Abstract

Searching to insert biomass into the national competitive market, some studies are necessary to have greater efficiency in its use and better management, taking advantage of waste that is usually discarded. The low use of agricultural waste for energy generation is associated to their characteristics that complicate their use, such as: low density, low calorific value and high moisture content. Combining briquetting and torrefaction processes can solve these problems and make it possible to use biomass waste. Among the agricultural waste found in Brazil, the cassava rhizome is a residue generated during the harvest of the cassava root that is discarded in an wrong way because it has no aggregated economic value. In this project it is proposed to perform torrefaction cassava rhizome briquettes in a period of one year, using temperatures of 200, 250 and 300ºC, and residence times of 30 and 60 minutes for each torrefaction temperature. To determine the quality of torrefied briquettes their physical and chemical characterization must be carried out, by and tests of: Bulk density; Proximate Analysis; High Heating Value; Density; Durability; and Moisture Resistance. Results will be analyzed statistically and compared with the literature data.
