These virtual replicas of equipment, systems, or entire factories simulate real-world conditions, delivering actionable insights without the cost or waste of physical experimentation.
For example, a packaging company looking to adopt a more sustainable material can use a digital twin to simulate how the material behaves during production. This approach helps identify potential issues and refine processes without wasting resources on trial-and-error methods in the physical world.
An automotive manufacturer has taken digital twins even further by replicating entire assembly lines. This allowed them to fine-tune workflows, cut material waste, and boost energy efficiency, achieving a 15% reduction in resource use while also speeding up the launch of new models. Digital twins are transforming manufacturing by enabling smarter, more sustainable decision-making with measurable results.
AI: Smarter Decisions for a Greener Future
Artificial intelligence (AI) is essential for turning the massive data generated by IoT sensors and other sources into actionable insights. AI systems identify patterns, predict outcomes, and recommend steps that drive more sustainable and efficient operations.
For instance, a global food processing company leveraged AI to optimize its energy-intensive refrigeration systems. By analyzing factors such as external temperature, production schedules, and energy costs, the AI made real-time adjustments, reducing energy consumption by 30% while maintaining food safety standards.
AI is also revolutionizing supply chains by improving demand forecasting. With better predictions, manufacturers can align production more closely with actual needs, reducing overproduction and minimizing waste. In industries like apparel, where unsold inventory often ends up discarded, this approach can significantly cut waste and boost profitability.
