“…In addition, the paddy stalks are left in the fields and destroyed by burning together with the stubble (Kıvrak & Başyiğit, 2012). The fields where the rice wastes are found have not yet entered the bioenergy and biofuel market (Kaniapan et al, 2022).…”

Today, the need for energy is increasing day by day and mankind is turning to bioenergy sources. City waste is a source of bioenergy and these wastes are not adequately marketed. The conversion of city waste into energy and marketing as biomass will contribute to keeping cities clean as a habitat. The emission standards of large cities reach dangerous levels for human health. Aware of this situation, cities are building facilities such as waste processing and waste gas. While generating energy from wastes, it is ensured that the city remains clean, and on the other hand, it contributes to meeting the energy needs of human beings. This study focuses on the conversion of city waste into energy and marketing as a source of bioenergy. Cities need to grow decently, contribute to employment and evaluate waste in the name of employment and economy for sustainable city. Bioenergy sources are increasingly important and biomass trade is being carried out that exceeds the borders of the city and country. Biomass trading is also an opportunity to evaluate vegetable wastes that have not yet gained economic value in and around the city. In this study, the literature has been examined and observations related to city wastes in Sinop province and its districts and vegetable wastes in Gökırmak and Kızılırmak deposits are included. The findings show that more research and studies should be done on bioenergy resources and that urban waste should be evaluated and marketed among biomass resources. In addition, it is suggested to dispose of plant wastes in urban areas by burning and to evaluate them as biomass instead of causing pollution in living areas.

“…It is the most important renewable feedstock (e.g., rice straw, rice husk), thus indicating considerably cheap, clean and environment-friendly (carbon-neutral) features as compared to fossil fuels such as coal [2]. As a result, there is increased interest in developing biomass-derived fuels for direct energy use [3][4][5][6][7] or converting them into higher energy density biofuels via thermochemical processes [8][9][10][11], including torrefaction [1,12,13], pyrolysis [1,14,15] and gasification [1,16,17]. Although the contents of sulfur and ash in lignocellulosic biomass are relatively lower than those of coal [1], the so-called slagging, fouling or agglomeration often causes challenges during direct energy use (i.e., combustion) and/or co-firing with coal in boilers and power plants [5][6][7].…”

“…Rice is the most abundant crop residue in Asia. It was estimated that the mass ratios of rice straw and rice husk to rice production were approximately 100% and 20%, respectively [10]. Due to its richness in lignocellulosic constituents and other nutrients, the biomass is currently reused as a variety of by-products or application fields [4,7,8,10,[18][19][20][21].…”

Rice is the most important cereal in Asia. However, it also results in the generation of large quantities of rice-derived residues (i.e., rice straw and rice husk). Due to the residues richness in lignocellulosic components, they potentially have considerable value in material and/or energy production without illegal burning in open fields. This work focused on investigating the thermochemical properties and inorganic/metal element contents of rice straw and rice husk. The former included proximate analysis, calorific value, thermogravimetric analysis (TGA) and energy dispersive X-ray spectroscopy (EDS). The latter covered the ten elements most relevant to their slagging/fouling indices. The results showed that they are suitable for energy use as biomass fuels, but rice husk was superior to rice straw because of the high silica content in the rice husk and the significant contents of potassium, sulfur and phosphorus in the rice straw. Using several slagging and fouling indices, the evaluation results were also consistent with their contents of inorganic elements or oxides. To increase the fuel properties of rice-derived residues, they could be pretreated with alkaline leaching, thus causing lower emissions of particulates and reduced slagging tendency when co-firing them with coal in industrial boilers.

“…In particular, RH contains cellulose and hemicellulose in various proportions (56%-75%), and 13.6%-34.8% of lignin [3,4]. All the rice in the world is grown over 140 million ha of land throughout Asia [5]. Generally, waste materials, such as RH, peanut shells, bamboo leaves, and sugarcane bagasse, are burned after harvest, and hence we lose a large number of nutrients contained in these waste materials.…”

Valorization of lignocellulosic rice husk producing biosilica and biofuels—a review

et al. 2022

View full text Add to dashboard Cite

Lignocellulosic biomass is an agricultural waste material abundantly produced in large quantities on earth. Rice husk (RH) is one of the lignocellulosic biomass and a huge byproduct of rice milling. Notably, the rice plant collects silica from the soil and stores the collected silica in the form of silicic acid inside the cellulose micro-compartments of the plant. Therefore, RH obtained from rice milling contains a significant quantity of amorphous silica, which can further be used for several other purposes. Furthermore, Silica-rich RH can be employed as raw material for the production of biofuels and biochars instantaneously via thermochemical processes like pyrolysis, gasification. This article thoroughly explored the prospective method of rice husk use to produce bio silica and energy at the same time, which is currently under investigation. Moreover, this study also discussed current improvements in the synthesis of RH silica materials and their long-term uses, particularly in energy and environmental functional materials. In terms of the environment, RH-silica materials may remove heavy metals and organic pollutants in soil amendment, wastewater treatment, and gas purification via adsorption, catalysis, and integrative methods. In essence, there are numerous research and development obstacles to the production of bio silica and biofuels, respectively, from RH to overcome, and this review article highlights all of them.
