“…From the Figure 5 , The Jute-PLA and SHS-Jute-PLA biocomposites showed two distinctive XRD patterns at almost 2θ ≈ 16.8° and 2θ ≈ 22°; these peaks are aligned with the unique reflections of the cellulose 1 crystalline polymorph, related observations reported by Sena Neto [ 43 ] and Jalil et al. [ 47 ]. The existence of these two distinctive peaks can be ascribed to the presence of jute and PLA in the composite.…”

This report describes the case of pineapple residues as potential feedstock for new carbon-based materials, especially the use of pineapple leaf fiber (PALF) in textiles. Currently, pineapple crop residues are an environmental burden and their discharge an important cost for the pineapple industry in many tropical countries. The use of pineapple residues as feedstock for biomaterials could create potentially a win-win situation: The pineapple industry can add value to crop residues that are currently a costly waste, while the residues provide a valuable feedstock for various biomaterials contributing to the bioeconomy.Using Costa Rica as a case study, the objectives of this study were to:1. Identify pineapple residue valorization options with a focus on the characteristics of PALF for textiles.2. Estimate the amount of pineapple residues potentially available for PALF.3. Better understand the agronomic, technical, economic, social-institutional bottlenecks hampering the transition towards a biomaterial transition.4. Identify follow-up R&D tracks to deal with the identified bottlenecks with focus on the total use of pineapple residues. This study identifies five major application domains for pineapple residues, i.e., fibers (including PALF for textile), chemical compounds, animal feed, substrate, and energy. Because only 10-20% of the dry matter of the pineapple leaves consists of PALF the remaining residual biomass will also have to find an application (in the bioeconomy) for enhancing the economic viability and optimizing the sustainable use of PALF in the textile and apparel industry. Cascading of different valorization options may increase the resource use efficiency and the economic value of the pineapple residues.Current management costs of pineapple residues in Costa Rica varies between 32 and 81 USD/ton dry matter. The amounts of crop residues and PALF that each year come available after the second harvest of pineapples in Costa Rica are large enough for scalable solutions. We estimate that annually ≈ 620,000 t dry matter of crop residues is available for valorization options, which contains about 45,800 and 91,600 t PALF per year. At the same time, biogas (LPG) can be generated from the crop residues in an amount sufficient to meet about 13% of the national LPG requirements per year, which is currently based for 100% on imports.Despite the large amount of biomass available and the need for more environmental-friendly ways to dispose pineapple residues up to date there are no large-scale initiatives to bring any of the identified valorization options to scale in Costa Rica. There is even less attention for the cascading of different valorization options, which have the potential to reinforce the economic viability of individual valorization options. Four interrelated bottlenecks are identified that hinder valorization developments in Costa Rica: i) The failure to account for the true costs of current residue management, which slows down the industry's response to develop alternative ways to dispose the res...

“…Then the sun-dried, sticky PALF is chemically degummed to remove the non-cellulosic elements. [5][6][7] Alkalization is the most common chemical treatment used for removing the hemicellulose and lignin as well as other non-cellulosic constituents, which are the most hydrophilic parts of ligno-cellulosic fibres. 7,8 Alkali and acid treatments are simple and cost-effective, but not eco-friendly.…”

This work investigates the potential utilisation of the agro-waste pineapple leaf fibre (PALF) as a green reinforcement in polypropylene (PP) composites. Generally, chemical treatment is used to clean the scratched PALF, and the effluents of those chemicals are discharged into nature. A new mechanical approach (carding) was used in this work to remove the remaining extraneous substances from the scratched and sun-dried PALF instead of using any chemical treatment. The percentage of sticky fibres and dust content decreased, and fibre breakage increased with the increasing number of carding passages. The individualized fibre properties were also influenced by the number of carding passages. The carding process reduced the diameter of PALF due to removal of extraneous materials. The tensile properties of raw PALF improved significantly until the fourth carding passage and further increase in the number of passages did not show any significant influence on the tenacity and modulus. Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) confirmed the elimination of hemicellulose along with other gummy and waxy substances from the individualized PALF due to the carding action. The crystallinity % also increased after the carding process due to the removal of amorphous substances. As the reinforcement-matrix interfacial shear strength (IFSS) strongly influences the physico-mechanical properties of composites, IFSS of carded PALF reinforced finer and coarser PP fibre micro-bonded composites was also studied using the single fibre pull-out test (SFPT). Among different composites, the fourth carding passed PALF-reinforced finer PP fibre micro-bonded composite showed the highest IFSS. Additionally, the load- extension curves and SEM images of the tensile pulled-out surface were investigated to study the interfacial adhesion between PALF and PP micro-droplets. The increased surface roughness of PALF due to the carding action resulted in an improvement in the IFSS of PALF-reinforced PP micro-bonded composites.
