The increasing concern about the environment has been mobilizing some market segments. Several governmental bodies and industries are preparing to apply an environment policy that diminishes the negative impacts to the nature. The industrial residue, after being generated, needs an adjusted destination, since, beyond creating potential environment problems, the residues represent losses of raw materials and energy, demanding significant investments in the pollution controlling treatments. The food industry produces a series of residues of high value of (re)utilization. Many works study the residues bioutilization such as the crushed sugar cane for protein enrichment of animal ration. In this work it will be presented a study of a possible usage of the crushed sugar cane for the production of Spirulina with satisfactory protein increment results when compared with other results gotten in literature.The increasing concern about the environment has been mobilizing some market segments.

Inúmeros órgãos governamentais e indústrias estão se preparando para aplicar uma política ambiental que diminua os impactos negativos à natureza. O resíduo industrial, depois de gerado, necessita de destino adequado, pois, além de criar potenciais problemas ambientais, os resíduos representam perdas de matérias-primas e energia, exigindo investimentos significativos em tratamentos para controlar a poluição. A indústria de alimentos produz uma série de resíduos de alto valor de (re)utilização. Muitos trabalhos estudam a bioutilização de resíduos tais como o bagaço de cana-de-açúcar para enriquecimento protéico de ração animal. Neste trabalho será apresentado um estudo sobre a possível utilização do bagaço de cana-de-açúcar para produção de Spirulina com resultados de incremento protéico bastantes satisfatórios quando comparados com outros resultados obtidos na literatura.
