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.
