In October 2015, the construction work for an anaerobic digestion plant from German manufacturer WELTEC BIOPOWER started in South Korea. The plant site is located about 80 km north of the capital Seoul. The 450-kW biogas plant is to go live in summer of 2016. The highly developed technology with smart control will ensure a high level of efficiency of the second South Korean WELTEC plant.
Starting from the early summer of 2016, the operator will supply the stainless-steel digester with its capacity of almost 4,000 m³ with 100 tons of organic waste a day, whereof 70% are pig manure. This feedstock will be converted into biogas and high-quality fertiliser by anaerobic digestion. The fertiliser will be stored in two stainless-steel digestate storage units of 5,590 m³ each until it is used. The generated biogas will be used to operate a combined heat and power plant with an electrical output of 450 kilowatt. The power will be fed directly into the power grid. The heat will be used for heating the company buildings and for internal processes.
In South Korea, the optimum function of the components will be controlled by the WELTEC’s PLC-based LoMOS control.
