I have a question regarding flows of products. If i for example produce a bottle and I need two products: plastic and paper. And i create those products with all the associated flows (so resources, emissions etc) for both the products (plastic and paper). If i then make a new product for the bottle and I use as input the flow of plastic and paper, are then all the revelant input- and output flows from those two products calculated in the final product? Or do i have to add them again?
