PHYSICAL AND CHEMICAL PRETREATMENTS USED FOR BIOETHANOL PRODUCTION FROM LIGNOCELLULOSIC BIOMASS - REVIEW

In the last decade, environmental protection is one of the major challenges. It is necessary to ensure the protection of the environment and the conservation of natural resources, in accordance with the requirements of a sustainable economic and social development. The most important impact of moder...

It is necessary to ensure the protection of the environment and the conservation of natural resources, in accordance with the requirements of a sustainable economic and social development.
