Cellulosic fiber (CF) in nanoform is emergingly finding its way for COVID-19 solution for instance via nanocomposite/ nanoparticle from various abundant biopolymeric waste materials, which may not be widely commercialized when the pandemic strikes recently. The possibility is wide open but needs proper collection of knowledge and research data. Thus, this article firstly reviews CF produced from various lignocellulosic or biomass feedstocks' pretreatment methods in various nanoforms or nanocomposites, also serving together with metal oxide (MeO) antimicrobial agents having certain analytical reporting. CF-MeO hybrid product can be a great option for COVID-19 antimicrobial resistant environment to be proposed considering the long-established CF and MeO laboratory investigations. Secondly, a preliminary pH investigation of 7 to 12 on zinc oxide synthesis discussing on Fouriertransform infrared spectroscopy (FTIR) functional groups and scanning electron microscope (SEM) images are also presented, justifying the knowledge requirement for future stable nanocomposite formulation. In addition to that, recent precursors suitable for zinc oxide nanoparticle synthesis with emergingly prediction to serve as COVID-19 purposes via different products, aligning with CFs or nanocellulose for industrial applications are also reviewed.

The large amount of biomass waste generated by vineyard pruning causes many environmental concerns. The production of briquettes represents an alternative to obtaining a value-added product. The transformation of vineyard wastes into briquettes could produce a densified product having high energy potential. The study investigates the production and chemical, structural, and thermal characterization of briquettes. The thermogravimetric analysis (TGA) shows that the briquettes have different stages of decomposition depending on temperature, such as drying, heating, devolatilization, and char aggregation. All the briquettes are decomposed around 600 °C. The analysis by X-Ray diffraction (XRD) shows the crystallinity of briquettes. The pollutant emissions resulted from briquettes burning were measured as 444.7 mg N−1m−1 nitrogen oxide (NOX), 157.0 mg N−1m−1 sulphur dioxide (SO2) and 2165.0 mg N−1m−1 carbon monoxide (CO). The flue gases are below the admitted limits, with the exception of carbon monoxide content due to the incomplete combustion and high lignin content. Therefore, it can be concluded that briquettes produced from vineyard wastes have similar properties to briquettes produced from wood. This study demonstrates the potential of the obtained briquettes to replace the wood or charcoal through a desulphurization method.
