We usually talk about the benefits for the environment brought about by us recycling waste, but how much are we talking about? Is recycling really good for the environment?

Glass is an inorganic material that is obtained mainly from silica sand (SiO2, around 70%), calcium carbonate (Ca2CO3, around 15%), limestone (CaCO3, approximately 10%) and other additives, by melting at about 1,500 ºC (2,732 ºF).
According to different sources, glass was first manufactured around the year 3500 a.C. in Egypt other sources indicate its origin to be2500 a.C. in Mesopotamia– as a decorative element, and its different uses have evolved. Thus, glass has been used to manufacture vessels, windows and nowadays, above all, for packaging, specifically for liquids, since it’s a type of packaging that neither interferes nor alters the taste of its contents. We have been manufacturing glass for the last 4,500 years, at least.
“Recycle” comes, etymologically speaking, from the Greek word kýklos, which means “orbit or circle,” and by extension, “ordered repetition or recurrence of phenomena.” In Latin, the term becomes cyclus-cycli, adding the prefix: “Re.” (which means repetition).
