An oil and grease absorbent composition contains comminuted sphagnum moss as a major ingredient and, as a minor ingredient, a sufficient amount of powdered calcined gypsum to render the mixture fire resistant. A minor amount of a lightweight friction material is also desirably added. A preferred composition is approximately 12 parts by volume of comminuted sphagnum moss and approximately 1 part each by volume of powdered calcined gypsum and heat expanded perlite.
