Biomass pyrolysis is one of the beneficial sources of the production of sustainable bio-oil. Currently, marketable bio-oil plants are scarce because of the complex operations and lower profits. Therefore, it is necessary to comprehend the relationship between technological parameters and economic practicality. This review outlines the technical and economical routine to produce bio-oils from various biomass by fast pyrolysis. Explicit pointers were compared, such as production cost, capacity, and biomass type for bio-oil production. The bio-oil production cost is crucial for evaluating the market compatibility with other biofuels available. Different pretreatments, upgrades and recycling processes influenced production costs. Using an energy integration strategy, it is possible to produce bio-oil from biomass pyrolysis. The findings of this study might lead to bio-oil industry-related research aimed at commercializing the product.

Abstract Bio-derived activated porous carbon is readily used because it exhibits high surface area, excellent electrical conductivity, high stability, environment-friendly nature, and easy availability. All of these properties make it a unique and a perfect applicant for energy storage devices. Biowastes such as corncobs, walnut shells, human hair, jute, oil seeds, and bamboo are utilized as precursors in manufacturing porous carbon. The use of bio materials is preferred because of their abundance and biodegradable nature. The production of porous carbon was carried out through pyrolysis with the help of acid, primarily KOH, as the active substance. The ambient temperature for conducting pyrolysis is 400-800oC. Pyrolysis can be either fast or slow, with fast pyrolysis being helpful in most experiments. Food wastes like peels and shells are among the most significant biowaste sources alongside farm waste like rice husks, coconut shells, etc., which are not just waste and can be utilized for sustainable living. The porous carbon is formed from food waste from toxicity reducer in wastewater to for a supercapacitor or a bio anode in a microbial fuel cell. It is oneway sustainable development and is now highly economical. Moreover, in scientific aspects, their validity in a field and lowered expenses in some cases, the benefits of their usage may vary. This paper aims to extensively review all of the research conducted for Bio-waste utilization and its conversion to porous carbon for further use in super capacitance applications

Biomass fast pyrolysis oil is a potential renewable alternative to fossil fuels, but its viability is constrained by its corrosiveness, low higher heating value and instability, caused by high oxygenate concentrations. A few studies have outlined layered double hydroxides (LDHs) as possible catalysts for the improvement of biomass pyrolysis oil characteristics. In this study, the goal was to reduce the concentration of oxygen-rich compounds in E. grandis fast pyrolysis oils using CaAl- and MgAl- LDHs. The LDHs were supported by mesoporous silica, synthesised at different pHs to obtain different pore sizes (3.3 to 4.8 nm) and surface areas (up to 600 m2/g). The effects of the support pore sizes and use of LDHs were investigated. GC/MS results revealed that MgAl-LDH significantly reduced the concentrations of ketones and oxygenated aromatics in the electrostatic precipitator oils and increased the concentration of aliphatics. CaAl-LDH had the opposite effect. There was little effect on the oxygenate concentrations of the heat exchanger oils, suggesting that there was a greater extent of conversion of the lighter oil compounds. Bomb calorimetry also showed a marked increase in higher heating values (16.2 to 22.5 MJ/kg) in the electrostatic precipitator oils when using MgAl-LDH. It was also found that the mesoporous silica support synthesised at a pH of 7 was the most effective, likely due to the intermediate average pore width (4 nm).
