Used smartphone (market for)

The activity generating the emissions is market for used smartphone. The reference product is used smartphone. Used smartphone is a solid waste under the category of industrial wastes. It is primarily generated in end-of-life of smartphone. used smartphone contain the following fractions: electronics scrap, iron, copper, battery, plastic from consumer electronics, glass, liquid crystals. By the database default (and per unit of reference product),used smartphone has 0% water on wet mass basis (100% dry matter) and Carbon present is of both fossil (15.65% on a dry matter basis), and non-fossil origin (0.01% on a dry matter basis). It has no heating value. This kind of by-product (recyclable or waste) is generated from ordinary transforming activities, and as such can be considered for modelling waste outputs of comparable composition. In the ecoinvent database, this by-product is used in the following processes: treatment of used smartphone, mechanical treatment. Based on the aforementioned treatments, this by-product receives, it is a non-hazardous waste. This by-product can be modelled on two levels: treatment activity and market activity. The former one refers to the specific technology treating the by-product while the latter level represents a mix of treatments. Users are encouraged to inspect the modelling assumptions of the treatment activities and when selecting the market to additionally inspect the treatment mix. Collection and transportation of this by-product is accounted in the respective market activity, users are advised to inspect and modify the average transportation distances for a case specific modelling. The reference product amount is -1. The cut-off classification is Waste. The activity type is ordinary market activity.
