From Waste to Resource: Dow and Google Use AI to Recycle the Unrecyclable

In a pivotal step to improve plastics circularity, global materials science leader Dow has partnered with Google’s X, The Moonshot Factory, to tackle one of the most pressing issues in plastic waste management i.e., recycling hard-to-recycle films and flexibles.

Flexible plastics such as food packaging films are widely used for their lightweight, durable, and protective properties. However, their complex composition, often made of multiple types of plastics combined with other materials, makes them notoriously difficult to identify and sort in current recycling systems. Therefore, only a small percentage of these materials are effectively recycled today.

The objective of this collaborative effort is to transform this scenario by harnessing the power and potential of artificial intelligence (AI) and machine learning to create smarter, more efficient recycling technologies. Dow will contribute its expertise in materials science, while X brings its leading-edge capabilities in machine vision, data modeling, and large-scale computing.

Han Zhang, Global Sustainability Director for Dow’s Packaging and Specialty Plastics division, said, “By combining Dow’s expertise in materials science with Google’s advanced machine learning and AI technologies, we aim to revolutionize the way recycling centers process plastics, making the process more efficient and effective.”

The partnership builds on several years of foundational work by Google X’s Moonshot for Circularity initiative, which has been focused on building a robust, chemistry-based database of plastics used in packaging. The next phase of this initiative will now include films and flexibles, using Dow’s dual role as a producer and recycler of these materials to enhance impact.

The companies have already achieved a proof of concept, demonstrating that AI-powered machine vision tools can accurately identify and estimate the material composition of flexible packaging. This ability to predict material blends in real-time is a breakthrough in sorting technology, which could greatly improve the rate at which these materials are recovered and reused.

X has shared, “We’re encouraged by this proof of concept, and in the coming months, we’ll be continuing our work with Dow to further explore the potential of molecular vision to help address more film and flexible recycling challenges. We aim to enhance recycling systems to better identify, sort, and recycle materials into new packaging products..”
