Brazil stands out internationally in the production and commercialization of wood products. Although the external and internal demand for these products is met by the Brazilian forestry sector, challenges related to the internal management of lignocellulosic waste are evident, as the country has structural difficulties in the sector of solid waste management. Therefore, the objective was to comparatively analyze the performance of the most abundant lignocellulosic materials in the Brazilian market, regarding energy recovery at the end of their life cycles. Pine wood treated with chromed copper arsenate (CCA), untreated pine wood, eucalypt wood treated with CCA, untreated eucalypt wood, uncoated medium density fiberboard panel (MDF), and MDF panel with melamine coating were sampled. The characterization included thermogravimetric analysis (TGA), scanning electron microscopy (SEM) with energy-dispersive x-ray spectroscopy (EDXA), and elementary analysis (EA). The presence of the CCA salts and the melamine coating reduced the energy potential of the biomass, altering the burning behavior and significantly increasing the amount of generated ashes. They also caused an increase in the concentrations of copper (Cu), chromium (Cr), arsenic (As), and cadmium (Cd) in the wood ashes as well as lead (Pb) and chromium in the panel ashes.

The licuri nut shell is a potential source of biomass for energy production. The aim of this study was the physicochemical characterization of the licuri shell, focusing on the increase of its use as a fuel. The material was collected in Caldeirão Grande-BA and the characterization included a wide range of analyses such as: moisture content, bulk density, particle size distribution, ash content, volatile matter, fixed carbon, high heating value (HHV), hot water and cyclohexane/ethanol extractions, Klason lignin content, and thermogravimetric analysis (TGA). The obtained results were: moisture content (11,1%), HHV (4652 kcal.kg-1), Klason lignin content (36,86%), volatile content (74,91%), and fixed carbon (21,19%). The results showed that the material can be considered suitable for the purpose of generating energy when compared with other types of biomasses. The ash content (3,9%) and the extractives content (46,75%) are in accordance with the values observed for the babassu nut shell, Brazilian nut shell, and coconut. Finally, by the TGA analysis, it was observed that the degradation peak occurred at 272°C with a loss of 65% of weight. With these results, the licuri nut shell has shown to be potentially promising for the energy production.

The aim of this study was to apply geostatistics to predict the spatial pattern of variations in moisture content of eucalyptus wood chip piles to generate subsidies for adequate sampling and material handling. Wood chip piles were installed in three different storage cycles using newly cut material for 7, 30, and 60 days. Sampling was performed in axial (top, middle, and base) and lateral positions, so that all samples were georeferenced in relation to the distance from the ground and the center of the pile. Moisture values were submitted to geostatistical analysis and kriging. The results confirmed the spatial dependence of moisture content over the piles stored at 7 and 30 days; however, the effect of rainfall was crucial to reduce the spatial dependence of moisture content. The results showed that geostatistics is a useful tool for the creation of reliable sampling protocols.
