[ We claim:] [1.] An absorbent article for collecting a non-aqueous liquid comprising a low density, hydrophobic, structurally integral board of peat moss material manifesting an affinity for the non-aqueous liquid, wherein said board of peat moss material is capable of absorbing the non-aqueous liquid under the effect of capillary pressure. [14.] A method for manufacturing a low density, structurally integral article for collecting a non-aqueous liquid, said method comprising the steps of:a) forming a liquid suspension of peat moss material;b) sheeting said suspension on a layer of fibers;c) extracting fluidizing medium from said suspension to form a low density board of peat moss material to cause said fibers to adhere to said peat moss material;d) drying said board of peat moss material at a temperature above 100.degree. C. to evaporate residual moisture;said method being completed without conditioning said peat moss material with wetting agent to preserve a natural hydrophobicity of the peat moss material in order to impede water penetration in the article. A method as defined in claim 14, comprising the step of forming an aqueous slurry of peat moss material to form said suspension. A method as defined in claim 14, comprising the step of classifying said peat moss material to eliminate therefrom particles having a size smaller than 210 microns and particles having a size larger than 2000 microns. A method as defined in claim 15, comprising the step of depositing over said suspension in sheeted form a layer of fibers, whereby the extraction of fluidizing medium from said suspension causes said fibers to adhere to said peat moss material. A method as defined in claim 17, wherein said fibers are selected from the group consisting of Kraft pulp fibers, ground wood, cotton linters and mixtures thereof. A method as defined in claim 14, comprising the step of combining with said peat moss material a component selected from the group consisting of polyester, nylon, acrylic, Kraft wood pulp, mechanical wood pulp, cotton linters, jute and mixtures thereof.
