Green Chemistry & Biofuels

This document presents a comprehensive set of adapted case studies for the course Introduction to Process Engineering at Polytech Diamniadio, Universit Amadou Mahtar Mbow. It is based on the ACS Green Chemistry Institute (ACS GCI) Module E.2 and contextualized for the Senegalese industrial environment. The material focuses on the integration of green chemistry principles, sustainability metrics, and biofuel technologies into undergraduate engineering education. The document contains four detailed case studies with complete solutions and numerical calculations related to green chemistry metrics such as the E-factor, atom economy, and Reaction Mass Efficiency (RME). The scenarios compare fossil-based and bio-based industrial processes using real Senegalese industrial actors including SAR, CSS, SUNEOR, and SODEFITEX. Topics addressed include biodiesel production from jatropha, ethanol production from molasses and bagasse, solvent substitution in oil extraction, lignocellulosic biomass valorization, process safety, life cycle thinking, and sustainable development goals (SDGs). Designed for Licence 2 students in Process Engineering, the document promotes critical thinking, problem-solving, and sustainability assessment through locally relevant industrial examples. It also demonstrates how green chemistry concepts can be embedded into process engineering education using active learning and case-based pedagogy.
