... Several recent studies have been carried out on the pyrolysis of waste tyres all over the world [15][16][17][18][19][20][21][22]. However, many of these studies have focused on quantifying and characterizing the liquid yield of the pyrolytic processes, while very few have attempted to describe and enhance the efficiency of the gas production process. ...

... Among the several methods, photocatalysis is one that makes use of chemical reactions that are exposed to light at the right wavelengths and with the right catalysts (such as metal ions or metal oxide semiconductors). There are numerous study reports with different kinds of metal-organic frameworks for use in energy and environmental applications [2,18,38,47,56]. ...

... This applies to the hydrogen and oxygen obtained from electrolysis and the gas produced during pyrolysis. However, the gas obtained in the wheat straw pyrolysis experiments may prove difficult to store [42] due to the composition of the cooled gas, which contains unnecessary carbon dioxide, low-energy carbon monoxide, methane, and hydrogen. These components are challenging to store in tanks. ...

... In AD biogas technology, organic wastes are decomposed in a closed vessel or compartment by different microbial consortium in oxygen free environment which produces biogas and digestate slurry which can be used as energy source and organic fertilizer respectively [2]. Biogas generally consists of 50-70% CH4, 30-40% carbon dioxide (CO2), and other trace gases including hydrogen sulfide (H2S) however biogas composition varies depending on which substrates are being used [3]. AD process is accomplished with four steps of organic waste degradation and byproduct utilization viz. ...

... Gas sensors in thermal processes are available at temperatures up to 1000 • C, collaborating with K-type thermocouples inside the reactors, as in pyrolysis or gasification processes, which is important to determine some gases according to temperature with good stability over a long time and to selectivity detect methane, hydrogen, and carbon monoxide. However, the highest temperature remains a problem for their lifetimes, which needs to be solved by researchers and which is contoured with modulated gas multi-sensor arrays where artificial intelligence can be used to reduce noise [127]. ...

... Implementing environmentally friendlier practices that pose fewer public health risks is needed 12 . Indeed, many plants' secondary metabolites are known to have various activities against insects and are formulated as botanical pesticides to prevent crop and stored product damage. ...

... [19] In addition, novel multidimensional nanomaterials, such as carbon nanotubes and graphene, are also regarded as good thermally conductive fillers. [20][21][22][23][24] Due to its good thermal conductivity, boron nitride (hBN) is often used as a thermal filler to improve the thermal conductivity of polymers and composite materials. [25] The materials prepared in these ways still have defects such as complex process and high cost. ...

... The large amounts of organic contaminants [1,2] are a constant challenge for human health [3], water resources, reuse, and environmental issues [4,5]. Organic dyes are widely released from leather manufacturing, pulp engineering, and paper or printing [6,7]. ...

... For this reason, reliable, clean, sustainable, and renewable energy sources are sought after [10]. Hydrogen energy has become quite remarkable in this respect [11,12], as it has a series of key benefits such as: (i) when used as an energy source, it does not produce greenhouse emissions (clean burning) and has a high energy density [13]; (ii) can be used as raw material for the production of other gases and liquid fuels; (iii) it is an abundant resource and can be considered as a virtually inexhaustible energy source; (iv) can be produced locally (reducing the dependence on energy sources from unstable countries) and at different scales (small to large). Although it has great potential, as with every technology, it also has a series of disadvantages. ...

... Bacterial diseases that pollute or change water supplies are one of the biggest concerns now confronting the food industry [30]. CuNPs are thus anticipated to provide a highly efficient and long-lasting solution when used as an antibacterial and dye-removal agent [31]. Many biologically active compounds in plant-based materials, like phenolic acids, sugars, proteins, terpenoids, and polyphenols, may lower metal ions to make nanoparticles. ...
