Filament winding

The activity generating the emissions is filament winding. The reference product is filament winding. This is delivering the service of "filament winding". Filament winding is a technique used to manufacture hollow, circular, or prismatic parts such as pipes and tanks. It is performed by winding continuous fibre tows onto a rotating mandrel using a specialized winding machine. 1 kg of this process corresponds to 0.94 kg of the final product at the end of the process. The converted amount of material (fibres and resin) is not included into the dataset. The user should list 1 kg of the service and 1 kg of the resin and fibre INPUT for an OUTPUT of 0.94 kg of material processed. If an activity requires 1 kg of wounded product, the user should list (i) 1/0.94 = 1.33 kg of the service and 1.33 kg of the resin/fibres type processed. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
