Used desktop computer (treatment of - manual dismantling)

The activity generating the emissions is treatment of used desktop computer, manual dismantling. The Reference Product is used desktop computer. Used desktop computer is a solid waste under the category of industrial wastes. It is primarily generated in end-of-life of desktop computer. used desktop computer contain the following fractions: used capacitor, batterry and plastic from consumer electronics. By the database default (and per unit of reference product),used desktop computer has 0% water on wet mass basis (100% dry matter) and Carbon present is of both fossil (8.78% on a dry matter basis), and non-fossil origin (0.05% 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, treatment option/s for this by-product include: manual (dismantling). Based on the aforementioned treatments, this by-product receives, it is a non-hazardous waste.
