The invention concerns a method for manufacturing a compostable pod for brewing products, comprising the following steps:- preparing a first (2) and a second sheet (3) made of biodegradable material with gas barrier properties;- shaping said first sheet (2) such as to make at least a first concave portion (2a);- shaping said second sheet (3) such as to make at least a second concave portion (3a);- filling the first concave portion (2a) with a predetermined quantity (4) of brewing product;- joining said first concave portion (2a) to said second concave portion (3a) so that the respective concavities are opposite one another and define a casing for said brewing product;in which the shaping steps of the first (2) and of the second sheet (3) envisage:- moistening at least a first portion of said first sheet (2) and at least a second portion of said second sheet (3);- configuring and simultaneously drying the said first portion using a first configuration device, so as to make said first concave portion (2a);- configuring and simultaneously drying said second portion using a second configuration device, so as to make said second concave portion (3a).The invention also proposes a machine for making compostable pod for brewing products as well as a shaping station for a machine for making compostable pods for brewing products.
