The global population growth and increasing energy demands are driving the need for sustainable energy sources to preserve fossil fuels and ensure a stable energy future. Bioenergy, particularly biodiesel, has gained attention as a promising alternative to conventional diesel due to its environmental benefits and potential for using waste materials. Biodiesel is recognized for its ability to reduce greenhouse gas emissions, improve air quality, and promote energy independence by utilizing domestic resources, including agricultural waste and recycled materials. Homogeneous catalysts are commonly used in biodiesel production; however, they can be difficult to recover. Lignocellulosic biomass, derived from dried plant materials, is being explored as a renewable and low-cost feedstock. Biodiesel's combustion has been shown to release lower levels of harmful pollutants compared to petroleum diesel, contributing to its appeal. Research indicates biodiesel's compatibility with existing diesel engines, with advantages such as better lubricity and ignition quality. Recent studies have focused on alternative sources for heterogeneous catalysts in biodiesel production, including the plantain peduncle, which has been found to exhibit good thermal stability and catalytic activity. Additionally, lard oil has been identified as a valuable feedstock for biodiesel synthesis, albeit with potential cold flow issues due to its high saturated fatty acid content. Current research aims to extract bio-oil from used lard oil, improving extraction methods to produce feedstock suitable for biodiesel manufacturing. Update (2024-11-25): The growing global population and rising energy demands highlight the urgent need for a transition to sustainable energy sources to prevent fossil fuel depletion and secure a stable energy future. Bioenergy, especially biodiesel, is gaining attention as a viable alternative to conventional diesel due to its environmental benefits and potential to utilize waste materials. Biodiesel is recognized for its ability to reduce greenhouse gas emissions and harmful pollutants, while also offering advantages such as biodegradability and lower environmental risks. Moreover, it can enhance energy security by decreasing reliance on imported fossil fuels and promoting local economic development. Though traditional homogeneous catalysts are effective in biodiesel production, they present challenges in recovery. As a solution, research is exploring the use of lignocellulosic waste and low-cost heterogeneous catalysts, such as those derived from plantain peduncle, which demonstrate good catalytic properties. Lard oil is also being investigated as a feasible feedstock for biodiesel synthesis. However, commercial biodiesel production faces hurdles, including toxicity, corrosion, and high production costs driven mainly by feedstock prices, leading to a competitive disadvantage against petroleum diesel. This study aims to explore the effects of hybrid feedstocks and catalysts on biodiesel synthesis, with specific objectives to evaluate their impact on product outcomes, compare the compositions resulting from different blends, and analyze the benefits and challenges of integrating these into production processes. The research encompasses a detailed examination of various hybrid feedstocks and catalyst performance, considering factors like greenhouse gas emissions and economic feasibility to provide a comprehensive assessment of biodiesel production's sustainability. The study emphasizes the importance of hybrid feedstocks and catalysts in enhancing the efficiency and viability of biodiesel synthesis, contributing to the advancement of sustainable biofuel technologies. Update (2024-11-25): The increasing global population and energy demands highlight the need for sustainable energy solutions to prevent fossil fuel depletion and ensure energy stability. Bioenergy, particularly biodiesel, is gaining attention as a viable alternative to conventional diesel due to its environmental benefits and ability to utilize waste materials. Biodiesel is recognized for its potential to combat global warming, reduce greenhouse gas emissions, and improve air quality, while also enhancing energy security by reducing reliance on imported fossil fuels. Despite the promising qualities of biodiesel, its commercial production faces challenges such as toxicity, corrosion, and wastewater generation, which raise economic feasibility concerns. Feedstock issues, particularly the competition between food and energy production, continue to hinder widespread adoption. The study aims to address these challenges by exploring the effects of hybrid feedstocks and catalysts on biodiesel production processes. The specific objectives include evaluating the impact of different feedstocks and catalysts on biodiesel yield and composition, while also examining the environmental sustainability and economic viability of production methods. The scope involves analyzing various hybrid feedstock combinations and their performance with catalysts during transesterification, although optimizing the transesterification process itself is not included in this research. The justification for this study lies in its potential to uncover alternative feedstocks and catalysts that can improve the efficiency and sustainability of biodiesel production, ultimately contributing to the diversification of the biofuel industry and addressing both environmental concerns and economic feasibility.
