Description

Location: ZA - South Africa
Local market data set for South African conditions based on the local production of cement.
1.2% of the cement is transported -using rail whereas 98.8% by road. Source: Department of Minerals and Energy SA (2005), Dolomite and Limestone in South Africa: Supply and Demand, Report R49/2005. Transport distances are ZA specific and represent weighted average data calculated from 2 cement production plants which represent 8% of the market share as of 2017. The data do not include exports by these cement plants or imports.

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.
