Your soilkind can basically be filled at any time, even during composting. You can add new kitchen waste until the maximum level of the upper chamber is reached. This is determined by the lower edge of the funnel. The capacity of the upper chamber is approx. 2 l. During drying and shredding, the volume of the organic waste is reduced by approx. 80%, so that approx. 10 l of organic waste can be filled in until the chamber is full.
However, make sure not to dispose of too much waste at once to avoid overfilling the chamber.
