Cascas de arroz foram estudadas para exame do seu potencial na produção de bíogás na Seção de Fitoquímica. O material foi tratado previamente com 5, 10 e 15% de NaoH p/p e incubado nos níveis de 40 e 60º C de temperatura. Os resultados mostraram que casca de arroz não foi bom material para produzir metano e que a produção de gases aumentou com a temperatura e a concentração de álcali até 10%. Rica hulls were studied in order to examine their potential for biogas production. The material was previously treated with 5, 10 and 15% NaOH W/W and incubated at temperatures of 40 and 60º C. Results showed that rice hulls were not good for methane production, but the total production of gases increased with temperatura and alcali concentration up to 10%
