Mobigas – The modular biogas plant on a container basis

The Mobigas biogas plants of Pöttinger Entsorgungstechnik GmbH & amp; Co KG consist of fermenter containers and technology containers and enable the recycling of organic wastes to be adapted to changing requirements. A ferment container of this new plant can hold up to 30 m² of organic waste and produce biogas in a three-stage process. The first phase is aerobic and the material is aerated in the fermenter. In the second phase, the ventilation is stopped and the anaerobic process begins. A percolate is sprayed onto the material and the fermenter container is heated by a floor heating system. Biogas production starts and takes about 4 weeks. When the material is evaluated, the fermenter container is again vented and the process is stopped. From the resulting gas, electric and thermal energy can be obtained directly by means of a combined heat and power unit. The entire system is controlled by the technical container, which includes gas analysis, gas storage and gas utilization. Material that has not been recycled in the gasification process can be recycled as compost, fertilizer or earthenware. The CO2 reduction is around 0.2 tonnes per ton of substrate used.
