Biochar produced from poultry litter waste

Brazil generates substantial quantity of poultry litter waste because of its worldwide prominence in the production of broiler chickens. The volume of the poultry litter biomass generates considerable environmental impact. The objective was to characterize the biochar produced from poultry litter residue under different conditions with the aim of determining the best residence time and temperature. Poultry litt...

Physical-chemical and thermal characterization of powder eucalyptus bark

Made available in DSpace on 2021-06-25T10:16:35Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01; Eucalyptus bark is an agroindustry residue generated in large quantities due to its physical-chemical characteristics. Several industries, such as the pulp and paper industry, the timber and derived industries, do the wood separation and commonly the bark is discarded in the field or sent to companies t...

Comparação entre valores de ensaios experimentais e calculados da resistência a...

Made available in DSpace on 2018-12-11T16:56:12Z (GMT). No. of bitstreams: 0 Previous issue date: 2014-01-01; To design connections between timber parts with metal dowels (nails or bolts), two phenomena must be considered: bending of the metal dowel and the embedment strength in the wood. The Brazilian Standard ABNT NBR 7190:1997 proposes the methods used in the laboratory tests to determine the embedment stren...

Roughness study on homogeneous layer panels manufactured from treated wood waste

Natural resource exploration is growing, highlighting woods and joinery waste, wood industries and the like. This study presents homogeneous particleboard (PPH) roughness characterization manufactured from treated wood waste. Normative document with values of Brazilian Technical Standard Association ABNT NBR 8404 (1984), was adopted as a reference. The results show that the manufactured PPH showed roughness cla...

Shear and longitudinal modulus of elasticity in wood: relations based on static...

 Improve quality of timber structures design is an aim that must be systematically sought by engineers in this area. An important topic that can contribute directly to be achieved in this subject is the more consistent knowledge related to structural properties of wood. Know values of longitudinal modulus of elasticity (E) and shear modulus (G) is essential for proper evaluation of plate structures performance,...

Particleboard produced with sawmill waste of different wood species

Made available in DSpace on 2014-12-03T13:09:02Z (GMT). No. of bitstreams: 0 Previous issue date: 2014-01-01; This study aimed to investigate physical performance of particleboards produced with waste from sawmills, containing different wood species, and two adhesives: urea-formaldehyde (UF) based resin and castor-oil (PU) based bi-component polyurethane resin. Panels were produced with nominal density 0.8gcm(-...
