Biomassa, Recursos naturais, Usos potenciaisResumo
O objetivo de se tornar uma sociedade baseada na utilização racional dos recursos naturais, tem levado à consideração de muitas alternativas pela academia e setor industrial. O setor florestal pode ter um destaque especial na tentativa de atingir esses objetivos ao utilizar resíduos de seus processos. Um dos requisitos mais importantes da sociedade é a produção de energia. Coprodutos do beneficiamento da madeira e das usinas de celulose podem ser utilizados no desenvolvimento da geração de bioenergia. A densificação da biomassa envolve questões de manuseio, transporte e armazenamento e, ainda, quando resíduos florestais industriais como a lignina são adicionados a essa biomassa, o produto energético final pode ter algumas propriedades melhoradas, agregando valor à cadeia produtiva. O objetivo deste estudo foi avaliar o aproveitamento do resíduo industrial lenhoso, a serragem de Joannesia princeps Vellozo enriquecida com lignina Kraft como aditivo, visando à produção de briquetes. Um dos principais resultados deste trabalho foi a possibilidade de se obter um briquete com melhores propriedades (maior densidade aparente e maior resistência) ao usar 6% de lignina Kraft como aditivo e pressão de 1500 PSI.
