The life cycle of plastics consists of several stages. There are two phases that have the greatest impact on the emission of polluting gas, which Plastisac, for example, does not deal with directly: raw material and end-of-life. The former includes the process of procurement and production of the raw material, while the latter includes the collection and disposal of the finished product. With a virtuous and circular process such as that which is in Plastisac's mission, the use of new raw materials and end-of-life will be drastically reduced.
