Oxo-degradable is a term to describe plastic polymers that contain aditives that can help in breaking the material down into smaller pieces that may be more easily biodegradable. s such as polyethylene (PE), polypropylene (PP), or polystyrene (PS)—contain a prodegradant catalyst—often a salt of manganese or iron, and are tested in accordance with ASTM D6954 or BS8472, or AFNOR Accord T51-808, as to their ability to degrade and then biodegrade in the open environment.[citation needed] The prodegradant catalyzes the abiotic degradation process so that Oxo-biodegradable plastic will degrade in the presence of oxygen much more quickly than ordinary plastic.[4]

It is a problemmatic term because it implies a material that biodegrades but infact it describes a type of plastic product that degrades to a certain level, which can actually create microplastics take significantly longer to biodegrade.

polymers such as plastic by an oxidative process. Such degradation breaks down plastic into small pieces that are easier to biodegrad
