Ancient Microbes Reduce Gas Bill and CO2
In-house gas production from recycled kitchen and garden waste with high yield and purity thanks to Bio-Boosting and Advanced Adsorption
By: Krajete GmbH
Composting kitchen and garden waste is resource-saving and sustainable – and, thanks to the latest developments, also capable of making a significant contribution to private, independent gas supplies. Key to this are recent developments from Krajete GmbH, which is now putting its years of experience in biological gas production and purification to work in the service of in-house gas production.
Bio-booster Brings Benefits
One of the cornerstones of the company's development is an innovative bio-booster technology. This uses sustainably produced hydrogen (H2), which is fed into the fermenter and stimulates special fermentation processes. Here, Krajete GmbH benefits from its world-leading expertise with so-called Achaea - microbes that can produce pure methane from CO2 and H2. This is an ability that other bacteria in conventional fermentation plants do not possess. These bacteria produce so-called biogas, which consists of half methane and half CO2. Usually, the CO2 is removed in complex purification processes and then released into the ambient air. Dr. Krajete, founder and CEO of Krajete GmbH, comments: "This is an expensive and climate-damaging waste. Our Achaea, on the other hand, act efficiently and in a climate-friendly way. They convert the CO2 to methane, increasing the gas yield to almost double."
The bio-booster process not "only" offers the advantage of increased gas production, but also allows existing photovoltaic systems to store the often surplus electricity produced in the form of high-quality hydrogen – instead of feeding it into the power grid for little money. Says Dr. Krajete: "Our technologies allow excess electricity to be used to electrolyse water into H2 and oxygen, and the hydrogen can then be used later to boost gas production by Achaea. This, after all, increases the methane yield enormously and thus turns the cheap surplus electricity into a supplier of valuable energy."
