“…Higher ash content may reduce the heating value estimation of the biomass however it is beneficial from another perspective that higher ash content present in agricultural biomass waste has potential to be used in brick manufacture, catalyst production, silica recovery, etc. [30,31]. The lower volatile matter was found in the rice husk i.e.…”

Biomass-based energy from agricultural wastes is a promising alternative energy source since its abundant supply and renewable. Biomass is converted into gas and liquid fuel through biochemical or thermochemical treatments. In this work, oil palm empty fruit bunches (OPEFB) and rice husk are pyrolyzed to produce gas and liquid fuel. The reactor temperature and feed mass are varied to obtain the best operating condition in a semi-batch pyrolysis reactor. The experimental results showed that the best operating temperature in pyrolysis process to produce bio-oils from OPEFB and rice husk was at 500 °C with 4.3 % (w/w) and 2.6 % (w/w) of bio-oil yields, respectively. The pyrolysis product distribution and their chemical composition are strongly affected by operating condition and the types of biomass. The GC-MS analysis results showed that the primary pyrolysis products components consist of hydrocarbons and oxygenated compounds such as carboxylic acids, phenols, ketones and aldehydes. Thermodynamic properties such as thermal conductivity of the biomass also influenced the product distribution of the biomass pyrolysis.

Over the past century, the world's population has increased greatly. The growth in the population has increased the global food demand, so the food sector has increased its production. As a result of the increased production and consumption, a huge amount of agro-food waste is being generated yearly. Rice husk, wheat straw, sugarcane bagasse, corn husk, peanut shell, eggshell, are just a few examples of agro-food wastes. As these agro-food wastes and their by-products are left unused and unattended, their amount is increasing globally. It is imperative to find ways to put these wastes to environmentally viable use. These wastes find direct uses in biofertilizers, mud houses, animal feed, biofuel, and heat generation in small-scale industries, etc. After heat generation, ashes are considered as a secondary by-product, which can be used as a sustainable and renewable resource for synthesizing value-added products for various applications. This article presents a review of the traditional and advanced methods of utilizing these wastes in household applications, animal feed, fertilizers, fuel generation, pyrolysis, and for the removal of toxic metals from polluted water. These secondary resources can also be used in construction materials and for the synthesis of glasses and glass-ceramics, which can be used in bioengineering, optical, and dielectric materials. Agrofood wastes can be used as resource materials to develop modern materials with better properties instead of using minerals. This not only reduces the environment-and management-related problem of the wastes but also provides a sustainable alternative way to produce cost-effective value-added materials for the benefit of society.

“…On the other hand, the chemical analysis reveals that RHA contains 90%-99% of silica, which can be a cheap source to be used in several industrial sectors [2][3][4]. Several researchers have utilized silica obtained from RHA as a raw material for production in solar grade silicon (Si-GS) [5], silicon carbide (SiC) [6], silicon nitride ceramics (Si 3 N 4 ) [7] and mullite (a fibrous alumina silicate mineral of low thermal expansion, formed within porcelain bodies during firing and in industry by calcining) [8][9][10].…”

Rice husk is considered as a waste in the rice industry but is proficient in manufacturing different materials, such as zeolites, which is produced in large quantities all over the world, for example in Brazil. Zeolite is an adsorbent support material, which can be synthesized from rice husk ash (RHA) with external sources of aluminium (ESA). The scientific community has been conducting several measures to minimize the environmental impacts caused by greenhouse gases. Several mitigation processes are presently investigated, which includes carbon dioxide injections into adsorbent materials (e.g. zeolites). The efficiency of this technology involves a zeolitic material with high crystallinity and high concentrations of SiO 2 and Al 2 O 3 (aluminosilicates). In the present work, zeolites have been synthesized from rice husk ash (SiO 2 source) and external aluminium sources (Al 2 O 3 -alumina, gibbsite and metakaolin) to fulfill that purpose. With the aid of XRF, XRD, SEM/ EDS and FTIR techniques, the zeolitic material was characterized in two distinct crystalline phases: Mordenite and ZSM-5. The synthesis was carried out by the ideal addition of ESA (2.5 g) to RHA. According to the literature, the zeolitic materials formed by the mixture of Mordenite and ZSM-5 can be availed for gas separation and greenhouse gas storage.
