“…In this regard, the use of explosive steam decompression as a form of pretreatment has been proven to enhance the production of biogas. Moreover, ethanol production and syngas production using lignocellulosic feedstocks have also been reported to proceed with higher calorific value and lower temperatures, respectively, when precluded with steam explosion [28,29]. A promising solution for continuous steam explosion has been presented by a research team from South China University of Technology [30] allowing for process scale-up and its potential integration in second-generation biorefineries.…”

Processing of biomass feedstocks to produce energy, fuels, and chemicals via a combination of different applied technologies is considered a promising pathway to achieve sustainable waste management, with many environmental and economic benefits. In this chapter, we review the current state of the main processes associated with energy recovery and biofuel production under the concept of waste biorefineries. The reviewed technologies are classified into thermochemical, biological, and chemical, including combustion, gasification, steam explosion, pyrolysis, hydrothermal liquefaction, and torrefaction; anaerobic digestion, fermentation, enzymatic treatment, and microbial electrolysis; and hydrolysis, solvent extraction, transesterification, and supercritical conversion. Their brief history, current status, and future developments are discussed within a perspective of valorization and managing of current waste streams with no solution.

Biomass is a suitable alternative to be used as fuel, but the use of biomass without prior processing can cause respiratory disease. In Indragiri Hilir Regency, the utilization of palm fruit skin waste is still minimal. Bio-pellet is a fuel derived from biomass waste that has gone through a densification process. The process of making bio-pellets is carried out by refining the raw materials, mixing the adhesives, printing the raw materials that are pressed under high pressure, and drying. The results of the research on the bio-pellet characteristic test of Nipah fruit peel waste according to its parameters obtained an average value of 1.28% water content, 0.51% ash content, 21.3% flying substance content, 76.88% bound carbon content and weight. type 1.41 gr / cm3. For the combustion test in the updraft type gasification furnace with the addition of 0.5kg, 0.3kg and 0.2kg of fuel, the results obtained from the rate of fuel consumption are 0.041kg / minute, 0.033kg / minute and 0.033kg respectively. /minute. In the results of combustion efficiency, the value according to SNI 7926: 2013 is the addition of 0.5kg of fuel at the beginning of ignition and 0.2 kg at the end of ignition, which is 0.04.

“…Gunarathne et al [4] have studied on pretreatment of biomass, and this method is continuously increasing due to the high demand for it and retaining low energy density. They have used steam-blowed black pellets and unpretreated gray pellets to gasify with air and steam at an updraft high-temperature agent gasification unit.…”

Energy generation from carbon-based solid materials, such as coal by a gasification process, increasingly has become an essential research subject, as current energy sources are getting to an end. Waste material management is also of considerable significance to dispose of them sustainably and efficiently from the environment. There is, therefore, the need for an advanced modeling approach to maximize the efficiency of coal-derived synthesis gas, and to optimize process parameters for designing a new gasifier. Hence, a two-dimensional (2-D) gasification system was initially simulated by using commercial code ANSYS FLUENT. Devolatilization and char combustion chemical reactions of the process were modeled by User Defined Functions (UDF) to simulate their chemical kinetics more accurately. Once a mesh independency study was fulfilled, performance evaluation was done, and the energy efficiency of the gasification system was also calculated. Subsequently, model validation has been performed, and RANS based turbulence models were examined to find out the best turbulence modeling approach.
