Which practice can contaminate recyclable loads and reduce their effectiveness?

Combining different types of recyclables can lead to contamination within recycling loads. When different materials, such as plastics, glass, and metals, are mixed together, it can create complications during the recycling process. Recyclables are typically sorted by type at recycling facilities, and when they arrive mixed together, it becomes difficult to process them effectively. This can result in entire batches of materials being deemed non-recyclable, which wastes resources and reduces the overall effectiveness of recycling efforts. Proper sorting, adherence to local recycling guidelines, and using clear recycling bags help ensure that materials are kept separate, thus maintaining the integrity and quality of the recyclable materials.
