1. Energy balance and CO2 emission in mechanized biomass harvesting in pine stands under thinning
Abstract: Biomass is an important component of the Brazilian energy matrix, with a potential contribution of co-products from thinned forests. The aim of this work was to evaluate the energy balance and CO2 potential emission in mechanized biomass harvesting operations in Pinus taeda stands at 9 and 10 years-old and under thinning, searching to support the

7. Qualidade da Madeira Serrada e dos Painéis Colados Lateralmente Obtidos de um Plantio de Eucalyptus saligna Smith Visando o Segmento Moveleiro / Quality of the Sawnwood and Glued Panels Obtained of a Eucalyptus saligna Smith Plantation for Furniture Industry
In this research were studied thirty trees of Eucalyptus saligna Smith wood, sampled in a twenty year-old plantation located in Seropédica/RJ. Each tree supplied a log with 2.30 meters in length for the study of the sawn process and panels production (PCLs). The processing of the logs was made in the LPZ Madeiras and Artefatos Ltda sawmill - Piraí/RJ, bein

8. Avaliação técnica e econômica do corte de Pinus com harvester / Technical and economical evaluation of the cut of Pinus with harvester
In the Brazilian forest sector, several companies use modern technologies at the production phases. Specially in the case of the planted forests, those technologies are used from the obtainment of the seedlings until the delivery of the wood in the industry yards. The harvest has a distinguishable position in composing the final cost of the wood. In some cas
