original ecoinvent name: Packaging glass, white {RER w/o CH+DE}| packaging glass production, white | Cut-off, S

This dataset represents the production of 1 kg of white packaging glass from a mix of primary and secondary raw materials.

[This dataset was already contained in the ecoinvent database version 2. It was not individually updated during the transfer to ecoinvent version 3. Life Cycle Impact Assessment results may still have changed, as they are affected by changes in the supply chain, i.e. in other datasets. This dataset was generated following the ecoinvent quality guidelines for version 2. It may have been subject to central changes described in the ecoinvent version 3 change report (http://www.ecoinvent.org/database/ecoinvent-version-3/reports-of-changes/), and the results of the central updates were reviewed extensively. The changes added e.g. consistent water flows and other information throughout the database. The documentation of this dataset can be found in the ecoinvent reports of version 2, which are still available via the ecoinvent website. The change report linked above covers all central changes that were made during the conversion process.]

CO2 emissions have been recalculated from the carbon content in raw materials and fuels.

Material inputs are estimation based on literature sources and a Swiss production site. Energy and water consumption, emissions, and waste production are estimation based on literature sources. Infrastructure is an estimation based on average European packaging glass factories.

Production volume: 12807795712 kg
Included activities start: From the reception of precursors silica sand, soda, unsorted glass cullets, limestone, dolomite, feldspar, and chemicals  inorganics at the factory gate.
Included activities end: This activity ends with the production of 1 kg of white packaging glass. The dataset includes material and energy inputs, water consumption, emissions to air and water, waste production, transport and infrastructure.
Energy values: Undefined
Geography: The inventory is modelled for Europe without Germany and Switzerland
Technology level: Old
Technology: Packaging glass is produced in a two stage moulding process with pressing and blowing techniques. The whole process is fully automatic and consists of five different stages:

None

1.	Production of a molten glass piece (gob) with correct weight and temperature. 

None

None

2.	Forming of the primary shape in a first mould (blank mould) with compressed air pressure

None

3.	Transfer to the final mould (finish mould)

None

4.	Bringing the shaping process to an end by blowing the container with compressed air until the shape of the final mould

None

5.	Post forming processes

The melting process is the central one. As the first glass forming material, sand, has a very high melting point. Soda as a fluxing agent is used to reduce the melting temperature. When heating soda, this is decomposed into sodium oxide Na2O, the actual fluxing agent, and into carbon dioxide that is released. Metal oxides in form of limestone (CaCO3 that decomposes to CaO), dolomite (-> Ca- and Mg-Oxides), feldspar are used as stabilizators and therefore to improve the hardness and chemical resistance of glass. For white glass  decolouring agents are added.
