualidade final para uso energético.Palavras-chave: Energia de biomassa; propriedades energéticas; eucalipto. AbstractDetermination of energetic properties of wood and charcoal produced from Eucalyptus benthamii. This research aimed to characterize the energetic properties of wood and charcoal obtained from Eucalyptus benthamii for two different ages, 5 and 13 years. For each timber age, we prepared 48 specimens, approximately 2 x 2 x 2 cm, used to determine specific gravity, calorific value, immediate analysis and carbonization. After carbonization, we evaluated the energetic properties of the charcoal in relation to density, gravimetric and volumetric yield, calorific value and immediate chemical analysis. As the wood as charcoal were influenced by age. The 13 years old timber revealed higher specific gravity and higher calorific value. However, the differences in the physical and energetic properties of the wood of the two ages do not justify maintaining the forest until the age of 13, as its end use is generation of energy as coal. The charcoal produced from 13 years old trees had the highest yield, while the charcoal from 5 years old trees had better quality to energy usage.Keywords: Biomass energy; energy properties; Eucalyptus.

The Impact

The aim of the study was to analyse the energy needs of selected consumers and to select the PV installed capacity in the east and west panels orientation (E-W). The analysis was carried out for two variants. The first concerned the impact of the installation power of a PV source on the contracted power in its symmetric east and west position. The second variant was the result of previous observations and studies of the authors of this paper. Thus, in this variant, the unbalanced power of PV E-W in relation to the S azimuth has been analyzed, taking into account the characteristics of the recipients' needs and the variation of the PV power installed. The analyses show that an increase in meeting the energy demand for two of the tested plants at symmetrical power distribution to the east and west occurred only when the installed power was increased to the level of approx. 1.4-1.6 of the contracted power. However, the power distribution in the E-W direction has a very strong effect on the energy amount that is generated in the power plant and cannot be used due to the lack of demand in the plant.

Sugarcane Industry

The sugarcane industry has assumed an increasingly important role at a global level, with countries such as Brazil and India dominating the field. However, this causes environmental problems, since the industry produces large amounts of waste, such as sugarcane bagasse. This by-product, which is energetically partially recovered in sugar mills and in the pulp and paper industry, can make a significant contribution to the general use of biomass energy, if the usual disadvantages associated with products with low density and a high moisture content are overcome. From this perspective, thermochemical conversion technologies, especially torrefaction, are assumed to be capable of improving the fuel properties of this material, making it more appealing for potential export and use in far-off destinations. In this work, sugarcane samples were acquired, and the process of obtaining bagasse was simulated. Subsequently, the bagasse was dried and heat-treated at 200 and 300 °C to simulate the over-drying and torrefaction process. Afterward, product characterization was performed, including thermogravimetric analysis, elemental analysis, calorimetry, and energy densification. The results showed significant improvements in the energy content, from 18.17 to 33.36 MJ·kg−1 from dried bagasse to torrefied bagasse at 300 °C, showing that despite high mass loss, there is potential for a future value added chain for this waste form, since the increment in energy density could enhance its transportation and use in locations far off the production site.

This paper reports on a study of organizational buyer attitudes towards forest biomass energy for use in heating systems.This topic warrants discussion as global energy needs grow and the Canadian forestry sector experiences economic challenges.In particular, heating systems are an appropriate introductory application for solid forest biomass because it representsan efficient and sustainable fuel use. The attitudes of organizational buyers are assessed and compared against theperceived level of importance for attitudinal items and the views held toward fossil fuels. The results demonstrate that forestbiomass is viewed favourably on environmental aspects and on some other attitudinal items of high importance. Managerialsuggestions are forwarded to guide the burgeoning sector in its attempt to build awareness and strengthen its perceivedimage among organizational buyers. Key words: biomass, biomass fuel, attitudes of organizational buyers, biomass as an alternative heat and energy source
