Composting in winter

 

If you are composting biowaste throughout the year, you need a thermally insulated composter. In the Biolan Quick Composter a urethane layer five centimetres thick also covering the bottom takes care of keeping in the heat. The presence of thermal insulation does not mean that the outside air temperature would not affect the temperature of the composter. As the weather gets cold, the composter also cools down. Decomposing continues also when it is cold, but slower than when it is warm. Decomposing does not stop completely until the mass freezes. Freezing neither harms the composter nor the compost mass, but the composter fills up sooner than normally.

Fill the composter regularly also in the winter 

The best way to keep the composter in operation is to bring waste to it regularly. That is how the decomposing organisms are continuously provided with nutrition, and the heat that they generate keeps the process running. If the compost is at risk of freezing, you can heat it, for example, by putting a canister filled with hot water on top of or inside the compost mass. You can also use the Composting Accelerator,  which intensifies the composting process and speeds up the
decomposing of biowaste. 

Using bedding is important even in winter. Without it the waste packs up too tight and, after the air again warms up, decaying starts to cause odour problems.

You can adjust the ventilation of the Quick Composter using the adjustment disk above the emptying door. In winter the decomposing slows down, which means that consumption of oxygen in the composter is also reduced. Therefore, the adjustment disk can be in such a position, where the widest part of the adjustor is pointing upward. Then the air opening is only 20 % open.

The Quick Composter can and should be emptied even in winter. The emptied compost can either be put directly around the roots of the plants or in a heap to wait for the spring.
