| ABSTRACT: This study aimed to evaluate the quality of forest biomass energy, coming from the Caatinga, for different storage times in the field. The study was conducted in southern Piauí, between January and February (rainy season). Samples were collected containing branches and trunks of various species, and samples of branches and trunks separately in 5 sample units of 20x20m. Samples were evaluated in the general state freshly harvested and samples of branches and logs after 15 and 30 days of storage in piles in the field. The analyzes carried out were: moisture content on wet basis, ash content and calorific value. Moisture content of freshly harvested biomass ranged from 39% with two days after cutting to 79% in biomass cut and left distributed in the... |

| ABSTRACT: The pelleting of forest and agricultural materials, mainly because many residues from both industries can be used in this process, has been an alternative in obtaining added value products to energy generation. Thus, the aim of this study was to evaluate the energy quality of the pellets produced from forest and agricultural residues as raw materials and to verify the utility of the thermogravimetric analysis (TGA) and the differential thermogravimetric analysis (DTG) in characterizing the behavior of the pellets during the combustion process. Four residues were used: (1) Pinus spp. woodchips, (2) apple pruning residues, (3) aciculated dry branches of Araucaria angustifolia and (4) A. angustifolia empty-seeds. Chemical composition of the raw... |

| ABSTRACT: This paper aimed to evaluate the technological properties of particleboards produced with particles of unconventional species, bamboo of the species Phyllostachys edulis, and of the genus traditionally used by the sector for the production of the particulate panels in Brazil, Pinus spp.The bamboo splints of 3 years old were collected in Frei Rogério, Santa Catarina, being transformed into particles in a mill hammer, while the particles of Pinus spp. were collected from the industrial process of MDP production in Bonet Madeiras e Papéis Ltda Company in Santa Cecília, Santa Catarina. The company used eight-year-old logs of P. taeda and P. elliottii from the thinning process, without distinction of the species. The experiment was composed of five... |
