The pharmaceutical industry is the key player in the healthcare sector but faces significant challenges in terms of sustainability. As the industry evolves with Industry 4.0, integrating green chemistry principles and sustainable practices is imperative. This review explores the intersection of advanced digital technologies and sustainable production, focusing on cleaner manufacturing, green raw materials, and eco-friendly packaging. The adoption of Industry 4.0 technologies such as artificial intelligence, Internet of Things (IoT), and blockchain enhances transparency, efficiency, and environmental impact tracking throughout the pharmaceutical supply chain. Green chemistry approaches, including the use of renewable feedstocks, atom economy, and safer solvents, are discussed as key strategies to minimize the environmental footprint of pharmaceutical production. Additionally, the implementation of green raw materials and innovative packaging solutions is highlighted as a means to reduce waste and promote circular economy practices. This review also addresses the environmental fate and toxicity of pharmaceuticals, emphasizing the need for responsible disposal and waste management. The findings suggest that a comprehensive, technology-driven approach is essential for advancing sustainability in the pharmaceutical industry, ensuring that it can meet both current and future environmental and health challenges.
