“…Our findings also demonstrated the logging wood waste biomass have a high proportion of volatile matter that allows biomass to ignite easily and together with the fixed carbon to volatile matter ratio determines the flame stability during combustion (Table 3.). This phenomenon inline with the previous results reported by Virmondand co-workers [17]. Moreover, the results werealso demonstrated that the chemical composition of logging wood waste biomass studied was almost similar,while the highest of high calorivic value (HCV) was obtained from S. laevis to gave 17.90 MJ/kg and followed by S. leprosula (17.38 MJ/kg),S. bracteolata (17.09 MJ/kg)and S. gibbosa (16.86 MJ/kg), respectively (Table 4.).…”

Abstract. In this work, the wood waste biomass from the logging activity of the natural forest area in East Kalimantan, Indonesia has been characterized in regards to the physicochemical properties and energy. The four species of wood waste biomass were Shorealeprosula (red meranti), Shoreabracteolata (white meranti), Shoreagibbosa (yellow meranti), and Shorealaevis (bangkirai). The total amount of wood waste biomass produced from the logging activity was 557.87 m 3 /plot(5.58 m3 ha -1 ). The waste biomass was identified as log end part (40.07%), bucking (27.39%), twigs (14.61%), stump (12.0%) and branch parts (5.92%), respectively. Among the four species studied, we observed that the highest volume of wood waste biomass was obtained from S. leprosulagiving 48.40% and followed by S. laevis 47.40%, and the last was S. bracteolata. From the field study, We noticed that the waste of wood biomass was not only yielded from the part of the log harvested such as branch, stump, log end and bucking processes but also reached from the damaged trees around the felling trees location and skidding operation. In general, the chemical composition of wood waste biomass studied was almost similar, while the highest calorivic value (HCV) was obtained from S. laeviswith value of 17.90 MJ/kg and followed by S. leprosula of17.38 MJ/kg, S. bracteolataof 17.09 MJ/kg, and S. gibbosa of 16.86 MJ/kg.The logging wood waste biomass was estimated sufficient to provide and supply 3668.62 GJ energy, to generate ±1,019 MWh electricity that equivalent to ±10.19 MWh electricity potency per hectare.

RESUMO -O lodo de esgoto é o principal subproduto gerado no tratamento de águas residuais urbanas e representa um desafio quanto a sua disposição final. O objetivo deste trabalho foi caracterizar e avaliar o comportamento térmico de quatro amostras de lodos (anaeróbios e aeróbios) em atmosfera inerte e oxidante. O poder calorífico inferior dos lodos variou entre 7,58 MJ.Kg -1 e 14,55 MJ.Kg -1 e a matéria volátil entre 44,68% e 63,50%, indicando o potencial energético deste combustível e viabilizando seu uso como fonte alternativa de energia. Foram observados dois comportamentos térmicos diferentes de acordo com o tratamento dos lodos. Para as amostras de lodos anaeróbios os perfis termogravimétricos de pirólise são idênticos aos de combustão. Para o lodo aeróbio, os perfis termogravimétricos de pirólise e combustão coincidem, exceto na última parte do perfil de combustão, onde uma decomposição final aparece como consequência da combustão do char formado anteriormente. O comportamento diferente está associado a estabilização anaeróbia e aeróbia que os lodos sofre durante o tratamento nas estações de tratamento de esgotos. INTRODUÇÃOO lodo é o principal resíduo gerado durante o tratamento mecânico, biológico e químico dos esgotos. Este produto é constituído por matéria orgânica (hidrocarbonetos, aminoácidos, proteínas, gorduras, celulose, microrganismos), e uma grande variedade de substâncias inorgânicas. Devido, ao crescimento da população das cidades e a melhoria nos sistemas de tratamento de efluentes a quantidade de lodo de esgoto gerado tem aumentado, representando um desafio quanto a sua disposição (Rulkens, 2008).Como lodo tem relativamente alto "valor calórico", as tecnologias de valorização energética, como a combustão, pirólise, gaseificação e co-combustão tem ganhado atenção Na combustão ocorre à completa oxidação dos compostos orgânicos do lodo a altas temperaturas liberando CO 2 e água. O volume dos lodos é reduzido e é gerada energia. No processo de pirólise os lodos são aquecidos a uma temperatura de 350-500 °C na ausência de oxigênio, gerando char, óleos de pirólise, vapor de água, cinzas e gases combustíveis. O combustível que é produzido pode ser usado em motores de Área temática: Engenharia Ambiental e Tecnologias Limpas 1

“…In a recent publication, the potential for application of various agroindustrial solid residues as alternative energy sources in thermochemical processes was assessed by characterizing their properties -including proximate and ultimate composition, energy content, thermal behavior, composition and fusibility of the ashes -and correlating them to the characteristics required for the optimal operation of pyrolysis, gasification and combustion processes (Virmond et al, 2012).…”

“…The latter has special importance given that soil can be incorporated into the biomass and can potentially change the biomass ash composition and properties. One of the important features of biomass materials is the presence of significant amounts of alkali and alkaline earth metal species (mainly K, Na, Mg and Ca), which tend to volatilize during pyrolysis, gasification and combustion (Virmond et al, 2012). The alkali metals can be easily converted to new compounds during combustion, may interact with fuel gases (typically sulfur and chlorine) and with the reactive parts of the other materials inside the furnace.…”

“…With an average heating value of 4324.45 kcal.kg -1 on a dry basis (Virmond et al, 2012), the annual fuel value is estimated at 1.427x10 9 kcal. The constraints related to the availability of additional land suggest that second-generation biofuel industries and biorefineries should focus on currently available feedstock sources in the initial phase of the industry.…”

-Besides high industrial development, Brazil is also an agribusiness country. Each year about 330 million metrics tons (Mg) of biomass residues are generated, requiring tremendous effort to develop biomass systems in which production, conversion and utilization of bio-based products are carried out efficiently and under environmentally sustainable conditions. For the production of biofuels, organic chemicals and materials, it is envisaged to follow a biorefinery model which includes modern and proven green chemical technologies such as bioprocessing, pyrolysis, gasification, Fischer-Tropsch synthesis and other catalytic processes in order to make more complex molecules and materials on which a future sustainable society will be based. This paper presents promising options for valorization of Brazilian agroindustrial biomass sources and residues originating from the biofuel production chains as renewable energy sources and addresses the main aspects of the thermochemical technologies which have been applied.
