The aim of this paper is to utilize coal fly ash and waste paper which are currently causing disposal problems, for the production of lightweight materials which might find application in construction industry. The view is to investigate the effects of waste-paper to fly ash ratio on the properties of lightweight, high strength geopolymeric materials produced from these wastes. The results of this study show that decreases in weight, compressive strength and tensile strength as the waste paper content increases. It can be shown that with up to 50% decrease in weight of geopolymeric material with a comparative compressive strength of 4.51 MPa, similar to commercially available construction materials can be achieved by using 20% waste paper with coal fly ash. The capillary water absorption revealed that the material absorbs water at a fast rate suggesting its suitability for indoor applications. The results of this study would provide an alternative and cost-effective approach to manufacturing of non-load bearing construction materials from waste.

The development of bio-insultation materials has attracted increasing attention in building energy-saving fields. In tropical and hot–humid climates, building envelope insulation is important for an energy efficient and comfortable indoor environment. In this study, several experiments were carried out on a bio-insulation material, which was prepared by using rice husk as a raw material. Square rice husk-based insultation panels were developed, considering the ASTM C-177 dimensions, to perform thermal conductivity coefficient tests. The thermal conductivity coefficient obtained was 0.073 W/(m K), which is in the range of conventional thermal insulators. In a second phase of this study, two experimental enclosures (chambers) were constructed, one with rice husk-based insulation panels and the second one without this insulation. The measures of the temperatures and thermal flows through the chambers were obtained with an electronic module based on the ARDUINO platform. This module consisted of three DS18B20 temperature sensors and four Peltier plates. Daily temperature and heat flux data were collected for the two chambers during the dry season in Panama, specifically between April and May. In the experimental chamber that did not have rice husk panel insulation on the roof, a flow of up to 28.18 W/m2 was observed, while in the chamber that did have rice husk panels, the presence of a flow toward the interior was rarely observed. The rice husk-based insulation panels showed comparable performance with conventional insulators, as a sustainable solution that takes advantage of a local resource to improve thermal comfort and the reduction of the environmental impact.

“…14 Since cellulose was first identified in plants by Anselme Payen in 1838, 15 it has been used in everyday materials, such as textile fibers (e.g., rayon) and packaging films (e.g., cellophane). 1 More recently, cellulose has been used industrially for the fabrication of paper, 16 laminates, 17 building and coating materials, 18 optical films, 19 dietary fibers, 20 and advanced reinforcement additives in polymer composites. 21,22 Cellulosic materials and their potential in a broad range of applications have been studied for more than a century.…”

Nanocelluloses, nanoscale cellulosic particles or fibrils, are an appealing class of nanomaterials with enormous potential for sustainable development. They have great promise to target some of the 17 Sustainable Development Goals outlined by the United Nations. Nanocelluloses are derived from the most abundant biopolymer in the world, cellulose, which have multiple hydroxyl groups on their surface, enabling a vast range of chemical modifications. The interplay between the chemical structure and physicochemical properties of nanocelluloses is crucial to engineering the next generation of green, functional nanomaterials. In this review paper, we provide a comprehensive account of the structure–property relationships in nanocelluloses, which may establish the basis for the design of precision bio‐based materials. Chemical modifications of nanocelluloses, including hydrolysis, oxidation, esterification, amidation, and polymer grafting, provide an array of chemical and physical properties that open opportunities in a diverse spectrum of applications. We review how chemical modifications affect the physicochemical properties of nanocelluloses, such as thermal stability, hydrophobicity, and dispersibility in nonpolar media. Understanding nanocellulose chemical structure–property relationships is integral to the development of sustainable material platforms based on the most renewable biopolymer on earth.
