Item Caracterização energética da maravalha gerada no processamento mecânico da madeira em marcenarias de pequeno porte(2023-09-21) Campelo, Irlan Paulo Ferreira; Braz, Rafael Leite; http://lattes.cnpq.br/7332493832361305; http://lattes.cnpq.br/1038816224446032In Brazil, electricity consumption has grown increasingly, the search for other energy sources must be discussed and worked on, especially in some regions of the country. Brazil's energy crisis is marked by political, economic and environmental factors, which are directly related to the country's difficulty in maintaining its energy supply. Given this context, several sectors have sought new energy alternatives in order to meet the required demand, investing increasingly in sustainable alternatives. Thus, the objective of the work was to evaluate the energy potential of wood shavings generated in the mechanical processing of wood in small carpentry workshops through its energetic properties. The material used was maçaranduba and sucupira wood shavings, collected in two carpentry workshops in the municipality of Camaragibe - PE. The analyzes carried out were: moisture content, bulk density, content of volatile materials, ash, fixed carbon, higher, lower and useful calorific value, extractive content, lignin and holocellulose content. The results of the chemical and calorimetric analyzes of the wood shavings, although they indicate that Treatment T1 had a slight advantage over Treatment T2, these differences are minimal and can be attributed to natural variations in the properties of the wood shavings. Therefore, the wood shavings materials analyzed have promising energetic properties. Its high energy density, low moisture content and favorable chemical composition indicate that wood shavings can be an excellent option as an energy source. This discovery suggests that wood shavings can serve as an efficient and sustainable alternative in replacing non-renewable energy matrices, thus contributing to the diversification and improvement of the energy supply, meaning that waste/disposal can be reused and used directly for generating energy or obtaining briquettes, pellets.
