Thesis Overview

The project titled "Investigation of the potential use of lignin as a renewable feedstock for the production of value-added chemicals in industrial processes" aims to explore the utilization of lignin, a natural polymer abundantly present in biomass, as a sustainable alternative feedstock for the production of valuable chemicals in industrial applications. Lignin, a complex organic compound found in the cell walls of plants, is primarily a byproduct of the pulp and paper industry and is often underutilized or burned for energy. However, recent research has highlighted the potential of lignin as a renewable and cost-effective resource for the synthesis of high-value chemicals, thereby contributing to the shift towards a more sustainable and circular economy. This study will delve into the various methods and technologies available for the extraction, purification, and conversion of lignin into value-added chemicals such as phenols, vanillin, and aromatic compounds that have applications in the production of plastics, resins, adhesives, and other industrial products. By investigating the properties and chemical structure of lignin, as well as the different processing techniques involved in its conversion, this research aims to provide insights into the feasibility and potential benefits of utilizing lignin as a feedstock in industrial processes. Furthermore, the project will assess the environmental impact and economic viability of incorporating lignin-derived chemicals into existing industrial processes, considering factors such as resource efficiency, carbon footprint, and market competitiveness. By conducting a comprehensive analysis of the technical, economic, and environmental aspects associated with the use of lignin as a renewable feedstock, this study seeks to address the challenges and opportunities in transitioning towards a more sustainable and bio-based chemical industry. Overall, the investigation of lignin as a renewable feedstock for the production of value-added chemicals in industrial processes represents a significant step towards harnessing the potential of biomass-derived resources for a more sustainable and environmentally conscious approach to chemical production. Through this research, valuable insights and recommendations can be generated to facilitate the integration of lignin-based technologies into industrial operations, paving the way for a greener and more resource-efficient future in the chemical manufacturing sector.
