“…This was shown by Teles et al. 30 where their Weibull statistical analysis revealed a mathematical hyperbolic type of inverse relationship between the pineapple leaf fibres tensile strength and its fibre diameter. In their study, they have used pineapple leaf fibres with a fibre length of 10 cm.…”

Rule of mixture models are usually used in the tensile properties prediction of polymer composites reinforced with synthetic fibres. They are less utilized for natural fibre/polymer composites due to natural fibres physical and mechanical properties variability which reduces rule of mixture model's prediction values accuracy compared to the experimental values. This had led to studies conducted by various researchers to improve the existing rule of mixture models to give a better reflection of the true natural fibres properties and enhance the rule of mixture models prediction accuracy. In this paper, rule of mixture model's utilization includes the existing rule of mixture models as well as proposed rule of mixture models which have one or more factors incorporated into existing rule of mixture models for natural fibre/polymer composites tensile properties prediction are reviewed.

Recent Advances in Natural Fibre-Based Materials for Food Packaging Applications

Packaging is one of the major domains in the food processing industry that reduces waste and enhances product shelf life. Recently, research and development have focused on bioplastics and bioresources to combat environmental issues caused by the alarming growth of single-use plastic waste food packaging. The demand for natural fibres has recently increased because of their low cost, biodegradability and eco-friendliness. This article reviewed recent developments in natural fibre-based food packaging materials. The first part discusses the introduction of natural fibres in food packaging, with a focus on fibre source, composition and selection parameters, while the second part investigates the physical and chemical ways to modify natural fibres. Several plant-derived fibre materials have been utilised in food packaging as reinforcements, fillers and packaging matrices. Recent investigations developed and modified natural fibre (physical and chemical treatments) into packaging using casting, melt mixing, hot pressing, compression moulding, injection moulding, etc. These techniques majorly improved the strength of bio-based packaging for commercialisation. This review also identified the main research bottlenecks and future study areas were suggested.

“…Compared to flax and jute, PALF seems to have similar strength, modulus and elongation properties. The properties presented in Table 5 are indicative: Strength depends on fiber diameter (e.g., Teles, 2015;Mukherjee, 1986) and on span length and strain rate (e.g., Mukherjee, 1986), however, the majority of the research papers does not relate PALF strength properties to diameter nor testing conditions.…”

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...
