The pyrolysis of six biomass samples consists of Rice husk (RH), Coconut shell (CS), and Walnut shell (WS) as lignocellulosic biomasses and Cladophora glomerata (CG), Gracilaria gracilis (GG), and Azolla filiculoides (AF) as algal biomasses were investigated at a constant operating condition in a fixed-bed reactor. The effect of biomass biochemical structure on the yields and composition of pyrolysis products and their potential for future applications were discussed. CS, AF, and CG showed respectively the highest yield of bio-oil (50.25 wt%), biogas (33.70 wt%), and biochar (40.21 wt%). WS, AF, and RHderived gas products had a medium level of LHV (10-13 MJ/Nm 3 ), and CG and GG algae samples had a very suitable H 2 /CO ratio close tow. Characterization of bio-oils showed that CS, WS had a high content of hydrocarbon components (23.5%, 17.6%, and 17%, respectively), and phenols (35.3% and 35.6%, respectively). Furthermore, useful nitrogen-containing components such as pyridine, nitrile, indole, and derivatives were detected in algae bio-oils. Biochar characterization showed the highest surface area and total pore volume for AF. Also, CG's biochar with a high concentration of carboxylic and carbonyl groups in their structure may be suitable for absorbing water and soil contaminants.

“…Acetogens are the most widely used anaerobic microbes through the Wood-Ljungdahl metabolic pathway which allows them to produce acetate and ethanol as the main end products, but also other acids and chemicals, such as acetic acid, butyric acid, hexanoic acid, isopropanol, butanol, hexanol, 2,3-butanediol, acetone, caproate, and lactate (Ljungdahl et al 1965;Ramachandriya et al 2016;Sun et al 2019;Ciliberti et al 2020). Furthermore, acetogens involved in syngas fermentation are able to operate under flexible CO:H2:CO2 ratios; thus, syngas reforming is not required to match fermentation conditions; however, traces of condensable volatiles (tar) present in the syngas may lead to intoxication of the acetogens and, therefore, must be removed (Ramachandriya et al 2016;Chowdhury et al 2019). We used Clostridium ljungdahlii in the model because it is the most studied acetogen for the conversion of syngas to ethanol (Köpke et al 2010).…”

The utilization of forest side-streams is associated with the applied bioenergy technology that must be impellent to support the increasing demand for biofuels and resources while lowering greenhouse gas (GHG) emission from the transport sector. This study aimed to estimate potential biofuel production from eutrophic (EL) and mesotrophic (ML) lake bottom biomass and the manufacturing side-streams from the pulp and paper mill (PI -PVIII). Theoretical biogas and bioethanol productions were modeled by Aspen Plus® simulation through 1) saccharification and fermentation, 2) gasification and mixed alcohol synthesis, 3) gasification-syngas fermentation, and (4) anaerobic digestion processes. In addition, the different process stages of the pulp and paper side-streams was studied by ABE fermentation using Clostridium acetobutylicum DSM 1731.The bioethanol produced from EL and ML biomass from indirect gasification and mixed alcohol synthesis were 244.5 L/t and 57.1 L/t, whereas the yields from saccharification and fermentation were 137 L/t and 40 L/t, respectively. The EL biomass produced the most profitable bioethanol production from the latter process. The ML and EL biomass produced biogas of 38.9 mL/g volatile solid and 136.6 mL/g volatile solid, respectively. The ash from the EL and ML biomass and the dried samples of PI and PIII could be used as fertilizer because the harmful elements for Finnish fertilizer products were below the detectable limit. The primary sludge (PII) sample had found high N and P concentrations and cadmium (Cd) concentration (3 mg/kg), which exceeded the Cd limit for Finnish fertilizer products (1.5 mg/kg). However, wet primary sludge (PII) forming 300,000 tonnes/year (72600 dry tonnes) produced anhydrous ethanol about 3011 kg/h (24,090 tonnes/year) when PII was used for the gasification-syngas fermentation process in the bioethanol plant model.Three pulp and paper side-streams (PI, PII and PIII) with unwashing and water washing were pretreated with dilute acid (0.2% H2SO4 at 180 °C for 10 min), followed by saccharification and ABE fermentation. The results suggested that water washing did not affect the PII and PIII prehydrolysate sugar recovery, as well as enzyme hydrolysis of the rejects from kraft pulping (PI) did not require prewashing before dilute acid pretreatment. In addition, the unwashed PI side-stream yielded the highest ABE concentration of 12.8 g/L, compared to the unwashed PII and PIII side-streams, 5.2 g/L, and 6.3 g/L, respectively. The side-streams from different process stages in pulp and paper mill were concluded to be high potential feedstocks for biofuels production due to their chemical compositions. The unwashed PI was suitable feedstock for butanol production, while PII could be fully utilized in the integrated gasification-syngas fermentation process. Primary sludge (PII) was found to be a promising feedstock for bioethanol and an internal rate of return (IRR) of 15 % can be obtained by two implementations. One was a cost-competitive ethanol selling price (ESP) of €0.6...

“…By merging the syngas platform with the carboxylate platform, i.e., combining syngas fermentation with fermentation of organic substrate, dry and moist or liquid biomass can be integrated in an optimal way. Thereby, MCC product yields and productivities are increased and product portfolios can even be expanded to bioalcohols (Baleeiro et al, 2019;Chowdhury et al, 2019).…”

Sugarcane is the most produced agricultural commodity in tropical and subtropical regions, where it is primarily used for the production of sugar and ethanol. The latter is mostly used to produce alcoholic beverages as well as low carbon biofuel. Despite well-established production chains, their respective residues and by-products present unexploited potentials for further product portfolio diversification. These fully or partially untapped product streams are a) sugarcane trash or straw that usually remain on the fields after mechanized harvest, b) ashes derived from bagasse combustion in cogeneration plants, c) filter cake from clarification of the sugarcane juice, d) vinasse which is the liquid residue after distillation of ethanol, and e) biogenic CO2 emitted during bagasse combustion and ethanol fermentation. The development of innovative cascading processes using these residual biomass fractions could significantly reduce final disposal costs, improve the energy output, reduce greenhouse gas emissions, and extend the product portfolio of sugarcane mills. This study reviews not only the state-of-the-art sugarcane biorefinery concepts, but also proposes innovative ways for further valorizing residual biomass. This study is therefore structured in four main areas, namely: i) Cascading use of organic residues for carboxylates, bioplastic, and bio-fertilizer production, ii) recovery of unexploited organic residues via anaerobic digestion to produce biogas, iii) valorization of biogenic CO2 sources, and iv) recovery of silicon from bagasse ashes.
