Description

Location: DE - Germany
This dataset represents the production of 1 kg of refractory fireclay bricks.
Includes the whole manufacturing process, internal processes (transport, etc.), packing and infrastructure. No administration is included.
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.

Technology

The typical German technology for refractory fireclay production.
For the production of one ton of fireclay refractory 1.1 ton of chamotte and additionally 10% of clay (0.1 ton) is required. This results in a total amount of 1.2 kg clay for 1 kg of fireclay refractory. The raw materials are fractionated in different coarse size groups and one or several flour components. The grains and flours are mixed in a certain share and a fixing agent (lime milk) is added. The mixture is pressed to bricks, which are baked at 1200 to 1800°C.
Chamotte is burned and milled clay.
