process OF PRESECO composting plant

When the biowaste reaches the plant, support material is added to it in order to add carbon to the process and ensure the optimal structure of the mixture in terms of air and humidity. Such support material can be peat, woodchips, straw or even cardboard. The mixing of waste and support material is an automated process.

In the next phase, the biowaste pulp is fed into an aerated composting drum, where the temperature rises to 50-70°C as a result of microbial activity. Air is constantly blown into the drum, and its amount is regulated by monitoring exhaust gases and the process temperature. In this way, optimal conditions can be maintained throughout the process.

The composted, ready pulp is transferred automatically into the storage unit. The heat generated in the continuous process can be recovered and used for heating, drying or producing hot water, for example. The end product is clean and hygienic, and during storage, it will mature and cool down, becoming odour-free and fluffy. It is suitable as soil conditioner, among other applications.
