Description

Location: BR - Brazil
This is a constrained market for GBFS, which is further grinded and added to cement as a clinker replacement. The justification for a market constraint is included in the comment field of the conditional exchange.
Transport distance was measured from all the 32 steelmaking factories associated to the Brazilian Steel Institute to the 56 cement making factories associated to the Brazilian Portland cement Association that actually manufacture slag cement. The underlying assumption was that cement making factories bought granulated blast furnace slag from the closest steelmaking factory (this was confirmed by sector experts). The average distance is 159.22 km, but high uncertainty is associated with it.
Lorry's size was defined as 16-32t based on the average amount of granulated blast furnace slag generated in the country and transported daily. Considering the number of investigated steelmaking factories, around 640 ton of GBFS leave each factory, every day, which would require a lorry able to transport elevated loads.
EURO 3 emission standard (equivalent to PROCONVE 5) is assumed to represent 45% of Brazilian road cargo fleet, according to the inventory of road transport vehicles in 2013.

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

This dataset represents a market activity in the ecoinvent database. A market activity is an activity that does not transform inputs, but simply transfers a specific intermediate exchange (i.e. products, including wastes and by-products) from supplying transforming activities to other transforming activities that demand this intermediate exchange as an input, e.g. from glycerine at the supplier to glycerine at the consumer. A market dataset collects all activities with the same reference product in a certain geographical region. Furthermore, it typically includes average transport requirements for that product within the geography in question, as well as inputs of the product itself to cover any losses in trade and transport. In other words, market activities are generally intended to represent consumption mixes of a given product in a certain geographical region.
