How is paper and cardboard separated from other recyclable materials?

Paper and cardboard are typically separated from other recyclable materials through a combination of manual and automated sorting processes at recycling facilities. Initially, materials are sorted by type using conveyor belts, where workers or machines remove non-recyclable items. After that, specialized equipment like air classifiers and screens can further separate lighter materials like paper and cardboard from heavier items. This ensures that they are processed efficiently and effectively in the recycling stream.
