This hub has a significant supply chain integration, accounting for 10% of the total Portuguese chemical industry. Methylene Diphenyl Diisocyanate, or MDI, is the most important output and is produced mainly for export.
Nitric Acid, nitrobenzene, aniline, hydrogen, carbon monoxide and chlor/alkalis, are also produced in this hub by different companies. Large quantities of these products are used in the production chain of MDI, but external sales are also significant. The output of this hub includes other less important products associated with the above main products.
Also located in the same area are other chemicals plants such as PVC and urea-formaldehyde resins.
One of the main raw materials, benzene, comes from a refinery located in Matosinhos (Oporto), about 45 kilometers (km) away. Other raw material, ammonia, is brought by rail from the Lisbon area (300 km), while vinyl chloride monomer (VMC) comes by pipeline (25 km) from the port of Aveiro.
This hub is considered an efficient site, mainly export-oriented, with good links to universities mainly Aveiro (about 20 km away), Porto (40 km) and Coimbra (80km).
Concerning logistics, the hub uses the port of Aveiro (25 km), railways and a motorway junction (enabling connections with the whole of Portugal, Spain and Europe). There are some points which can be improved, such as the transport of benzene and the railway connection with the harbour of Aveiro.
The strong dependency on one output (MDI) is the weak point of this hub, limiting the development strategy.
