In 2022, the commercially most important types of bioplastics were PLA and products based on starch. [14] With continued research on bioplastics, investment in bioplastic companies and rising scrutiny on fossil-based plastics, bioplastics are becoming more dominant in some markets, while the output of fossil plastics also steadily increases.
Cellulose acetate fiber, one of the earliest synthetic fibers, is based on cotton or tree pulp cellulose ("biopolymers"). These "cellulosic fibers" have been replaced in many applications by cheaper petro-based fibers (nylon and polyester) in recent decades. [6] Trade names for acetate include Acele, Avisco, Celanese, Chromspun, and Estron. [7]
The polluting effects of carbon disulfide and other by-products of the process used to make viscose may have also contributed [citation needed] to its falling behind lower cost petrochemical-based films such as biaxially-oriented polyethylene terephthalate (BoPET) and biaxially oriented polypropylene (BOPP) in the 1980s and 1990s. However, as ...
Biologically-based polymers, sourced from non-fossil materials, can decompose naturally in the environment, whereas some plastics products made from biodegradable polymers require the assistance of anaerobic digesters or composting units to break down synthetic material during organic recycling processes.

Rayonier Advanced Materials recently rebranded as RYAM.RYAM is an American company recognized globally for its cellulose-based technologies. Specializing in high-purity cellulose specialties, [3] RYAM produces natural polymers extensively used in manufacturing filters, food, pharmaceuticals, and various industrial applications.
Some companies like Kind focus on using as many plant-based ingredients as they can. Almost all the brands we tested had plastic-free packaging. Almost all the brands we tested had plastic-free ...
