Emerging trends in Sustainability Engineering and the Circular Economy are reshaping industries to prioritize resource efficiency, waste reduction, and regenerative processes. Innovations in recycling Technologies, such as chemical and enzymatic recycling, are enabling the recovery of high-quality materials from waste, especially in textiles and plastics. There is also a shift towards biomimicry, with biodegradable and nature-based materials gaining prominence. Closed-loop supply chains and circular business models like product-as-a-service are driving the adoption of systems that minimize waste by reusing Materials and extending product lifespans. Additionally, digital solutions like blockchain and AI are enhancing supply chain transparency and optimizing resource use. Governments and industries are increasingly aligning policies and regulations, such as extended producer responsibility (EPR) and circular economy action plans, to accelerate the adoption of sustainable practices. These trends collectively aim to decouple economic growth from resource consumption, fostering a more resilient and sustainable global economy.
