Manure processing using supercritical gasification
Disposing or processing of manure or digestate is very costly. Processing manure has nonetheless become mandatory for Dutch farmers with limited arable land. By instead processing this manure or digestate using supercritical (hydrothermal) gasification, such costs can be considerably reduced. On top of this, the biomethane produced by the process is an extra revenue stream. The mineral concentrate that is also produced can be further upgraded or used as a natural fertilizer, replacing artificial fertilizers.
The Gensos supercritical gasification system can have a considerably positive impact on your business and its environment. It has many other benefits over conventional methods such as anaerobic digestion.
Convert wet waste into gas and minerals – With supercritical gasification nearly all of the organics are converted to gas, thus producing up to 50 percent more gas as compared to digestion. The minerals are separated as a small mineral concentrate that is rich in phosphorous, which could be used as a natural fertilizer.
Product flexibility – The gas that is produced is already compressed. In our system the gas is upgraded to biomethane quality so that it can be fed into the natural gas grid. It can also be converted to green electricity.
High thermal efficiency – Patented heat integration minimizes external energy needed to operate the process, which is essential for producing high gas yields from very wet waste.
Reliability – Patented reactor technology guarantees stable and reliable operation.
Reduces carbon and water footprint – The gas produced from waste is a renewable fuel that can replace fossil fuels. This closes the carbon cycle (making it carbon dioxide neutral) and reduces the carbon footprint of waste. The water that is produced can be cleaned to irrigation or proces water standards, reducing the water footprint of the waste. Pathogens and pharmaceuticals present in waste are inherently eliminated at supercritical temperatures.
Cost competitive – Depending on the waste composition, the total cost of ownership can be considerably reduced.
