“…Therefore, it is of great importance to explore the possibility of introducing a metal honeycomb catalyst in biomass combustion systems to reduce future environmental impacts and climate change effects. Pyrolysis of rice husk (separating the bio-oil from the ash) combustion has been performed to minimize particulate matter (PM) emissions [4]. However, the particulate matter and gaseous emissions such as carbon monoxide (CO), nitrogenous oxide (NOx), and sulfur dioxide (SOx), from these systems are significant and there is less infrastructural investment compared to direct combustion.…”

“…However, the particulate matter and gaseous emissions such as carbon monoxide (CO), nitrogenous oxide (NOx), and sulfur dioxide (SOx), from these systems are significant and there is less infrastructural investment compared to direct combustion. In addition, rice husk ash has been used in cement-based materials for environmental benefits and performance improvement [4][5][6]. This is an additional advantage of direct combustion.…”

“…Biomass incineration is the easiest technique for producing biomass energy, either through direct combustion or as co-combustion with other fuels such as poultry litter and natural gas co-combustion to generate electricity using a sterling engine [7] and hot water using shells and a tube heat exchanger [4]. However, it has been plagued with the release of toxic pollutants, such as PM, CO, NOx, and SOx.…”

Most studies on honeycomb catalysts have been conducted using simulation models and exhaust experiments from automobiles. Very few monolithic catalyst studies have been applied to the agricultural sector, especially the catalyst exhaust system for flue purification from the biomass industry. The importance of exhaust gas purification and particulate removal from biomass power plants has become critical for evaluating the performance and environmental sustainability of biomass combustion. This is one of the first studies to investigate the performance of honeycomb catalysts for the oxidation of flue (PM2.5), (CO), and (SO2) from a rice husk briquette combustion system. The experimental setup comprised a fixed-bed electric furnace, the catalyst, an aerosol sampler, and a flue gas analyzer. Rice husk (0.1 g/mL density) and rice husk briquettes (0.8 g/mL density), were burned at 600–1000 °C for 3 min. From the results, the catalyst CO conversion rate was 100% at the optimum heated temperatures of 427.4–490.3 °C. At these temperatures, the inhibition effect of the chemisorbed CO was significantly minimized, enhancing the adsorption of oxygen, which reacted with CO to form CO2. However, SO2 oxidation was lower than that of CO because platinum-based catalysts are generally more attracted to CO in the presence of oxygen. The emission of PM2.5 decreased from its uncatalyzed-value (1169.9 mg/m3 and 1572.2 mg/m3) to its catalyzed values (18.9 mg/m3 and 170.1 mg/m3). This is a significant result in ensuring cleaner production of energy from rice husk.

“…This might take place via (I) increasing soil water retention 24,25 , hence reducing soil irrigation demands 26,27 , (II) increasing nutrient use e ciency 28 , (III) stimulating auxin, gibberellin and brassinosteroids regulation 29 and (IV) increasing plant chlorophyll content, stomatal conductance, cytotoxicity and leaf K + content 30 . This cost-effective carbon rich product is formed through the pyrolysis of organic residues under limited oxygen supply 31 to give a product of high porous aromatic carbon content 32 . It is worth mentioning that this product retains longer in soil versus other organic residues such as compost; hence mitigate climate changes through carbon sequestration 33 .…”

Drought stress is among the major constraints that threat agricultural productivity within the arid and semi-arid regions, worldwide. In this study, wheat (a strategic crop) was selected to test its growth under drought stress and the mechanisms beyond this adaptation while considering two factors, i.e., (1) deficit irrigation at 35% of the water holding capacity (WHC) versus 75% of WHC (Factor A) and (2) the following safe treatments: the control treatment (C), amending soil with biochar (BC) at a rate of 2%, foliar application of 24-epibrassinolide at two different levels (1 (BR1) or 3 (BR2) μmol) and the combination between BC and BR treatments. The obtained results were statistically analyzed, and the heat-map conceits between measured variables were also calculated by using the Python software. This investigation took place under the greenhouse conditions for 35 days following a complete randomized design and all treatments were replicated trice. Results obtained herein revealed that drought stress decreased all studied vegetative growth parameters (root and shoot biomasses) and photosynthetic pigments (chlorophyll a, b and total contents while increased oxidative stress indicators. All additives, specifically the combined ones BR1+BC and BR2+BC, were effective in increasing growth attributes, photosynthetic pigments and ion assimilation by wheat plants. They also upraised the levels of enzymatic and non-enzymatic antioxidants while decreased stress indicators. Furthermore, they increased Ca, P and K content within plants. It can therefore be deduced that the integral application of BR and BC is essential to mitigate drought stress in plants.
