Abstract

The treatment of the solid waste responsible of environmental pollution is one of the most important concerns at the present time; as appropriated methods for the handling and discarding are seek. Lignocellulosic materials incorporation in the manufacture process is an increasing trend due to the production of environmentally friendly products which are similar to those made with commercially available raw materials. Rice hulls are a byproduct of the rice milling process. Rice hulls were characterized according to the ASTM procedures. Relevant characterization results are the alpha cellulose (19.736%) and lignin (6.270%) content of the rice hulls.
