Composting With Membrane

The CONAVERO membrane creates a controlled and monitored environment in which the microorganisms decompose the organic matter. The aeration system integrated into the base provides a steady flow of air through the waste to maintain aerobic conditions, creating an ideal environment for the composting process. The temperature rises to 55 - 65°C and ensures reliable hygienisation of the compost.
Depending on the composition of the input material, the ambient temperature and humidity, the logistics on the plant and any preceding and subsequent processes, the CONVAERO process and its capacity are adjusted to the desired degree of maturity (degree of rotting). Every product stage can be achieved, from fresh compost to fully matured compost. The material is covered for the entire duration of the process. Alternatively, it is possible to remove the covers during the later stabilisation and maturing phase.

The CONVAERO system is particularly effective in solving odour problems. These are one of the biggest challenges in waste treatment. It also prevents excessive water loss through evaporation while reducing the need for irrigation in relatively dry feedstock and dry climatic conditions. The leachate produced is collected by the aeration system and safely channelled away for interim storage or treatment. In addition, the energy consumption is relatively low compared to other intensive composting methods. The membranes prevent problems such as re-contamination by wind, birds and other animals. The waste is reliably hygienised and stabilised after a comparatively short process time. The system can be used for all waste with biogenic components. If the process is operated as bays or lines, even very difficult input materials such as sewage sludge or fermentation residues can be reliably processed.
