Abstract

Aquatic plants (E.crassipes, E.azurea, E.heterosperma) are a type of macrophytes, which help debugging contaminated effluents. The continued growth and proliferation of these plants, which

are considered as a weed, can be used to develop materials for biofuels. Because they are made

from biomass waste-100% organic green materials, they are more environmentally friendly.

The aim of this study is to evaluate the conditions for adding value to this waste material, along with

other byproducts of agricultural crops such as rice husks.

The analysis of 3 macrophyte species and rice husks found in the swamp system Ayapel-Cordoba is performed using the elemental chemical analysis techniques, analysis total mercury by atomic absorption spectroscopy, thermogravimetric analysis, optical microscopy, calorific value and percentage of ash and moisture. Subsequently it was evaluated the humidity and compacting pressure conditions and suitable particle size to obtain a solid biofuel that can be adapted to practical systems and reproducible conditions for the region. The characterization of the materials showed that it is possible to develop a solid biofuel from compressed biomass, systematically increasing the density and some thermochemical properties of each kind of macrophyte and some plant materials.
