“…The use of agave fibres in a polystyrene matrix have shown an increase in the tensile strength up to 25% for a 20% composite, while higher ratios of fibres implies a reduction in mechanical properties [40]. Singha and collaborators [37] found an increase in mechanical properties, mainly in impact behaviour, for composites up to 30% of agave fibres, also using polystyrene as matrix; they have also demonstrated that the size of the is an important factor to take into account.…”

Characterization of Agave americana L. plant as potential source of fibres for composites obtaining

This paper summarises the results obtained from the characterization assays from century plant (Agave americana L.), determining the chemical composition of different parts of the plant. Fibres were obtained by means of a mechanical device, specifically designed and built for Agave americana leaves processing. Obtained fibres were subjected to thermogravimetric analysis and infrared spectra, and their chemical composition was also determined by quantitative acid hydrolysis. Once obtained, fibres were blended up to 40% (in weight) to obtain composites by compression moulding, using polyethylene as matrix; mechanical testing show improvements in elastic modulus for both tensile and flexural tests; increase in flexural maximum strength were also found for the composites, while tensile strength is slightly reduced with the introduction of agave fibres. The research is part of a project developed in the Macaronesian region, which aim is to demonstrate the feasibility of using biomass from invasive plant species in the composites sector as a way of financing control campaigns and habitats conservation labours, which is the main novelty of this research.

In recent years, Agave has shown its potential as a bioenergy feedstock with a higher land productivity (up to 42 ton/ha year) than traditional feedstocks. Other features are its adaptation mechanism to high temperatures and its resistance to drought. The agronomics of Agave in Mexico are discussed, including total land planted, inputs required, and the harvesting and transport costs. Heating values, mineral concentration, and carbohydrate and lignin content show the potential of the Agave species to compete with current bioenergy crops. Currently, the pre-treatment of Agave is the most widely studied stage in biofuels and value-added products, which include technologies capable of reducing its recalcitrance while removing xylan and/or lignin and reducing cellulose crystallinity, among other effects, to increase the overall yield in saccharifi cation and fermentation, which will be discussed as well. In addition to spirits and fi bers from industrial interests, different liquid (ethanol and n-butanol) and gaseous (methane and hydrogen) biofuels, including certain value-added products (enzymes, lactic acid, and succinic acid), can be obtained from Agave in high yields. The main objective of this review is to address the recent advances in the utilization of Agave as a bioenergy feedstock for biofuels and value-added products within a sustainable biorefi nery scheme.

“…[10] In addition, acetic acid has drawn particular attention because of its ability to achieve extensive and selective delignification in a single-step operation.- [11] In organosolv delignification, both lignin and hemicelluloses are attacked, leading to the formation of oligomers and the dissolution of a large proportion of these components to be further purified. [12] There has been no reported study on the utilisation of CS as a renewable cellulose source along with a full characterisation of the extracted cellulose. Therefore, the objective of this work was to investigate different cellulose isolation and purification procedures from CS, including treatments by chemicals like HP, alkaline, methanol, ethanol, acetic acid, and their combinations.…”

Several methods for the isolation and purification of cellulose from coffee silverskin (CS) were investigated using alkaline, hydrogen peroxide (HP), organosolvents, acetic acid, and their combinations. The process and cellulose were characterised by their yield, cellulose content, colour, alkaline resistance (R 10), FTIR spectroscopy, X-ray diffractometry, and thermal stability. Whiteness index (WI), R 10 , crystallinity, thermal stability, yield, and cellulose content of the solids obtained after extraction were dependent on the extraction procedures. Alkaline ethanol-HP-acetic acid protocol resulted in a cellulosic sample with the highest thermal stability (13% weight loss (WL) in the temperature range of 280-360°C) and a cellulose I β content with 70% crystallinity. These results showed the great potential of CS as a new source of cellulose.
