Biogas and Dimethyl Ether are Providing Water, Fertilizer for an Intelligent Smart Soil
Journal Title: Current Investigations in Agriculture and Current Research - Year 2018, Vol 3, Issue 3
Abstract
Biogas is well known in agriculture and food industry. In Austria we realized a project Hagenbrunn [1] nearby Vienna/ Austria, a biogas plant running on waste food and liquid biogenic waste. The electric power output is given with 1320kW ele, the thermal heat generation is given with 1800kW thermal heat realized with warm water (95 °C/60 °C), the substrate feed is given with 25, 000t/year, and the digestate coming out of the biogas plant is 35000t/year. The biogas generation of the different substrates, like waste food, grass, potatoes (e.g.) is done by measurements, testing and calculation and leads to the biogas generated by fermentation in a range of 700Nm³/h up to 800Nm³/h, with a methane concentration of 50% up to 65%. The biogas plant Hagenbrunn [1] has a deep influence on the way of irrigation, the way of fertilizing in agriculture and vine culture. The biogas plant Hagenbrunn [1] has a deep influence on the regional jobs, the regional companies, it is acting like a knot and center of competence and initiating a lot of spin offs. The main advantage of the biogas plant is using biogenic waste as input substrate and therefore the communities are glad to have a sink using and converting waste food and liquid biogenic waste to biogas. Biogas from the plant is only an intermediate step. In the first realization step biogas is converted to electricity and heat.
