Physical, mechanical and hydration kinetics of particleboards manufactured with woody biomass (Cupressus lusitanica, Gmelina arborea, Tectona grandis), agricultural resources, and Tetra Pak packages

Abstract

Lignocellulosic wastes resulting from agricultural activities as well as Tetra Pak residues from urban centres can cause significant levels of pollution. A possible action to minimize this problem is to use them in the production of particleboards. The purpose of this study was to evaluate the physical, mechanical, and hydration properties of particleboards manufactured with the mixture of woody biomass (Cupressus lusitanica, Gmelina arborea, and Tectona grandis) and either agricultural wastes [pineapple leaves (Ananas comosus) and palm residues (Elaeis guineensis)] or Tetra Pak residues (TP). The results show that the particleboards prepared with TP and woody biomass can reduce the swelling and water absorption in up to 40% and 50% compared with particleboards without TP. Also, these particleboards had increased flexure resistance and shear stress (up to 100%) compared with those without TP. On the contrary, particleboards prepared with pineapple leaves in combination with woody biomass showed the lowest mechanical properties, particularly for tensile strength, hardness, glue-line shear, and nail and screw evaluation.

Pellets Evaluation Made from Tropical-Climate Agricultural and Forestry Crops of Costa Rica with a Domestic Stove

“…However, variation in Consumption pellet is affected by other characteristics of the pellets. Although in this study no physical nor chemical characteristics of the pellets were reported, in previous works these properties have been included [18][19][20] variation in length, density (of pellet and bulk density) and the dimensions of the particles forming the pellet were demonstrated. Carvalho et al [16] indicate that these pellet properties affect how they are fed into the domestic stove system when a screw feeder is employed.…”

“…Presently, the technological adaptations to the pellet production process are known for many tropical-climate agricultural crops [18], as are the evaluation of some aspects of the pellet quality and the information about the physical, chemical or energetic characterisation [19,20]. However, the behaviour of these crops in equipment such as domestic pellet stoves, regarding energy efficiency and level of emissions are scarcely known.…”

“…In Costa Rica, as well as in other Latin American countries, pellets have become popular as some industries aim towards converting from fossil-fuel based heat production to one derived from renewable sources as a means to achieve carbon neutrality [18]. Presently, the technological adaptations to the pellet production process are known for many tropical-climate agricultural crops [18], as are the evaluation of some aspects of the pellet quality and the information about the physical, chemical or energetic characterisation [19,20].…”

Novel composite sandwich structure from green materials: Mechanical, physical, and biological evaluation

“…[16][17][18][19][20][21][22] The aim of this study is to develop and evaluate a novel sandwich structure ( Figure 1) using a lightweight and relatively thick core materials in form of particleboard panels from local and cheap lignocellulosic resources attaching to two thin, and stiff woven fabric skins using VARTM technique to construct high performance structure for use in various technical applications. Huge efforts are being intensified to elaborate their applications.…”

Interfacial separation and characterization of Al–PE composites during delamination of post‐consumer Tetra Pak materials

“…Recovery of this form of post‐consumer packaging is more difficult than that of traditional packaging made of a single material, so in past decades the majority of this waste packaging was burned or dumped as landfill, causing environmental pollution and waste of resources . Today, owing to the lack of material such as wood, oil and non‐ferrous metal resources, post‐consumed paper/Al foil/PE composites have higher recycling value …”
