Sustainability has many definitions. The most common definition of sustainability has its roots in a 1987 United Nations conference, where sustainability was defined as “meeting the needs of the current generation without compromising the ability of future generations to meet their needs” (WCED 1987). Sustainable materials, processes, and systems must meet this definition and not compromise the ability of future generations to provide for their needs while providing for the needs of the current generation. Thus, for plastics manufacturing, materials and processes used today should not deplete resources for future generations to produce plastic materials.
