As is the case for disposable cups, materials used are usually paper, plastic (including expanded polystyrene foam), or plastic-coated paper. Recycling rates are especially low for paper-based products, especially when soiled with (wet and / or oily) scraps due to diminished recyclate quality.
Disposable foodservice products made from paper, paperboard, and corrugated fiberboard include cups, plates, bowls, napkins, carryout bags, trays, egg cartons, doilies and tray liners. Some paper products are coated - mostly with plastic - or treated to improve wet strength or grease resistance. Paper and paperboard packaging like pizza trays ...
Disposable products are most often made from paper, plastic, cotton, or polystyrene foam. Products made from composite materials such as laminations are difficult to recycle and are more likely to be disposed of at the end of their use. They are typically disposed of using landfills because it is a cheap option.

A found object (a calque from the French objet trouvé), or found art, [1] [2] [3] is art created from undisguised, but often modified, items or products that are not normally considered materials from which art is made, often because they already have a non-art function.

The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York, in 1907, and patented on December 7, 1909. [3] Bakelite was one of the first plastic-like materials to be introduced into the modern world and was popular because it could be moulded and then hardened into any shape.
Plastic composites or proprietary blends can be more difficult to identify. If there are no markings to identify the type of plastic used, it may still be identified by using various types of spectroscopic technology such as optical spectrometer, Raman mid-infrared spectroscopy, [4] and near-infrared spectroscopy, along with mass spectrometry.
