The German biogas specialist is supplying a turnkey solution based on high-quality stainless steel technologies for the 360-kilowatt plant. Weltec is in charge of the project’s engineering, execution, and full service, including biological analyses.

Construction at the operator’s headquarters in Tainan City, on the southwest coast of Taiwan, is scheduled to begin in 2023; commissioning is planned for 2024.

In addition to the electricity fed into the grid, part of it will be used for the plant’s own use. The heat from the biogas plant is also used to heat the operator’s production facilities directly at the plant and via a local heating network: among other things, it is used to supply a pigsty that is equipped by Weltec’s parent company WEDA Dammann & Westerkamp. The circular economy concept envisages using the pig manure produced as the main substrate for the operation of the biogas plant.

The stainless steel fermenters take into account the special requirements of the island state: due to its tectonic position, Taiwan experiences strong earthquakes with far-reaching consequences with above-average frequency. The special stainless steel construction and high stability of the biogas plant is adapted to the high earthquake probability and the local wind load specifications. Another advantage is that only a small amount of work is required for the on-site construction, as the project is intensively accompanied by the Weltec team from the headquarters in Vechta.
