A method for manufacturing a compostable pod for brewing products envisages preparing a first and a second sheet made of biodegradable material with gas barrier properties, shaping the first and the second sheet so as to make at least a first and a second concave portion, filling the first concave portion with a predetermined quantity of brewing product and joining the first concave portion to the second concave portion so that the respective concavities are opposite one another and define a casing for the brewing product. The shaping steps of the first and the second sheet envisage moistening at least a first portion of the first sheet and a second portion of said second sheet, configuring the first and the second portion so as to make the first and the second concave portion and drying the first and the second concave portion.
