ALTERNATIVAS PARA A GERAÇÃO DE ENERGIA RENOVÁVEL NO BRASIL: A OPÇÃO PELA BIOMASSA
Provedor de dados: 31
Autores: Marconato,   Mariane Silva; Santini,   Giuliana Aparecida.
Durante muito tempo, os recursos fósseis e hídricos foram os grandes propulsores da civilização e da economia. O Brasil também se apoiou nessas fontes energéticas para o desenvolvimento de atividades industriais, agrícolas, de serviços e da própria sociedade. Entretanto, vive-se hoje uma crise no abastecimento energético, em função da problemática geopolítica, econômica e ambiental em torno da extração e comercialização desses recursos, uma vez que possuem ainda, caráter não renovável, portanto, finito na natureza. Os escassos investimentos governamentais e a abertura econômica do setor energético resultou no fim do monopólio energético, o que favoreceu a implantação de sistemas alternativos, na maioria, advindos da biomassa. Dentre esses, destaca-se a...

Economic Feasibility of Commercial Algae Oil Production in the United States
Provedor de dados: 31
Autores: Fischer,   Bart L.; Richardson,   James W.; Outlaw,   Joe L.; Allison,   Marc S.
A Monte Carlo simulation model was constructed to analyze the economic feasibility of growing algae as a renewable fuel source.   Increasing growth rates, pond water depth, oil content, and facility size are important for ensuring the economic viability of a commercial algae facility.

Choice of optimum feedstock portfolio for a cellulosic ethanol plant  – A dynamic linear programming solution
Provedor de dados: 31
Autores: Kumarappan,   Subbu; Ivanic,   Rasto.
When the lignocellulosic biofuels industry reaches maturity and many types of biomass sources become economically viable, management of multiple feedstock supplies – that vary in their yields, density (tons per unit area), harvest window, storage and seasonal costs, storage losses, transport distance to the production plant – will become increasingly important for the success of individual enterprises. The manager’s feedstock procurement problem is modeled as a multi-period sequence problem to account for dynamic management over time. The case is illustrated with a hypothetical 53 million annual US gallon cellulosic ethanol plant located in south west Kansas that requires approximately 700,000 metric dry tons of biomass. The problem is framed over 40...
