“…The reasons for this are many: the dwindling supplies of fossil fuels and their increasing prices; efforts to reduce environmental pollution caused by fossil fuels; and increasing of renewable energy using or spreading the knowledge about proper waste management. Nowadays, both scientific research and the commercial sector, focus on utilization of green and clean renewable energy sources in order to generate different kinds of biofuel (solid, liquid, and gaseous) by valorization of various waste biomass (WB) (Adarme et al, 2019; Hawkes et al, 2002; Logan and Regan, 2006; Niju and Swathika, 2019; Soto et al, 2019; Vats et al, 2019; Yusuf, 2017). Currently, WB (originating prevalently from the agricultural sector) is considered as the largest source of renewable energy in the world (Niu et al, 2019).…”

“…Sugarcane bagasse suitability for liquid biofuel production was also proved, namely in bioethanol and biodiesel production by fermentation due to its high content of cellulosic fibres (Niju and Swathika 2019; Soto et al, 2019). In the case of gaseous biofuel, sugarcane bagasse proved its potential for biogas generation by anaerobic digestion, which takes place in biogas plant stations (Adarme et al, 2019; Vats et al, 2019). Therefore, the spectrum of sugarcane bagasse sustainable reuse is very wide.…”

The present research describes an application of high-pressure briquetting technology to the waste management of sugarcane processing in Vietnam. The amount of generated sugarcane bagasse was monitored during sugarcane processing within the street juice production in Hue city, Vietnam. Generated sugarcane bagasse was subjected to fuel parameters analysis within its suitability for direct combustion. The obtained sugarcane bagasse was converted into bio-briquette fuel by a high-pressure briquetting press and its mechanical quality was determined. Results proved that the proportion of generated sugarcane bagasse from whole sugarcane stem mass was equal to 35.45%. This indicated generation of an abundant amount of sugarcane bagasse worldwide in general. Fuel parameters analysis proved high quality level of low ash content = 0.97% and high calorific values (gross calorific value = 18.35 MJ·kg-1, net calorific value = 17.06 MJ·kg-1), which indicated good suitability for direct combustion processes. Indicators of mechanical quality proved the following observations: mechanical durability = 99.29%, compressive strength = 150.82 N∙mm-1 and bulk density = 1022.44 kg·m-3, with all these indicators representing positive results. In general, the observed results indicated suitability of sugarcane bagasse valorization within the production of bio-briquette fuel by using high-pressure briquetting technology. Finally, analysis of such waste biomass proved its great potential for energy recovery, thus, the advantage of its valorization within the sustainable technologies.

“…Despite the low biomass yield per area, rice cultivation occupied the largest area of agricultural land in the country. This was supported by the fact that rice paddies accounted for more than 50% of total agricultural land [119]. The third largest crop for biomass generation is palm, which is a vital crop for biodiesel in Thailand.…”

“…Meanwhile, bagasse and molasses are the major by-products of the sugar milling process and account for around 30% of the biomass from dry biomass [47,53,54]. In addition to bagasse, waste from the sugar milling industry, including vinasse and bagasse fly ash, have been studied in the anaerobic co-digestion process in biomethane production by installing biogas in the system [119]. Currently, this crop has contributed to a broad range of valuable products in addition to the production of sugar.…”

The agricultural sector is a major source of biomass feedstocks for biofuels. Even though biomass potential in Thailand has been analyzed on a national level, its distribution and potential have yet to be assessed on a regional and provincial scale. Therefore, the study aims to verify the possibility of decentralized second-generation bioethanol production from regionally available agricultural residues. Most of the generated residues stem from the country’s major crops (sugarcane, cassava, rice and palm), totaling 174.1 million tons per year. The volume of bioethanol from these residues is projected to be 20,213.5 million liters per year, meeting 31.2% of the overall fuel demand of the transport sector. At the regional level, the northeast produces the highest amount of bioethanol at 9099.7 million liters per year, followed by the central, northern and southern regions. In terms of provincial distribution, the highest amount of bioethanol is converted in Nakhon Ratchasima, amounting to 1328 million liters per year. Data from the top ten potential provinces suggest that decentralizing production facilities is possible. One of the hotspots is Surat Thani in the south which can potentially utilize palm residues as feedstocks. This regionalized assessment also found that conventional feedstocks could be substituted with regionally available residues in the 26 production plants currently in operation. The results confirm that there would be enough alternative regional feedstocks to meet existing production capacities and they indicate that there would be enough regional residues left over for future value-added utilization.

This work evaluated the methane (CH4) production potential from residues of integrated 1st (vinasse and filter cake) and 2nd (deacetylation pretreatment liquor from straw) generation (1G2G) sugarcane biorefinery. The small-scale study provided fundamentals for basing the optimization of co-digestion by assessing the best co-substrates synergistic conditions. Biochemical Methane Potential (BMP) tests showed co-digestion enhanced CH4 yield of isolated substrates, reaching 618 NmLCH4 gVS-1, and all of the experiments were well describe by modified Gompertz model. Vinasse and deacetylation liquor as the only co-substrates increased the BMP by 36.75%, indicating that the association of these two residues provided positive effects for co-digestion by nutritionaly benefeting the methanogenic activity. The filter cake had the lowest BMP (260 NmLCH4 gVS-1) and digestibility (<40%), being the stirring required to improve the mass transfer of biochemical reactions. The alkaline characteristic of the liquor (pH-12) prevented alkalinizers from being added to the co-digestion, which could be a relevant economic advantage for the implementation of the process in an industrial scale. The co-digestion system has proven to efficiently maximize waste management in the 1G2G sugarcane biorefineries and potentially enhance their energy generation (by at least in 18%), providing experimental elements for placing the biogas production as the hub of the bioeconomy in the agroindustrial sector.
