“…For instance, hydrocarbon and heavy metals that could be generated have environmental effects. Pudasainee et al [8] has reported the occurrence of trace metals in straw char and glycol used in gasification. Other by-product include char, tar, ash spent catalysts, and other air emission and noise [38].…”

“…Renewable energy from biomass is environmentally friendly when compared to fossil fuel resources; hence they are agent of sustainable development. Biomass fuels have environmental and social benefits [8]. Panwar et al [9] considered biomass as carbon neutral, due to the fact that the amount of carbon released is equivalent to the amount absorbed during its life time.…”

“…Zhang et al [16] reported that gasification is similar to combustion but it is frequently considered as partial combustion process. Pudasainee et al [8] also described gasification technology as one of the promising technologies for syngas production. The fundamentals of gasification, biomass constituents, type of gasifers, operating conditions and cleaning system have been comprehensively documented by Ruiz et al [14].…”

This study estimated bioelectricity potentials of under-utilized oil palm processing solid wastes (chaff, empty fruit bunch, palm press fibre and palm kernel shell) in Nigeria. The potential challenges of bio-power production from these solid wastes were also evaluated. Quantitative approach was employed for data generation. Historical data study of oil palm growth rate between 2004 to 2013 was used and projections at three scenarios (high, low and current status) were made. The findings showed that bioelectricity from total possible gatherable under-utilized oil palm processing solid wastes in Nigeria were 3.234 to 5.175 MWh in 2004, which could have reached 3.796 to 6.073 MWh in 2013. Based on projections at high, low and current growth rate scenarios, 5.728 to 9.165 MWh (high growth rate), 4.720 to 7.536 MWh (low growth rate) and 4.242 to 6.787 MWh (current growth rate) of electricity at efficiency of 80% (for combustion), 65% (for pyrolysis) and 50% (for gasification) could be achieved by 2029. After considering all the challenges associated with each type of conversion process, only 40% of these values are attainable. The study identified technological, policy/political and economic framework as potential challenge of bioelectricity generation in Nigeria. Hence the study concludes by suggesting means of overcoming the hurdles under Nigeria setting.

“…Many previous studies have shown that As, Pb, Cd, and Zn are found in gaseous emissions at low temperatures during thermochemical processes (Nzihou and Stanmore, 2013;Pudasainee et al, 2014). In particular, studies have shown that As is mostly present in the gas phase as arsenic oxide (As2O3) at low temperature during the thermochemical treatment of As-contaminated biomass (<500°C) (Nzihou and Stanmore, 2013;Contreras et al, 2009).…”

Large quantities of contaminated biomass due to phytoremediation were disposed through combustion in low-income rural regions of China. This process provided a solution to reduce waste volume and disposal cost. Pilot-scale combustion trials were conducted for in site disposal at phytoremediation sites. The reaction mechanism of arsenic capture during pilot-scale combustion should be determined to control the arsenic emission in flue gas. This study investigated three Pteris vittata L. biomass with a disposal capacity of 600 kg/d and different arsenic concentrations from three sites in China. The arsenic concentration in flue gas was greater than that of the national standard in the trial with no emission control, and the arsenic concentration in biomass was 486 mg/kg. CaO addition notably reduced arsenic

“…PM 2.5 emission from gasification and melting of MSW accounted for 2.5% of total PM 2.5 emissions from all sorts of thermal treatment of MSW in Japan. Trace metals emission and size distribution of PM generated from biomass gasification were reported in several studies (Min et al, 2016;Nzihou and Stanmore, 2013;Pudasainee et al, 2014). The emission of potassium-and sodium-containing compounds during rapid birchwood pyrolysis was also studied (Davidsson et al, 2002).…”

Gasification and pyrolysis technologies have been widely employed to produce fuels and chemicals from solid wastes. Rare studies have been conducted to compare the particulate emissions from gasification and pyrolysis, and relevant inhalation exposure assessment is still lacking. In this work, we characterized the particles emitted from the gasification and pyrolysis experiments under different temperatures (500, 600, and 700 °C). The collection efficiencies of existing cyclones were compared based on particle respiratory deposition. Sensitivity analysis was conducted to identify the most effective design parameters. The particles emitted from both gasification and pyrolysis process are mainly in the size range 0.25-1.0 μm and 1.0-2.5 μm. Particle respiratory deposition modelling showed that most particles penetrate deeply into the last stage of the respiratory system. At the nasal breathing mode, particles with sizes ranging from 0.25 to 1.0 μm account for around 91%, 74%, 76%, 90%, 84%, and 79% of the total number of particles that deposit onto the last stage in the cases of 500 °C gasification, 600 °C gasification, 700 °C gasification, 500 °C pyrolysis, 600 °C pyrolysis, and 700 °C pyrolysis, respectively. At the oral breathing mode, particles with sizes ranging from 0.25 to 1.0 μm account for around 92%, 77%, 79%, 91%, 86%, and 81% of the total number of particles that deposit onto the last stage in the six cases, respectively. Sensitivity analysis showed that the particle removal efficiency was found to be most sensitive to the cyclone vortex finder diameter (D). This work could potentially serve as the basis for proposing health protective measures against the particulate pollution from gasification and pyrolysis technologies.
