2022 will be the International Year of Glass. That was established by the United Nations General Assembly. In a resolution, the United Nations (A/RES/75/279) writes that "2022 will highlight the technological, scientific, economic, environmental, historical and artistic role of glass in our society, highlighting the rich possibilities of developing technologies and their potential contribution to addressing the challenges of sustainable development and inclusive societies, achieving global economic recovery and better rebuilding from the coronavirus epidemic." The sustainability of glass, which is infinitely reusable and recyclable, is demonstrated by data: in 2020, the year of the pandemic, glass recycling in Italy reached 79% (it was 77% the previous year), well above the European target of 75% set for 2030. The industry's commitment is to reach 90% by acting on collection, treatment and recycling.

Even though we talk about the importance of recycling all the time, it should be remembered that not all materials are recyclable and, among them, the rate of recovery of secondary raw materials and the types of use of the same can vary enormously. Even from this point of view, glass is an extremely virtuous material: in fact, it is potentially infinitely recyclable. Glass - together with steel and aluminum - is in fact defined as a permanent material.
