AI Technical Summary

Technical Problem

Current recycling processes face challenges in efficiently sorting materials based on specific chemical compositions, particularly in achieving precise aggregate chemical compositions in mixed material streams, which is crucial for producing high-quality recycled products.

Method used

A sorting system utilizing a combination of conveyor systems, vision and sensor technologies, including XRF and machine learning algorithms, to classify and sort materials by their chemical composition, allowing for the separation and aggregation of materials into specific chemical compositions, even when individual pieces have varying sizes and shapes.

Benefits of technology

Enables the production of materials with precise aggregate chemical compositions, enhancing the quality and consistency of recycled products by accurately identifying and sorting materials in real-time, even from mixed and irregularly shaped streams.

Abstract

Systems and methods for classifying and sorting materials in order to produce a collection of materials that are composed of a particular chemical composition in the aggregate. The system may utilize a vision system and one or more sensor systems, which may implement a machine learning system in order to identify or classify each of the materials. The sorting is then performed as a function of the classifications.
