Over many years, the petrochemical industry has built up an effective infra- structure for processing and distributing hydrocarbon-based products. Due to reliance on imported crude oil, much of the . infrastructure is geographically located around the coastline (Fig. 9). Thus, many current processing facilities are not well situated for the collection of large volumes of plant-derived material. Where plant materials are processed in lumber mills, oil crushers, or corn wet mills, these are situated adjacent to areas of supply. A transition to more plant- derived materials will require further integration of supply and processing/ manufacturing. An example of the new infrastructure is the manufacturing facil- ity being built in.
