This study aimed to determine the effects of physical, chemical and water-holding capacity of Quartzarenic Neosol, Red Latosol and Red Nitosol on tree growth, physicomechanical properties and anatomical features of wood from 33-year-old C. citriodora plantations. More clayey soils with higher water availability, such as Red Latosol and Red Nitosol, increased the mean annual increment and heartwood percentage. In more sandy soils, such as Quartzarenic Neosol, density increased, but the size and d...

We aim to determine the growth performance of two 20-year-old silvopastoral systems comprising two timber trees, a palm tree), a short-lived perennial shrub, a forage and livestock; and to investigate fibre features and certain physical and mechanical properties of two timber trees (Myracrodruon urundeuva and Peltophorum dubium) in two plantation systems. The first system is called MP with two timber trees and the second one is called MPS with two timbers and a palm tree. The studied systems sho...

This study aimed at investigating the binderless densification of biomass for the production of a durable solid biofuel by mixing cassava rhizome, sugarcane bagasse, and sugarcane straw. Six different treatments were applied with specific percentages of these three biomass feedstocks for the densification in a lab-scale press with heating of 120 °C. Three blend treatments and three 100% material treatments (without mix) were analyzed. Achieved briquettes were examined via various tests including...

Abstract The recycling of materials found in municipal solid waste (MSW) is preferable to energy recovery; however, parts of the residues are rejected and sent to landfills. Rejects can be processed and used as refuse-derived fuel (RDF); nevertheless, an assessment of the fuel properties is relevant. This work evaluated the fuel potential of rejected MSW by manually sorting recyclable products, dominated by discarded recyclable solid waste (DRSW), aiming at recovery using it as RDF in thermochem...

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 mark...

Abstract Cassava waste has the potential to be used as an energy source. The aim of this study was to analyze the effects of pressure densification on the properties of cassava residue briquettes, especially on the strength of the briquettes. It was used three compaction pressures: 102, 153, and 204 MPA and three pressing hold times: without holding pressure time, 60s, and 120 s, to produce briquettes without heating and verify their formation concerning the compaction. The proximate analysis pr...

Abstract An expansion of planted Eucalyptus spp. forests can supply an important part of society's demand for biofuels. To do so, a diversity of genetic materials field-grown under seasonal drought stress, different soil type and technological wood qualities have to be evaluated in new forest frontiers. The aim of this study was to evaluate the yield and wood characteristics of five Eucalyptus spp. clones in a field experiment with regard to E. urophylla x E. grandis, E. resinifera x E. grandis,...

The use of biomass as a renewable source of energy is an important characteristic of the Brazilian energy matrix. The energetic use of agricultural and forest biomass is a way of reducing production costs, taking advantage of residues, and reducing the use of fossil fuels. The objective of this study was to analyze the biomass market in the State of Sao Paulo to define which materials have more suppliers in the region and which have favorable properties for burning. For this, information was col...

Nowadays, countries produce approximately 1700 million tons of sugarcane per year. However, many countries now find it difficult to produce sufficient energy, generating a relevant socioeconomic impact. The objective of this work is to study the potential energy of sugarcane bagasse after decomposing fungus process. This fungus, the basidiomycete Pleurotus ostreatus, acts in the bioconversion of lignocellulosic residues, through the decomposition of the solid substrate in a process of enzymatic ...

Abstract The new concept of integrated biorefineries has significantly changed pulp and paper industries. Lignin, which until then was only burned to generate energy, is now an important raw material for new products production. Kraft lignin (KL) fractions obtained by sequential fractionation with five organic solvents. This sequence allows to extract fractions from lower molar mass to higher molar one, resulting in more homogeneous samples. Lignin’s fractions were characterized by FTIR, GPC, TG...
