The present invention relates to a system (100) for preparing compostable capsules (900) for brewing products. Wherein the capsule (900) is made of a sheet (600) made of a biodegradable cellulose-based material. The system (100) comprises at least one forming line (200) comprising a handling unit (300) for conveying a sheet (600) through the system (100) in a conveying direction (TD). The forming line (200) further comprises a humidification unit (400) for wetting at least one side of the sheet (600) with a wetting agent (401), and a forming unit (800) for forming a portion of the wetted sheet (600) into a three-dimensional shape to form an encapsulation element (910) defining an encapsulation cavity (911). The portion (642) is located between opposite lateral side edge sections (631, 632) of the sheet (600) with respect to the transport direction (TD). The forming line (200) further comprises a transverse drying unit (500) arranged to dry the opposite transverse side edge sections (631, 632) of the wet sheet (641) while keeping at least the portion (642) to be formed wet. Wherein the transverse drying unit (500) is arranged downstream of the humidifying unit (400) and upstream of the forming unit (800). The invention also relates to a method for preparing a compostable capsule (900) in which the opposite lateral side edge sections (631, 632) of a wet sheet (641) are dried while at least the portion (642) to be formed is kept wet prior to forming the portion (642) of the wet
