Unveiling the Concept of Packaging Logistics

Konferensbidrag (refereegranskat)abstract
- An increasingly competitive environment, technological advancements and globalisation are a few of the factors placing higher demands on today’s company activities, e.g. development, production and distribution processes. Company activities have hereby become a complex system, even more so if one company is seen as part of a network of companies. The aim of this article is to present and elaborate on an approach that deals with these matters in an integrated manner – packaging logistics, where the logistics systems are studied from a packaging perspective. This is carried out through putting package definitions and logistics definitions into a model framework based on Porter’s value chain and Christopher’s network theory. Rather than studying packaging and logistics separately, the integrated concept of packaging logistics will give a more complete perspective in problem solving and research. The contribution of this article is to theorise and introduce suggestions to define the subject of packaging logistics.

Tidskriftsartikel (refereegranskat)abstract
- The storage of NOx under lean conditions in model NOx storage catalysts as well as the deactivation by sulphur have been studied. We find that NO2 plays an important role in the storage mechanism as an oxidising agent. Two different mechanisms for this are discussed: the formation of surface peroxides and the oxidation of nitrites to nitrates, FTIR studies show that NOx is stored as surface nitrates, The sulphur deactivation is found to be more severe when SO2 is added during the rich phase than when SO2 is added during the lean period. FTIR shows the formation of bulk sulphates both under lean and rich conditions.
