Abstract: Cartridge (10) with a filling (12) of at least one substance for preparing a liquid product, said cartridge (10) including a side wall (140), a first end wall (142) through which said liquid product can flow from the cartridge (10) and a second end wall (16) of the cartridge (10) at the opposite side with respect to said first end wall (142), wherein said side wall (140), said first end wall (142) and said second end wall (16) comprise compostable material.

Abstract: A capsule for extraction of a beverage of the filter-coffee type has a capsule body (2), made of water-impermeable material, which defines a chamber (3), present inside which is a precursor of the beverage, comprising soluble coffee and roast and ground coffee. At least 51 wt % of the precursor is roast and ground coffee having a grain size expressed in x50 comprised between 350 and 800 ?m, and the complement to 100 wt % of the precursor is soluble coffee having a grain size expressed in x50 comprised between 1000 and 5000 ?m. The roast and ground coffee is laid out to form a first layer (GC) in the lower part of the capsule body (3), and the soluble coffee (SC) is laid out to form a second layer (SC) in the upper part of the capsule body, i.e., in a position corresponding to the inlet wall (5) and/or above the first layer (GC).
