Abstract: Ventilated system for the collection and temporary storage of organic waste which comprises a rigid container provided with a plurality of holes and a removable bag inserted in and supported by said container. The bag is supported by the container in a spaced relationship with respect to the ground or the surface on which said container is placed, so that air can flow from the bottom into the bag. The bag is obtained from a breathable biodegradable plastic.

Abstract: Ventilated system for the collection and temporary storage of organic waste, which comprises a rigid container provided with a plurality of holes (10) and a removable bag inserted in and supported by said container. The bag is supported by said container in a spaced relationship with respect to the ground or the surface on which said container is placed, so that air can flow from the bottom (5) into said bag. The bag is obtained from a breathable biodegradable plastic film having a permeability to water vapour higher than 400 g 30 ?m/m Ventilated system for the collection and temporary storage of organic waste, which comprises a rigid container provided with a plurality of holes and a removable bag inserted in and supported by said container. The bag is supported by said container in a spaced relationship with respect to the ground or the surface on which said container is placed, so that air can flow from the bottom into said bag.

Abstract: The biodegradable heterophase compositions comprise partially or completely destructurised and/or complexed starch, a polysaccharide ester and a plasticizer for the polysaccharide ester. In these compositions, the polysaccharide ester constitutes the matrix and the starch the dispersed phase in the form of particles or domains of numeric mean dimension lower than 1 &mgr;m and preferably than 0.5 &mgr;m for at least 80% of the particles. The compositions also comprise an additive which can increase and maintain at values of 4 or more the pH of a solution obtained by placing the compositions in pellet form in contact with water at ambient temperature for 1 hour, with the use of a pellet:water ratio of 1:10 by weight.
