This answer greatly depends on the requirements of your location. For our Casper, WY customers, you are required to separate your materials and instructions for that can be found on the previous link to your location page. For our Sierra Vista, AZ customers, the only items that require sorting are the thin film plastics such as plastic wrap, grocery bags, plastic mailers, etc. For all our other areas, the only items that are required to be separated are the glass items with the additional subscription. The paper, plastic, and aluminum items can go altogether in the mixed Recyclops bags. Please ensure all items are clean from food and other residues when placed out for collection.
