1. Study for the incorporation of wood ash in soil-cement brick
Abstract This study aimed to produce soil-cement brick with wood ash incorporation coming from the textile industry. The wood ash was a partial substitute for soil and cement in the manufacture of bricks. 7 formulations were made with different proportions of substitution: 10%, 20%, and 30%. It was noticed that the substitution of cement by wood ash in 10% r

8. THERMAL PROFILE OF WOOD SPECIES FROM THE BRAZILIAN SEMI-ARID REGION SUBMITTED TO PYROLYSIS
ABSTRACT The objective of this study was to evaluate the thermal decomposition profile of 10 wood species from the semi-arid region of Brazil using thermogravimetric analysis (TGA) to investigate their potential as biomass energy sources. First, flash carbonization was carried out in a muffle furnace, in which wood samples were heated to a maximum temperatur

10. Reducing the leachability of nitrate, phosphorus and heavy metals from soil using waste material
Abstract Contaminants like nitrate (NO3), phosphorus (P) and heavy metals in water are often associated with agricultural activities. Various soil and water remediation techniques have been employed to reduce the risk associated with these contaminants. A study was conducted to examine the extent of leaching of heavy metals (Cd, Ni, Pb and Cr), NO3 and P. Fo

11. Energetic use of wood waste in one center for the production of red ceramics in São Paulo State / Uso energético de resíduos madeireiros em um pólo de produção de cerâmicas vermelhas do Estado de São Paulo
The use of forest biomass is an important alternative of renewable energy source, economic, technical and environmentally viable, fighting for space with other energy sources, more expensive or non-renewable, such as natural gas, electricity, diesel and LPG. Within the industrial sector, biggest consumer of biomass energy, the segment of red ceramics represe

12. Caracterização de biomassas brasileiras para fins de aproveitamento energético / Characterization of brazilian biomasses for energy recovery
New energetic alternatives have been the subject of discussion about conservation of natural resources. Such discourses are based mainly on reducing emissions of greenhouse gases and other pollutants, caused mostly by the use of fossil fuels, major source of energy today. In view of the applicability of biomass as energy input, this paper presents an experim
