His firm -- North Side-based United Oil Co. -- had been successfully producing industrial lubricants since 1906 and his initial research suggested that producing biodiesel would require a major retooling of the plant.
But when the United Oil president discovered it would not take as large a capital investment as he thought, the company took the plunge last December and began producing fuel made primarily from animal fats. In its first year as a biodiesel producer, the company saw its overall sales triple, leading Mr. Cross to increase annual production capacity to 5 million from 1.5 million gallons and hire two employees, boosting his work force to six.

"Pittsburgh has all the things you need," he said: research universities, charitable foundations with an interest in alternative energy, affordable housing and brownfields that have and can become manufacturing sites.
