“…In recent research, investigations into biomass pyrolysis involving sulfur-rich feedstocks have highlighted the notable generation of hydrogen sulfide (H 2 S) during the process [165]. Additionally, studies focused on waste materials, such as tires or rubberbased compounds, have demonstrated the liberation of sulfur compounds, notably H 2 S, when subjected to pyrolysis conditions [166]. These findings emphasize the diverse sources of sulfur emissions in pyrolysis and their consequential impact on air quality.…”

The production of biofuels and biochar through pyrolysis is a promising avenue for sustainable energy generation and waste management. However, this process can inadvertently release various air pollutants into the atmosphere, potentially compromising its environmental benefits. This article provides a comprehensive overview of the gas pollutants associated with pyrolysis for biofuel and biochar production, as well as different variables affecting gas emissions. Key pollutants such as particulate matter (PM), volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), carbon monoxide (CO), and nitrogen oxides (NOx) have been discussed in terms of their formations and emissions during pyrolysis processes. Furthermore, major factors influencing pollutant emissions, including feedstock composition, pyrolysis conditions, and combustion technologies have been examined with up-to-date examples. The review highlights the significance of emission control strategies, such as advanced reactor design, catalyst utilization, and the integration of realtime monitoring systems, in mitigating air pollution from pyrolysis processes. By shedding light on the environmental challenges associated with pyrolysis-based biofuel and biochar production, this article aims to encourage the development of cleaner and more sustainable approaches to harness the potential of solid waste conversion technologies.

The quality of air is vital for our existence. Increasing industrial development and household activities will increase the risk of air pollution and environmental damage. Some air pollution in ambient air quality is very toxic and lethal. One method that can remove gaseous pollutants is adsorption. Previous study about banana plant as adsorbent of gaseous pollutant, banana leaves has the highest adsorption efficiency value of 76.52%. Purpose of this study to discuss characteristics and potential of banana leaves as gaseous adsorbent. This research was carried out by studying literature and testing the Scanning Electron Microscope (SEM) of the banana leaf surface morphology. The structural properties of adsorbent were characterized, which exhibited the adsorbent’s porous surface or stomata. There are several studies of the SEM analysis results that explain stomata are able to trap air pollution. Banana leaves contain lignin, cellulose, and cuticle which have been found in several studies to be useful as gas adsorbents. Based on these studies, it can be concluded that banana leaves have potential as an adsorbent of gaseous pollutants.

“…The flaming combustion of rubber particles can also generate large volumes of carbon soot and toxic fumes such as hydrogen sulphide (H 2 S). 26 Therefore, it is important that engineers not only derive a good understanding of the impact of rubber fillers on mechanical properties, but thermal and flammability characteristics of syntactic foam prior to integration onto fire-prone structures. By studying the thermal properties and flammability of the rubber-reinforced syntactic foam, foam manufacturers can identify optimal rubber filler concentrations while maintaining the fire resistance of the rubberised foam products.…”

The management of end‐of‐life tyres faces challenges due to insufficient recycling infrastructure and technologies, as well as limited markets for the materials recovered from them. To mitigate this, waste rubber can be upcycled and used as filler material for polymer matrix composites. Before rubber‐reinforced composites can be certified for fire‐prone applications, their thermal and flammability properties must be understood. This research investigates the effect of rubber fillers on the thermal stability, flammability and flame spread characteristics of epoxy matrix syntactic foam. Thermogravimetric analysis, Fourier Transform Infrared spectrometry (FTIR), scanning electron microscopy and attenuated total reflection FTIR spectrometry were employed to elucidate changes in thermal degradation behaviours. The influence of rubber fillers on the flammability of syntactic foam was assessed using the cone calorimeter. The fire reaction properties of rubber‐reinforced foam were affected by the intensity of the incident heat flux. Regardless of the incident heat flux, an increase in rubber content led to higher total heat release. At the lower heat flux of 35 kW/m2, the fire growth rate increased with rubber content, but at the higher heat flux of 50 kW/m2, the fire growth rate decreased as the rubber content increased. Importantly, all rubber‐reinforced syntactic foams achieved a UL94 HB ranking and exhibited reduced flame spread rates compared to the unmodified foam. This study demonstrated the potential for upcycling waste rubber into sustainable engineering products and expanded the knowledge base on fire reaction properties and flame spread characteristics of such hybrid composite materials.
