Life cycle analysis of a particleboard based on cardoon and starch/chitosan
Mata, Teresa Margarida; Freitas, Clara; Silva, Gabriela Ventura; Monteiro, Sandra; Martins, Jorge Manuel; Carvalho, Luísa Hora de; Silva, Luís ManuelThis work analyzes the life cycle environmental impacts of producing a particleboard based on cardoon fibers and a starch/chitosan adhesive from a “cradle-to-gate” perspective, considering the following life cycle steps: raw material production, adhesive preparation (component mixing and heating), cardoon fiber preparation (crushing and sieving), adhesive and fiber mixing, hot-pressing and final processing. The...

Marine algal flora of São Miguel Island, Azores
Neto, Ana I.; Moreu, Ignacio; Rosas-Alquicira, Edgar; León-Cisneros, Karla; Cacabelos, Eva; Botelho, Andrea Z.; Micael, Joana; Costa, Ana C.BACKGROUND The macroalgal flora of the Island of São Miguel (eastern group of the Azores Archipelago) has attracted the interest of many researchers in the past, the first publications going back to the nineteenth century. Initial studies were mainly taxonomic, resulting in the publication of a checklist of the Azorean benthic marine algae. Later, the establishment of the University of the Azores on the Island ...
Assessment of Bending Properties of Sawn and Glulam Blackwood in Portugal
Martins, Carlos; Monteiro, Sandra; Knapic, Sofia; Dias, AlfredoPortuguese forests have changed in recent years. These changes were mainly boosted by the wildfires that a ected a significant percentage of the softwood area. Data from 2015, conveyed by the Portuguese Institute for Nature Conservation and Forests, indicates that hardwoods occupy 70% of the Portuguese forest area. This paper presents the Blackwood (Acacia melanoxylon R. Br.) species potential, focusing on cons...
Distribution of Concentrated Loads in Timber-Concrete Composite Floors: Simplif...
Monteiro, Sandra; Dias, Alfredo; Lopes, SérgioTimber-concrete composite (TCC) solutions are not a novelty. They were scientifically referred to at the beginning of the 20th century and they have proven their value in recent decades. Regarding a TCC floor at the design stage, there are some assumptions, at the standard level, concerning the action of concentrated loads which may be far from reality, specifically those associating the entire load to the beam...
Low-Density Cardoon (Cynara cardunculus L.) Particleboards Bound with Potato St...
Monteiro, Sandra; Nunes, Lina; Martins, Jorge; D. Magalhães, Fernão; Carvalho, LuísaIn the present work, and for the first time, totally biosourced low-density particleboards were produced using cardoon particles (a no added value by-product from the Portuguese cheese making industry), bound with a potato starch adhesive. Different starch/cardoon ratios (0.6, 0.8, 1 and 1.2) were tested and the effect of different bio-based additives (chitosan, wood fiber and glycerol) on the performance of th...
