“…3) (Xiong et al 2018). The physicochemical interactions among cellulose, hemicellulose, and lignin are responsible for shielding the cellulose from isolation (Hassan et al 2020;Zhong et al 2020). The multistage procedure for the isolation of cellulose nanoparticles from biomass is acquired in two steps.…”

Renewable cellulosic nanocomposites for food packaging to avoid fossil fuel plastic pollution: a review

The extensive use of petroleum-based synthetic and non-biodegradable materials for packaging applications has caused severe environmental damage. The rising demand for sustainable packaging materials has encouraged scientists to explore abundant unconventional materials. For instance, cellulose, extracted from lignocellulosic biomass, has gained attention owing to its ecological and biodegradable nature. This article reviews the extraction of cellulose nanoparticles from conventional and non-conventional lignocellulosic biomass, and the preparation of cellulosic nanocomposites for food packaging. Cellulosic nanocomposites exhibit exceptional mechanical, biodegradation, optical and barrier properties, which are attributed to the nanoscale structure and the high specific surface area, of 533 m2 g−1, of cellulose. The mechanical properties of composites improve with the content of cellulose nanoparticles, yet an excessive amount induces agglomeration and, in turn, poor mechanical properties. Addition of cellulose nanoparticles increases tensile properties by about 42%. Barrier properties of the composites are reinforced by cellulose nanoparticles; for instance, the water vapor permeability decreased by 28% in the presence of 5 wt% cellulose nanoparticles. Moreover, 1 wt% addition of filler decreased the oxygen transmission rate by 21%. We also discuss the eco-design process, designing principles and challenges.

“…Consequently, applying microwaves causes reducing in the equipment size and processing time. Therefore, microwave heating is now not only applied for industrial wood drying, food processing, and rubber vulcanization, but also studied in various areas, such as, ceramic and polymer processing (Komarneni et al 1992;Hoogenboom and Schubert 2007;Wiesbrock et al 2004), environmental applications (Jones et al 2002a, b;Verma and Samanta 2018;Zhang and Hayward 2006;Zlotorzynski 1995), biofuels and chemical productions (Aravind et al 2020;Hassan et al 2020), and metallurgy and mineral processing (Jones et al 2002a, b;Kingman et al 2004). Particularly, there is an increasing interest in the study of heterogeneous gas-phase catalysis under microwave heating (Zhang and Hayward 2006;Durka et al 2009), such as NH 3 decomposition (Guler et al 2017), CH 4 decomposition (Domínguez et al 2007a, b;Zhang et al 2003), H 2 S decomposition (Xu et al 2017a, b), NO x and SO 2 reduction (Peng et al 2017;Zhang et al 2001), CO 2 reforming of CH 4 (Fidalgo and Menéndez 2013;Lim and Chun 2017;Zhang et al 2003) and recently steam reforming of alcohols (Durka et al 2011;Gündüz and Dogu 2015;Sarıyer et al 2019).…”

“…In heterogeneous catalysis systems, carbon-containing materials, i.e. carbon blacks, activated carbon and chars from biomass residues, are widely evaluated as support or as catalyst in reactions due to their thermal durability, availability, great porosity, low cost and oxygen surface groups improving the catalytic performance and product selectivities (Rodriguez-Reinoso 1998; Titirici et al 2015;Balajii and Niju 2019;Hassan et al 2020). Particularly, in comparison with metalbased catalysts, carbon-based catalysts possess excellent ability in microwave absorption, known as good microwave receptors appropriate for microwave-assisted DRM (Fidalgo et al 2010;Li et al 2017).…”

Abatement of emissions of greenhouse gases such as methane and carbon dioxide is crucial to reduce global warming. For that, dry reforming of methane allows to convert methane and carbon dioxide into useful synthesis gas, named 'syngas', a gas mixture rich in hydrogen and carbon monoxide. However, this process requires high temperatures of about 900 °C to activate methane and carbon dioxide because dry reforming of methane reaction is highly endothermic. Therefore, a solid catalyst with appropriate thermal properties is needed for the reaction. As a consequence, efficient heating of the reactor is required to control heat transfer and optimize energy consumption. Microwave-assisted dry reforming of methane thus appears as a promising alternative to conventional heating. Here we review the recent research on microwave-assisted dry reforming of methane. We present thermodynamical aspects of the dry reforming of methane, and basics of microwave heating and apparatus. We analyse reformers that use microwave heating. Catalysts used in a microwave-assisted reformer are presented and compared with reactors using conventional heating. Finally, the energy balance is discussed.

“…Identifying sources of biofuels such as biodiesel and biochar can potentially reduce the environmental impacts of fossil fuels (Balajii and Niju 2019;Gunarathne et al 2019). Biofuels can also counter the increasing use of fossil resources and prevent pressure on non-renewable sources (Peng et al 2020;Hassan et al 2020). However, it is important to use practical, scientific and robust tools to evaluate the real benefits of using biofuels over conventional energy sources (Chamkalani et al 2020;Kargbo et al 2021).…”

Conversion of biomass to biofuels and life cycle assessment: a review

et al. 2021

The global energy demand is projected to rise by almost 28% by 2040 compared to current levels. Biomass is a promising energy source for producing either solid or liquid fuels. Biofuels are alternatives to fossil fuels to reduce anthropogenic greenhouse gas emissions. Nonetheless, policy decisions for biofuels should be based on evidence that biofuels are produced in a sustainable manner. To this end, life cycle assessment (LCA) provides information on environmental impacts associated with biofuel production chains. Here, we review advances in biomass conversion to biofuels and their environmental impact by life cycle assessment. Processes are gasification, combustion, pyrolysis, enzymatic hydrolysis routes and fermentation. Thermochemical processes are classified into low temperature, below 300 °C, and high temperature, higher than 300 °C, i.e. gasification, combustion and pyrolysis. Pyrolysis is promising because it operates at a relatively lower temperature of up to 500 °C, compared to gasification, which operates at 800–1300 °C. We focus on 1) the drawbacks and advantages of the thermochemical and biochemical conversion routes of biomass into various fuels and the possibility of integrating these routes for better process efficiency; 2) methodological approaches and key findings from 40 LCA studies on biomass to biofuel conversion pathways published from 2019 to 2021; and 3) bibliometric trends and knowledge gaps in biomass conversion into biofuels using thermochemical and biochemical routes. The integration of hydrothermal and biochemical routes is promising for the circular economy.
