The swings in the demand of supply of feedstock availability and pricing add uncertainty to the Petrochemical industry, and make planning and capital investment decisions more difficult. The reliance on a single feedstock type could be the lowest cost and simplest to manufacture, but lead to lost opportunities as other hydrocarbon sources emerge on the market. In particular, the increase in natural gas availability in the last decade has offered a surprising and non-traditional feedstock to producers. Petrochemicals, as with all chemical industries, faces demands for more environmentally-friendly manufacturing processes. In a competitive industry with ambitious companies operating around the world there is a strong need to continually make processes more cost effective.
