Abstract
A multipurpose compostable absorption mat serves to receive and encapsulate organic matter for compostable disintegration of the mat and organic matter simultaneously. The mat comprises at least three portions: a first portion facing the organic matter defined by a parchment paper or parchment-like material having multiple pinholes or other openings or porosity sized and dimensioned to enable passage of greases and/or liquids; a second portion outboard of the first portion defined by a deliquescent material, and is able to absorb the greases and/or liquids from the first portion through a capillary mechanism; and a third portion outboard of the second portion defined by an impermeable plant/corn starch-based plastic-like material. The third portion looks and feels like plastic film. The at least three portions of the mat may be formed as at least three discrete layers, with the three discrete layers attached to one another so as to form the mat, with the mat having a thickness in the range from about that of a sheet of paper or a paper towel or a napkin to about ¾″ or more.
