Book entitled, ”Nanocellulose from Techno-economic Perspective”

(published in March 2022, www.nanoindustry.in; info@nanoindustry.in)

ISBN No.: 978-81-923542-7-9; Author- Dr Mahendra Patel; Pages- 560, Published by Industrypaper in March, 2022; Foreword by Dr. Daven Chamberlain, Editor, Paper Technology International, PITA, United Kingdom.

Nanocellulose is gradually gaining prominence because of its property-enhancing ability as a super additive in a large number of products; notably paper and packaging, food, medicine, composite materials, cosmetics, textile, energy and electronics and in many other materials. Nanocellulose-based composite materials find applications in the medical for artificial organs etc., as nanocellulose is biocompatible. The possibility of its use as antimicrobial material to combat the Corona virus has recently been advocated and if the technology can be advanced, it will be of immense service to the society.

This book addresses the techno-economic aspects of nanocellulose production. Raw materials account for 40-70% of the total cost of nanocellulose production at industrial scale and thus governs the techno-economics. This book discusses on the vital issue of techno-economics starting from the individual raw material to processing technologies, giving flow diagrams/case study and product SEM/TEM/AFM micrographs; XRD and particle size etc.

There are as such more than forty different raw materials discussed in this book, apart from different trees and industrial as well as agricultural wastes, produced in small volumes. The papermaking fibres, namely wood, agro-residues and recycled fibre are discussed elaborately in one section, considering the techno-economic implications of the papermaking fibres in nanocellulose production at industrial scale. Few modifications in the present manufacturing process, are suggested for higher yield and uniform quality of nanocellulose. The raw materials are discussed in the six different sections and 22 chapters.

Photocatalyst for antiviral coating against COVID variants

In a research work, from Tokyo Institute of Technology, a photocatalyst has been developed which can act effectively against the Covid variants. The photocatalyst is made using a combination of titanium dioxide (TiO2) and copper oxide (CuxO) nanoclusters inactivates various variant types of novel coronavirus SARS-CoV-2.

By coating the CuxO/TiO2 powder on a glass, the team showed that it could inactivate even the highly virulent Delta variant of SARS-CoV-2. The team has also confirmed the inactivation of Alpha, Beta, and Gamma variants by CuxO/TiO2 in addition to the wild type strain.

Resolving nanostructures smaller than the diffraction limit of light

Jet fuel has been produced from lignin from agricultural waste. According to the results obtained, this sustainable fuel could be mixed with other biofuels to fully replace petroleum-derived fuels. Such sustainable fuel could help the aviation industry reduce dependence on increasingly expensive fossil fuels while meeting higher environmental standards.

Drinking water from seawater

Scientists from MIT (Massachusetts Institute of Technology) in USA have developed a portable desalination unit that can automatically remove particles and salts simultaneously to generate drinking water. The unit has the ideal combination of ICP (Ion concentration polarization) and electro dialysis modules. The optimal setup includes a two-stage ICP process, with water flowing through six modules in the first stage then through three in the second stage, followed by a single electro dialysis process. This minimized energy usage while ensuring the process remains self-cleaning. The resulting water exceeded World Health Organization quality guidelines, and the unit reduced the amount of suspended solids by at least a factor of 10. Their prototype generates drinking water at a rate of 0.3 litres per hour, and requires only 20 watts of power per litre.

20-storey Wooden building in Sweden

The Sara Cultural Centre in Swedish town of Skelleftea is one of the world's tallest timber buildings, made primarily from spruce and towering 75 meters (246 feet). The 20-storey timber structure, which houses a hotel, a library, an exhibition hall and theatre stages, opened at the end of 2021 in the northern town of 35,000 people.

The main advantage of working with wood is that it is more environmentally friendly. Cement, used to make concrete and steel, two of the most common construction materials, are among the most polluting industries because they emit huge amounts of carbon dioxide, a major greenhouse gas but wood emits little CO2 during its production and retains the carbon absorbed by the tree even when it is cut and used in a building structure. It is also lighter in weight, requiring less of a foundation. Wood as a construction material can be up to 30 times less carbon intensive than concrete and thousand times less than steel.

Bacterial nanocellulose enables auxetic supporting implants

Owing to its purity and exceptional mechanical performance, bacterial nanocellulose (BNC) is well suited for tissue engineering applications. The development of complex 3D forms is shown by taking advantage of the aerobic process involved in the biogenesis of BNC at the air/culture medium interphase. Hence, solid supports are used to guide the formation of BNC biofilms that easily form auxetic structures. The term auxetic refers to materials with negative Poisson's ratio, which counterintuitively expand in a direction normal to that of the tension or load. Such biomaterials are demonstrated as implantable meshes with prescribed opening size and infill density. The measured mechanical strength is easily adjustable (48–456 MPa tensile strength) while ensuring shape stability (>87% shape retention after 100 burst loading/unloading cycles).
