9. How do you recover the value of secondary assets in the return chain? A non-exhaustive list of the types of assets recovered on the secondary market (figure 4) is as follows: 1. Returns, bankruptcy, products past their use-by date, overstock, unsold products. 2. Returns, end of series, unsold items. 3. Second hand. Rogers and Tibben-Lembke [1] confirm that the choice of the backward logistic network depends on two parameters: the choice of the value-added channel to which the secondary asset is redirected; the degree to which the secondary asset has been processed for reintegration into a value chain.
