Abstract
One of the main requirements for modern industrial processes is the requirement to minimize harm to the environment. Processing of plant biomass is considered one of the most promising areas for obtaining industrially significant products. Biotransformation processes of plant raw materials are among the most environmentally friendly processes. This paper presents a scheme for the biotransformation of giant miscanthus biomass into bioethanol, bacterial nanocellulose and lactic acid. This scheme was evaluated from the point of view of obtaining maximum yields of target products and minimizing the impact on the environment. It is possible to clearly note the advantage of one-stage processing of giant miscanthus with a dilute solution of nitric acid, this method allows to increase the yield of bioethanol by 11-40%, bacterial nanocellulose by 13-30%, lactic acid by 7-28%, compared with other methods of pre-treatment. In this case, environmental factors have the lowest values, and the most environmentally friendly is the transformation of giant miscanthus biomass into bacterial nanocellulose.
