When it comes to batch composting, dry leaves and kitchen scraps are included in the compost bin till it is full. After that, nothing more is added to the material breaks down. The process of decomposition and composting can take up to 2 months. With accessible bins, the compost needs to be turned at least once a week so that there is proper ventilation inside the compost bin, and it does not smell. One needs at least two bins in batch composting. So, this is to ensure that one remains active while the other one can be closed while composting takes place. Generally, this is the way how most of the compost tumblers and wooden bins work.
