Hollow glass is used mainly to make packaging or table glassware: bottles, jars, drinking glasses, crockery, etc., so it is part and parcel of our daily life.
Glass can be of household origin, from everyday household consumption, or industrial (from glass manufacturers or bottlers). We refer to such glass as production scraps.
The most annoying type of pollution in raw glass consists of infusible bodies: plates, porcelain cups, earthenware, ceramics, etc.
Plugs, plastics, and metals are other types of pollutants to be extracted from the glass stream.
