“…Biobutanol produced from the biological route of acetone-butanol-ethanol (ABE) fermentation by Clostridia species has the same chemical properties with butanol produced from petrochemical route. This biobutanol offers an alternative solution for energy security and mitigates greenhouse gases emission as it can be derived from sustainable and renewable substrates [ 4 , 5 ]. Biobutanol has a good blending ability with gasoline at any ratio or as a drop in an existing vehicle engine.…”

“…Biobutanol from renewable substrates including non-food lignocellulosic biomass are more suitable as fermentation feedstock as it does not compete with food crops demand [ 5 ]. In Malaysia, oil palm empty fruit bunch (OPEFB) fibres are the most abundant biomass produced at the palm oil mill with an annual production of 69,000 dry tonnes [ 7 ].…”

Optimisation of Simultaneous Saccharification and Fermentation (SSF) for Biobutanol Production Using Pretreated Oil Palm Empty Fruit Bunch

et al. 2018

This study was conducted in order to optimise simultaneous saccharification and fermentation (SSF) for biobutanol production from a pretreated oil palm empty fruit bunch (OPEFB) by Clostridium acetobutylicum ATCC 824. Temperature, initial pH, cellulase loading and substrate concentration were screened using one factor at a time (OFAT) and further statistically optimised by central composite design (CCD) using the response surface methodology (RSM) approach. Approximately 2.47 g/L of biobutanol concentration and 0.10 g/g of biobutanol yield were obtained after being screened through OFAT with 29.55% increment (1.42 fold). The optimised conditions for SSF after CCD were: temperature of 35 °C, initial pH of 5.5, cellulase loading of 15 FPU/g-substrate and substrate concentration of 5% (w/v). This optimisation study resulted in 55.95% increment (2.14 fold) of biobutanol concentration equivalent to 3.97 g/L and biobutanol yield of 0.16 g/g. The model and optimisation design obtained from this study are important for further improvement of biobutanol production, especially in consolidated bioprocessing technology.

“…Literature reports on the yield values of the ABE process starting from these precursors, estimated at around 4.54 kg of corn per liter of ButOH (corn worldwide production of 1.2 billion Mt in 2021) 22 and on 25 kg of sugarcane per L ButOH (sugarcane worldwide production of 181 Mt in 2021). 23,24 Alternatively, it can be obtained from propylene (hydroformylation to butyraldehyde and hydrogenation to 1-butanol), ethanol (dehydrogenation to acetaldehyde, aldol condensation, dehydration and hydrogenation of crotonaldehyde) or the catalytic hydrogenation of CO. 21 Bio-ButOH world production ranges from 3.0 Mt to 3.6 Mt. 25,26 In 2022 the US production was estimated to be around to 1.7 Mt, with a global market volume of 17.8 billion USD.…”

Maleic anhydride from bio-based 1-butanol and furfural: a life cycle assessment at the pilot scale

show abstract

“…Quite a number of recent studies have been undertaken, adopting the use of life-cycle assessment (LCA) for quantifying carbon emissions of agro-industry products. Some current and related studies have assessed the CF of sugarcane biofuel production [36][37][38][39][40][41], bioelectricity production from sugar cane bagasse in the sugar and ethanol sectors [42], and sugar produced from cultivated sugarcane [43][44][45]. Meanwhile, for irrigated and non-irrigated sugarcane [46][47][48], irrigation contributes to a higher energy input due to pumping of water especially from downstream to upstream and other field operations compared to rainfed sugarcanes.…”

Greenhouse gas (GHG) emissions from reservoirs are responsible for at most 2% of the overall warming effects of human activities. This study aimed at incorporating the GHG emissions of a reservoir (with irrigation/sugar production as its primary purpose), into the carbon footprint of sugar produced from irrigated sugarcane. This study adopts a life-cycle assessment (LCA) approach and encompasses the cradle-to-gate aspect of the international organization of standardization ISO 14040 guidelines. Results show that total carbon footprint of refined sugar could be as high as 5.71 kg CO2-eq/kg sugar, over its entire life cycle, depending on the priority of purposes allocated to a reservoir and sugarcane productivity. Findings also reveal that the dammed river contributes the most to GHG emissions 5.04 kg CO2-eq/kg sugar, followed by the agricultural stage 0.430 kg CO2-eq/kg sugar, the sugar factory 0.227 kg CO2-eq/kg sugar, and lastly the transportation stage 0.065 kg CO2-eq/kg sugar. The sensitivity analysis shows that carbon footprint CF of sugar production is largely influenced by the rate of biomass decomposition in the impounded reservoir over time, followed by the reservoir drawdown due to seasonal climatic fluctuations. Significant amounts of GHG emissions are correlated with the impoundment of reservoirs for water resource development projects, which may account for up to 80% of total GHG emissions to the reservoir’s primary purpose. Sugar production expansion, coupled with allocating more functions to a reservoir, significantly influences the CF of sugar per service purpose. This study is an indicator for policymakers to comprehend and make plans for the growing tradeoffs amongst key functions of reservoirs.
