In the logistics sector, major opportunities for reducing costs and sparing the environment can be extracted from bundling. A tangible example: a fully loaded truck makes a delivery but returns empty. Can nothing be transported for another shipper on the return journey? 4C is just one of the TKI Dinalog roadmaps with which projects are initiated to take this type of collaboration forward. This is all about bundling and managing physical flows of goods, flows of information, financial flows and data management.
