The recent implication of circular economy in Australia spurred the demand for waste material utilization for value-added product generations on a commercial scale. Therefore, this experimental study emphasized on agricultural waste biomass, rice husk (RH) as potential feedstock to produce valuable products. Rice husk biochar (RB) was obtained at temperature: 180 °C, pressure: 70 bar, reaction time: 20 min with water via hydrothermal carbonization (HTC), and the obtained biochar yield was 57.9%. Enhancement of zeta potential value from − 30.1 to − 10.6 mV in RB presented the higher suspension stability, and improvement of surface area and porosity in RB demonstrated the wastewater adsorption capacity. Along with that, an increase of crystallinity in RB, 60.5%, also indicates the enhancement of the catalytic performance of the material significantly more favorable to improve the adsorption efficiency of transitional compounds. In contrast, an increase of the atomic O/C ratio in RB, 0.51 delineated high breakdown of the cellulosic component, which is favorable for biofuel purpose. 13.98% SiO2 reduction in RB confirmed ash content minimization and better quality of fuel properties. Therefore, the rice husk biochar through HTC can be considered a suitable material for further application to treat wastewater and generate bioenergy.

“…This may have a major impact on both environmental and energy-saving aspects [2,15,16,28]. A study demonstrated that a solid-state fuel cell with electric motor and controller can produce electricity from bioethanol with 75-80% conversion efficiency [29][30][31]. However, very little research and design have been conducted on bioethanol-electricity generation.…”

Banana stem is being considered as the second largest waste biomass in Malaysia. Therefore, the environmental challenge of managing this huge amount of biomass as well as converting the feedstock into value-added products has spurred the demand for diversified applications to be implemented as a realistic approach. In this study, banana stem waste was experimented for bioethanol generation via hydrolysis and fermentation methods with the presence of Saccharomyces cerevisiae (yeast) subsequently. Along with the experimental analysis, a realistic pilot scale application of electricity generation from the bioethanol has been designed by HOMER software to demonstrate techno-economic and environmental impact. During sulfuric acid and enzymatic hydrolysis, the highest glucose yield was 5.614 and 40.61 g/L, respectively. During fermentation, the maximum and minimum glucose yield was 62.23 g/L at 12 h and 0.69 g/L at 72 h, respectively. Subsequently, 99.8% pure bioethanol was recovered by a distillation process. Plant modeling simulated operating costs 65,980 US$/y, net production cost 869347 US$ and electricity cost 0.392 US$/kWh. The CO 2 emission from bioethanol was 97,161 kg/y and SO 2 emission was 513 kg/y which is much lower than diesel emission. The overall bioethanol production from banana stem and application of electricity generation presented the approach economically favorable and environmentally benign.

“…The elemental analyzer must be able to perform the analysis for carbon, hydrogen, nitrogen and sulfur simultaneously for 4-5minutes. Bomb calorimeter AC-500 used to calculate the calorific value of walnut shell and blend of walnut shell with coal [19,20]. A Windows-based operating system uses an electronic thermometer with an accuracy of 0.0001°C to measure the temperature every six seconds.…”

Попередня обробка пакистанського вугілля є серйозною проблемою. Тому в цьому дослідженні використовується суміш вугілля та шкаралупи волоського горіха для збагачення великої кількості вугілля за допомогою шкаралупи волоського горіха. У цьому дослідженні використовували співвідношення обох видів сировини 50 : 50, яка піролізувалися в реакторі з нерухомим шаром. Термічне розкладання суміші шкаралупи волоського горіха і вугілля було досліджено за допомогою ТГ-ДТА аналізу при різних швидкостях нагрівання 10, 20 і 25 °C/хв. За 427 °C і 25 °C/хв спостерігалося максимальне розкладання суміші, що вказує на те, що 26.4 % біомасла та 39 % фракції біовугілля можуть бути використані як паливо. Мінімальна кількість краща для активації енергії при низькій конверсії, а найбільша кількість енергії активації 190 кДж/моль отримується при конверсії 0.6. Біовугілля, отримане після піролізу суміші шкаралупи волоського горіха та деревного вугілля, також було охарактеризовано за допомогою технічного аналізу, а елементний аналіз показав, що частка сірки знизилася з 4.48 % до 0.85 %, а теплотворна здатність збільшилася до 22.4 МДж/кг.
