Agriculture waste has attracted attention as a potential source to produce raw material silicon dioxide, either crystalline (pyrophyllite) or amorphous form (geothermal sludge). It is an unwanted waste produced as a desired result of agricultural activities. Nanosilicon dioxide has undoubtedly gained eager interest in many vital industries. It is renowned for positively enhancing outstanding performance due to tuneable properties over its bulk counterpart. Silicon dioxide scientifically demonstrates a unique ability to convert efficiently into economic value from silicon-rich agriculture waste. Thus, a noble extraction from silicon-rich waste is undoubtedly gaining enormous attention. However, adequate knowledge on local optimisation of nanosilicon dioxide extraction from silicon-rich agriculture waste is lacking. Specific aims of this comprehensive review mainly highlighted a synthesis method of potential nanostructured silicon dioxide from agriculture waste and their potential applications for plant growth promoters. Reverse microemulsion, chemical vapour condensation, solid gelation, and mechanochemical are preferred methods that were typically specified to focus this comprehensive review critically. Optimisation of nanosilicon dioxide can be achieved precisely via the ideal combination of solid gelation and a high-energy ball mill process. Silicon dioxide is undoubtedly an effective agent as a plant growth promoter to overcome biotic and abiotic factors such as heavy metal uptake and translocation, inhibit pathogenic fungi, improve the antioxidant system, and mitigate various stress factors.

“…However, nano-silica has the characteristics of a large specific surface area, low toxicity, good optical transparency, excellent biological compatibility, and easy functional modification. It not only shows the small size effect, macro quantum effect and surface effect of general nano-materials, it also has unique physical and chemical properties such as photoelectric properties, a high magnetoresistance phenomenon, and nonlinear resistance [10,11]. It was widely used in the fields of material adsorption and separation, electronic packaging materials, nano-biomedicine, antimicrobial materials, catalysis, and drug carriers [12,13], which made use of the chlorosilane residue liquid to prepare nano-silica showing a high value and unique advantages in terms of resource utilization and environmental protection.…”

In this paper, nano-silica particles were prepared from chlorosilane residue liquid using an inverse micro-emulsions system formed from octylphenyl polyoxyethylene ether (TX-100)/n-hexanol/cyclohexane/ammonia. The influence of different reaction conditions on the morphology, particle size, and dispersion of nano-silica particles was investigated via single-factor analysis. When the concentration of chlorosilane residue liquid (0.08 mol/L), hydrophile-lipophilic-balance (HLB) values (10.50), and the concentration of ammonia (0.58 mol/L) were under suitable conditions, the nano-silica particles had a more uniform morphology, smaller particle size, and better dispersion, while the size of the nano-silica particles gradually increased with the increase in the molar ratio of water to surfactant (ω). The prepared nano-silica was characterized through XRD, FT-IR, N2 adsorption/desorption experiments, and TG-DSC analysis. The results showed that the prepared nano-silica was amorphous mesoporous silica, and that the BET specific surface area was 850.5 m2/g. It also had good thermal stability. When the temperature exceeded 1140 °C, the nano-silica underwent a phase transition from an amorphous form to crystalline. This method not only promoted the sustainable development of the polysilicon industry, it also provided new ideas for the protection of the ecological environment, the preparation of environmental functional materials, and the recycling of resources and energy.

“…Silicates are usually produced from mineral deposits; however, methods of extraction of pure compounds are often quite expensive and energy consuming. As an alternative source of raw materials, the large scale industrial waste containing a large amount of silicon could be used, as well as renewable plant waste from the processing of agricultural products (Singh et al 2020;Goodman 2020). Involvement of huge volumes of waste of agricultural crops of annual plants and waste generated during the technogenic processing of mineral resources into recycling is an urgent task of modern industry and environmental safety (Kumar et al 2016;Yarusova et al 2017).…”

The production waste involvement in processing and recycling-one of the urgent tasks in the development of environmentally oriented and resource-saving technologies. In this work, two types of silicate-containing materials of plant (silicon dioxide from rice husk) and technogenic (calcium hydrosilicate) origin are studied as sorbents for removal of heterotrophic bacteria from water and as fillers for eco-friendly marine antifouling coatings. Characterizations (morphology, chemical composition, specific surface area, zeta-potential), bacterial adsorption performance and prepared samples efficiency in antifouling coating were investigated. The results showed that the sample of calcium hydrosilicate obtained from technogenic raw materials has a macroporous needle-like structure and characterized by high removal efficiency to Escherichia coli and Bacillus subtilis in 0,05 M NaCl. Sample of biogenic silicon dioxide characterized by globular micromorphology with high value of specific surface area. Incorporation of inorganic filler particles of biogenic and technogenic samples in the coating enhanced the paint hardness. Improved antifouling performance was shown for coatings with SiO 2 from rice husk coupled with bacterial antifouling extract during 9 months of field test.
