The efficiency of indigenously manufactured polyurethane foams and dispersants in the removal of spilled oil

Abstract

The absorbing capacities of a brand of Indian polyurethane foam and four different indigenous dispersants were tested in the laboratory using spills of heavy furnace oil. Polyurethane foam was found to absorb about 100% its own weight of oil. It could be reused after the oil was squeezed from it. The dispersants were effective in removing the oil completely if these were used with oil in the ratio of 1:1. Of the 4 dispersants tested, one was found to be non-toxic and this particular brand was found to be most effective
