Vechta based German biogas firm, WELTEC BIOPOWER has begun construction work on a small scale anaerobic digestion plant around 80 km north of the South Korean capital Seoul, in Gyeonggi-do province.
According to the company, as one of the world’s top 10 energy users, and with a population of 51 million and with few fossil fuel resources, South Korea is making major investments in renewable energy.
The new 450 kW biogas plant is scheduled to go live in the early summer of 2016 and will utilise WELTEC’s smart control technology that the company said will ensure a high level of efficiency at its second South Korean plant.
The precise plant control is claimed to enable a high degree of automation and optimum remote maintenance. The company added that it has also made the interface as user interface as friendly as possible.
"For this project, we programmed the control in Korean", said Harro Brons, project manager of WELTEC BIOPOWER. “Thus, the basis has been established for the smooth operation and the first steps to achieve South Korea's energy goals.
WELTEC said that the operator will feed around 100 tonnes of organic waste per day, constituting 70% pig manure, to produce approximately 4000 m³ of biogas in the stainless steel digester.
The digestate will be used as fertiliser wand ill be stored in two stainless-steel digestate storage units of 5590 m³ each until it is used.
The biogas will be used to operate a combined heat and power plant with an electrical output of 450 kW. WELTEC said that the power will be fed directly into the power grid and that the heat will be used for heating the operator’s buildings and for internal processes.
The company added that its previous record of having already completed a similar facility in South Korea was key to its selection for the project,. However, the customer's final decision was said to be based on the fact that the technical concept for the new project was custom-tailored to the region's special needs and South Korea's ecological goals.
"The sustainable waste disposal concept and the efficient processing of the input substances into high-nutrient fertiliser were decisive factors,” concluded Brons.
