Commercial and environmental benefits have made carbon dioxide (CO2) methanation one of the topmost research projects all over world both at pilot plant commercial scale. Mitigation CO2 via capture storage (CCS) routes less motivation from a point view. Therefore, an integrated system is paramount importance to convert into value-added products such as methane (CH4) using solar energy (photosynthesis) or surplus electrical in hydrolysis for production reactant hydrogen use methanation. To...

Porous ZnO/cellulose nanofiber (CNF) composites were synthesized to investigate their photocatalytic degradation of methylene blue (MB) dye (a persistent organic pollutant model) under a UV lamp and sunlight. UV/vis analysis indicated that complete photodegradation was achieved in about 10 min natural sunlight with low intensity (between 1500 2900 μW/cm–1 UVA/B). Scanning electron microscopy, Fourier transform infrared, Brunauer–Emmett–Teller, X-ray diffraction, small-angle scattering...

Abstract Objectives To deveop on-pack visual indicators for the real-time monitoring of raw beef steaks in a modified atmospheric packaging (MAP). Materials and Methods Three were prepared by spray deposition nanocellulose suspension (1.5%, mass) with desired concentration pH-sensitive indicators, either red cabbage (RC) extract, black carrot (BC) or chlorophenol (CPR). The responsiveness colorimetric pH assessed visually CIE-Lab quantitative analysis, to freshness stored under MAP...

Abstract Nanocellulose (NC) films are gaining popularity in recent years owing to their recyclability and biodegradability; however, the commercialization of this material is limited by environmental moisture barrier constraints. The incorporation carboxymethyl cellulose (CMC) with NC significantly improved performance but resultant were quite hydrophilic hence completely disintegrated water. aim study produce hydrophobic NC/CMC without compromising characteristics. For purpose, optimized...

Abstract Synthetic packaging has excellent performance, but most of them becomes a waste after their use and thus, poses serious concerns to the environment consumer health. Considering current circumstances, demand for sustainable that is either recyclable or biodegradable if discarded increased tremendously in last few years. Cellulose nanofibril (CNF) films are emerging as packaging; however, high energy consumption associated with production fibres reduced properties on recycling...

Concerns over water contamination by biorecalcitrant, persistent organic pollutants have emphasized the need for effective, cheap, and scalable treatment methods. Photocatalysis offers potential advantages of using air as oxidant, ambient conditions reaction, sunlight source energy; however, identifying a sustainable catalyst support sunlight-active, earth-abundant photocatalysts is challenging. This study demonstrates first time development ZnO/cellulose nanofiber (CNF) continuous flow...

Abstract In this work, we produced composites of mesoporous silica synthesized in-situ on never-dried bleached eucalyptus kraft pulp fibers with the aim providing cost-effective depth filters, having high flux, and adsorptivity. The loading for samples was in range 12–35 wt%. performance double-layer membranes studied adsorption charged molecules. best nanofibrillated cellulose-pulp-mesoporous membrane adsorbed 1160 mg/m 2 methylene blue had a flux 10 L m −2 h −1 bar . cellulose layer...

Abstract The pulp and paper industry is one of the most significant industrial water polluters, generating large volumes wastewater with high levels organic pollutants, suspended solids, other contaminants. Catalytic ozonation has emerged as a promising technique for treatment wastewater. Numerous reviews have presented research on catalytic ozonation; however, open literature missing bibliometric analysis. Therefore, this article presents analysis available in treatment. A total 578...

At present, global warming and climate change are the major challenges of foremost significance that substantially influence earth's environment. The construction sector, especially buildings, is one largest sources greenhouse gas emissions. Conventional building materials such as clay bricks cement considered environmentally unfriendly due to enormous emissions during their production. This paper investigates utilisation used engine oil (UEO) an alternative usual cementitious binders....

Conventional roofing tiles, composed of either clay or concrete, are considered as environmentally unfriendly since a substantial quantity greenhouse gases is being discharged in their production. In this study, an alternate approach utilizing vegetable oil proposed to produce tiles called ‘green tiles’. It believed that extended heat curing may convert into rigid binder after undergoing series complex autocatalytic oxy-polymerization reactions. These green have flexural strength up...

This paper presents a research study conducted on the usage of vegetable oil for production eco-friendly Vege roofing tiles. Conventional tiles which constitute concrete and clay are considered as environmentally unfriendly because significant amount greenhouse gas emission during their production. An entirely novel methodology utilizing catalyzed is proposed can totally replace use traditional binders like cement clay. Limited trails prototypes samples revealed that when mixed with...
