“…Aiming to improve the mechanical and physico-chemical properties of the solid fuel, many organic and inorganic binders may be used for the densification process [22] [23] such as starch, protein, fiber, fat/oil, and other additives. The addition of binders in the densified solid fuel production using lignocellulosic biomass as raw materials might have a positive outcome on the strength, in a similar way to the resins used in the production of wood boards [24] [25].…”

Aiming to use lignocellulosic biomass as energy source, one of the process that may aggregate values is the densification process, which allows the production of bioenergy using solid fuels, mainly for reducing transportation costs. In this research, solid fuel from co-briquetting of wood residues from sawmill using commercial kraft lignin as binder was investigated. The effects of compression pressure (900, 1200 and 1500 PSI) and briquette formulation (varying wood and kraft lignin proportion) on the quality and characteristics of briquettes were evaluated. The main findings were that briquetting of wood residues with kraft lignin resulted in an improvement of bulk density, strength rupture modulus, low heating value (LHV) and high heating value (HHV). The briquettes using 4% and 6% of kraft lignin, and submitted to 1200 to 1500 PSI, presented higher bulk density and strength resistance, respectively. On the other hand, the heating values showed the highest results with the addition of 2% lignin at 900 PSI, being the legal range for additives in briquettes for many countries such as in European Union.

“…As one of three kinds of pyrolytic products, the char is is composed mainly of carbon, inorganics and volatile hydrocarbons [20] . Pyrolytic char can be utilized directly as solid fuel, [21] soil amendment [22] and low cost adsorbent [23] . Besides, it also has a great potential as a feedstock for the production of activated carbon [24,25] .…”

Pyrolysis of paper and polyethylene in Tetra Pak waste occurred at 368 and 490 °C, respectively, while aluminum did not melted until the temperature reached 660 °C, thus aluminum and char can be obtained by carbonization of Tetra Pak waste at 550 °C. Pyrolytic char was processed into porous carbons by different methods. Specific surface area of the porous carbon prepared by carbonization of acid‐washed char at 850 °C achieved 741 m2 g−1, and the specific surface area of the porous carbon prepared from char by successively carbonization at 850 °C and acid‐washing was 732 m2 g−1. The developed porous structure was formed due to the polymerization of char above 650 °C, while the etching of char by CO2 generated via decomposition of inherent calcite led to a lower microporosity. Methylene blue adsorption capacity of the optimized sample reached 140 mg g−1, and the equilibrium data followed Langmuir model.

“…It has additional advantages of being carbon neutral, 12‐14 storage, direct replacement of diesel generator, etc. There are many forms of biomass used for electricity purposes, but the forest and agricultural residues are commonly used because of their high calorific value, locally available, and low cost 15‐17 . The forest biomass accounted for more than 80% supply of biomass for bioenergy systems globally, while 10% comes from the agriculture sector 18 .…”

Summary Growth in global energy demand, with major fossil fuel consumption, has induced detrimental environmental and social impacts. Therefore, in recent years, technologies focused on renewable energy utilization, including biomass energy, have evolved to meet the energy requirements. Bioenergy‐based power generation systems are among the best‐unutilized configurations to diminish reliance on fossil fuels. However, it is difficult to select a biomass‐based configuration for economical, sustainable, and reliable power generation. Understanding different possible configurations of biomass‐based energy systems, design parameters, system research gaps, and integration challenges in biomass‐based energy systems are important for further development and propagation. This paper presents a critical review of biomass‐based different hybrid configurations with solar, wind, fuel cell, micro‐hydro, geothermal, and diesel generator, and various designing parameters, challenges, and gaps with future scope. To restrict the scope of the review, only the gasification and anaerobic digestion related biomass electricity generation systems are considered. The analysis indicates that the biomass‐based hybrid energy systems can provide an eco‐friendly and cost‐effective solution, especially for off‐grid rural electrification. The solar radiation, load demand, fuel price, capacity shortage, interest rate, wind speed, biomass quantity, and electricity rate are among the most critical designing parameters in biomass‐based energy systems. The study provides valuable information to designers, researchers, and policy makers on the latest design constraints and relevant policies relating to biomass‐based hybrid energy systems.
