1. System for manufacturing a compostable pod for brewing products from a sheet made of a biodegradable cellulose-based material, the system comprising at least one shaping line, which comprises:
a handling unit for transferring the sheet along a transfer direction through the system;
a humidifying unit for moistening at least one side of the sheet with a moistening agent; and
a forming unit for shaping a part of the moistened sheet into a three-dimensional shape to form a pod element defining a pod cavity;
wherein the at least one shaping line further comprises:
a humidity sensor system for visually sensing a level of humidity of at least a section of the moistened sheet, and
a control unit configured to receive values related to the level of humidity sensed by the humidity sensor system, and to control the humidifying unit based on these values.
