Nagipe da Silva Paulo nagipe@uenf.br A. Viana Gusmão Vieira P. Rodrigues <p>Aquatic macrophytes are important components of aquatic habitats. However, the overgrowth of aquatic plants can cause severe problems for the management of bodies of water. As a result, these plants must be removed and disposed of as waste. However, the usage of this biomass as a substrate in biogas plants would appear to be more beneficial. The present work deals with the anaerobic digestion (AD) of macrophytes species that cause inconvenience to power generation at hydroelectric plant in Minas Gerais - Brazil. The study examines the following macrophytes species; <em>Salvinia molest</em> <em>Oxycarium cubense</em>, <em>Eichhornia crassipes</em>, <em>Pistia stratiotes</em> and <em>Brachiaria</em>. The experiments were carried out as stainless steel reactor with temperature, agitation and pressure control. As pre-treatment of macrophytes was used heat treatment at 120°C and pressure of 1.6 atm. The maximum methane content was 60% during 40 days digestion time, for Brachiaria of higher lignin content. The result obtained, mainly with Brachiaria demonstrates the efficiency of pre-treatment for the lignocellulosic samples.</p> 2021-01-18T00:00:00+00:00 ##submission.copyrightStatement##
