Nigeria is a developing country with an insufficient supply of energy to meet the continuously growing demand. However, there are several biomass resources available within the country. This paper presents a desk review, which investigates the potential resources for biomass energy generation within the country. Energy policies to aid biomass use as an energy source within the country were also reviewed. Biomass resources identified within Nigeria include forest residues, agricultural residues, human and animal wastes, aquatic biomass, and energy crops. However, several of the resources, particularly agricultural residues, have competing uses, such as livestock feed and soil rejuvenation. An estimation of the technical energy potential of the biomass resources revealed that about 2.33 EJ could be generated from the available resources in Nigeria. Agricultural residues have an energy potential of about 1.09 EJ, with cassava, maize, oil palm, plantain, rice, and sorghum being the major contributors. Animal wastes, municipal solid waste, and forest residues have energy potentials of 0.65, 0.11, and 0.05 EJ, respectively. The potentials of wood fuel and charcoal are 0.38 and 0.05 EJ, respectively. The study found that despite the available potential and existing policies, not much has been done in the implementation of large-scale bioenergy within the country. However, there has been laboratory and research-scale investigations. The review suggests that more policies and stronger enforcement will aid bioenergy development within the country. From the review, it has been suggested that the agricultural sector needs to be developed to generate more biomass resources. More research, development, and implementation have to be carried out on biomass resources and bioenergy generation processes. The production of non-edible energy crops in marginal lands should also be considered prime to the development of bioenergy within the country.

“…This shows that the smaller the particle size, the higher the RD value. Higher density values indicate better-quality briquette because higher density briquettes are more carboncompact so the resulting calorific value is higher (Tumuluru and Fillerup, 2020;Orisaleye, Jekayinfa, Adebayo, Ahmed, and Pecenka 2018).…”

The purpose of this study was to determine the learning outcomes of Vocational High School students about biobriquette using learning media in the form of instructional video and job sheet through experimental demonstration.The study was conducted through the pretest, theoretical explanation of briquettes using video learning, the first posttest, the presentation of material using job sheet media, and the second posttest. Briquettes production was done through drying, carbonizing, grinding carbon using a sawmill, sieving, molding, and drying. In the briquettes production, we varied the composition ratios between coffee grounds and soybean peel (i.e. 50:50; 60:40; 70:30; 80:20; and 90:10) and particle sizes (i.e. 1000, 600, and 250 µm), which were mixed with tapioca flour as the binder. Physical characteristics of briquettes were analyzed through some analyses. Based on the physical characteristic results of briquettes, briquettes at ratio (60:40) with a particle size of 250 µm have good Compressed Density (CD), Burning Rate (BR), and Specific Fuel Consumption (SFC) characteristics. Based on the evaluation of the pretest and posttest results, the learning media improved students' knowledge and understanding of biobriquette. This study brings new information about the need for biobriquette learning media with experimental methods to improve vocational students' comprehension.

M.; Bufalino, L. 525 possível, por exemplo, adaptar sistemas de gaseificação para aproveitamento de biomassas desse tipo que são frequentemente subutilizadas, conforme já demonstrado para a casca de arroz (INDRAWAN et al, 2017). Outra solução seria sua densificação mecânica por peletização ou briquetagem para tornar seu manuseio, transporte e processos de conversão em energia mais eficientes (ORISALEYE et al, 2018). A pirólise pode ainda ser utilizada para converter biomassa de baixa densidade em um produto intermediário de alta densidade (bio-óleo), que pode ser, posteriormente, processado em combustíveis de transporte, como diesel e gasolina (SHARMA et al, 2015).…”

Comparação da qualidade dos tecidos do pecíolo de buriti (<i>Mauritia flexuosa</i> L. f.) para combustão e carbonização

Apesar da importância social, cultural e econômica para a Região Amazônica, o potencial energético da Mauritia flexuosa, popularmente conhecida como buriti, ainda não foi explorado para ampliar as possibilidades de uso dessa espécie pelas comunidades locais. Assim, o objetivo deste trabalho é comparar o potencial dos tecidos que compõem o pecíolo de Mauritia flexuosa para combustão e carbonização. O miolo e casca do pecíolo foram separados e caracterizados por composição química (extrativos removíveis por água e totais, lignina e cinzas), umidade base úmida, composição imediata (teores de materiais voláteis, carbono fixo e cinzas), densidade básica, poder calorífico superior e análise termogravimétrica em atmosfera inerte de N2. Os dois tecidos do pecíolo de Mauritia flexuosa apresentaram vantagens para finalidades bioenergéticas, como: baixo teor de cinzas (≤ 2%), além de teor de carbono fixo (≈ 18%) e poder calorífico superior (≈ 18 MJ kg-1) adequados. Para miolo e casca, os teores de lignina (19 e 28%, respectivamente), extrativos (8,9 e 5%, respectivamente), e densidade básica (0,041 e 0,267 g cm-3, respectivamente) diferiram significativamente. Contudo, a composição imediata dos tecidos não foi influenciada por essas diferenças, ao contrário do poder calorífico e densidade energética. O comportamento termogravimétrico demonstrou taxa de degradação superior e rendimento final em massa inferior (7%) para o miolo em relação à casca. A casca apresentou melhor qualidade para combustão e carbonização em comparação ao miolo. Esse resultado é vantajoso para as comunidades extrativistas da Amazônia, pois a casca é um resíduo do processamento do pecíolo para obtenção do miolo, destinado à produção de artesanatos. Pela baixa densidade básica, o miolo é mais indicado para torrefação, densificação, pirólise para geração de bio-óleo e produção de filtros naturais e carvões ativados do que para combustão direta e carbonização.
