“…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).…”

“…In addition, so-called bioelectricity can be generated from sugarcane molasses by using microbial fuel cell technologies, which isolate specific bacterial strains (Hassan 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).…”

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.

“…The de-lignification is necessary to make the SCB more susceptible to enzyme attack. In some processes, lignin is first broken down and removed by special enzymes or chemicals (such as alkali), before further steps are taken to convert the remaining part of the SCB to bio-ethanol (Niju and Swathika 2019). (Maryana et al 2014) Lignin peroxidase, manganese peroxidase and laccase are the major enzymes for de-lignification and can be produced by white-rot fungi (Malik et al 2021).…”

Sugarcane (Saccharum officinarum) bagasse (SCB) is a biomass of agricultural waste obtained from sugarcane processing that has been found in abundance globally. Due to its abundance in nature, researchers have been harnessing this biomass for numerous applications such as in energy and environmental sustainability. However, before it could be optimally utilised, it has to be pre-treated using available methods. Different pre-treatment methods were reviewed for SCB, both alkaline and alkali–acid process reveal efficient and successful approaches for obtaining higher glucose production from hydrolysis. Procedures for hydrolysis were evaluated, and results indicate that pre-treated SCB was susceptible to acid and enzymatic hydrolysis as > 80% glucose yield was obtained in both cases. The SCB could achieve a bio-ethanol (a biofuel) yield of > 0.2 g/g at optimal conditions and xylitol (a bio-product) yield at > 0.4 g/g in most cases. Thermochemical processing of SCB also gave excellent biofuel yields. The plethora of products obtained in this regard have been catalogued and elucidated extensively. As found in this study, the SCB could be used in diverse applications such as adsorbent, ion exchange resin, briquettes, ceramics, concrete, cement and polymer composites. Consequently, the SCB is a biomass with great potential to meet global energy demand and encourage environmental sustainability.

“…The "food vs fuel" debate has reinvigorated an interest in the development of second generation biofuels owing to their socioeconomic benefits [279,280]. Lignocellulosic wastes are highly studied in DF processes because they are ubiquitous (have a global yield of more than 1.3 billion tons per annum) and are rich in nutrients [281][282][283][284].…”

The indiscriminate use of fossil fuels has led to several challenges such as greenhouse gas emissions, environmental degradation, and energy security. Establishment of clean fuels is at the forefront of science and innovation in today's society to curb these problems. Dark fermentation (DF) is widely regarded as the most promising clean energy technology of the 21st century due to its desirable properties such as high energy content, its non-polluting features, its ability to use a broad spectrum of feedstocks and inoculum sources, as well as its ability to use mild fermentation conditions. In developing nations, this technology could be instrumental in establishing effective waste disposal systems while boosting the production of clean fuels. However, DF is still hindered by the low yields which stagnate its commercialization. This paper reviews the recent and emerging technologies that are gaining prominence in DF based on information that has been gathered from recent scientific publications. Herein, novel enhancement methods such as cell immobilization, nanotechnology, mathematical optimization tools, and technologies for biogas upgrading using renewable H 2 are comprehensively discussed. Furthermore, a section which discusses the potential of bioenergy in Sub-Saharan Africa including South Africa is included. Finally, scientific areas that need further research and development in DF process are also presented.
