market for waste polyethylene, UPR, ecoinvent 3.6, Undefined
Location: CH - Switzerland
This market dataset models the disposal mix for 1 kg of waste polyethylene in Switzerland using country-specific data. The mix is composed by the following technologies: 0% of open burning, 1% of open dump, 99% of municipal incineration. Values are rounded without decimals. If a technology is listed, it participates in the technology mix. The transport from the production site of the waste to the different treatment facilities where the waste is treated is accounted here. Collection of the waste is included in the transport estimate, reflecting transport distances from eurostat. There are no losses considered in the dataset.

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.
The dataset supplies a disposal mix (technology mix) of waste polyethylene to the respective waste producing activities.
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.
