<p>Objective: the objective of the present invention lies in shortening the compost preparation period by a simple method and preventing contamination of underground water. Constitution: film for accelerated compost fermentation which is characterized in that it comprises a composition in which the chief component is polymer containing polyether chains as structural units, and where the water vapour permeability thereof is at least 300 g/m2.24h, the oxygen permeability is at least 1,000 cm3/m2.24h.atm and the carbon dioxide permeability is at least 10,000 cm3/m2.24h.atm; together with film for accelerated compost fermentation which is characterized in that the aforesaid film is reinforced by means of a nonwoven material or net.</p> |
