One current opinion maintains that greater containerization could help generate additional cargo for container shipping. It is argued that unconventional commodities can be carried increasingly in containers. These include, for example, larger volumes of scrap steel and recycled paper from North America and Europe to Asia, and general cargo and bulk commodities that can be transported in smaller batches and containerized (for example, segments of food commodities and raw material). Other commodities include more refrigerated cargo, chemicals and even Handysize loads of bulk commodities, such as iron ore, which is reported to have already been shipped in small parcels from Africa to China. For these ideas to materialize, however, prevailing price and cost barriers need to be removed and cost-effectiveness and vessel specifications need to be assessed.
