The glass is considered the raw material that better fits for containers destined to pharmaceutical use. It is an hygienic material: it does not have toxic substance and it is resistant to deterioration.
Small quantities of glass components, melted in the solution inside the container, are neutral and non-toxic, like sodium, calcium and silicon that are elements commonly contained also in mineral water.
One of the numerous glass qualities is its entire recyclability.
Due to its inert nature, this material does not contaminate the environment in which it is placed and it is an ideal material to block eventual dangerous components fused inside and make them inert in its structure.
Unlike other materials, it can be fused endless times so that glass recycle is an complete ecologic process.
The fusion of the waste containers reduces the quantity of raw material necessary to the production of silica sands and calcium carbonate as well as environmental damages coming from pits' exploitation for territory advantage.
Furthermore, it reduces energy consumption; every 1 ton of fused waste glass allows to save 1.2 ton of raw material and about 100 Kilos of combustible.
The use of waste glass in the mixture that is finally transformed into glass decreases the temperature required for glass fusion; as direct consequences: less quantities of combustible and less greenhouse gases, particularly CO2.
Every year in Europe some million tons of combustible oil are saved thanks to glass recycling; some ovens, used for production of green colored containers, take more than 90% of waste glass in the mixture that will be transformed into glass.
CO2 releases are reduced because of the elimination of CO2 as results of carbonate decay.
Those glasses that could not be entirely recycled on fusion (i.e. TV screen, colored glass of cars window) can be used in other ways: in the production of ceramic materials, as fiberglass for thermal insulation, as additive in asphalt production, etc.).
Stevanato Group is taking care of waste valorization in its own plants: glass waste is totally recycled for production of fiberglass for thermal insulation and of ceramic products.
