Lignocellulose has been investigated in depth during the last decade because it offers a wide range of possibilities for its transformation into necessary and valuable consumer products, which are currently obtained from non-renewable fossil resources. Based on these perspectives, the concept of "biorefinery" was coined as an approach aimed at integrating green chemistry into processes aimed at obtaining chemical products, materials and renewable fuels, using technologies with low environmental impact. Therefore, it is necessary to design biotechnological processes that allow all these compounds to be produced from renewable resources, such as lignocellulosic waste and byproducts, in a circular economy context.
