Synergistic Effects on Properties of Biofuel and BiocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More Produced through Co-Feed PyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More of *Erythrina Indica* and *Azadirachta Indica* BiomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally.

In the quest for sustainable energy solutions, the co-feed pyrolysis of Erythrina indica (EI) and Azadirachta indica (AI) presents a promising avenue. This innovative technique, performed at a temperature of 600°C under nitrogen atmosphere, investigates the effects of different biomass ratios on the yield and quality of biofuels. The study explores co-feed ratios ranging from 1:4 to 4:1, finding optimal results at a 1:1 ratio, which notably enhances the physicochemical properties of the pyrolysis products.

At this balanced ratio, the peak calorific value of bio-oil soared to an impressive 36.80 MJ/kg, with the density dipping to a mere 0.82 g/ml, closely mirroring commercial gasoline standards. This specific ratio not only maximizes the heating value but also reduces the density, making the bio-oil a competitive alternative to traditional fuels.

The biochar output from the 1:1 ratio showcased a high carbon content of 79.23 wt.% and a heating value of 29.23 MJ/kg. This makes it an excellent candidate for solid fuels, besides its potential as a soil conditioner due to its porous nature. The gas composition from this process was also noteworthy, consisting of 7.45% hydrogen, 34.26% carbon monoxide, 21.32% methane, and 36.97% carbon dioxide, indicating a robust mix for further energy recovery.

This study not only demonstrates the feasibility of using EI and AI for high-quality biofuel production but also emphasizes the benefits of selecting the right biomass ratios. The synergistic effects observed at a 1:1 ratio lead to superior fuel characteristics, paving the way for a more sustainable and economically feasible biofuel production method. By harnessing the inherent properties of these biomasses, the co-feed pyrolysis method marks a significant step forward in the renewable energy landscape, offering a potent solution to the global energy crisis while aligning with environmental sustainability goals.
