Popis: | The production of handmade paper is a sustainable process that has a relevant social and economic function, especially in developing countries. In the search for alternative, renewable and low-cost sources for cellulose and handmade paper production, we evaluated the morphological characteristics and chemical composition of fibers of leaves and culms from Arundo donax, a fast-growing invasive grass that was introduced in several countries, including Brazil. The fibers of A. donax are long (leaf = 1.73 mm; culm = 1.26 mm), with thick cell walls (leaf = 4.97 µm; culm = 5.36 µm), which provide folding endurance and result in a rougher and more voluminous paper. Additionally, the high values of cell wall fraction (leaf = 78%; culm = 82%) indicate great fiber stiffness. The relatively high values of cellulose (leaf = 38.9%; culm = 39.4%) and low values of lignin (leaf = 12.1%; culm = 13.0%) in the fibers make its use in paper production advantageous, as it reduces costs with chemical products in pulping. Fibers from A. donax are a viable alternative material to produce cellulose and handmade paper or can be mixed with other raw materials to produce different types of paper. |
