Literature Review:

Biorrefinaria é um importante conceito que pode ser aplicado na melhoria de processos industriais para que sejam mais sustentáveis, reduzindo os resíduos e tenham menos custos operacionais. O processamento de biomassa de microalga é muito oneroso e, até agora, somente algumas microalgas têm produtos que são viáveis para comercialização. Combinar esse conceito a outros, como intensificação e integração de processos pode ajudar a reduzir custos e torná-lo mais atraente para ser aplicado na indústria. Dunaliella salina é uma das microalgas mais importantes estudadas atualmente e seu processo explora apenas 10% de seus compostos na produção de beta-caroteno. Estudos mostram que existem outros compostos que podem ser explorados em outros processos numa abordagem de biorrefinaria.

Biorefinery is an important concept that can be applied to improve the industrial processes, making them more sustainable, reducing waste and also reducing costs of operation. Algal biomass is too onerous to be exploited and until now, only a few microalgae have products that are feasible to commercialize. Combining this concept and other ones, such as intensification and integration of processes can also help reduce the costs and it can become more attractive to be applied in industry. Dunaliella salina is one of the most important microalgae studied nowadays. Currently, its process exploits only 10% of its compounds in the beta-carotene production. Studies show that there are other compounds that can be exploited and other processes that can be combined in a biorefinery approach.
